+### 2026-10-24: 0.7.1 (rename fix)
+
+* Enter, Escape and clicking away end a rename again (projects on the home screen, library assets, versions). The fields took focus back before checking whether they had lost it.
+
+### 2026-10-24: 0.7.0 (images, research, plugins, fewer tokens)
+
+* Images in chat: paste from the clipboard (Cmd/Ctrl+V with an image-only clipboard now reaches the composer), thumbnails in the composer and in sent messages, a lightbox, image-only messages. Attachments are sent at most 1568 px (originals kept); `zoom_image` reads a region of the original.
+* Brief and finish: `ask_user` draws questions as a card of clickable answers (palette swatches, reference image tiles, the recommended answer marked). The chat rules ask for a brief before the first design, variables and components first, sizes from the agreed density, a short report and next steps as a card.
+* Web research (the composer's Web chip): `fetch_reference_images` (public addresses only, icons, logos and backdrops dropped, social cards last), a References gallery that dims what the agent did not keep; on Claude Code a Haiku `researcher` sub-agent does the searching.
+* Image generation, opt-in (Settings, Chat, Images): Codex (offered once when signed in with a ChatGPT plan), Google Flow through `gf`, or any command (`{prompt}`, `{aspect}`, `{ratio}`, `{out}`, passed as data).
+* Plugins (Settings, Plugins): Avataaars, DiceBear, Iconify, Lorem Picsum, Flags, QR codes, placed with `<x-plugin use="…">`, cached on disk. SVG import draws masked groups as images (Avataaars).
+* Tokens: lean Claude Code sessions (42.7k to 20.6k prompt tokens), deferred tool schemas and context editing on the API, a fresh session with a recap past 120k (or on demand from the meter), per-turn cost for resumed Claude Code sessions, a 1M context meter, a turn budget. Model and effort pickers for Claude Code.
+* Also: page switcher in the Chat top bar, steps stay folded while a turn runs (no flicker), `lint_design` asks 24 px targets on desktop screens, the installer keeps `papercraft-mcp` current.
+* Evidence: `src/mcp/{refs,imagegen}.rs`, `src/plugins.rs`, `src/io/svg_import.rs`, `src/ui/{chat,chat_msgs,chat_agents,settings}.rs`, `src/chat/{anthropic,claude_code}.rs`, `tests/chat_tools.rs`, `specs/chat-tokens/spec.md`.
+
+### 2026-10-22: 0.6.1 (agents via ACP, annotations)
+
+* Agents are found through the login shell's PATH (read once at startup, 3 s limit, merged with the app PATH and the usual folders), so an app opened from the Dock finds Claude Code, Codex and the rest. No install instructions anywhere; a missing agent shows Not found with Set path… and Docs.
+* ACP backend (`src/chat/acp.rs`): any agent that speaks the Agent Client Protocol over stdio, with PaperCraft's MCP server, streamed updates, permission flow, cancel and load. Registry as data in `src/chat/agents.rs`: native agents found on PATH, npx agents off until enabled, custom agents by name, command and arguments. Verified here: OpenCode works; Gemini CLI's server currently refuses ACP clients; Cursor needs `cursor-agent login`; Pi works through `pi-acp` after enabling.
+* Agent panel over the chat column (Detected, Enable via npx, Not found, API endpoints, Custom, search), a Connect an agent setup card, a sign-in card, and multiple `@ Selection` chips.
+* Settings → Chat redesigned: one agents list with details, endpoints, defaults, scrolling page on one label grid.
+* Send bug: a turn that cannot start keeps the typed text and shows an error row with Retry, never a silent no-op (`a_failed_start_keeps_the_text_and_shows_an_error`).
+* Annotations: notes with leader lines on a page, six categories with keys (style comes only from the category), project and per-page templates with built-ins and a Customize modal, view modes (⌘⇧A), Annotate tool (N), side view, inspector section, Annotate with AI, six MCP tools (`annotate` batches), and comments in `get_design_spec` and the code exports. Exports and Present leave annotations out.
+* Evidence: `src/chat/{path,agents,acp}.rs`, `src/ui/{chat_agents,annotations,annotations_canvas}.rs`, `src/model/annotation.rs`, `src/editor/annotations.rs`, `src/mcp/tools.rs`, `tests/annotations*.rs`, `specs/chat-agents/`, `specs/annotations/`, `docs/chat.md`, `docs/annotations.md`.
+
+### 2026-10-21: Chat mode
+
+* Chat layout next to the canvas (⌘J, `Design | Chat`), with three backends: Claude Code and Codex through their CLIs (`claude -p` stream-json, `codex exec --json`) against the app's MCP server, and the Anthropic API with a key in the OS credential store. One event stream for all three; tool calls run through the same MCP dispatch, so runs, review and revert behave as before.
+* Thread: markdown replies, thinking row, tool cards, step groups, plan from `TodoWrite`, approval for destructive tools on the API backend, run checkpoints with Restore to here, usage line and context meter, `@ Selection` and image attachments, Stop.
+* Chats live in the project's `chats/` folder. Settings → Chat holds CLI paths, the default backend and the API key.
+* Offline CLI fix: an offline save writes no camera, and a top-level shape created without a position goes to the next free spot instead of the origin.
+* Evidence: `src/chat/`, `src/ui/chat.rs`, `src/ui/chat_msgs.rs`, `src/ui/chat_md.rs`, `src/ui/settings.rs`, `src/mcp/exec.rs`, `tests/fixtures/chat/`, `specs/chat/`, `docs/chat.md`.
+
 ### 2026-10-21: Agent runs and change review

 * Agent editing calls group into runs, snapshot each edited page as `Before agent run N`, and end on 30 seconds idle, `finish_working_on_nodes`, or project switch. Runs persist under `runs/` and keep the newest 50.
 * Agent view lists runs and supports review, whole-run revert, per-change undo and accept all. Review adds canvas outlines and a finish toast; palette commands review or revert the last run.
 * Id-paired page diffs power review; History version compare UI remains todo. Completed with full restore (including variables, modes and tokens), tool edit classification, and wasm support.

+### 2026-10-21: Design libraries and offline CLI
+
+* Variables are now collections with modes, slash groups, four types and aliases, stored in `design.json` (project version 2; 0.4.0 refuses migrated projects). Each page keeps a derived cache; every edit is one undo step per page, and the page-only removals are gone. Per-page active mode per collection.
+* Fields bind to variables (stroke, text color, size, gap, padding, radius, font size, line height, opacity, visible) in the inspector and with `bind_variable`; gradients do not bind yet.
+* Instances work across pages (`component_key`, source page or library); deleting a main flags its instances.
+* Libraries: publish a snapshot (`library.json`), enable, update with review (overrides kept), disable, and keep working when the source is missing. Variables modal, Libraries modal and Assets view in the UI; `create_collection`, `delete_variables`, `bind_variable` and five `*_library` tools in MCP (61 tools).
+* `papercraft-cli call --offline` and `papercraft-cli shell` run the tools in-process on the project store, refuse a project the app has open, and fall back to the software adapter for screenshots. See `docs/agents.md`.
+* Evidence: `src/variables.rs`, `src/editor/design.rs`, `src/libraries.rs`, `src/cli.rs`, `tests/{libraries,cross_page_components,variables_ui,assets_panel,cli_offline}.rs`, specs in `specs/design-libraries/` and `specs/cli-offline/`.

+PaperCraft is an infinite-canvas design tool and whiteboard written in Rust (egui on wgpu). It runs as a desktop app with no account and no cloud: a project is a folder of JSON files on your disk. It also serves the Model Context Protocol and ships a CLI, so an agent such as Claude Code or Codex can read and edit the open canvas, screenshot the result and lint it, one undo step per tool call.

-<br>
+It is an alpha. It is good for building screens, design systems and sketches, and it is not a replacement for a mature design tool. See [Status and known limits](#status-and-known-limits).

 ## Features

+**Canvas and layout**
+* Frames with clipping, groups, vector shapes with the Pen and Bézier editing, boolean operations, gradients, image fills, strokes, per-corner radii, opacity and blend modes, drop shadows, rich text, smart guides, measurements, align and distribute.
+* Auto layout (direction, gap, padding, hug, fill, wrap, space-between) and constraints.
+* A layers tree you can drag to reorder or re-parent, an inspector with Design and Prototype tabs, and a command palette over every action, page and layer (⌘K).
+* Whiteboard mode: hand-drawn (rough.js-style) shapes, arrows bound to shapes, elbow connectors, sticky notes, freehand ink and a laser pointer on the same canvas.
+* Pages: each page is its own canvas with its own undo history and view.
+
+**Design systems**
+* **Components** work across pages and across projects. Edit a main component and its instances follow, except the properties an instance overrode.
+* **Shared libraries:** publish a project as a library, enable it in other projects, and take updates when it changes.
+* **Variables:** collections with modes, slash groups (`color/brand/primary`), types (color, number, string, boolean) and aliases. Fills, strokes, text color, size, gap, padding, radius, font size, line height, opacity and visibility bind to variables.
+* **Variables modal** (⌘⌥⇧V, or "Variables…" in the palette) to edit all of it; **Assets view** (side tab) with components grouped by name; **Libraries modal** to publish, enable and update.
+* Lint (`lint_design`) for contrast, the 4px grid, type scale, touch targets, default names and hard-coded colors, with auto-fix.
+* Design tokens out as CSS, JSON (W3C DTCG) or Tailwind `@theme`; code out as JSX with inline styles, Tailwind or HTML.

-### Themes
+**Prototyping and review**
+* Prototype links between frames and a **Present** mode that follows them with a camera glide.
+* **Version history:** named and automatic saved versions per page; rename, restore, delete.
+* **Agent runs:** editing tool calls group into a run. PaperCraft saves an auto-version before the first edit, lists the run, and lets you review it (added, changed and removed layers, outlined on the canvas), revert one change, revert the whole run or accept it.
+* **Comments** on the canvas.

-System, Light, Dark and the four Catppuccin flavours: Latte, Frappé, Macchiato and Mocha. Pick one in **View › Theme** or search "theme" in the ⌘K palette.
+**Sharing and platforms**
+* **Shared projects** through an optional relay (`papercraft-relay`); concurrent edits to a page are merged. Without a relay nothing leaves your machine.
+* **Themes:** System, Light, Dark and the four Catppuccin flavours (Latte, Frappé, Macchiato, Mocha).
+* **Web build** that runs the editor in the browser (`sh web/build.sh`, served by `papercraft-relay --static web`).
+* **Import and export:** Figma `.fig` files, `.excalidraw` scenes and libraries, SVG and images in; PNG (1 to 4x), SVG and vector PDF out, for a selection, each frame, a page or the whole project.

-### Projects and pages
+Projects live in `~/Documents/papercraft/<name>/` (`project.json`, one JSON file per page in `pages/`, plus `versions/`, `runs/` and library files). Work autosaves with atomic writes and files are versioned and migrated on load. `PAPERCRAFT_HOME` points to another folder.

-PaperCraft opens on a **home screen** of your projects (recents grid with thumbnails; New, Import, and Rename, Duplicate or Move to Trash from each card's ⋯ menu or right-click; restore from Trash). A project is a folder in `~/Documents/papercraft/<name>/` with `project.json` and one JSON file per page in `pages/`. Work autosaves about a second after each change with crash-safe atomic writes; files are versioned and older versions migrate on load. Set `PAPERCRAFT_HOME` to use another folder. If you used the app under its earlier name, `~/Documents/paper-rs` is still read when it is the only one that exists.
+## Agents

-Each project has any number of **pages** (the Pages list at the top of the left sidebar: + to add, double-click to rename, right-click to duplicate or delete, drag to reorder). Each page is its own infinite canvas with its own undo history and view. Copy and paste works between pages and projects.
+PaperCraft exposes **70 tools** (`src/mcp/tools.rs`) three ways. They run the same code inside the app.

-### File formats
-
-| Format | Use |
+| Way | Notes |
 |---|---|
-| Project folder (`project.json` + `pages/*.json`) | The native format. Plain, versioned JSON. |
-| `.papercraft` | A single-file document (`papercraft FILE.papercraft`, not autosaved). `--import` turns it into a project. |
-| `.paper-rs` | The earlier single-file extension. Old files still open. |
-| PNG, SVG, PDF | Export: selection, frames, page or all pages. PDF is vector, with gradients, images and blend modes. |
-| `.excalidraw`, `.excalidrawlib`, SVG, images | Import (drag and drop, ⌘O, or `--import`). |
-
-## Drive it with agents
-
-![A sign-in screen written by an agent through write_html](docs/screenshots/milestone7_mcp.png)
-
-PaperCraft serves the [Model Context Protocol](https://modelcontextprotocol.io) while it runs, so agents such as Claude Code and Codex can read and design on the open canvas. Every tool call runs through the editor like a user edit: one undo step per call, and the window repaints immediately. Tool names and arguments follow other design-tool MCP servers where there is an equivalent, so prompts written for them carry over.

-* **Streamable HTTP** (built into the app): `http://127.0.0.1:29980/mcp`. Loopback only; requests from browsers (with an `Origin` header) and foreign `Host` headers are rejected. `PAPERCRAFT_MCP_PORT=NNNN` changes the port; `PAPERCRAFT_MCP=0` turns the server off.
-* **stdio**: `papercraft-mcp` (built next to `papercraft`) relays stdio to the running app. It lists the tools even when the app is closed, and tells the agent to start PaperCraft if a call can't reach it.
-* **Shell**: `papercraft-cli` calls the same tools, so an agent with a terminal needs no schemas in its context.

-# or stdio through the bridge
-claude mcp add --scope user papercraft -- /path/to/papercraft-mcp
-```
-
-### Design tab
-
-The sidebar's **Design** tab (next to Layers and Library) lists the project's color variables as
-editable swatches, switches variable modes (for example the four Catppuccin flavours), and lists the
-page's components with Go to and Insert buttons. Editing a variable recolours every fill that follows it.
-
-### Codex
-
-```sh
+# Codex
 codex mcp add papercraft --url http://127.0.0.1:29980/mcp
-# or stdio
-codex mcp add papercraft -- /path/to/papercraft-mcp
 ```

-which writes this to `~/.codex/config.toml` (either form works):
+The main write tool is `write_html`: HTML with inline styles becomes layers (flexbox maps onto auto layout), and `update_styles` takes the same CSS as JSON. Other groups cover reading and screenshots, variables and bindings, components, libraries, icons, lint, diffs, export and agent-run bookkeeping. The full list is `papercraft-cli list`; each schema is `papercraft-cli schema <tool>`; the reference is [skills/papercraft/references/tools.md](skills/papercraft/references/tools.md).

-```toml
-[mcp_servers.papercraft]
-url = "http://127.0.0.1:29980/mcp"
-# command = "/path/to/papercraft-mcp"
-```
+### Without the app

-Then ask the agent something like *"In PaperCraft, create a 390×844 mobile artboard and design a sign-in screen"*, or *"draw a flowchart of our deploy process on a new page, hand-drawn style"*. The [`papercraft` and `papercraft-design` agent skills](skills) teach an agent the workflow (build, screenshot, lint, fix) and design rules; [docs/agents.md](docs/agents.md) has the full guide.
-
-### Shell (no MCP client needed)
-
-The app must be running with a project open.
+`papercraft-cli` works with PaperCraft closed. When nothing answers on the port, or with `--offline`, tools run inside the CLI on the project store and every editing call is saved; the project opens normally in the app later. With the app open on a project, `--offline` on that same project is refused, so two writers never share a folder. Screenshots use the GPU, or the software adapter when there is none.

 ```sh
-papercraft-cli list                          # tool names, one line each (works offline)
-papercraft-cli schema write_html             # one tool's full schema
-papercraft-cli call get_basic_info
-papercraft-cli call create_artboard '{"name":"Hero","styles":{"width":"800px","height":"400px"}}'
-echo '{"nodeId":"12"}' | papercraft-cli call get_screenshot - --out hero.png
+papercraft-cli call create_file '{"name":"Demo"}' --offline
+papercraft-cli call get_screenshot '{"nodeId":"abc123:1"}' --project Demo -o card.png
 ```

-Text goes to stdout, images are saved to `--out` (default `<tool>.png`) and the path is printed, and the exit status is 1 on a tool error or when the app isn't running.
-
-### Tools
-
-| Group | Tools |
-|---|---|
-| Projects & pages | `list_resources`, `open_file`, `create_file`, `create_page`, `rename_pages`, `delete_pages` |
-| Read | `get_basic_info`, `get_selection`, `get_node_info`, `get_children`, `get_tree_summary`, `get_computed_styles`, `get_jsx`, `find_nodes`, `get_fill_image`, `get_font_family_info`, `get_guide` |
-| See | `get_screenshot` (PNG image content of a node or the page), `export` (PNG/SVG/PDF files), `export_combined_pdf` |
-| Write | `create_artboard`, `write_html`, `update_styles`, `set_text_content`, `rename_nodes`, `duplicate_nodes`, `move_nodes`, `delete_nodes`, `finish_working_on_nodes` (saves) |
-| Whiteboard and session | `create_shape` (rectangles, ellipses, diamonds, stars, stickies, text, lines, arrows bound to shapes), `select_nodes`, `undo`, `redo` |
-| Design system | `get_variables`, `set_variables`, `set_variable_mode`, `get_components`, `create_component`, `create_instance`, `search_icons`, `lint_design` |
-
-`write_html` takes HTML with inline styles: flexbox (`display:flex`, direction, gap, padding, alignment, `flex-grow`, wrap) and block stacking map onto auto layout with CSS's stretch rules; text gets size, weight, italic, color, line height, letter spacing, alignment and rich-text runs (`<b>`, `<i>`, `<span style>`); boxes get backgrounds (colors, gradients, images), borders, radii, opacity and blend modes; `<img>` takes local paths or `data:` URIs and `<svg>` is imported as vectors. `update_styles` takes the same CSS as JSON, plus the hand-drawn keys `sketch`, `roughness`, `fillStyle`, `strokeStyle`. Node ids look like `3fa9c1:14` (page and node); `pageId` lets an agent work on another page without switching the user's view. The full reference is in [skills/papercraft/references/tools.md](skills/papercraft/references/tools.md).
-
-## Design systems: variables, components, icons
-
-Agents (and `papercraft-cli`) get the pieces of a design system, so files aren't a pile of hex codes and copies:
+`papercraft-cli shell` keeps one session open and reads a script from stdin. `:watch on` re-renders the artboard last edited to `preview.png` after every editing call (and shows it inline on iTerm2, WezTerm and kitty).

 ```sh
-papercraft-cli call set_variables '{"variables":{"surface":"#313244","accent":"#cba6f7"}}'
-papercraft-cli call write_html '{"targetNodeId":"root","mode":"insert-children","html":"<div style=\"background:var(--surface)\">…</div>"}'
-papercraft-cli call create_component '{"nodeId":"<frame>","name":"Button / Primary"}'
-papercraft-cli call create_instance  '{"componentId":"<id>","parentId":"<frame>"}'   # then set_text_content on its layers
-papercraft-cli call lint_design '{"nodeId":"<frame>"}'                               # contrast, grid, type scale, names
-papercraft-cli icons add phosphor lucide      # open icon sets from npm, with their licences
-papercraft-cli icons search arrow left
-# in write_html: <x-paper-icon name="phosphor:gear" size="20" color="var(--accent)"/>
+papercraft-cli shell --offline --project Demo <<'EOF'
+set_variables {"variables":{"bg":"#1e1e2e","surface":"#313244","text":"#cdd6f4","accent":"#cba6f7"}}
+:watch on
+write_html {
+  "targetNodeId": "abc123:1",
+  "mode": "insert-children",
+  "html": "<div style='font-size:28px;color:var(--text)'>Welcome back</div>"
+}
+EOF
 ```

-* **Variables** are named colors per project (`get_variables`, `set_variables`). A fill or text color written as `var(--name)` stays linked; `set_variables` moves every linked fill on every page in one undoable step, and the link is saved in the file. `set_variables` with a `mode` stores one set of values per mode (Light, Dark) and `set_variable_mode` switches the whole project. Strokes and gradients keep fixed colors; fill-based icon sets (Phosphor, Material) follow variables, stroke sets (Lucide) don't.
-* **Components** (`create_component`, `create_instance`, `get_components`, `<x-paper-instance>`): edit the main component and every instance follows, except what an instance overrode (text, fills, size, ... are marked automatically when set through `set_text_content` / `update_styles`). Components and their instances live on one page.
-* **Icons** live in `<data dir>/papercraft/icons/<set>/` (override with `PAPERCRAFT_ICONS`). Sets: Lucide (ISC), Tabler (MIT), Phosphor (MIT), Heroicons (MIT), Material Symbols (Apache-2.0); each keeps its licence file. `examples/taskflow.py` builds an 8-screen app with all three.
-* **Lint** (`lint_design`) checks WCAG contrast, spacing on a 4px grid, the type scale, text under 12px, touch targets under 44px, default layer names and hard-coded colors that should be variables, and says how to fix each.

+### Chat
+
+Chat mode (⌘J, or `Design | Chat` in the top bar) puts a conversation next to the canvas. It runs Claude Code and Codex through their CLIs, any agent that speaks the Agent Client Protocol (ACP, such as OpenCode, Gemini CLI or Cursor) found on your PATH, or the Anthropic API with your own key. It shows tool calls, checkpoints and run review in the thread. Chats are saved in the project's `chats/` folder. See [docs/chat.md](docs/chat.md).

+  <sub>Chat mode with a finished agent run: review, revert or accept from the thread.</sub>
+</p>
+
+### Annotations
+
+Annotations are notes that explain a design in place: business rules, behaviour, data sources, accessibility and dev notes, each a numbered card with a leader line to its layer. Categories set the look, templates say which notes a page wants (product spec, dev handoff, accessibility review and more), and the view cycles between full notes, badges and hidden with ⌘⇧A. Exports and Present mode leave them out. Agents add them in one `annotate` call. See [docs/annotations.md](docs/annotations.md).
+
+### Skills
+
+[`skills/`](skills) holds agent skills: `papercraft` (the build, screenshot, lint, fix loop and tool cheat sheet), `papercraft-design` (design-quality rules) and `papercraft-critique`. [docs/agents.md](docs/agents.md) is the full guide: install, registering with agents, scripts, runs and review, safety. [docs/design-system.md](docs/design-system.md) covers variables, components and libraries.

+cargo test --no-fail-fast
+PAPERCRAFT_REQUIRE_GPU=1 cargo test        # fail instead of skip when there is no GPU adapter
 cargo test --release --test perf -- --nocapture   # 10k-element frame timings
 ```

-The scenario tests drive the editor with synthetic pointer and keyboard events; `tests/mcp.rs` exercises every MCP tool on a headless session, then through an rmcp client over HTTP and through the `papercraft-mcp` stdio bridge. The SVG export is rasterized with resvg and compared with the GPU render.

 * **No rotation.** Nodes are axis-aligned boxes; rotated imports are baked into paths.
-* **Text** is Inter only (regular, bold, italic, bold italic) with no shaping: no ligatures, complex scripts or RTL, and no font picker. IME preedit is not displayed (committed text works).
-* **Rendering approximations.** Frame clipping is a rectangle, so rounded frames don't clip their corners. Group opacity multiplies into children. Overlay, dodge, burn, light, difference, exclusion and the HSL blend modes draw as Normal on the canvas (they are exact in SVG export).
-* **Booleans are destructive**: the result is a new vector path with flattened curves.
-* **Variables are colors only** and apply to fills and text color; strokes and gradients keep fixed colors.
-* **`write_html`** ignores margin, grid, tables, shadows and transforms (it reports them as `ignoredStyles`). Remote `http(s)` images aren't fetched; pass a local path or a `data:` URI.
-* **MCP**: one project is open at a time, so `fileId` must name the open project. Moving or duplicating layers between pages isn't supported.
-* **Pen pressure.** winit 0.30 does not expose tablet pressure for pen events that arrive as mouse input, which is common with macOS and Wacom tablets. Otherwise it is simulated from stroke velocity.
-* **Linux file dialogs** need an XDG desktop portal. The headless CLI is unaffected.
-* **PDF** text is outlined (not selectable).

-PaperCraft is an independent, clean-room-style reimplementation. It was reverse engineered from [Paper](https://paper.design) by studying the behavior of the Paper desktop app (`analysis/PAPER_ARCHITECTURE.md`) with [REA](https://github.com/morluto/rea) and Claude Code; Figma and Excalidraw were studied from their public docs and, for Excalidraw, its MIT source (`analysis/`). Only *behavior* was studied: no Paper or Figma code, shaders, icons, fonts or assets are used or committed. PaperCraft is not affiliated with, sponsored by or endorsed by Paper or Figma; those names are used only to describe the workflows it is compatible with.

+PaperCraft exposes one set of 70 tools three ways. They all run the same code inside the app, so an agent sees what you see and every call is one undo step.

 | Way | Use it when | Needs the app running |
 |---|---|---|
 | MCP over HTTP, `http://127.0.0.1:29980/mcp` | the agent client speaks MCP (Claude Code, Codex, pi) | yes |
 | MCP over stdio, `papercraft-mcp` | the client only starts stdio servers | for calls; `tools/list` works offline |

+| Shell, `papercraft-cli` | the agent has a terminal and you want no tool schemas in its context | for `call`; `list`, `schema` and `icons` work offline (with the app running, `list` and `schema` show the app's tools) |
+
+If you would rather talk to the agent inside the app, Chat mode (⌘J, or `Design | Chat` in the top bar) is the in-app alternative. It runs Claude Code or Codex through their CLIs against the same MCP server, ACP agents such as OpenCode or Gemini CLI, or the Anthropic API with your own key, and keeps the conversation next to the canvas, with the same runs, review and revert. The setup and the thread are in [chat.md](chat.md). The rest of this guide covers driving the app from your own terminal or agent client.

 ## Install

@@ -75,6 +77,61 @@ papercraft-cli call finish_working_on_nodes '{"nodeIds":["abc123:1"]}'

 Pass JSON inline, or `-` to read it from stdin (best for HTML, which is full of quotes; `jq -Rs` can wrap a file into the right JSON). Text results go to stdout. Images are saved to `--out` (default `<tool>.png`) and the path is printed.

+## Without the app
+
+`papercraft-cli` also works with PaperCraft closed (a server, CI, a headless box). When nothing answers on the port, or with `--offline`, tools run inside the CLI on the project store (`$PAPERCRAFT_HOME`, else the default folder) and every editing call is saved. Projects made this way open normally in the app.
+
+```sh
+papercraft-cli call create_file '{"name":"Demo"}'          # -> fileId
+papercraft-cli call create_artboard '{"name":"Card"}' --project Demo
+papercraft-cli call get_screenshot '{"nodeId":"abc123:1"}' --project Demo -o card.png
+```
+
+`--project <name|id|path>` opens that project first; without it the most recently modified one is used. With the app open on a project, plain `call` goes to the app, and `--offline` on that same project is refused ("PaperCraft has this project open") so two writers never share a folder. Screenshots need a GPU adapter; with none, the software adapter is tried, and if that fails the image tools return an error while all other tools work.
+
+### Shell and scripts
+
+When `call` or `shell` reaches the app and the app is another version, the CLI prints once on stderr, for example `papercraft-cli 0.6.1 ≠ app 0.6.2; reinstall the CLI`. `list` and `schema` read the running app's tool list, so tools newer than the CLI still show; with the app closed they use the CLI's built-in list.
+
+`papercraft-cli shell [--project X] [--offline]` keeps one session open (offline, one in-process project; otherwise the app). A line is `<tool> <json>` (JSON may span lines until its braces close) or a command: `:help :tools :schema <tool> :open <project> :pages :page <name|id> :shot [nodeId] [file] :undo :redo :save :watch on|off :quit`. `:watch on` renders the artboard last edited to `preview.png` after each editing call, shown inline on iTerm2, WezTerm and kitty. Input is plain stdin (no line editing or history; use `rlwrap` for that). Piped input prints no prompt and exits 1 if any line failed, listing the line numbers on stderr.
+
+```sh
+papercraft-cli shell --offline --project Demo <<'EOF'
+# build a card
+create_artboard {"name":"Card","styles":{"width":"320px","height":"180px","backgroundColor":"#1e1e2e"}}

+* Variables: `get_variables` and `set_variables` take collections, groups (`color/brand/primary`), types (`color`, `number`, `string`, `boolean`), `mode`, `alias`, `description` and `hidden`; the old `{"name":"#hex"}` call still works and lands in the first collection. `create_collection` makes a collection with modes, `delete_variables` removes by name (refuses aliased ones unless `force`), `bind_variable` binds or detaches a field of layers (`stroke`, `text-color`, `width`, `height`, `gap`, `padding`, `radius`, `font-size`, `line-height`, `opacity`, `visible`).
+* Components: `get_components` lists mains of every page and enabled library with a `componentKey`; `create_instance` and `swap_instance` accept a main from any page or library (`componentId` or `componentKey`).
+* Libraries: `publish_library`, `list_libraries`, `enable_library`, `update_library`, `disable_library`. They work offline too, on the project store.
+
+## Seeing what the user sees
+
+* `get_basic_info` and `get_selection` include `viewport: {pageId, rect: [x, y, w, h], zoom}`: the page the user is viewing and the world rect on screen.
+* `set_viewport {pageId?, nodeIds? | rect?, zoom?, padding?, force?}` switches the user's page (as the page list does) and fits the nodes or rect, or centres them at an explicit `zoom` (0.01 to 256; `select_nodes {zoom: true}` stops at 100%). While the user is panning or zooming (10 s after their last camera move) it is refused with "user is moving the canvas", unless `force: true`.
+* `find_nodes {textValue}` finds text layers containing the phrase on every page (or `pageId`), ignoring case and line breaks; `*` wildcards match the whole value instead. `get_tree_summary {nodeId, fullText: true}` prints every text layer's complete text, for copy review across screens.
+* `get_screenshot {nodeId, annotations: true}` draws the notes on the captured layers (cards, number badges, leader lines), so an agent can check note placement.
+
+## Annotation tools
+
+* `annotate {pageId?, notes: [{node, text, type?}]}` adds many notes in one undo step. `node` is a node id or an exact layer name; the first line of `text` is the label and the rest the body; `type` is a category key (default `rule`) that the page's template must enable. Placement is automatic. `annotate {tidy: true, frame?}` with no notes re-lays-out the existing notes and returns `{"tidied": n}`, the number of notes it moved.
+* `get_annotation_template {pageId?}` returns the allowed types with their guidance and fields. Call it once before `annotate`.
+* `set_annotation_template {template, scope?: "page" | "project", pageId?}` switches the template by id or name.
+* `upsert_annotation_template {template: {id?, name, display?, categories: [{key, enabled?, guidance?, fields?}]}, categories?: [{key, name, color, icon}], setAs?: "project" | "page", pageId?}` creates or replaces a template and its category styles in one undo step. `delete_annotation_template {template}` removes one (the last stays).
+* `get_annotations {nodeId?, pageId?, full?}` reads notes as `[number, node, type, text]` rows.
+* `update_annotation {id | ref, text?, type?}` and `delete_annotations {ids}` take ids or references such as `Sign in #3`.
+
+See [annotations.md](annotations.md) for categories, templates and what the notes look like.

 ## Safety

 The server listens on loopback only, rejects requests that carry an `Origin` header (browsers) and foreign `Host` headers. Anything on your machine that can reach `127.0.0.1:29980` can edit the open project, so do not forward the port. Undo (⌘Z, or the `undo` tool) reverts any agent edit.

+# Annotations
+
+An annotation is a note that explains a design in place: a business rule, a behaviour, where the data comes from, an accessibility gap. Each note is a small card with a number, a category, a label and an optional body, joined to its layer by a leader line. Teams use them for review and handoff, and turn them off for presenting.
+
+Annotations live on a page and are saved with it (the `annotations` list in the page file). Pages without any load and save exactly as before. Categories and templates are project-wide and live in `design.json`.
+
+## Categories
+
+Every note has one category. The category is the only thing that sets how a note looks: its icon, colour and badge come from the category, and a note stores none of them. Change a category's colour or icon and every note in it changes.
+
+Each category has a short type key. Agents and the Annotate popover use the key; the UI shows the name.
+
+| Key | Name | Icon | Colour | Use for |
+|---|---|---|---|---|
+| `rule` | Business rule | scale | violet `#7c5cff` | the rule or constraint the part enforces |
+| `behaviour` | Behaviour | zap | blue `#2f80ed` | states, transitions, edge cases |
+| `content` | Content | type | green `#1fa87a` | copy, tone, length |
+| `data` | Data | database | amber `#e08a1e` | where a value comes from |
+| `a11y` | Accessibility | accessibility | pink `#d94f8a` | focus, labels, contrast, reading order |
+| `dev` | Dev note | code | grey `#6b7280` | implementation notes for engineers |
+
+You can add categories, rename them, change their key, colour and icon, and write guidance for each one in the Customize modal. A custom category gets a key too.
+
+## Templates
+
+A template says which kinds of notes a page wants, and what each note should contain. The project has a default template; a page can use its own instead.
+
+Built-in templates are editable copies, not locked. Each category in a template has enabled or not, guidance (a short prompt for what the note should say) and optional fields (structured lines such as `Owner`).
+
+| Template | Categories | Fields |
+|---|---|---|
+| Product spec | rule, behaviour, content, data | none |
+| Dev handoff | behaviour, data, dev, a11y | none |
+| Accessibility review | a11y | Issue, WCAG, Fix |
+| Content review | content | Tone, Max length |
+| Minimal | rule | none |
+
+Pick the project default or "This page" from the template chips at the top of the Annotations side view. Built-ins can be reset; custom templates can be deleted. Duplicate copies any template so you can change it.
+
+**Customize…** (side view) opens the template editor: name, display (full notes or badges), the enabled categories, the guidance and fields of each. Changes to categories apply to the whole project.
+
+The Annotate popover offers only the enabled categories of the active template, and shows each field as a labelled line. A field is stored as a `Name: value` line at the top of the note's body. Agents get the same rule: `annotate` refuses a type the template disables and lists the allowed keys.
+
+## View modes
+
+Three levels, all view state. They are not saved in the design and not undoable.
+
+* **Full**: every note shows its label and the first lines of its body. Below 60% zoom notes show as badges, so cards never spill over the design; zoom in to read them.
+* **Badges**: only the number badges are shown.
+* **Hidden**: nothing is drawn.
+
+`⌘⇧A` (View → Annotations) cycles Full → Badges → Hidden → Full. The starting mode follows the template's display setting until you change it.
+
+Two finer controls:
+
+* **Per note**: collapse a note to its number badge; click the badge to expand it again.
+* **Per category**: show or hide a category from the category filter in the side view.
+
+Annotations are drawn as an overlay on the canvas only. Exports (PNG, SVG, PDF) and Present mode never include them. There is no option to include them in an export yet.
+
+## Annotate tool
+
+Press `N` for the Annotate tool, then click a layer. The New annotation popover opens beside it with:
+
+* Category, from the template's enabled categories.
+* Label, up to 40 characters. The popover shows the count.
+* The template's fields, if any.
+* A note, in Markdown.
+
+Save creates the note with its leader line to the layer's side; Cancel discards it. You can also select layers, right-click, and choose **Annotate**.
+
+Each note's leader line starts at the note card and ends at the anchor on the target. The card and the anchor are stored relative to the target, so moving or resizing the layer keeps the note attached. Drag a card to move it; the line re-routes.
+
+If the target is deleted, the note stays where it was in the side view's **Detached** group, with a warning badge.
+
+## Annotations side view
+
+The side view lists the page's notes:
+
+* Grouped by top-level frame, plus **Page** (notes on no frame) and **Detached**.
+* Each row shows the number, the category chip and the label. Click a row to select the layer and zoom to it.
+* The category filter shows or hides categories.
+* Edit a note inline, or delete it. Edits are one undo step each.
+* **Add annotation** opens the popover for the current selection.
+* **Annotate with AI** puts a prompt in the Chat composer, unsent, with the selected frame (or the page) as a chip. The prompt asks the agent to read the template with `get_annotation_template` and add all the notes in one `annotate` call. It needs a saved project and Chat mode.
+
+Numbers run per frame in reading order (top to bottom, then left to right), so a frame reads 1, 2, 3. Notes on no frame are numbered after that, from 1.
+
+## Inspector
+
+When a single layer is selected, the inspector has an Annotations section. It lists that layer's notes, with edit and delete, and an Add annotation button. The note's anchor is one of the four sides of the target (Top, Right, Bottom, Left) with a position along it.
+
+## Agents
+
+Agents work with notes through six MCP tools, all in `src/mcp/tools.rs`. They are one undo step per call and appear in `edits_doc`, so a run that only adds notes still gets a Review card (a "Notes" group, counted as added, changed or removed), and Revert removes them.
+
+| Tool | What it does |
+|---|---|
+| `get_annotation_template` | Reads the template: `[type key, guidance, field names]` for each enabled type. Call it once before `annotate`. |
+| `set_annotation_template` | Switches the template by id or name, for one page (default) or the project (`scope: "project"`). |
+| `upsert_annotation_template` | Creates or replaces a template, and creates or restyles categories in the same call (`categories: [{key, name, color, icon}]`). `setAs: "project"` or `"page"` makes it the default or the page override. Returns `{id, name, types}`. |
+| `delete_annotation_template` | Deletes a template by id or name. The last template stays. |
+| `annotate` | Adds many notes at once. Each note names a node id or an exact layer name on the page, a `text` and a `type` (default `rule`). |
+| `get_annotations` | Reads notes as `[number, nodeName, type, text]` rows (text capped at 120 characters). `full: true` returns complete objects; `nodeId` limits to a subtree; `pageId` picks another page. |
+| `update_annotation` | Changes the text or type of one note, by `id` or by reference such as `Sign in #3`. |
+| `delete_annotations` | Deletes notes by ids or references such as `Sign in #3`. |
+
+Custom template with a new category, used on the current page:
+
+```json
+{
+  "template": {"name": "Legal review", "categories": [
+    {"key": "legal", "guidance": "Legal risk this part carries.", "fields": ["Owner", "Law"]},
+    {"key": "rule"}]},
+  "categories": [{"key": "legal", "name": "Legal", "color": "#aa3355", "icon": "scale"}],
+  "setAs": "page"
+}
+```
+
+`icon` must be one of the built-in icon names (an unknown name lists them). Every key in the template must exist, either already or in `categories`. The template and category edit is one undo step; `setAs: "page"` adds a second.
+
+For `annotate` and `update_annotation`, the first line of `text` is the label and the rest is the body. There are no positions, icons or colours: PaperCraft places each note beside its target, outside the frame, stacked so none overlap. `annotate` is all or nothing: if one note is refused (an unknown layer, or a type the template disables), none is added and the error lists the allowed keys.
+
+Batched call, on a page whose template is Product spec:
+
+```json
+{
+  "notes": [
+    {"node": "Sign in", "type": "rule", "text": "Lock after 5 failed tries\nLocks for 15 minutes, then resets."},
+    {"node": "Email field", "type": "data", "text": "Source: users.email\nValidated on blur"},
+    {"node": "Submit", "type": "behaviour", "text": "Disabled until both fields are valid\nSpinner while the request runs"}
+  ]
+}
+```
+
+The reply is one row per note, `[number, node, type, label]`. Then `get_annotations {}` reads them back, and `delete_annotations {"ids":["Sign in #3"]}` removes one by its frame reference.
+
+`annotate {"tidy": true}` with no notes re-runs placement for every note on the page (or on `frame`) in one undo step and returns `{"tidied": n}`, the number of notes it moved; `0` means the layout was already tidy.
+
+To see the notes, `get_screenshot {"nodeId": "<frame>", "annotations": true}` draws the cards, number badges and leader lines of the notes whose target is inside the captured layers, placed and routed as on the canvas (full cards, scale 1). The image grows to include the cards. Without `annotations`, or with `false`, the screenshot is the same as before.
+
+**Handoff.** `get_design_spec` and the code exports (`get_jsx`) include the notes of the frame as comments. Each note is one line, `// 1 Business rule: Lock after 5 failed tries`, with its body lines as more `//` lines, so code generated from a frame carries the rules next to the markup.
+
+## Storage
+
+* The page file has an `annotations` list. Each note holds its target (or a point, when it has none), its anchor, label, body, category, position, author (`user` or `agent`) and creation time. A note whose target is gone is marked `detached`.
+* `design.json` holds the categories and the templates, with the project default. A page may name its own template.
+* Old projects load unchanged. A page without annotations saves byte-identical to before.

+# Chat mode
+
+Chat mode puts a conversation with an agent next to the canvas. Press ⌘J, or use the `Design | Chat` switch in the top bar, to turn it on. The chat column sits on the left (420 to 640 px, 480 by default, resizable) and the live canvas fills the rest. The layers and inspector are hidden; the inspector can be opened as a narrow overlay on the canvas's right edge. Design mode works as before, and a chat keeps running in the background when you switch back.
+
+The mode is remembered per project. Entering a project that was last left in Chat mode opens in Chat mode and shows its newest chat.
+
+Chat mode is native only. The web build shows the switch disabled with a note.
+
+## Backends
+
+Chat drives the same tools as an agent connected over MCP, so the edits, runs, undo and revert behave the same whichever backend you use. There are three ways in: two CLIs that PaperCraft talks to directly, any agent that speaks ACP, and API endpoints.
+
+**Claude Code** runs `claude -p` with streaming JSON in and out. PaperCraft writes an MCP config that points the CLI at the app's own server on `127.0.0.1`, allows the `mcp__papercraft__*` tools, and passes `--strict-mcp-config`, so the CLI sees only PaperCraft's server. The PaperCraft skill text goes in through `--append-system-prompt-file`. The working directory is the project folder. Follow-up messages resume the CLI session by its id, so the agent keeps its context.
+
+**Codex** runs `codex exec --json` in the project folder. The PaperCraft server is added with a `-c mcp_servers.papercraft.url=...` override, and its tools are pre-approved (`default_tools_approval_mode="approve"`), so Codex does not stop to ask for each one. The PaperCraft instructions are prepended to the first prompt of a chat; resumed sessions do not repeat them. Follow-ups resume the Codex session the same way.
+
+**ACP agents** run any agent that speaks the Agent Client Protocol (https://agentclientprotocol.com) over stdio. PaperCraft starts the agent once per turn, sends `initialize` and `session/new` with the project folder as the working directory, and passes PaperCraft's MCP server: over HTTP when the agent supports it, otherwise through the bundled `papercraft-mcp` stdio bridge. The prompt goes out as `session/prompt`, and the agent's streamed updates become the same thread as the other backends: text, thinking, tool cards and the plan. Stop sends `session/cancel`. Follow-ups resume with `session/load` when the agent supports it. ACP has no system prompt field, so the PaperCraft instructions go in front of the first prompt.
+
+The ACP agents PaperCraft knows about, and what was checked on the development Mac:
+
+* **OpenCode** (`opencode acp`): works.
+* **Gemini CLI** (`gemini --acp`): found and started, but its server currently refuses ACP clients, so turns fail with the agent's error until Google changes that.
+* **Cursor** (`cursor-agent acp`): sign in first with `cursor-agent login`.
+* **Pi** (`pi-acp`, an adapter run through `npx`): enable it once in the agent panel or Settings, then it works like the others.
+* **Goose, Kimi, Devin, Junie, Mistral Vibe, Hermes, OpenHands, Stakpak, VT Code, Poolside, Droid**: started with the command their own docs give. They are not all verified here.
+* **Claude Code and Codex ACP adapters** (`npx`): listed under Enable via npx. Claude Code and Codex themselves use the direct backends above.
+
+Agents that run through `npx` are off until you enable them, because enabling runs code that npx fetches from npm.
+
+ACP permissions: PaperCraft's own tools run without asking, except the destructive ones listed under Approval below. Any other tool the agent asks to run (its own shell or file tools, for example) shows an approval card with Approve or Deny in the thread, and Deny is sent back to the agent.
+
+**Custom agents** are your own ACP agents: a name, a command (a program name on the resolved `PATH`, or a full path) and arguments. The arguments are split on spaces, with no quoting. Custom agents appear under Custom in the agent panel and in Settings → Chat.
+
+**API endpoints** call a model over HTTPS with your own key. Settings → Chat holds a list of endpoints, each with a name, a format, a base URL, a model and an optional key. The app's tool list is sent as the API tools, and every tool call runs through the same code path as an MCP call on the UI thread. The loop continues until the model ends its turn, for up to 40 tool rounds per message.
+
+* **Format**: `Anthropic` is the Messages API (`POST {base}/v1/messages`, `x-api-key`). `OpenAI` is Chat Completions (`POST {base}/chat/completions`, `Authorization: Bearer`, streaming `choices[].delta`, tools as `{"type":"function",...}`, tool results as `tool` messages). Both give the same thread: text, tool cards, approvals, Stop, the usage line.
+* **Base URL and model** are free text, for example `https://api.anthropic.com`, any Anthropic-compatible URL, or `http://127.0.0.1:11434/v1`. The key is optional, so local servers need none.
+* A default endpoint named `Anthropic` (`https://api.anthropic.com`, `claude-opus-5-5`) exists from the start, so the first run needs only a key.
+* The agent panel lists Detected agents, API endpoints and Custom agents (see Setup). Each chat remembers its backend.
+* **Claude-only fields** (effort, the thinking summary, the refusal fallback and its beta header, eager tool-input streaming, prompt-cache breakpoints) are sent only when the base URL host is `api.anthropic.com`. For that host the model menu offers `claude-opus-5-5`, `claude-sonnet-5-5` and `claude-haiku-5-5`, effort is `medium` by default (`low` and `high` in the menu), and the Thinking row shows the summary. Every other endpoint gets a plain request. Missing `usage`, thinking or cache fields in the reply are fine.
+* **OpenAI format and images**: attached images are sent as `image_url` data URIs. A tool message in this format carries text only, so a tool result with an image (such as `get_screenshot`) goes back as the text `[image omitted]`, and the image follows as an extra user message in the same round.
+* **Usage line**: input, output and cached tokens, as the server reports them; nothing when it reports none. A cost estimate shows only for the Claude models in the small price table in `src/chat/endpoint.rs`. It is not a bill.
+* `ANTHROPIC_API_KEY` in the environment is used for `api.anthropic.com` when no key is stored. `PAPERCRAFT_ANTHROPIC_BASE_URL` points Anthropic-format requests at another URL (for tests and proxies).
+
+## Setup
+
+### Finding agents
+
+Chat finds agents the way your terminal does. At startup PaperCraft reads your login shell's `PATH` once, off the UI thread (`$SHELL -l`, 3 s limit), and merges it with the app's own `PATH` and the usual folders (`~/.local/bin`, `/opt/homebrew/bin`, `/usr/local/bin`, `~/.cargo/bin`, `~/.bun/bin`, `~/.npm-global/bin`, Volta and nvm). Detection and the agent processes both use that merged `PATH`. This is why an agent installed under `~/.local/bin` or Homebrew is found even when PaperCraft was opened from the Dock.
+
+A row shows a version when the agent reports one. A program with the right name that is not the agent (for example the `goose` database migration tool, which shares its name with Block's Goose agent) shows `Wrong program` with its path, not a false Ready.
+
+PaperCraft never shows install commands. An agent that is not found shows `Not found`, with `Set path…` (opens Settings) and `Docs` (the agent's own documentation). Install the agent with its own installer, then press Detect again.
+
+### Agent panel
+
+Click the agent chip in the chat header. The panel opens over the chat column with a shadow and a dimmed backdrop, sized like the column. It has a search field (name or id), and these sections:
+
+* **Detected**: agents found on your `PATH`, with the version and path. Click one to use it for this chat.
+* **Enable via npx**: agents that start through `npx` (Pi, Qwen Code, Kilo, Cline, Auggie, Copilot CLI, Qoder, CodeBuddy and the Claude Code and Codex ACP adapters). Each row has an `Enable` chip. The section says that it runs code fetched by npx.
+* **Not found**: registry agents that are not on this computer, folded by default.
+* **API endpoints**: your endpoints, with an `Add` action that opens Settings.
+* **Custom**: `Add custom agent` opens Settings.
+
+Each row has a status chip: `Ready`, `Enable`, `Not found`, `Wrong program`, `No key` (an endpoint without a key) or `Set up` (an endpoint without a URL or model). Arrow keys move through the rows, Enter picks one, Escape closes the panel.
+
+Settings → Chat has the same list, so an agent can also be hidden from the panel there (the `Show in the chat agent picker` switch on its row).
+
+### Setup card
+
+A chat with no backend chosen shows one card, "Connect an agent". It lists the agents detected on this computer, up to four, with `Show all agents` for the rest. Below them are `Add an API endpoint` and `Add custom agent`. The card never lists install steps.
+
+### Sign-in
+
+When an agent says it needs you to sign in (ACP's "Authentication required" and similar messages), the failed turn shows "<Agent> needs you to sign in" with the command from the agent's docs, then Retry. For Cursor that is `cursor-agent login`, for OpenCode `opencode auth login`, for Codex `codex login`, for Claude Code's ACP adapter `claude /login`. For agents without a known command the card says to sign in with the agent's own app and retry. Chat does not sign in for you.
+
+### Settings → Chat
+
+The page scrolls and keeps one grid for its labels. Its sections:
+
+* **Agents**: one row per agent, with its status, version and path. A details disclosure holds the **Path override** (for a binary that is not on `PATH`, or a specific install; empty means the first match on the merged `PATH`), the **Arguments override** (replaces the registry's ACP arguments, for example `--acp --debug`), and for npx agents the **Enable** button. The **Show in the chat agent picker** switch hides an agent from the panel. Custom agents have Name, Command and Arguments fields and a Remove button. `Detect again` re-runs detection.
+* **API endpoints**: add, edit and remove endpoints (name, format, base URL, model) and set the default one. Each has a key field with Save and Remove. Keys are stored in the macOS Keychain, Windows Credential Manager or the Linux Secret Service, under the service name `PaperCraft` and the user `api-key:<base URL>`. An older single key (`anthropic-api-key`) is still read for `api.anthropic.com` and moves to the new entry the next time you save it. Removing a key makes that endpoint stop until a key is saved again (for `api.anthropic.com`; other endpoints work without one).
+* **Defaults for new chats**: the backend, the endpoint, and the effort for `api.anthropic.com`.
+
+Settings from before endpoints existed (`api_model`) move into the default endpoint on first load. The `claude_path` and `codex_path` settings from earlier versions still win for their agent until you save the Agents list. These defaults, the agent settings and the endpoint list (never the keys) are saved in `chat_settings.json` in your config folder (`~/Library/Application Support/papercraft/` on macOS). They are not part of any project.
+
+## The thread
+
+The header has the chat title (rename), the chat list (new chat, switch, delete), the agent chip (for example `Claude Code · Opus 5.5`) and the context meter. The meter shows the tokens in the context at the last model call against a 200k window, and turns amber past 75%. It is hidden for Codex, which reports no per-call usage.
+
+Replies are markdown: paragraphs, lists, code blocks with a copy button, inline code and links. While a turn runs, the reply streams in.
+
+* **Thinking**: when the backend reports reasoning, a row shows "Thinking…" while it runs and collapses to a summary when it ends. Expand it to read the text.
+* **Tool cards**: one card per tool call with the verb and target (for example "Drawing layout · Card"), a spinner while it runs, and a failed state with the error. Args and result are collapsible. `get_screenshot` results show a thumbnail.
+* **Step groups**: consecutive tool calls in one reply fold into one line ("Built the card · 5 steps") that expands to the cards.
+* **Plan**: when the agent keeps a todo list (Claude Code's `TodoWrite`, or an ACP plan), the latest list is pinned above the composer with a "done of total" count.
+* **Approval**: on the API backend and for ACP agents, the destructive tools (`delete_pages`, `disable_library`, `import_design_system`, and `delete_nodes` on more than 20 layers) wait for Approve or Deny before they run. Deny returns an error to the model, which can then carry on. For ACP agents, any non-PaperCraft tool the agent asks for shows the same card. The Claude Code and Codex CLIs do not show this card. They use the CLI's own permission rules, and in non-interactive mode a tool that needs permission is denied. The papercraft tools are pre-allowed on both CLIs.
+* **Checkpoint**: when an agent run starts, the thread shows "Checkpoint · before run N". "Restore to here" reverts that run and every run after it, through the same revert as the Agent view.
+* **Run card**: when a run ends, "Agent finished, N changes" with Review, Revert and Accept. These are the same actions as the run review on the canvas. The card names the client that made the run ("Chat", "Claude Code · 2") and refreshes after an undo.
+* **Progress**: while a run is open, the step group and the Working pill count calls and touched layers ("Styling · 212 calls · 1,340 changes"). The pill clears when the turn ends.
+* **Errors**: a failed turn shows a red row with Retry. A sign-in problem shows the sign-in card (see Setup).
+* **Canvas follow**: when a tool call targets a node, the canvas pans to it, unless you moved the camera in the last 10 seconds.
+* **Agent presence**: after each agent call, the layers it pointed at or changed get an accent outline that fades over 3 seconds, and the newest carries a label with the verb and the client ("Styling · Claude Code"). This works for chat turns and for any MCP client. When the agent works on another page, a chip "Agent on page X →" switches to it.
+
+## Design-system context
+
+Every turn carries a summary of the project's design system, so the agent reuses what exists instead of drawing look-alikes:
+
+* variables by collection and group with their modes (colors as `name=#light/#dark`), tokens as scales;
+* main components on every page and in enabled libraries, as `componentKey · name · w×h · uses`, most used first;
+* enabled libraries and their update status, and the page's annotation template;
+* a reuse rule: place components with `create_instance` / `swap_instance`, colors as `var(--…)`, spacing on tokens.
+
+The summary is capped at about 1,500 tokens. A large system keeps its most used components and collapses variable groups to counts, with a pointer to `get_components` / `get_variables` for the rest. It is rebuilt only when the design system changes. The API backends get it as a separate system block (cached on `api.anthropic.com`); CLI and ACP agents get it in their first prompt, and again as `[Design system changed] …` on the next message after a change. The context meter includes it. Turn it off in Settings → Chat → **Send design-system summary**.
+
+`lint_design` has a matching rule, `not-an-instance`: a frame built by hand that matches a component (same structure, size within 4 px, same fill, radius and stroke) is flagged with the component to use.
+
+## Pointing at the canvas
+
+* **Pick**: the Pick chip next to `@ Selection` turns the canvas into a picker without changing your selection. Click a layer to add it, or Shift+drag an area; Esc cancels. Each pick types `@Name` at the composer cursor and adds a chip.
+* **⌥-click**: in Chat mode, ⌥-click a layer on the canvas to add it the same way.
+* **Area chips** are sent as `[Area] page P, rect x,y,w,h, contains: <ids…>` (the top layers wholly inside the area, up to 40).
+* **Crops**: layer, area and `@ Selection` chips carry an image of that part of the page with its notes drawn (1024 px max). The API backend gets it as an image block; CLI and ACP agents get a file under `.papercraft-chat-tmp/`.
+* **Ask (⌘K)**: with a selection, ⌘K opens a prompt box anchored above it. Enter sends to the chat with the selection chip and its crop, and the reply streams in the chat column without leaving Design mode. With nothing selected, ⌘K opens the command palette (also ⌘⇧/).
+
+## Actions on a selection
+
+The **Actions** menu opens from the canvas right-click menu, from the Actions chip in the composer and from the command palette ("Actions: …"). It works in Design and Chat modes.
+
+Instant actions run in the app with no model. Each one is a single undo step and its own run (client "Actions"), and a toast reports what it did with Review and Revert:
+
+* **Fix lint here**: `lint_design {fix: true}` on the selection.
+* **Bind to tokens**: binds hard-coded colors to the nearest variable (within 12 RGB) and gaps, padding and radii to the nearest spacing or radius token (within 2 px). Values with no close match are listed.
+* **Use components**: replaces each `not-an-instance` hit with an instance of its component in the same place, keeping the texts.
+* **Rename layers**: names default layers (`Frame 12`, `Text`) from their text or role.
+* **Annotate**: opens the annotation popover.
+
+Agent actions send a prompt with a selection chip to the chat and switch to Chat mode: **Optimize** (tighten layout and spacing to the token scale, fix contrast, keep the content, prefer components), **Make consistent with the design system**, **Write states** (empty, loading, error), **Variations ×3** and **Annotate with AI**.
+
+**Send open notes to chat**, in the inspector's Annotations section for a top-level frame, sends the frame's open feedback and its `todo` / `question` notes as one prompt with a chip.
+
+## Composer and attachments
+
+Type in the composer, ⏎ sends and ⇧⏎ adds a line. The empty state offers suggestions built from the project, such as "Design a sign-in screen using this project's variables" or "Lint this page and fix warnings".
+
+* **Selection**: the `@ Selection` chip adds the current selection to the message as a chip (also ⌘L). Each click adds another chip, labelled with the layer name or `<first> · N layers`; an identical selection is added once, and each chip is removed on its own. Every chip is sent as a short line with the layer name and node ids.
+* **Start failures**: if a turn cannot start (agent missing, bad path), an error row with Retry shows in the thread and your text stays in the composer.
+* **Images**: the image button opens a file picker. You can also paste a clipboard image or drop image files on the column (PNG, JPEG, GIF, WebP).
+
+For the API backend, images are sent as image blocks, so the model sees them. For the CLIs and ACP agents, each image is saved under `.papercraft-chat-tmp/` in the project and its path is added to the prompt for the agent to read.
+
+While a turn runs, the send button becomes **Stop**. Stop asks the backend to interrupt: the CLIs get an interrupt, or SIGINT, then a kill after 3 seconds; ACP agents get `session/cancel`, then a kill if they do not exit. Every backend ends within 3 seconds. The thread shows a muted "Stopped" line, not an error. Tools that already ran stay applied, and the partial run can be reviewed or reverted like any other.
+
+## Storage
+
+A chat is one file in the project: `chats/<id>.json`, holding the title, the backend (kind, model, effort, CLI or ACP session id, agent) and the messages with their tool calls, usage and run ids. The API backend also keeps `chats/<id>.api.json`, the raw messages array (Messages format with thinking blocks, or Chat Completions format, whichever the endpoint speaks), so a follow-up replays exactly. The chat records its endpoint id. Deleting a chat asks first and removes both files, and its saved images.
+
+Projects without a `chats/` folder load unchanged. The newest chat opens when you enter Chat mode.
+
+## Privacy
+
+PaperCraft never writes an API key into a project file, a chat or a log. The key lives in the OS credential store. The CLIs and ACP agents run with your own logins and do not get the API keys from the environment: `ANTHROPIC_API_KEY`, `ANTHROPIC_AUTH_TOKEN`, `OPENAI_API_KEY` and `CODEX_API_KEY` are removed from their environment, so Claude Code and Codex bill your account, not a key you set for PaperCraft. The MCP server listens on loopback only, as it does for any other client.
+
+Prompts, project content and tool results go to whichever backend you chose: the CLI's or agent's model service, or the base URL of the endpoint you picked. Nothing goes to any other service. An npx agent downloads its package from npm the first time it runs. If a server echoes your key in an error message, the app hides it before showing the message.
+
+## Limits
+
+* One turn per project at a time. Sending while a turn runs is refused with "A turn is already running"; use Stop first. Switching to another project stops a running turn.
+* The web build has no Chat mode.
+* While the agent works, the canvas shows fading outlines of the layers it touches; the full change review (added, changed, removed) comes after the turn, when the run is reviewed.
+* Variations ×3 is a prompt for now: the agent makes the variants; there is no side-by-side Keep tag yet.
+* Over the ACP stdio bridge the chat id does not reach the server, so those runs show under the agent's client name and close after 30 seconds idle instead of at turn end.
+* The API backend stops after 40 tool rounds in one message and says so.
+* Codex reports no per-call usage, so the context meter is hidden for it.
+* Agents need to be installed and signed in with their own tools. Chat does not install them or sign them in for you.
+* ACP terminal and file-system requests from an agent are answered as not supported. Agents use their own file tools.

 # Design systems in PaperCraft

-A PaperCraft project can hold a small design system: color variables, components with instances, and icon sets. Today these are built and managed through the tools (MCP or `papercraft-cli`); the editor shows the results but has no panel for them yet (see [ROADMAP.md](../ROADMAP.md)).
+A PaperCraft project can hold a design system: collections of typed variables with modes, components usable from any page, icon sets, and libraries that other projects can enable. The editor has a Variables modal, a Libraries modal and an Assets view for them (see [ROADMAP.md](../ROADMAP.md)); the same things are available through the tools (MCP or `papercraft-cli`).

 ## Variables

-Named colors per project. Define them once, use them as `var(--name)`:
+Variables live in **collections**. A collection has one or more **modes** (`Light`, `Dark`) and each variable has one value per mode. The project stores them in `design.json` next to `project.json`; every page keeps a derived copy that the renderer, lint and exports read, rebuilt on every change. A change from the UI or a tool updates every page in one undo step per page.

 ```sh
 papercraft-cli call set_variables '{"variables":{"surface":"#313244","accent":"#cba6f7","on-accent":"#11111b"}}'
+papercraft-cli call set_variables '{"collection":"Spacing","type":"number","variables":{"space/md":16,"space/lg":{"value":24}}}'
+papercraft-cli call set_variables '{"variables":{"accent-hover":{"alias":"accent"}}}'
 ```

-* Use `var(--name)` in `write_html`, `update_styles` and `create_artboard` for `background`, `backgroundColor` and `color`. The fill stays linked and the link is saved in the file.
-* Calling `set_variables` again with a new value moves every linked fill, on every page, in one undo step.
-* **Modes.** `set_variables {"mode":"Dark", ...}` stores one set of values for a mode; define another mode the same way. The first mode you define is active. `set_variable_mode {"mode":"Light"}` switches the whole project.
-* `get_variables` lists the variables and modes. With `"format":"css"` it returns a `:root { --name: #hex }` block, with `"json"` a design-tokens object (`{"accent":{"$type":"color","$value":"#cba6f7"}}`).
-* **Limits.** Colors only. Fills and text color follow variables; strokes and gradients get the resolved color at write time and do not follow later changes. No spacing, radius or font-size variables yet.
+* **Types.** `color`, `number`, `string`, `boolean`. Numbers have no unit and bind as px. Strings are substituted as text (a font family, a shadow). Booleans bind to layer visibility. An alias points at a variable of the same type, in any collection or enabled library, and resolves per mode. A cycle is refused.
+* **Groups.** A name is split on `/`: `color/brand/primary` sits in the group `color/brand`. Renaming a group in the Variables modal renames every variable under it and the bindings follow.
+* **CSS names.** The name's segments joined with `-`, sanitized: `--color-brand-primary`. Use `var(--color-brand-primary)` in `write_html`, `update_styles` and `create_artboard` for `background`, `backgroundColor` and `color`. Two variables with the same CSS name across the collections of a project (library ones included) are refused when written.
+* **Modes.** The active mode is chosen per page and per collection (Design tab), not per project; a new page inherits the active page's choice. `set_variables {"mode":"Dark", ...}` stores values for a mode, and the first mode you define is active. `set_variable_mode {"mode":"Light"}` switches the whole project. `create_collection {"name":"Brand","modes":["Light","Dark"]}` makes a collection with its modes up front.
+* **Reading and exporting.** `get_variables` returns the collections (id, groups, type, value per mode, aliases, description, hidden), `pageModes`, and the older `variables` and `tokens` maps. With `"format":"css"` it returns a `:root { --name: #hex }` block plus `[data-theme]` rules for modes, with `"json"` a design-tokens object where groups nest on `/` and aliases are `{group.name}`, with `"tailwind"` an `@theme` block. Copy CSS, JSON and Tailwind are in the Variables modal too.
+* **Deleting.** `delete_variables {"names":[...]}` refuses a variable that another one aliases and names the dependents; `"force":true` detaches them to the resolved value first. In the UI the same asks for confirmation. A removal affects every page.
+* **Hidden.** A variable marked `hidden` stays in the file and is left out of published libraries.

 Naming that works: roles, not hues (`surface`, `text-muted`, `accent`, `on-accent`, `danger`), so a mode can change the value without changing the meaning.

+### Bindings
+
+A fill that was written with `var(--name)` stays linked. Other fields bind with `bind_variable {"nodeIds":[...],"field":"gap","variable":"space/md"}` or with the variable button next to the field in the inspector. A bound field shows the variable as a chip with a detach button; detaching keeps the current value. `variable` may be the name or the CSS name; `null` detaches.
+
+| Field | Type | Applies to |
+|---|---|---|
+| `stroke`, `text-color` | color | stroke color, text color |
+| `width`, `height` | number | size in px |
+| `gap` | number | auto-layout gap |
+| `padding`, `padding-top`, `padding-right`, `padding-bottom`, `padding-left` | number | auto-layout padding (`padding` sets all four) |
+| `radius` | number | corner radius |
+| `font-size` | number | text size |
+| `line-height` | number | below 4 it is a multiplier (`1.5`), from 4 up it is px |
+| `opacity` | number | 0 to 1, values outside are clamped |
+| `visible` | boolean | layer visibility |
+
+A bound field is applied again when the variable, an alias target or the page's mode changes. Instances take bindings from their main; changing a bound field on an instance is an override for that instance only. Gradients cannot be bound yet.
+
+### Migration
+
+Projects made before collections open as project version 2: the first page's colors and modes become the collection `Colors`, its tokens become `Tokens` (a `16px` value becomes a number, anything else, including a unitless `1.5`, stays a string). CSS names do not change, so existing fill bindings keep working. PaperCraft 0.4.0 does not know `design.json`, so it refuses a migrated project with "made by a newer PaperCraft" instead of writing pages that would drift from it. Update before opening such a project on another machine.
+
+### Variables modal
+
+Open it from the Design tab ("Open variables"), the command palette (`Variables…`) or ⌘⌥⇧V. Collections of this file are on the left, then each enabled library (read-only), each with its group tree. The table has one row per variable in the selected group and one column per mode; cells edit in place (swatch and hex, number, text, toggle) and an alias picker links to another variable. Add a variable (choose its type), a mode or a collection from the header; rename, delete, search and a details pane (description, hidden, CSS name, how many layers use it) are there too.

+Any project can publish itself as a library, and other projects can enable it. This is a published snapshot, as in Figma, not a live link.
+
+* **Publish.** Libraries modal, tab "This file", or `publish_library`. It writes `library.json` in the project folder with a version counter, the non-hidden variables, and every main component whose name does not start with `_` or `.`, each with its layers and a 256px preview. Before publishing the modal shows what changed since the last publish ("3 variables changed, 1 component added"); the tool returns the same list.
+* **Enable.** Every project in the store with a `library.json` is available (projects synced from other devices through the relay show up too). `enable_library {"libraryId":...}` or the toggle in the Libraries modal copies the snapshot into the project (`libraries/<id>.json`). Its variables show read-only in the Variables modal and can be bound and aliased; its components show in Assets and are placed with `create_instance {"componentKey":...}`. Enabling is refused if a CSS name already exists in the project.
+* **Updates.** When the published version is newer than the copy, the Libraries modal tab "Updates" and a dot on the Assets tab say so, and `list_libraries` reports `updateAvailable`. The review lists changed variables and components. `update_library` (or Update in the modal) replaces the snapshot, rebuilds every page and re-syncs the library's instances; instance overrides are kept. Updates are never applied by themselves.
+* **Missing source.** If the library's project is deleted or not in the store, the copy keeps working. The modal shows "Source not found" and `list_libraries` shows `sourceFound: false`.
+* **Disable.** `disable_library` or the toggle (after a confirm when it is in use) stops using a library: bindings to its variables are detached and keep the resolved value, local variables that aliased it keep the resolved value, its instances become plain frames, and its variables and components leave the project. One undo step per page.

 Lint passes are necessary, not sufficient: contrast and grids say nothing about composition. The screenshot is the real test.

+## 2b. Big jobs and several agents on one project
+
+Lessons from redesigning a 3-page, 130-screen project with up to six agents at once:
+
+* **Split by section, not by page.** Give each agent named sections (frame ids) and forbid the rest. New sections go below the current lowest one; re-read positions right before creating, since another agent may have just added one.
+* **Section layout**: a section frame holds a title and rows of screen slots (a route label above a fixed-size screen). Keep 640 px between screens and rows and 1600 px between sections, so notes fit beside screens. Stack sections in one column.
+* **Recreate, then delete.** Build the new screen next to the old one, finish it, then delete the old one, and record the deleted ids and names in the report. A cleanup agent once deleted buttons and lost icons by editing in place.
+* **Reuse the design system across pages**: `create_instance` / `swap_instance` / `<x-paper-instance>` take a main from any page and stay linked. Never `import_components` to use a component: that copies mains onto the page, and instances made from the copies stop following the design system. `lint_design` flags hand-made look-alikes as `not-an-instance` (with the component key to use).
+* **QA pass after a build** (screen by screen at scale 1, one call at a time): text layers with stale fixed widths clip labels ("In prog", "New sess"): set `width: fit-content`. Sidebars and panels fixed at 900 px stop short on taller screens: make them fill the height and let the screen hug with a 900 px minimum. Tags and chips overflowing their box, cards overlapping buttons, footers not pinned, leftover `Text` / `Frame` names, gendered copy about people whose gender is unknown (use their name or neutral wording).
+* **Report per agent** in `specs/<feature>/<agent>-report.md`: what changed (ids), why (playbook rule ids from `playbook search`), open questions. Unknown product facts are written as questions for the team, never invented.
+
+## 2c. Annotations
+
+* Read the page's template first (`get_annotation_template {pageId}`), then one batched `annotate {pageId, notes:[{node, text, type}]}` per section, then `annotate {pageId, frame: <section id>, tidy: true}` (returns `{tidied: n}`; 0 means already placed).
+* Content: the first line is the complete rule in 60 characters or fewer; the body is condition → outcome with values as `Field: value` lines; attach to the exact element, not the screen; few high-value notes; unknowns as `? (team)`. Rules: `playbook rule ANN`.
+* Check placement with `get_screenshot {nodeId: <screen slot>, annotations: true, scale: 0.5}`; plain screenshots do not show notes. Cards must sit beside their target off any screen, lines must not cross other screens. Below 60% zoom the canvas shows notes as badges.

 ## 6. Known limits (design around them)

 * **Font is Inter only**, regular and bold plus italic. No other families, no weights between. Build hierarchy from size, weight, color and space.
-* **Variables are colors only**, for fills and text color. Strokes and gradients keep fixed colors. Spacing, radius and type sizes are plain numbers: keep them on the scale by discipline and `lint_design`.
+* **Variables** are typed (`color`, `number`, `string`, `boolean`), live in collections with modes, group with `/` (`space/md`, `color/brand/primary`) and can alias each other. Colors work as `var(--name)` on fills and text; every other field binds with `bind_variable` (stroke, text-color, width, height, gap, padding, radius, font-size, line-height, opacity, visible). Numbers bind as px; line-height below 4 is a multiplier. Gradients keep fixed colors.
 * **No margin, grid or tables; no shadows, filters or transforms** (reported under `ignoredStyles`). Fake elevation with a border or a lighter surface.
 * **No rotation.** Nodes are axis-aligned.
-* **Components and their instances live on one page.** Put shared components on the page where they are used, or duplicate the component per page.
-* **No variants or properties**: one component per variant (`Button / Primary`, `Button / Secondary`). No swap or detach tool.
+* **Components work across pages**: `create_instance` takes a main from any page or enabled library (`componentId` or `componentKey` from `get_components`) and follows later edits. To share with other projects, `publish_library` there and `enable_library` here; `update_library` pulls a newer publish.
+* **No variants or properties**: one component per variant (`Button / Primary`, `Button / Secondary`). `swap_instance` and `detach_instance` exist.
 * **Remote images are not fetched.** Use a local path or `data:` URI.
 * **One project open at a time**; moving layers between pages is not supported.
 * **Text boxes with fixed widths can wrap earlier than in a browser.** Check headlines in the screenshot and widen.

 * **Text inside nested frames**: `set_text_content` needs the Text node id. Walk `get_children` down from the instance; instances copy the main's structure (`Meta > Label`, not a flat list).
 * **No icon-colour follow for stroke sets** (Lucide, Tabler): the colour is frozen at write time, so a mode switch (Mocha to Latte) leaves icons as they were. Use a fill set (Phosphor, Material) when a design must switch modes.
 * **Pages**: `create_page`, `rename_pages`, `delete_pages` (needs `confirm: true` when the page has layers; the last page stays). `move_nodes` accepts `toPageId` to copy between pages.
-* **`get_screenshot` of `root` on a wide page** is scaled to fit and unreadable. Screenshot one artboard at a time. Hoisted components are not inside an artboard screenshot.

 * Build every repeated thing once: `create_component`, then `create_instance` or `<x-paper-instance>`. Never paste markup twice. A screen is mostly instances plus layout frames.
 * No raw colours, radii, spacing or shadows in `write_html`: `var(--token)` only. Changing a token then updates every page, and `get_design_spec` reports token names, which is what code needs.
-* Reuse across pages with `import_components` (instances stay linked) or `<x-paper-clone node-id="page:id">`. Do not rebuild a component per page.
+* Reuse across pages with `create_instance {componentKey}` or `<x-paper-instance component="Name"/>` in `write_html`: a main on any page (or an enabled library, for `create_instance`) works directly and the instance stays linked to it. Do not `import_components` for that (it makes detached copies; it is for moving a design system). Do not rebuild a component per page.
 * One design system per brand: `export_design_system` writes an OpenDesign package (variables, modes, tokens); `import_design_system` loads it into another project. That is the sync path between files and apps.
 * Write one visual group per `write_html` (a header, a row), with `layer-name` on every box. Fewer, larger writes cost fewer round trips; groups that are too big make one bad style hard to find.

In auto-layout parents this changes the visual order; in free parents it changes stacking and keeps the world position.

 ### `create_shape`

 Create a whiteboard element: rectangle, ellipse, diamond, triangle, polygon, star, line, arrow, sticky (sticky note with text) or text. Coordinates are world units, or relative to parentId when given. Lines and arrows take `points` ([[x,y],...], at least two) and arrows may bind to layers with startNodeId/endNodeId (the arrow then follows them). `styles` takes the same CSS as update_styles plus the hand-drawn keys sketch, roughness (0 architect, 1 artist, 2 cartoonist), fillStyle (hachure, cross-hatch, solid, zigzag, dots), strokeStyle (solid, dashed, dotted). Arrows also take route (straight, curved, elbow) and startHead/endHead (none, arrow, triangle, dot, bar, diamond).

+# Annotations: notes with leader lines that explain a design
+
+## Why (user request, 2026-10-21)
+
+Teams annotate designs in Figma with callouts and arrows that explain what each part does: business rules, behaviour, states, data sources, edge cases. They are toggled on for review and handoff and off for presenting. PaperCraft has comments (threads, open/resolved) but nothing that documents a design in place.
+
+## Model
+
+* An **annotation** belongs to a page: `{ id, target: NodeId (or a point), anchor: side or offset on the target, label: short title, body: markdown text, category, number, position: where the note sits on the canvas, author: user | agent, created }`. Stored in the page file under `annotations` (serde default; old pages load unchanged).
+* **Categories** are project-level, editable: default `Business rule`, `Behaviour`, `Content`, `Data`, `Accessibility`, `Dev note`, each with a colour (theme palette) and icon.
+* Annotations survive moves and resizes of the target (anchor is relative); deleting the target keeps the annotation detached with a warning badge.
+
+## Classification drives the look (user, 2026-10-21)
+
+* The **category is the only styling input**. Icon, colour, badge shape and default label prefix come from the category; an annotation stores no icon or colour of its own. Changing a category's colour or icon restyles every note in it.
+* Categories carry a short **type key** used everywhere (`rule`, `behaviour`, `content`, `data`, `a11y`, `dev`); custom categories get a key too.
+* **Hiding information**, three levels, all undo-free view state (not saved in the design):
+  * per note: collapse to its number badge only (click the badge to expand);
+  * per category: show/hide from the category filter;
+  * global (⌘⇧A cycles; ⇧A is Add auto layout): full notes → badges only → hidden.
+  * Exports and Present mode use "hidden" unless chosen otherwise.
+
+## Templates (user, 2026-10-21)
+
+People annotate differently per project and even per page (a product spec, a dev handoff, an accessibility review). A **template** says which kinds of notes are wanted and what each should contain.
+
+* `AnnotationTemplate { id, name, categories: [ { key, enabled, prompt: short guidance for what this note should say, fields: [name] (optional structured lines, e.g. "Applies when", "Owner") } ], display: full | badges }`.
+* Stored in `design.json` (project-level list); the **project default** is one template, and a **page can override** it (`page.annotation_template`, serde default). New categories added in a template become available project-wide.
+* **Built-in templates** (editable copies, not locked): `Product spec` (rule, behaviour, content, data), `Dev handoff` (behaviour, data, dev, a11y), `Accessibility review` (a11y with fields "Issue", "WCAG", "Fix"), `Content review` (content with "Tone", "Max length"), `Minimal` (rule only).
+* **UI**: the Annotations side view header has a template picker (project default or this page) and a "Customize…" modal: toggle categories, edit name/colour/icon/key, edit each category's guidance and fields, duplicate/reset a template. The Annotate popover only offers the template's enabled categories, and shows the fields as labelled lines.
+* **Ask AI**: an "Annotate with AI" button in the side view (and a chat suggestion "Annotate this page") sends a prompt to the chat: annotate the selected frame or the page using the active template. The agent reads the template with one cheap call.
+* MCP: `get_annotation_template {pageId?}` returns compact `[[key, guidance, fields]]` for the enabled categories (a few hundred tokens); `annotate` rejects types the page's template disables (error lists the allowed keys) and accepts `fields` as `"Name: value"` lines inside `text`. `set_annotation_template {pageId?, template}` switches it.
+
+## Cheap for agents
+
+* One tool call can add many notes: `annotate {notes: [{node, text, type}]}` where `node` is a node id or a layer name on the active page, `text` is the note (first line becomes the label, the rest the body), `type` is the category key (default `rule`). No positions, icons or colours: placement is automatic (beside the target, outside its frame, stacked without overlap).
+* `get_annotations` returns compact rows `[n, node, type, text]`, not full objects; `{full: true}` for everything.
+* `update_annotation` / `delete_annotations` take ids or numbers ("frame Sign in #3").
+* The tool description stays under ~60 words.
+
+## Canvas
+
+* A note is a small card (number badge, label, first lines of the body) connected to its target by a **leader line**: elbow or straight, ending in a dot or arrow on the target's anchor, plus a thin outline around the target while hovered.
+* Notes are draggable; the line re-routes (reuse the connector router, `src/connector.rs`).
+* **Toggle**: View → Annotations (⌘⇧A) shows or hides all; a filter per category; never drawn in Present mode or exports (notes live only in the editor overlay; an export option to include them is a later item).
+* Numbering is per frame, in reading order, so a frame reads "1, 2, 3…".
+
+## UI
+
+* **Annotate tool** (N; A is the Frame tool): click a layer, type the note; or select layers → right-click → Annotate.
+* **Annotations side view**: list per frame with number, category chip, label; click to select and zoom; filter by category; edit inline.
+* **Inspector**: an Annotations section for the selected layer.
+
+## Agents and handoff
+
+* MCP: `annotate` (batch, see "Cheap for agents"), `get_annotations`, `update_annotation`, `delete_annotations`; classified in `edits_doc`.
+* `get_design_spec` and `get_jsx` include annotations as comments (`// 1 Business rule: …`), so code generated from a frame carries the rules.
+* Chat: the `@ Selection` context includes the selected layers' annotations; the agent can be asked to "annotate this screen".
+
+## Mock-ups
+
+`PaperCraft` design file, page `Annotations`: `Canvas / Annotated frame` (several categories, leader lines, numbering), `Canvas / Annotations hidden`, `Panel / Annotations` (344x1440), `Inspector / Annotation` (344x1440), `Popover / New annotation`.
+
+## Acceptance
+
+* Add, edit, move, hide/show, filter, delete annotations; undo for each.
+* Moving or resizing a target keeps the leader line attached; deleting it detaches the note with a badge.
+* Old projects load unchanged; page files without `annotations` stay byte-identical on save.
+* Exports and Present mode never include annotations.
+* MCP tools round trip; `get_design_spec` includes them.
+* Screenshot check against the mock-ups; tests for model, anchoring, numbering, serialization, MCP.

+# Chat agents: any agent, found reliably, and a picker that scales
+
+## Why (user report, 2026-10-21)
+
+* Claude Code and Codex show "Not found on PATH" although both are installed in `~/.local/bin`. Root cause: an app opened from the Dock or Finder gets the minimal macOS PATH (`/usr/bin:/bin:/usr/sbin:/sbin`); `launchctl getenv PATH` is empty. The user's login shell also finds `pi`, `opencode`, `gemini`, `goose` (`/opt/homebrew/bin`) and `cursor-agent` (`~/.local/bin`).
+* The setup state offers `npm install -g …` as the way to install agents. Claude Code and Codex have their own installers; PaperCraft should not tell people how to install agents at all.
+* Only two agents are supported; the user wants every popular agent, generically.
+* The agent picker popup has no shadow and overlaps the setup card; the Settings → Chat page has broken spacing, padding and height (fields not aligned, the page bottom cut off).
+* Sending a message did nothing: no `chats/` folder was created, no error was shown.
+* The composer allows one `@ Selection` chip; the user wants several.
+
+## Scope
+
+1. **Find agents like the shell does.** At startup (native, off the UI thread), resolve the login shell PATH once: `$SHELL -l -c 'printf %s "$PATH"'` with a 3 s timeout; merge with the process PATH and common folders (`~/.local/bin`, `/opt/homebrew/bin`, `/usr/local/bin`, `~/.cargo/bin`, `~/.bun/bin`, `~/.npm-global/bin`, Volta and nvm current bins). Use it for agent detection and for spawning agents (set `PATH` on the child). A path override in Settings still wins.
+2. **ACP backend** (`src/chat/acp.rs`): a generic Agent Client Protocol client (JSON-RPC 2.0 over the agent's stdio): `initialize`, `session/new` with `cwd` = project folder and `mcpServers` = PaperCraft's server (HTTP entry when the agent advertises `mcpCapabilities.http`, else a stdio entry running the bundled `papercraft-mcp` bridge with `PAPERCRAFT_MCP_PORT`), `session/prompt` with text (and image) content blocks, streaming `session/update` notifications mapped to our `Event`s (agent message chunks → Text, thought chunks → Thinking, tool_call / tool_call_update → ToolStart/ToolEnd, plan → Plan items), `session/cancel` for Stop, `session/request_permission` answered from our approval flow (papercraft tools allowed; destructive ones and any non-papercraft tool ask the user), `session/load` to resume when supported. The PaperCraft skill text goes in as the first prompt's leading context (ACP has no system prompt field).
+3. **Agent registry, as data** (`src/chat/agents.rs`): `{ id, name, detect: binary name, launch: command + args, kind: Native | Npx, docs_url }`. Native entries are found on the resolved PATH: Gemini CLI (`gemini --acp`), Cursor (`cursor-agent acp`), OpenCode (`opencode acp`), Goose (`goose acp`), Kimi (`kimi acp`), Devin (`devin acp`), Junie (`junie --acp=true`), Mistral Vibe (`vibe-acp`), Hermes (`hermes acp`), OpenHands (`openhands acp`), Stakpak (`stakpak acp`), VT Code (`vtcode acp`), Poolside (`pool acp`), Droid (`droid exec --output-format acp-daemon`). `npx`-launched entries (Qwen Code, Kilo, Cline, Auggie, Copilot CLI, Qoder, Codebuddy, Pi via `pi-acp`, Claude/Codex via their ACP adapters) are listed as available but off until the user enables them once, because enabling runs code fetched by `npx`. Claude Code and Codex keep their direct adapters (already proven) and are the default for them. Exact flags are verified against each installed agent's `--help` where installed; the rest keep the documented command and fail with the agent's own error.
+4. **Custom agent**: name + command + args (ACP over stdio). No provider lists beyond the registry.
+5. **No install instructions.** A missing agent shows "Not found" plus "Set path…" and a link to the agent's own docs (`docs_url`), nothing else.
+6. **Agent picker becomes a panel**, not a dropdown: opened from the agent chip, sized like the chat column (overlay with shadow and a backdrop), sections Detected, Enable (npx), API endpoints, Custom, a search field, and per row: icon, name, status chip (Ready, Needs enable, Not found, Signed out if detectable), version, path. Clicking a row selects it for this chat.
+7. **Settings → Chat** redesign with the same list (one row per agent with a details disclosure: path override, args override, enable), API endpoints as compact rows with an edit disclosure, consistent 16/24 px padding, labels aligned on one grid, the page scrolls instead of being cut off.
+8. **Setup state** in the chat column: one card "Connect an agent" listing detected agents to pick from (usually already some), plus "Add an API endpoint" and "Add custom agent"; no install commands.
+9. **Send bug**: reproduce, find the root cause, fix, and add a regression test; any start failure must show an error row in the thread (never a silent no-op) and keep the typed text.
+10. **Multiple selections**: each `@` adds a chip (selection at that moment, labelled by layer names); chips stack, can be removed one by one; all are sent as context lines with node ids.
+
+## Not in scope
+
+* Installing agents.
+* ACP terminal/file-system client methods beyond what PaperCraft needs (answer `fs/*` and `terminal/*` requests with "not supported" unless the agent requires them to work; most agents use their own file tools).
+
+## Acceptance
+
+* With the app launched from the Dock: Claude Code, Codex, Pi, OpenCode, Gemini, Goose and Cursor are detected on this machine.
+* A turn with Gemini CLI, OpenCode, Goose and Cursor (each installed here) creates an artboard through PaperCraft's tools via ACP; a Pi turn works after enabling `pi-acp`.
+* Stop cancels an ACP turn within 3 s.
+* Picker panel, Settings → Chat and the setup state match new mock-ups at 1440p and 1280x800; nothing clipped; shadows on overlays.
+* Sending a message always either starts a turn or shows an error row.
+* Three `@` chips can be added and removed independently.
+* Tests: PATH merge, registry detection with a fake PATH, ACP JSON-RPC handshake and update mapping against a fake agent process (recorded fixture), permission flow, cancel.

+# Gaps found while driving PaperCraft on the Interview project (2026-10-21..23)
+
+Observed by the orchestrating agent and its subagents through MCP / papercraft-cli on the user's Mac.
+
+## MCP / agent side
+1. `get_screenshot` never draws annotations, so no agent can verify note placement; every check needed a macOS screen capture of the live window.
+2. No tool to switch the page the user is viewing or to set the viewport (zoom / pan / fit a rect); `select_nodes {zoom:true}` only works on the active page and caps zoom at 1.0.
+3. Agents can't see what the user sees (viewport rect, zoom, selection on screen) except `get_selection`.
+4. `~/.local/bin/papercraft-cli` was stale (schema/list missing new tools) while `call` reached the app — CLI and app versions drift with no warning.
+5. Applying a code change to the running app needs quit + reinstall + reopen (no dev reload / no "restart and reopen project" path).
+6. Long batched edits (thousands of bindings, renames) run as many separate calls; no progress shown to the user in chat mode for CLI-driven agents beyond the "Working…" pill.
+7. Cleanup agents made destructive mistakes (deleted button copies, lost icons on LG buttons) with no per-agent review/diff of what changed; undo is global, not per agent run.
+8. Tidy/placement was blind to zoom-dependent card size (fixed), to screens inside sections (fixed), and lines detoured inside screens (fixed).
+9. `get_tree_summary` depth semantics surprised scripts (rows under "Screens" needed depth 3).
+
+## App / 0.6.2 follow-ups already noted
+- Run card stale after undo; lingering "Working" pill; Stop reported as error.
+- No-GPU panic should be a readable error; Wayland clipboard without DISPLAY.
+- Email truncation (no text-overflow ellipsis).
+- 13.7 s open once after install (first run, not reproduced).
+10. `find_nodes` text search returned nothing for strings that exist on the page (Candidate redesign agent, 2026-10-23) — reproduce and fix.
+11. `get_tree_summary` truncates long text to ~40 chars with no option for full text, so copy review across many screens is impossible without per-node reads.
+12. `annotate {tidy:true}` with no notes returns `[]`, which agents read as failure (fix in A1: `{tidied: n}`).
+13. When the app stops mid-run the CLI silently falls back to offline writes; several agents then write the same project files concurrently with no lock (lost-update risk). Also a CLI call during app start-up reports "app not running" and goes offline.

+# Chat ↔ canvas: research
+
+How canvas + AI products let a user act through chat and point at the canvas, and what PaperCraft already has. Researched 2026-10-23. Secondary sources (forums, reviews) are marked; treat their details as approximate.
+
+## 1. What PaperCraft does today (code)
+
+* **One path to the canvas: tool calls.** Every backend (Claude Code, Codex, ACP, API endpoints) edits only through the 69 MCP tools. CLI/ACP agents reach them over HTTP MCP (`src/mcp/server.rs`); API endpoints call `crate::mcp::exec` on the UI thread (`src/chat/tools.rs`, `ToolDispatch`). The user can't trigger anything in-process from chat except sending text.
+* **Context the agent gets:** `skills/papercraft/SKILL.md` (14 KB) plus the project name and folder (`ChatState::system_prompt`, `src/ui/chat.rs:602`). There is no design-system digest, no viewport and no screenshot of what the user sees.
+* **Pointing:** the `@ Selection` chip (⌘L), `add_selection` in `src/ui/chat.rs`. It sends `[Selection] <label> (<node ids>)` plus the annotations on those layers (`selection_notes`). It has no image, no region and no point. Annotations' "Annotate with AI" (`src/ui/annotations.rs:557`) is the one canvas-to-chat hand-off: it drafts a prompt, adds a chip and switches to Chat mode, but does not send.
+* **Showing agent work:** the activity pill (`agent_pill`, `AGENT_PILL_FRAME_MS`, `agent_verb` in `src/ui/mod.rs:310-360`) shows a verb only, with no location. Canvas follow (`follow`/`pan_to`, `src/ui/chat.rs:1056`) pans to the node in the call args, on the active page only. The review overlay (`review_overlay`, `src/ui/mod.rs:1929`) draws added/changed/removed outlines, but only after the run ends and is opened for review (docs/chat.md, Limits).
+* **Runs:** `src/runs.rs` has one global `Tracker`. A run is closed by a 30 s idle, `finish_working_on_nodes` or the end of a chat turn. Each run has auto-versions per page, plus `revert`, `revert_all` (checkpoint "Restore to here") and `revert_change` (one change). The chat has a Checkpoint row and a Run card (Review/Revert/Accept). MCP calls carry no client identity (`call_tool` ignores `RequestContext`), so parallel subagents land in one run (gap 7).
+* **Screenshots:** `get_screenshot` renders nodes with `io::png::render`. Annotations are an egui overlay (`src/ui/annotations_canvas.rs`), so they never appear (gap 1). `src/model/annotation_layout.rs` (new) already gives pure card sizes, placement and leader routing in world units.
+* **Camera tools:** `select_nodes {zoom}` works only on the active page and fits with a 1.0 zoom cap (`src/mcp/exec.rs:5266`). There is no page switch and no viewport read.
+* **Design-system data that already exists:** `get_variables` (vars, tokens, modes; css/json/tailwind), `get_components` (page mains with use counts plus `ed.library_docs` mains), `get_annotation_template`, `lint_design {fix}` with `lint::autofix` (rules: text-size, type-scale, spacing-grid, touch-target, layer-name, hard-coded-color), `get_design_spec`, `diff_frames`, `swap_instance`, `bind_variable`. There are no component variants in the model.
+* **Rendering stack:** custom `egui_winit` + `egui_wgpu` (`src/app.rs`, `src/render/frame.rs`), not eframe, so `ViewportCommand::Screenshot` is not handled. `render/gpu.rs` already has `start_readback` (texture to buffer).
+
+## 2. Products
+
+### tldraw: agent starter kit, Make Real, fairies
+* Agent context: the user message, the **selection, the viewport**, a screenshot of the agent's view, a simplified shape list in view, **off-screen shapes summarised as clusters (bounds + count)**, recent user actions, and lint warnings. The user can add shapes, **a point or an area** as extra context. ([starter kit](https://tldraw.dev/starter-kits/agent), [AI docs](https://tldraw.dev/docs/ai))
+* The agent **moves its own viewport** to look at parts of the canvas. Actions stream in and apply one at a time. Each action shows in chat with an icon and a one-line description. **Modes** (working, critique) limit the tool set per task. ([v4.4 release](https://tldraw.dev/releases/v4.4.0))
+* Make Real: select shapes, click one button, and the selection's screenshot goes to the model. You iterate by drawing on top of the result. ([talk summary](https://gitnation.com/contents/make-real-tldraws-accidental-ai-play))
+* Fairies (Dec 2025 experiment): agents shown as small characters on the canvas. **Where an agent is shows what it is working on**, and several run concurrently on shared space. ([talk](https://gitnation.com/contents/agents-on-the-canvas-with-tldraw), [tldraw offline](https://tldraw.dev/blog/tldraw-offline))
+* Works: viewport and region as first-class context, a cheap off-screen summary, visible presence.
+
+### Figma: AI, Make, MCP
+* Quick actions (⌘K): Rename layers (only default-named layers), Make prototype, Make designs. These are **one-click scoped actions on a selection**, with no chat. ([quick actions](https://help.figma.com/hc/en-us/articles/23570416033943-Use-quick-actions), [Figma AI](https://www.figma.com/blog/introducing-figma-ai/))
+* First Draft can't use your own design system; it uses Figma-built libraries. ([help](https://help.figma.com/hc/en-us/articles/23955143044247))
+* **Make kits**: components and styles bundled with **usage guidelines**, so the model learns *how* to use the system, not just what is in it. Attachments (PDF, CSV/JSON, SVG) ground prompts in real data. ([blog](https://www.figma.com/blog/introducing-make-kits-and-make-attachments/))
+* Best practices for AI to read a DS: semantic slash names, larger reusable blocks (cards, headers) over atoms, auto layout with sizing intent, full variant and property sets, variables for every color, space, radius and type, and a usage-examples page. ([help](https://help.figma.com/hc/en-us/articles/38978644498199-Best-practices-to-help-Figma-AI-understand-your-design-system))
+* Failure mode reported by users: Make "only recognises a random subset of components" and "created new ones that looked like my components". (forum, 2025: [1](https://forum.figma.com/suggest-a-feature-11/figma-make-not-using-my-library-components-42235/index1.html), [2](https://forum.figma.com/share-your-feedback-26/figma-make-library-support-42423)) The lesson: putting the library "in context" is not enough. Reuse must be checked.
+* Dev Mode MCP: `get_variable_defs` returns the variables used **in the selection**, Code Connect maps nodes to code components, and `create_design_system_rules` writes a rules file for agents. Selection-based prompting works only with the desktop server. ([guide](https://github.com/figma/mcp-server-guide))
+* Works: selection-scoped context, DS rules as a compact digest, one-click actions.
+
+### Cursor Design Mode (browser)
+* Click an element to target it. **Shift+drag selects an area.** You can draw circles or boxes over a **frozen frame** of the viewport, and voice is accepted. ⌘L adds to chat, ⌥+click adds without the comment step. The agent gets element identity (xpath, component, computed styles) **plus a screenshot**. You can queue several edits while agents run. ([docs](https://cursor.com/docs/agent/design-mode))
+* Agent checkpoints: a timeline in the chat, preview at a point, restore. Per-file Keep/Undo appears in the review panel. Reject bugs that deleted whole files show the risk of coarse undo. ([forum](https://forum.cursor.com/t/per-change-keep-undo-buttons-missing-after-agent-edits-only-undo-all-available/158983), [forum](https://forum.cursor.com/t/cursor-deletes-entire-file-when-changes-are-rejected/151760))
+* Pain points (forum): a new pick overwrote the previous one, and the chip always lands at the end of the prompt. ([1](https://forum.cursor.com/t/new-visual-editor-prevents-adding-multiple-elements-in-chat-box/145962), [2](https://forum.cursor.com/t/insert-browser-tab-element-selection-at-cursor-in-composer-not-always-at-end/167268))
+* Works: identity + pixels together, area selection, multiple chips.
+
+### v0 design mode / Lovable visual edits
+* v0: hover highlights and click selects. The **selected element shows as a badge in the prompt**, and the prompt is scoped to it. Direct panel edits are free; prompts cost tokens. A later version added annotations on elements **sent as one batched prompt**. ([v0 docs](https://v0.app/docs/design-mode), [changelog summary](https://www.createwith.com/tool/v0/updates/v0-launches-design-mode-with-visual-editing-and-layer-management))
+* Lovable: select one or more elements (⌘-click for multi), then describe the change. The selection is the context. ([docs](https://docs.lovable.dev/features/preview-toolbar))
+* Works: two lanes, deterministic edits for free and prompts for intent. Comments become a batch prompt.
+
+### Google Stitch
+* **Annotate**: draw a box around an element, type in a bubble, and only that element changes. You can also circle or write notes on the screen. **Variations**: select a screen and generate N (default 3) side by side, with a creativity range. "Create variant" keeps the original. ([review](https://designproject.io/blog/google-stitch-review/), [guide](https://tutorialsdojo.com/what-google-stitch-actually-does-and-where-it-falls-short/), secondary)
+* Works: on-canvas prompt bubble, variations as siblings on the canvas, never overwriting.
+
+### Canva Magic Edit
+* Brush the area, then prompt one change per pass. Canva advises against giving size in words; the brushed area carries it. ([help](https://www.canva.com/help/using-magic-edit/))
+* Works: the region carries the spatial intent, so the prompt stays short.
+
+### Miro Sidekicks, Framer, Excalidraw, Penpot
+* Miro: select clusters, then ask a task-specialised "Sidekick" (persona/mode) to transform them, for example into sticky notes. It has an MCP server for outside agents. ([TrustRadius](https://tr-web.dev.trustradius.com/products/miro/details), [MCP](https://miro.com/pl/ai/mcp/), secondary)
+* Framer Wireframer: prompt a layout, then keep iterating in chat or jump to the canvas. Workshop builds components that match the site's style. ([update](https://www.framer.com/updates/wireframer))
+* Excalidraw: AI is in the paid tier (text-to-diagram, wireframe-to-code). Community MCP servers give agents a live canvas. ([listing](https://www.stork.ai/de/excalidraw), [mcp_excalidraw](https://docsearch.algolia.com/mcp/docs/repo/yctimlin/mcp_excalidraw))
+* Penpot: experimenting with MCP for agents that read and edit design data. ([summary](https://mcpmarket.com/es/news/9fad1b76-0f9d-4411-b557-348e8f85888c), secondary)

+## 3. Patterns, ranked by value for PaperCraft
+
+| Pattern | Seen in | PaperCraft today | Gap |
+|---|---|---|---|
+| Selection as scoped context, with pixels | Cursor, v0, Lovable, Figma MCP | `@ Selection` ids + notes | no image, no region |
+| Area/lasso or point as context | Cursor, tldraw, Stitch, Canva | none | missing |
+| One-click scoped actions on selection | Figma ⌘K, Lovable panel | Annotate menu only | add Optimize, Bind tokens, Rename, Fix lint |
+| Deterministic lane vs model lane | v0, Lovable | `lint_design {fix}` exists, not in UI | expose without the LLM |
+| DS digest in context + reuse check | Figma Make kits, `create_design_system_rules` | only the skill text | add a digest and a reuse lint |
+| Agent viewport + presence | tldraw agent, fairies | pan follow + a verb pill | show where; let the agent read and set the view |
+| Live change outlines during a run | tldraw (streamed), Cursor inline diff | after the run only | draw live |
+| Per-run timeline + revert one | Cursor checkpoints | yes (runs.rs) | per-client runs; fix stale card |
+| Variations side by side | Stitch | none | duplicate + keep one |
+| Comments batched into one prompt | v0 annotations | feedback + annotations exist | "Send open notes to chat" |
+| Voice | Cursor, Stitch | none | P2 |
+
+## 4. Conclusions
+
+1. The best tools send **identity + pixels + region**. PaperCraft sends identity only. Adding a screenshot crop to chips and an area pick is the biggest lever for "point at the canvas".
+2. Split actions into **two lanes**. Deterministic actions (lint autofix, bind hard-coded colors to the nearest variable, swap copies for instances, rename default layers) run in-process through `runs::Tracker::call`, so they land as a reviewable run with no model. Intent actions (Optimize layout, Variations, Make consistent) send a scoped prompt from a template.
+3. A DS in context is necessary but not enough (the Figma Make complaints). Pair the digest with a **reuse check**: lint "looks like component X but isn't an instance".
+4. Presence beats a pill. Outline the nodes the current run touched, live, and say where the agent is (page, frame).
+5. Ghost previews in egui are costly (a second document render path). The cheaper equivalent already exists: apply live, show the run outlines, Accept/Revert per run or per change. Variations give "preview" by construction: siblings on the canvas, keep one.

+# Chat ↔ canvas: spec
+
+What and why for (a) the gaps in `gaps-found.md`, (b) a chat that acts and points at the canvas, and (c) chat grounded in the project's design system. Research and the current-state map are in `research.md`. Cost: **S** < 1 day, **M** 1–3 days, **L** > 3 days. Everything here uses egui primitives already in the tree (Area overlays, painter, popups) and no new crates.
+
+## Principles
+
+* **Two lanes.** Deterministic actions run in-process with no model. Intent actions send a scoped prompt. Both go through `runs::Tracker::call`, so each lands as one reviewable, revertable run.
+* **Identity + pixels + region.** What the user points at goes to the agent as node ids, a crop image, and a world rect.
+* **Reuse before draw.** The agent sees the design system every turn, and a lint flags work that should have been an instance or a token.
+* **Never steal the camera.** Agent camera moves obey the existing `SELF_FOLLOW_QUIET` rule (`src/ui/chat.rs`).

+`get_screenshot {annotations?: bool}`. When true, the image includes note cards, badges and leader lines for notes whose target is inside the captured roots.
+* How: clone the page doc, add each card as temporary frame + text nodes at `annotation_layout` placement (`card_size`, the placement and routing functions), add leader lines as path nodes, then call the existing `io::png::render`. Captured bounds grow to include the cards. No second renderer.
+* Accept: a test renders a frame with 2 notes, and the PNG bounds include both cards. With `false` or omitted, the output is byte-identical to today. `docs/annotations.md` and `skills/papercraft/references/tools.md` are updated.
+
+### P0.2 Viewport: read, set, switch page (gaps 2, 3) — S
+* `get_basic_info` and `get_selection` gain `viewport: {pageId, rect:[x,y,w,h] world, zoom}` from `ed.camera` and `ed.viewport`.
+* New tool `set_viewport {pageId?, nodeIds? | rect?, zoom?, padding?}`. It switches the active page when `pageId` differs (as the page list does) and fits the nodes or rect. `zoom` sets an explicit level within the canvas's min/max, instead of the 1.0 cap in `select_nodes`. It is refused with `"user is moving the canvas"` when the camera moved within `SELF_FOLLOW_QUIET`, unless `force:true`.
+* `select_nodes` keeps its behaviour. Its error on another page points to `set_viewport`.
+* Accept: tests for the page switch, fit, explicit zoom and the quiet refusal. The tool count in `docs/agents.md` is updated.
+
+### P0.3 Runs per agent client + per-run review (gap 7, run-card follow-ups) — M
+* `PaperServer::call_tool` reads `context.peer.peer_info()` (rmcp `clientInfo.name`/`title`) and the session id, and passes `client` on `Call`. Chat turns pass their chat id. `Tracker` keeps one open run per client key, instead of one global `open`. `Run` gains `client: String` (serde default `""`).
+* Agent view and chat: each run shows its client ("Claude Code · subagent 2"). Revert of one run is already in `runs::revert`; refuse it when a later run touched the same nodes, and offer "Restore to here" (`revert_all`).
+* Fix the run card going stale after undo (refresh `ReviewDiff` on `history.generation()` change). The "Working" pill clears on turn end. Stop shows as "Stopped", not an error.
+* Accept: two MCP sessions editing at once give two runs with the right counts. Reverting one leaves the other's nodes. The `tests/mcp.rs` and `runs.rs` tests pass.
+
+### P0.4 Design-system context in every chat turn (user request) — M
+Today `system_prompt()` (`src/ui/chat.rs:602`) is the skill text plus the project name. Add a **DS digest**, built in-process from data the tools already expose:
+* **Variables/tokens**: collection → group → names, with modes. Values only for colors, listed as `name=#hex/#hex(dark)`. Tokens (space, radius, type) as scales. Source: same as `get_variables`.
+* **Components**: page mains and enabled-library mains (`get_components`, `ed.library_docs`), as `componentKey · name · w×h · uses`. Sorted by uses, then name.
+* **Libraries**: enabled libraries with their update status (`libraries::status`).
+* **Annotation template**: the active template's enabled types (`get_annotation_template`).
+* **Rules line**: "Reuse: use `create_instance`/`swap_instance` for anything matching a component; colors must be `var(--…)`; spacing on tokens."
+
+Budget and caching:
+* Cap the digest at ~1,500 tokens (≈6 KB, a named constant). When over the cap, keep the top components by use, collapse variable groups to counts, and append "call get_components / get_variables for the rest".
+* Cache it on `ChatState`, keyed by a hash of (variables, tokens, component keys + names, enabled library versions, template id). Rebuild only on a key change.
+* API backend: the digest goes in the system prompt, in its own cache-breakpoint block after the skill (Claude host). CLI/ACP backends: they get the system prompt once per session, so when the hash changes between turns, prepend `[Design system changed] <digest>` to the next user message.
+* Settings → Chat gets a toggle, "Send design-system summary" (default on), because it costs tokens.
+
+**Reuse check** (the Figma Make failure mode):
+* New lint rule `not-an-instance`: a frame whose structure matches a component main (same child kinds/count, size within 4 px, same text roles) but that is not an instance. Its fix is "swap_instance with componentKey X". Computed with the same structure walk `diff_frames` uses.
+* `lint_design {fix:true}` does **not** auto-swap; swapping is a user action (P0.5).
+
+Accept: a unit test of the digest for a fixture project, checking it is under the cap with top-N kept. A test that the hash is unchanged when unrelated nodes move. A lint test where a hand-made copy of a button is flagged and an instance is not. The context meter shows the added tokens.
+
+### P0.5 Scoped actions on a selection: "Optimize" menu (user request) — M
+An **Actions** menu on the selection. It opens from the canvas right-click menu (extend `canvas_menu` in `src/ui/annotations.rs:438`, which today has only "Annotate"), from an "Actions" chip next to `@ Selection` in the composer, and from the command palette (`src/ui/palette.rs`). It works in Design and Chat modes.
+
+Deterministic lane (in-process, no model, one run each, instant):
+| Action | Runs | Exists |
+|---|---|---|
+| Fix lint here | `lint_design {nodeId, fix:true}` | yes |
+| Bind to tokens | for each hard-coded color, space or radius in the subtree, `bind_variable` to the nearest variable/token within a tolerance; the rest are listed in the result | bind exists; nearest-match is new (S) |
+| Use components | for each `not-an-instance` hit, `swap_instance` | needs P0.4 lint |
+| Rename layers | `rename_nodes` for default names (`Frame 12`, `Text`) from text content or role | new heuristic (S) |
+| Annotate | opens the existing popover | yes |
+
+Intent lane (sends a prompt to chat with a selection chip and crop; switches to Chat mode like "Annotate with AI" does, but **sends**, because the action is explicit):
+* **Optimize**: "Tighten layout and spacing to the token scale, fix contrast to AA, keep the content. Prefer existing components."
+* **Make consistent with DS**: "Replace hand-made parts with instances of the listed components, bind every color and space to variables."
+* **Annotate with AI** (existing), **Write states** (empty, loading, error), **Variations ×3** (P1.3).
+Prompts live in one const table in `src/ui/chat_msgs.rs`, next to `SUGGESTIONS`.
+
+Review: every action, in either lane, ends as a run, so the existing review overlay, Run card and Revert/Accept apply. A deterministic action shows a toast "Bound 14 colors · Review · Revert".
+
+Accept: each deterministic action has a test on a fixture (counts, one undo step, one run). The intent actions put the right prompt and chips into a sent message (pattern: `ai_prompt_and_chat_hand_off_do_not_send`).
+
+### P0.6 CLI/app version check (gap 4) — S
+* `papercraft-cli call`/`shell` compares its own `CARGO_PKG_VERSION` with the app's `serverInfo.version` (`src/mcp/server.rs:39`). On mismatch it prints once to stderr: `papercraft-cli 0.6.1 ≠ app 0.6.2; reinstall the CLI`.
+* `list`/`schema` use the app's `tools/list` when the app is running and fall back to the built-in list offline, so new tools show even from a stale CLI.
+* Accept: a test with a fake server version prints the warning. `list` against a running app includes a tool absent from the built-in list.
+
+## P1
+
+### P1.1 Point at the canvas from chat: pick and area — M
+* The composer gets **Pick** (crosshair; click a layer or Shift+drag an area; Esc cancels) next to `@ Selection`. It does not change the user's selection.
+* `SelChip` (`src/ui/chat.rs:201`) gains `rect: Option<[f64;4]>` (world) and `image: Option<path>`. An area chip is sent as `[Area] page P, rect x,y,w,h, contains: <ids…>` plus the crop image. Layer chips also attach a crop.
+* Crop: `get_screenshot`'s render of the intersecting roots, clipped to the rect (S; add a `clip` rect to `io::png::render`), with annotations per P0.1. Images go through the existing attachment path (image blocks for API; `.papercraft-chat-tmp/` paths for CLI/ACP).
+* ⌥-click on the canvas in Chat mode adds a layer chip directly (Cursor pattern). Chips are inserted at the composer cursor.
+* Accept: an area chip lists the contained node ids and attaches a PNG. Several picks give several chips.
+
+### P1.2 Agent presence and live outlines — M
+* While a run is open, outline the nodes from the last N calls' `follow_node` keys (`chat_msgs::follow_node`) on the canvas in the accent color, fading over 3 s. Label the newest outline with the verb (`agent_verb`) and the client name: an **agent cursor**. Draw it as one `egui::Area` like `review_overlay`, on any page; a chip "Agent on page X →" shows when the agent works on another page.
+* This works for MCP clients too (not only chat), using the per-client run from P0.3.
+* After the turn: today's review overlay. During the turn: cheap touched-outlines only (no full diff per call).
+* Accept: a UI test shows the overlay present while a run is open and gone 3 s after the last call. There is no repaint loop when idle (respect `AGENT_PILL_FRAME_MS`).
+
+### P1.3 Variations side by side — S/M
+* Action "Variations ×3" duplicates the frame 3 times to the right (`duplicate_nodes`, offset by width + 80), names them `<Frame> · Variant A/B/C`, and sends the agent one prompt per variant with distinct directions (compact, spacious, bold). One run.
+* Each variant gets an on-canvas tag with **Keep**. Keep deletes the other variants and the original, or replaces the original with the kept one when "replace original" is on. It is one undo step.
+* Accept: Keep leaves exactly one frame with the original's name and position.
+
+### P1.4 On-canvas Ask popover — S
+* ⌘K on a selection (or "Ask…" in the Actions menu) opens a small prompt box anchored above the selection, using the annotation popover's placement. Enter sends to chat with the chip and crop, Chat mode stays as it is, and the reply streams in the chat column. This gives the Stitch/v0 "type on the element" feel without leaving Design mode.
+* Accept: sending from the popover yields the same message as chip + composer.
+
+### P1.5 Progress for long batches (gap 6) — S
+* The run tracker exposes `calls` and `added/changed/removed` live. The pill shows `Styling · 212 calls · 1,340 changes` for any client, and the chat's step group shows the count while running.
+
+### P1.6 Notes to prompt — S
+* "Send open notes to chat" on a frame: open feedback + annotations of type `todo`/`question` become one batched prompt with a chip (the v0 annotations pattern). It reuses `selection_notes`.
+
+## P2
+
+* **True ghost preview** (L): apply agent edits to a shadow `Document` and draw it translucent over the canvas with Accept/Reject before commit. Costly: every tool would have to target the shadow doc and the renderer composites two docs. P1.2 + P1.3 + run revert cover most of the value; revisit only if users ask.
+* **Dev reload** (gap 5, M): `papercraft --reopen` saves, re-execs the new binary and reopens the project and page. It is a menu item in debug builds.
+* **Chat modes** (S): "Critique" (read-only tools only, returns a list of issues as annotations) vs "Build". It filters `tool_specs()` per mode, as tldraw does.
+* **Sketch to UI** (M): draw on a whiteboard page, then "Make real" sends the crop with the DS digest and the prompt to build a frame next to it.
+* **Voice** (M): push-to-talk into the composer through the OS dictation API. It is out of scope until the other items ship.
+* **Docs** (S, gap 9): document `get_tree_summary` depth with an example; consider `depth` counting from the artboard.
+
+## Out of scope
+
+* New model backends, in-app agent install, web build chat.
+* Gap 8 (fixed). The 0.6.2 platform items (GPU panic, Wayland clipboard, email ellipsis) are tracked in their own specs.

+# Chat: fewer tokens, model and effort, image zoom
+
+## Why
+
+A Claude Code chat turn in the Interview project cost $0.56 (API-equivalent). Most of it was
+a 50k-token prompt prefix written to the cache and re-read on every tool step. Measured with
+`claude -p --model haiku` and the chat's own flags, before anything the user typed:
+
+| Claude Code flags | Prompt tokens |
+|---|---|
+| what the chat sent | 42.7k |
+| `--disable-slash-commands` (no user skills list) | 31.4k |
+| `--setting-sources project,local` (no user CLAUDE.md, hooks, plugins) | 30.6k |
+| both + `--tools Read,TodoWrite,ToolSearch` | 20.6k |
+
+`--tools` without `ToolSearch` makes it worse (43.9k): the CLI then loads every PaperCraft
+tool schema up front. Bash, Edit, Write and the web tools were never usable anyway: in `-p`
+mode only `mcp__papercraft__*` is allowed, everything that needs permission is denied.
+
+The API backend sends all 70 tool schemas (about 77 KB, ~19k tokens) on every request.
+
+## What
+
+1. **Lean Claude Code sessions** (Settings → Chat, on by default): the flags above.
+   Off keeps the user's own CLAUDE.md, hooks, plugins and skills.
+2. **API tool search**: on `api.anthropic.com`, the tools a design turn rarely needs are sent
+   with `defer_loading` behind the BM25 tool-search tool; the core set stays loaded.
+3. **Ask before building**: the chat system prompt tells the agent to ask up to three short
+   questions (with proposed defaults) when a request is too broad to build well, and to
+   avoid screenshots it does not need.
+4. **Model and effort for Claude Code**: the agent panel's Model/Effort block, today only for
+   Claude API endpoints, also shows for Claude Code. Claude Code no longer gets the default
+   API endpoint's model forced on it (a non-Claude default endpoint sent its model id).
+5. **Images: smaller to send, zoom for detail**: attachments are sent at most 1568 px on the
+   long edge (about 1.15 MP, at most ~1.6k image tokens instead of ~4.8k). When an image was
+   scaled down, the original is saved next to the sent one; the `zoom_image` tool returns a
+   region of it at full resolution. It reads only files under the project's chat folder.
+
+## Acceptance
+
+* Claude Code args contain the lean flags when the setting is on, and none of them when off.
+* API request: core tools have no `defer_loading`, the others do, and the tool-search tool is
+  present; non-Claude hosts get the plain full list.
+* A Claude Code chat with a picked model/effort passes `--model`/`--effort`; without a pick it
+  passes neither.
+* A 4000×1000 PNG is sent as 1568×392 and its original is kept; `zoom_image` on the sent path
+  returns a crop of the original; a path outside the chat folder is refused.
+
+## Follow-up: brief, design system, finish (after the binder test)
+
+The binder page (Claude Code, lean) built straight away at 1440x1024 with 44px buttons
+everywhere, no components for the 9 repeated slots, and a 350-word report. The 62.8k context
+was a 20.3k prefix (lean, as measured) plus the agent's own 19.3k tokens of HTML and the tool
+results; each part was written to the cache once. Lean mode also dropped the user's
+`"model": "opus"` from `~/.claude/settings.json`, so the turn ran on Sonnet 5.5.
+
+6. **`ask_user` tool + question card**: one to five questions, two to five options, palette
+   options with swatches; the chat draws clickable chips, "Send answers" and "Use your
+   defaults". The tool only checks the shape and tells the agent to end its turn.
+7. **Chat rules**: a brief before the first design (frame size, density, palette, type, scope,
+   references), variables and components first, sizes from the agreed density, a five-bullet
+   report and next steps through `ask_user`.
+8. **Lint**: `touch-target` asks 24px (WCAG 2.2 AA) inside screens 1024px or wider, 44px on
+   narrower screens and standalone components; the autofix follows.
+9. **Lean keeps the user's model**: with no pick, the chat passes the `model` from the user's
+   Claude Code settings.
+
+## Follow-up: long chats (the Jira chat at 230k)
+
+The Jira chat reached 230k of context; every step re-read it. Claude Code's `total_cost_usd`
+adds up over a resumed session, so turns showed the running total ($6.72 for a $0.47 turn).
+
+10. **Meter**: a 1M window (current Claude models), counts as `1.6M`; amber past 150k.
+11. **Per-turn cost**: `Message::session_cost` keeps the CLI's running total; a resumed turn shows
+    the difference (older saved turns are derived at display time).
+12. **Fresh session past 150k (now 120k)** (CLI backends): not resumed; the new session starts with a recap
+    (the last 8 requests, the last report) and reads the canvas with tools.
+13. **Compact now**: clicking the meter queues the same fresh start for the next message.
+14. **API context editing**: `clear_tool_uses_20250919` past 60k input, keep 4, clear ≥15k, tool
+    inputs too (beta `context-management-2025-06-27`).
+15. **Research sub-agent**: with Web on, Claude Code gets a `researcher` agent on Haiku
+    (`--agents`); it searches and fetches, the main context gets the kept paths only. A research
+    turn on a fresh chat: $0.26 in all, main context 25.8k (the late in-session one cost $1.71).
+    Sub-agent text stays out of the chat; its tool calls (and galleries) show.
+16. **Turn budget** (Settings → Chat, default 10M tokens read): a turn past it is stopped like
+    Stop, with a note.

+# Chat layout: design by conversation
+
+## Why
+
+Today an agent drives PaperCraft from outside: a terminal running Claude Code or Codex, pointed at the MCP server. The app shows a working pill, the agent runs and their review, but the conversation itself lives elsewhere. OpenDesign and Cursor's agent view put the conversation next to the result. PaperCraft already has everything behind that: 61 tools, agent runs with auto-versions and review, skills, design systems and libraries.
+
+## Decisions (user, 2026-10-21)
+
+* Backend: **both** local agent CLIs (Claude Code, Codex) and a bring-your-own-key Anthropic API path.
+* Layout: a separate **Chat layout**, chat column left, live canvas right, switched from the top bar (`Design | Chat`).
+* Conversations live **in the project** (`chats/`), linked to the agent runs they produce.
+* Mock-ups first.
+
+## What exists today
+
+* MCP server on `127.0.0.1:<PAPERCRAFT_MCP_PORT>` (default 29980), loopback only, rejects `Origin` headers (`src/mcp/server.rs`). Every tool runs on the UI thread through `App::run_mcp_calls` and `mcp::exec::call`.
+* Agent runs (`src/runs.rs`): editing calls grouped into runs with auto-versions, review, revert, the finish toast.
+* Tool list and schemas: `mcp::server::tool_list()`, `crate::mcp::tools::edits_doc`.
+* Skills: `skills/papercraft`, `skills/papercraft-design`, `skills/papercraft-design-system` (in repo) and the installed copies under `~/.agents/skills/`.
+* No HTTP client for outbound API calls except `reqwest` (already in `Cargo.lock` through rmcp) and `curl` used by the CLI's icon download.
+
+## Layout
+
+* **Mode switch** in the top bar: `Design | Chat` (segmented control), shortcut ⌘J. The mode is per window and remembered per project.
+* **Chat mode**: left column 420–640 px wide (resizable, default 480), canvas on the right with the normal top bar, zoom and a slim tool strip; the layers, inspector and side views are hidden (a toggle brings the inspector back as a narrow overlay).
+* **Chat column**, top to bottom:
+  * header: chat title (rename), chat list menu (new chat, switch, delete with confirm), agent picker chip (`Claude Code · Opus 5.5`, `Codex · gpt-6.1-sol`, `API · Opus 5.5`) and a settings icon;
+  * message list: user messages; assistant text streamed as it arrives (markdown: paragraphs, lists, code, inline code, links); thinking/progress shown as a collapsed one-line "Thinking…" row when the backend provides it; **tool-call cards**: verb + target ("Drawing layout · Card", from `agent_verb`), status (running spinner, done, failed with the error), collapsible args/result JSON, a thumbnail for `get_screenshot` results; a **run card** when an agent run ends (`Agent finished, N changes` with Review, Revert, Accept, reusing the run review); errors as a red row with Retry;
+  * composer: multi-line input (⏎ sends, ⇧⏎ newline), attachment chips (current selection as `@Frame name` chips added by a button or ⌘L, images by paste/drag, the active page), a Stop button while a turn runs, a model/effort menu for the API backend;
+  * empty state: suggestions built from the project ("Design a sign-in screen using this project's variables", "Lint this page and fix warnings", "Make a dark mode").
+* **Patterns from shadcn AI Elements** (ui.shadcn.com/docs/ai-elements; React components, so only their patterns and names are reused, built from `src/ui/kit.rs`):
+  * **Chat** thread with a message scroller that sticks to the bottom while streaming and keeps your place when you scroll up (a "Jump to latest" pill appears).
+  * **Message**: user and assistant turns; assistant actions on hover (copy, retry).
+  * **Reasoning**: collapsible, streams while open, collapses to "Thought for 12s" when done.
+  * **Tool**: one card per call, states pending / running / done / error, input and output sections collapsible; a screenshot output shows inline.
+  * **Task / Chain of Thought**: consecutive tool calls in one assistant turn group into a step list ("Built the card · 5 steps") that expands.
+  * **Plan / Queue**: when the agent keeps a todo list (Claude Code `TodoWrite`, or the API backend's plan), show remaining and completed items pinned above the composer.
+  * **Confirmation**: approve or deny before destructive tools run (`delete_pages`, `delete_nodes` on more than 20 layers, `disable_library`, `import_design_system`); API backend pauses the loop; CLI backends rely on the CLI's own permission prompt where it exists, else the tool stays allowed and the run can be reverted.
+  * **Checkpoint**: each agent run's auto-version shows as a checkpoint in the thread; "Restore to here" reverts the runs after it (reuses `runs::revert`).
+  * **Context**: a small meter in the header with tokens used of the model's context window (API and Claude Code report usage).
+  * **Model Selector**: backend + model menu and an effort menu.
+  * **Prompt Input**: multi-line field, attachments (selection, images, page), send / stop.
+  * **Suggestion**: one-click prompts in the empty state and after a run ("Lint this", "Make a dark mode", "Review changes").
+  * **Subagent**: a nested, collapsible block when a CLI agent spawns a sub-agent.
+  * **Code Block**: fenced code in replies with a copy button.
+  * Not used: Sources, Inline Citation, File Tree, Terminal, Stack Trace, Test Results (not design work).
+* **Canvas side**: follows the agent: when a tool call targets a node, the canvas pans to it unless the user moved the camera in the last 10 s; the run overlay (green/yellow/red outlines) shows while a run is open.
+* Design mode keeps working as today; the chat keeps running in the background when you switch.
+
+## Backends
+
+All backends drive the same tools, so runs, undo, review and revert work the same.
+
+### Local agent CLIs
+
+* **Claude Code**: spawn `claude -p` with streaming JSON in and out (`--input-format stream-json --output-format stream-json --verbose`), an MCP config pointing at the app's server (`--mcp-config` with `{"mcpServers":{"papercraft":{"type":"http","url":"http://127.0.0.1:<port>/mcp"}}}`), the papercraft tools allowed (`--allowedTools "mcp__papercraft__*"`), working directory = the project folder, and the system prompt appended with the PaperCraft skill text. Resume with `--resume <session_id>` (stored on the chat). Exact flags are checked against `claude --help` at implementation time and wrapped in one adapter.
+* **Codex**: spawn `codex exec --json` with the server added through `-c mcp_servers.papercraft.url=...` (or the current equivalent, checked against `codex exec --help`), resume with its session id. Same adapter shape.
+* **Detection**: Settings → Chat lists the CLIs found on `PATH` (plus a path override) with their version; a missing CLI shows install hints, never an error dialog.
+* **Events**: each adapter turns the CLI's JSON lines into one internal event stream: `Text(delta)`, `Thinking(delta)`, `ToolStart{id,name,args}`, `ToolEnd{id,result|error}`, `TurnEnd{usage?}`, `Error`. Tool calls also arrive through the MCP server, so the card status is confirmed by the app itself (`log_agent`), not only by the CLI's report.
+* **Stop**: sends an interrupt (stdin control message where supported, else SIGINT, then kill after 3 s). The run so far stays reviewable.
+* **Security**: the CLI runs with the user's own permissions and logins; PaperCraft passes no keys. Only papercraft tools are pre-allowed; other tools follow the CLI's own permission settings (non-interactive: denied).
+
+### Anthropic API (bring your own key)
+
+* Raw HTTPS to `POST https://api.anthropic.com/v1/messages` with `stream: true` (no Rust SDK exists), using `reqwest` (already a dependency).
+* **Key**: entered in Settings → Chat, stored in the macOS Keychain (Linux: Secret Service; Windows: Credential Manager) through the `keyring` crate, never in project files or logs. `ANTHROPIC_API_KEY` in the environment is used when no key is stored.
+* **Model**: default `claude-opus-5-5`; menu also offers `claude-sonnet-5-5` and `claude-haiku-5-5`. Thinking adaptive (default on these models), `output_config.effort` set explicitly (default `medium`, menu low/medium/high), `thinking.display: "summarized"` so the Thinking row has text. Server-side refusal fallback on (`fallbacks: "default"` with beta `server-side-fallback-2026-07-01`; for Haiku, show the refusal instead).
+* **Tools**: the app's own tool list (`tool_list()` converted to Messages API `tools`: name, description, input_schema), with `eager_input_streaming: true`; inputs are parsed tolerantly, validated against the schema before running, and run through `mcp::exec::call` on the UI thread like any MCP call (so runs and undo behave the same). Several `tool_use` blocks in one turn run in order and all `tool_result` blocks go back in one user message; failures go back as `is_error: true`. No forced `tool_choice` (not supported on these models).
+* **Loop**: stream → collect `tool_use` → run → append `response.content` unchanged (thinking blocks included) + tool results → next request, until `stop_reason` is `end_turn`; `max_tokens` → continue once with a note; `refusal` → show the category; `pause_turn` → continue. Max 40 tool rounds per user message (then stop and say so).
+* **Caching**: `cache_control` breakpoints on the tool list and on the system prompt (skill text + project context), stable ordering so they hit; per-turn volatile context (selection, active page) goes in the user message, not the system prompt. `usage.cache_read_input_tokens` is logged to verify.
+* **Images**: `get_screenshot` results go back as image blocks so the model sees what it made; user-attached images too.
+* **Cost line**: per turn input/output/cache tokens and an estimated cost from a small price table, shown under the turn in a muted row.
+* Implementers read the bundled claude-api skill files `curl/examples.md`, `shared/tool-use-concepts.md`, `shared/prompt-caching.md`, `shared/model-migration.md` (Opus 5.5 section) before writing this adapter.
+
+### Custom endpoints (generic, no provider list)
+
+The API backend is not tied to Anthropic. Settings → Chat holds one or more **endpoints**, each `{ name, format, base_url, model, key }`:
+
+* `format`: `anthropic` (Messages API, `POST {base}/v1/messages`, `x-api-key`) or `openai` (Chat Completions, `POST {base}/chat/completions`, `Authorization: Bearer`, streaming SSE `choices[].delta`, tools as `{"type":"function","function":{name,description,parameters}}`, `tool_calls` with `arguments` streamed as string fragments, results as `role: "tool"` messages).
+* `base_url`: free text (e.g. `https://api.anthropic.com`, any Anthropic-compatible URL, `http://127.0.0.1:11434/v1`). `model`: free text. `key`: optional (local servers need none), stored in the OS keychain under the endpoint's base URL, never in settings files.
+* Claude-only request fields (`output_config.effort`, `thinking.display`, `fallbacks` and its beta header, `eager_input_streaming`) are sent only when the base URL host is `api.anthropic.com`; other Anthropic-format endpoints get a plain request (adaptive thinking omitted), and are tolerant of missing `usage`, `thinking` blocks, or `cache_*` fields.
+* The cost line shows a price only for models in the built-in Claude price table; otherwise tokens only (or nothing when the server reports no usage).
+* No provider names, presets or logos in the app. A default endpoint `Anthropic` (`anthropic`, `https://api.anthropic.com`, `claude-opus-5-5`) exists so the first-run path stays one key away.
+* The agent picker lists every configured endpoint by its name.
+
+### Not in scope (v1)
+
+* Named provider presets.
+* Multiple chats running at once in one project (one active turn per project).
+* Voice, file uploads other than images.
+
+## Storage
+
+* `chats/<id>.json` in the project folder: `{ id, title, created, updated, backend: {kind, model?, effort?, cli_session?}, messages: [ {role, text, tools:[{id,name,args,result,error,ms}], run_id?, usage?, at} ] }`. API backend also keeps the raw `messages` array (for exact replay, including thinking blocks) in `chats/<id>.api.json`.
+* Chats sync with the project (relay). Deleting a chat deletes both files after a confirm.
+* The project's newest chat opens when entering Chat mode.
+
+## MCP and CLI
+
+* No new tools needed. `papercraft-cli` is unchanged.
+
+## Acceptance
+
+* Chat mode toggles from the top bar and ⌘J; layout matches the mock-ups at 1440p and 1280x800.
+* With Claude Code installed: "Create a 390x844 artboard named Test with a centred title" streams text, shows tool cards for `create_artboard` and `write_html`, the canvas follows, a run card appears at the end, Review/Revert work; a follow-up message continues the same CLI session.
+* Same with Codex.
+* With an API key: the same prompt works through the API backend; thinking row shows a summary; cost line shows tokens; a second turn reads from cache (`cache_read_input_tokens > 0`).
+* Stop during a long turn ends it within 3 s; tools already applied stay and are revertible.
+* Missing CLI and missing key show setup states, not errors; a bad key shows the API error message.
+* Chats persist in `chats/` and reopen after restart; a project without `chats/` loads unchanged.
+* The key never appears in project files, logs or crash output (test greps the project folder and the log after a run).
+* Tests: event parsing for each adapter from recorded JSON fixtures (Claude Code stream-json, Codex --json, Anthropic SSE incl. thinking, tool_use with input_json_delta, refusal, max_tokens); tool-schema conversion; chat file round trip; the API loop with a fake HTTP server (two tool rounds then end_turn).
+* `cargo test --no-fail-fast`, wasm and Windows checks pass (chat backends are native-only; the web build shows Chat mode disabled with a note).

+# Tasks
+
+Stop on failure. Tasks in one wave touch different files and run in parallel; a wave starts when the previous one passes `cargo test --lib`. A read-only review after waves 2 and 4; real findings are fixed before moving on.
+
+## Wave 0: design (parallel with wave 1)
+
+- [x] 0. **Mock-ups** in the `PaperCraft` design file, new page `Chat`: `Chat / Empty`, `Chat / Streaming` (text + tool cards + thinking row), `Chat / Run finished` (run card, canvas overlay), `Chat / Agent picker` (menu open, CLIs found/missing, API), `Chat / Setup` (no CLI, no key), `Settings / Chat`, at 2560x1440 and a 1280x800 variant of `Chat / Streaming`. The user's app had another project open, so this ran through the 0.5.0 offline CLI on the `PaperCraft` project (each call refuses if the app has it open); never `open_file` in the user's app.
+
+## Wave 1: model and storage (parallel)
+
+- [x] 1. **Chat model and storage** (new `src/chat/mod.rs`, `src/chat/store.rs`): types from the spec, `chats/` load/save/list/delete, legacy project without `chats/`. Tests: round trip, listing order, delete.
+- [x] 2. **Event stream and adapters' parsing** (new `src/chat/events.rs`, `src/chat/claude_code.rs`, `src/chat/codex.rs`, `src/chat/anthropic.rs` parsing half): the internal `Event` enum and pure parsers from recorded fixtures (`tests/fixtures/chat/`). Record real fixtures by running the CLIs once on a scratch project with a throwaway prompt (no user data); for the API, build SSE fixtures from the documented event shapes. Tests per backend.
+
+## Wave 2: backends (after wave 1; 3, 4, 5 parallel)
+
+- [x] 3. **Claude Code process** (`src/chat/claude_code.rs`): detect, spawn with MCP config and allowed tools, stream stdin/stdout on a worker thread, resume, stop. Integration test gated on `claude` being on PATH (skipped otherwise).
+- [x] 4. **Codex process** (`src/chat/codex.rs`): same for `codex exec --json`. Gated test.
+- [x] 5. **Anthropic API loop** (`src/chat/anthropic.rs`, `keyring` dependency): key storage, request building (tools from `tool_list()`, caching, effort, thinking display, fallbacks), SSE streaming, tool loop through a channel to the UI thread (`mcp::exec::call`), usage and cost. Test with a fake HTTP server.
+
+## Wave 3: UI (after wave 2 and the mock-ups; 6 then 7 and 8 parallel)
+
+- [x] 6. **Chat layout and mode switch** (`src/ui/chat.rs`, `src/ui/mod.rs`): Design | Chat toggle, ⌘J, column + canvas layout, resizable column, remembered per project.
+- [x] 7. **Messages and composer** (`src/ui/chat.rs`): markdown text, thinking row, tool cards, run card (reuse run review actions), errors with Retry, composer with attachments, Stop, empty state suggestions, agent picker, chat list. Canvas follows tool targets.
+- [x] 8. **Settings → Chat** (`src/ui/settings.rs`): CLI detection and paths, API key (Keychain), default backend/model/effort.
+
+## Wave 4: finish
+
+- [x] 9. **End-to-end check** with each available backend on a scratch copy of a project (own app instance on its own port and `PAPERCRAFT_HOME`), screenshots against the mock-ups, key-leak grep.
+- [x] 10. **Docs and release notes**: `docs/chat.md`, README section and screenshot, `docs/agents.md`, ROADMAP row 44 done, PROGRESS entry; full test suite, wasm and Windows checks.

+# Design from the CLI without the app
+
+## Why
+
+`papercraft-cli call` needs the app running with a project open. Agents on a server, in CI, or on a machine where the app is closed cannot design at all. The code that runs every tool already works without a window: `SessionHost` (`src/mcp/exec.rs:52`) holds an `Editor` and a `Session` and has an offscreen renderer (`Headless`) for screenshots and PNG export. Tests drive it today.
+
+## Scope
+
+1. **Offline calls.** `papercraft-cli call <tool> [JSON]` runs in-process on a `SessionHost` when the app is not reachable, or always with `--offline`. Projects come from the same store (`$PAPERCRAFT_HOME`, else the default folder). `--project <name|id|path>` opens a project first; without it, the most recently modified project is used, and `create_file` / `open_file` work as usual. Every editing call saves before exit.
+2. **Safety.** When the app is reachable, plain `call` keeps going through the app (it is the one with the open file). `--offline` while the app has the same project open is refused ("PaperCraft has this project open; close it or drop --offline"), so two writers never race on one folder.
+3. **Shell.** `papercraft-cli shell [--project X] [--offline]` is an interactive session that keeps one host for many calls:
+   * a line is `<tool> <json>` (JSON may span lines until braces balance), or a command: `:help`, `:tools`, `:schema <tool>`, `:open <project>`, `:pages`, `:page <name|id>`, `:shot [nodeId] [file]`, `:undo`, `:redo`, `:save`, `:quit`;
+   * `:watch on|off`: after every editing call, re-render the artboard last touched (or the page) to `preview.png` in the current folder; on iTerm2, WezTerm and kitty the image is also shown inline in the terminal;
+   * history in `~/.papercraft_cli_history` when a line editor is available; plain stdin otherwise (works in pipes, so `papercraft-cli shell < script.pc` runs a script).
+4. **Preview without a GPU.** If no adapter is found, retry with the fallback (software) adapter; if that fails too, image tools return a clear error and every other tool still works.
+5. **Docs.** `docs/agents.md`: offline use, the shell, scripts. `papercraft-cli --help` updated.
+
+## Not in scope
+
+* A headless MCP server (`papercraft-mcp --offline`); the same host makes it a small follow-up.
+* A TUI canvas.
+
+## Acceptance
+
+* With the app closed: `papercraft-cli call create_file '{"name":"Demo"}'`, then `call create_artboard`, `call write_html`, `call get_screenshot -o out.png` produce a saved project and a PNG; opening the project in the app shows the design.
+* With the app open on project X: `call` goes to the app; `call --offline --project X` is refused; `--offline --project Y` works.
+* `papercraft-cli shell < script` runs a multi-line script and exits 0; a failing tool line exits 1 at the end and prints which line failed.
+* `:watch on` writes `preview.png` after each editing call.
+* Tests: offline call round trip on a temp store, refusal when a fake "app has it open" check says so, shell script parsing (multi-line JSON, commands).
+* `cargo test --no-fail-fast`, wasm `cargo check --lib` and Windows check pass (the CLI binary is native only).

+# Variable collections, shared libraries and assets
+
+## Why
+
+Variables are a flat list of colors plus untyped tokens, copied into every page's `Document` and kept in step by hand (two writers fan out to every page, the remove buttons in `src/ui/confirm.rs` do not). There are no groups, no types beyond color, no aliases, and only fills can bind. Components work only on the page that holds the main: the Design tab lists the active page's components, so a `Design System` page's components are invisible everywhere else, and `create_instance` / `swap_instance` refuse other pages. Nothing can be shared between files except a one-off package import.
+
+Goal: Figma's model, local-first. Collections with modes, slash groups, typed variables with aliases; components usable from any page; any file can publish itself as a library that other files enable and update; a proper place to see and edit all of it.
+
+## Decisions (user, 2026-10-21)
+
+* Libraries: **Figma-style publish**. A file publishes a versioned snapshot; consumers keep a copy and get "Updates available". Files keep working when a library is missing.
+* Variables: **collections + groups + types + aliases**, number variables bindable to geometry and type.
+* UI: a **Variables modal**, a **Libraries modal**, and an **Assets** side view. Design mock-ups first.
+
+## What exists today (checked 2026-10-21)
+
+* Storage: `Document.variables` (active colors), `modes`, `mode`, `tokens` (`src/model/document.rs:15`), one copy per page. Writers: `Tx::set_variable`, `remove_variable`, `rename_variable`, `set_token`, `remove_token`, `set_design_system`, `remove_mode`, `set_variable_in_mode`, `set_mode` (`src/history.rs`); UI `on_every_page` (`src/ui/design.rs:15`); MCP `set_variables`, `set_tokens`, `set_variable_mode`, `import_design_system`, `create_page` (`src/mcp/exec.rs`).
+* Binding: `Paint::Solid { color, var: Option<String> }` holds the CSS name; the color is baked in and `apply_variable` rewrites it. Renderer, SVG and PDF read the baked color only. Tokens are substituted as text when CSS is written (`css::set_variables_in_scope`), no link kept.
+* Readers: codegen (`:root`, `[data-mode]`, Tailwind, DTCG), `get_variables`, `tokens_css`, lint (`lint.rs` match and auto-link), `diff_pages`, inspector var picker.
+* Components: `Node.component`, `InstanceLink { main: NodeId, overrides }`; `Editor::fixup` syncs instances on the same `Document`. `import_components` copies mains between pages with no link back.
+* Project: `project.json` (version 2: v1 to v2 is a no-op manifest step; the version bump makes older apps refuse), `pages/<id>.json` (version 3, migration chain), `versions/`, `runs/`. Projects live in one store folder; relay library mode already syncs every project to every device.
+* Figma import ignores variables and does not link instances.
+
+## Model
+
+### Variables (project level, `design.json` in the project folder)
+
+```text
+DesignSystem
+  collections: [Collection]
+Collection { id, name, modes: [Mode { id, name }], default_mode, variables: [Variable] }
+Variable   { id, name: "color/brand/primary", kind: Color | Number | String | Boolean,
+             values: { mode_id: Literal | Alias(variable id) }, description, hidden: bool }
+```
+
+* **Groups** are the `/` segments of the name (`color/brand/primary` sits in group `color/brand`). Renaming a group renames every variable under it.
+* **CSS name**: segments joined by `-`, sanitized (`--color-brand-primary`). Two variables with the same CSS name across all enabled collections are refused at write time.
+* **Aliases** point to a variable of the same kind in any collection, including a library's. Cycles are refused. A value resolves through aliases per mode.
+* **Active mode** is per page per collection (`PageFile.modes: {collection_id: mode_id}`, default = `default_mode`). A new page inherits the active page's choice.
+* **Numbers** carry no unit; they bind as px. **Strings** substitute as text (font family, shadow). **Booleans** bind to visibility.
+* **One source, one cache.** `design.json` is the only stored truth. Each page's `Document.variables` / `modes` / `mode` / `tokens` become a derived cache rebuilt from it (resolved with that page's modes, keyed by CSS name), so the renderer, codegen, lint, diff and export keep reading what they read today. Every writer goes through one design-system API that updates `design.json`, rebuilds every page's cache and re-applies bindings in one undo step per page.
+* **Migration** (project version 1 → 2): the first page's `variables` + `modes` become collection `Colors` (one mode per existing mode, else `Default`); `tokens` become collection `Tokens` (a px value such as `16px` becomes Number; anything else, including unitless `1.5`, stays String). Existing fill bindings keep working because CSS names do not change. Pages keep their fields as the cache. The manifest version is 2, so an older app refuses the project ("made by a newer PaperCraft") rather than write pages without bindings and never update `design.json`.
+
+### Bindings
+
+* Fills keep `Paint::Solid.var` (CSS name).
+* New `Node.bindings: BTreeMap<field, css name>` for `stroke` (color), `text-color`, `width`, `height`, `gap`, `padding` (all four or per side), `radius`, `font-size`, `line-height`, `opacity`, `visible` (boolean). A bound field is re-applied when the variable, an alias target or the page's mode changes, exactly like fills today. Detaching writes the resolved value and drops the binding.
+* Instances inherit bindings from mains; an overridden field drops it on the instance only.
+
+### Components across pages
+
+* Every main gets a stable `component_key` (created on `create_component`, migrated for existing mains).
+* `InstanceLink` gains `source: Option<Source>`: `None` = same page (current behaviour), `Page(page_id)`, `Library(library_id)`. `main` keeps pointing at the node id inside that source document.
+* Editing a main on page A re-syncs instances on every other page whose link is `Page(A)`, in the same commit (one undo step per touched page). Deleting a main leaves its instances as they are, marked "main missing" (Assets offers Detach or Restore).
+* `create_instance` and `swap_instance` accept a component from any page or enabled library (`componentId` as `pageId:num`, or `componentKey`).
+* `import_components` stays (copy) but is no longer needed for reuse.
+
+### Libraries
+
+* **Publish** (Libraries modal, or MCP `publish_library`): writes `library.json` in the file's project folder: `{ library_id (= project id), name, description, version (counter), published (ms), collections (non-hidden variables), components (every main not named with a leading `_` or `.`, with its subtree and a 256px PNG preview) }`. A diff against the previous publish is shown first ("3 variables changed, 1 component added").
+* **Available libraries** = every project in the store with a `library.json` (relay library mode makes other devices' libraries appear with no extra work).
+* **Enable** in a consumer copies the snapshot to `<consumer>/libraries/<library_id>.json` and records `{library_id, version}` in `design.json`. Library collections show read-only in the Variables modal (aliasable, bindable); library components show in Assets.
+* **Updates**: when the library's `version` is newer than the copy, the Libraries modal and a dot on the Assets tab say "Updates available". Review lists changed variables and components; **Update** replaces the snapshot, rebuilds caches and re-syncs `Library(id)` instances (instance overrides kept). Updates are never applied silently.
+* **Missing library**: the copy keeps everything working; the modal shows "Source not found" with Disable (bindings are detached to resolved values, instances detached) after a confirm.
+* **Disable** with uses left: confirm, then detach as above.
+
+## UI
+
+* **Variables modal** (from Design tab "Open variables", palette "Variables…", ⌘⌥V): left column collections (local, then each library, read-only) with their group tree; main area a table, one row per variable in the selected group, one column per mode; cells edit inline (swatch + hex, number, text, toggle) with an alias picker ("→ color/brand/primary"); add variable (type menu), add mode, add collection, rename and delete (confirm), search, a details pane (description, hidden from publishing, CSS name, where used count). Copy CSS / JSON / Tailwind move here.
+* **Libraries modal** (Share menu "Libraries…", palette, Assets header): "This file" (publish state, description, changes since last publish, Publish), "Libraries" (available libraries with Enable toggles, version, source status), "Updates" (per library review and Update).
+* **Assets side view** (replaces the Library tab icon slot, keeps My shapes as its last section): search; sections This file (grouped by page), each enabled library, My shapes; previews in a grid; click to place at the viewport centre, drag onto the canvas; context menu: Go to main, Detach all, Rename (local only). Instances whose main is missing show a warning row.
+* **Design tab** slims to: modes per collection for this page, a short variables summary with "Open variables", lint. The components list moves to Assets.
+* **Inspector**: every bindable field gets the variable picker (filtered by kind), a bound field shows the variable chip with Detach.
+
+Mock-ups: `PaperCraft` design file, new page `Design libraries`, artboards `Modal / Variables`, `Modal / Libraries`, `Modal / Library updates`, `Panel / Assets` (344x1440 like the other panel states), `Inspector / Bound fields` (344x1440). Modals drawn at 2560x1440 window size and checked at 1280x800.
+
+## MCP and CLI
+
+* `get_variables` returns collections, groups, kinds, per-mode values and aliases (current formats keep working; DTCG nests groups).
+* `set_variables` gains `collection`, `type`, `mode`, `alias`, `description`, `hidden`; old calls (color by name) still work and land in the first collection.
+* New: `create_collection`, `delete_variables`, `bind_variable` (node field ← variable), `publish_library`, `list_libraries`, `enable_library`, `update_library`, `disable_library`.
+* `get_components` lists every page and enabled library with `componentKey` and `source`.
+* Every new tool is classified in `edits_doc` (the existing test enforces it).
+
+## Not in scope (v1)
+
+* Text styles, effect styles, grid styles (roadmap row 9; next).
+* Component variants and properties (row 10).
+* Per-frame mode override (mode is per page).
+* Live links between files without publish.
+* Figma variable import (separate item; the model now has room for it).
+
+## Acceptance
+
+* Migration: a project with variables, modes and tokens opens as version 2 with collections `Colors` and `Tokens`; every existing fill binding still resolves; 0.4.0 refuses a migrated project with a clear "made by a newer PaperCraft" error instead of losing data.
+* Groups: renaming group `color/brand` renames its variables and every binding follows.
+* Aliases resolve per mode; a cycle is refused; deleting an aliased variable asks first and detaches dependents to resolved values.
+* Number bindings: changing `space/md` from 16 to 24 updates the gap of every bound frame on every page in one undo step per page; switching a page's mode updates its bound fields only.
+* Removing a variable or mode from the UI affects every page (fixes today's page-only removal).
+* An instance on page B of a main on page A updates when the main changes; undo on A and B each restores its side.
+* Publish → enable in another project → instance and binding work; change and republish → consumer shows Updates available → Update re-syncs instances and keeps overrides; deleting the library project leaves the consumer working with "Source not found".
+* Two libraries defining `--color-bg` cannot both be enabled without a clear error.
+* Variables modal, Libraries modal and Assets view match their mock-ups at 1440p and 1280x800 (screenshot check).
+* `cargo test --no-fail-fast`, wasm and Windows checks pass; web build loads.

+# Tasks
+
+Each task is independently testable. Stop on failure. Tasks in the same wave touch different files and can run in parallel; a wave starts when the previous one passes `cargo test --lib`. After each code wave a read-only Codex `gpt-6.1-sol` review; real findings get fixed before the next wave.
+
+## Wave 0: design (parallel with wave 1)
+
+- [x] 0. **Mock-ups** in the `PaperCraft` design file, new page `Design libraries`: `Modal / Variables`, `Modal / Libraries`, `Modal / Library updates`, `Panel / Assets` (344x1440), `Inspector / Bound fields` (344x1440). Reuse the `Design System` page variables and components. Only through the user's running app after `get_basic_info` confirms the open file is `PaperCraft`; never `open_file` in the user's app.
+
+## Wave 1: model (parallel)
+
+- [x] 1. **Design-system model** (new `src/variables.rs`). Types from the spec (`DesignSystem`, `Collection`, `Mode`, `Variable`, `Kind`, `Value`), ids, CSS name, group helpers (list groups, rename group), alias resolution per mode with cycle check, duplicate CSS name check, `cache_for(page modes) -> (variables, modes, mode, tokens)` producing today's `Document` fields. Tests: groups, rename group, alias chain, cycle refused, duplicate refused, cache matches today's shape.
+- [x] 2. **Storage and migration** (`src/project/format.rs`, `src/project/mod.rs`, `src/session.rs`). `design.json` load/save next to `project.json`; project version 2 with a `PROJECT_STEPS` step building collections `Colors` and `Tokens` from the first page; `PageFile.modes` per collection; `component_key` for existing mains. Tests: v1 project migrates, round trip, a v2 project's page files still deserialize in the old reader shape.
+- [x] 3. **Bindings field** (`src/model/node.rs`, `src/model/paint.rs`). `Node.bindings`, `InstanceLink.source`, `Node.component_key`, all `serde(default)`. Tests: old pages load; serialization skips empty fields.
+
+## Wave 2: wiring (after 1–3; 4 then 5 and 6 in parallel)
+
+- [x] 4. **One write path** (`src/history.rs`, `src/editor/*`). Design-system edits update the project `DesignSystem`, rebuild every page's cache and re-apply fill and field bindings, one undo step per page; replace `on_every_page` and the page-only removals in `src/ui/confirm.rs`. Per-page mode switch. Tests: number binding change on two pages; mode switch only touches its page; undo per page.
+- [x] 5. **Field bindings applied** (`src/editor/structure.rs`, layout). Apply bound stroke, text colour, size, gap, padding, radius, font size, line height, opacity, visible; instance sync carries bindings; detach writes resolved values. Tests per field.
+- [x] 6. **MCP and exports** (`src/mcp/exec.rs`, `src/mcp/tools.rs`, `src/mcp/codegen.rs`, `src/design_system.rs`). Extended `get_variables` / `set_variables`, `create_collection`, `delete_variables`, `bind_variable`; DTCG nests groups; old calls still work. Tests: old and new call shapes, DTCG groups, `edits_doc` classification.
+
+## Wave 3: components across pages (after wave 2)
+
+- [x] 7. **Cross-page instances** (`src/editor/structure.rs`, `src/mcp/exec.rs`). `Source::Page` sync on main edit, create/swap from any page, "main missing" state. Tests: edit main on A updates B; undo per page; delete main leaves instance flagged.

+## Wave 4: libraries (after wave 3; 8 then 9)
+
+- [x] 8. **Publish and enable** (new `src/libraries.rs`). `library.json` writer with previews and publish diff, available list from the store, enable copies snapshot, library collections and components resolvable (`Source::Library`), duplicate CSS name refusal. Tests: publish, enable in second project, binding and instance work, conflict refused.
+- [x] 9. **Updates and missing sources** (`src/libraries.rs`). Version compare, review diff, update keeps overrides, missing library keeps working, disable detaches after confirm. MCP `publish_library`, `list_libraries`, `enable_library`, `update_library`, `disable_library`. Tests per path.
+
+## Wave 5: UI (after wave 4 and the mock-ups; 10, 11, 12 in parallel, then 13)
+
+- [x] 10. **Variables modal** (new `src/ui/variables.rs`). Screenshot check against `Modal / Variables`.
+- [x] 11. **Libraries modal** (new `src/ui/libraries.rs`). Screenshot check against `Modal / Libraries` and `Modal / Library updates`.
+- [x] 12. **Assets view** (`src/ui/library.rs` becomes Assets). Screenshot check against `Panel / Assets`.
+- [x] 13. **Design tab and inspector** (`src/ui/design.rs`, `src/ui/inspector.rs`, palette entries). Slim Design tab; variable picker on every bindable field. Screenshot check against `Inspector / Bound fields`.
+
+## Wave 6: finish
+
+- [x] 14. **Docs and verify**. `docs/design-system.md`, `docs/agents.md` (new tools, count), `ROADMAP.md` rows 7, 8, 12, `PROGRESS.md`; skills `skills/papercraft*` mention collections, bindings and libraries. Full `cargo test --no-fail-fast`, wasm and Windows checks, web build loads.

+# Package A report: Interview Design System
+
+Date 2026-10-23. Project `Interview` (fileName verified). Backup: `/Volumes/Storage/Projects/Interview.backup-20261023-0112`. Screenshots in `A/` (before-*, after-*). Mapping files: `variable-mapping.csv`, `component-mapping.csv` (old name, new name, componentKey, action; 280 rows).
+
+## 1. Variables (collection `Colors`)
+- 161 -> 137 variables (25 merged, +1 `color/brand/primary-strong`). All names are `color/<group>/<name>` (csv `new` column with `color/` prefix). SYS-03: named by role, not value.
+- Rename = create new + repoint every bound fill (`update_styles`) + delete old. The app has no rename tool, and `delete_variables` detaches fills, so repointing was required. 4293+ bound fills repointed on all 3 pages. No dangling `var(--old)` found afterwards.
+- Merges (csv "merge" rows) repointed to the canonical variable then deleted (no leftover aliases needed because nothing binds them).
+- SYS-02 (semantic alias over primitive value): `color/brand/pressed` and `color/text/link` are aliases of `color/brand/primary-strong` (#0958d9); `color/status/info` is an alias of `color/brand/primary`.
+- Contrast: `#1677ff` + white = 4.10:1 FAIL, `#0958d9` + white = 6.16:1 pass (`playbook contrast`), `#0958d9` on `#e6f4ff` 5.50:1 pass (SYS-05). 40 DS fills (Button / Primary x3, Avatar x5, sidebar active items, dots, brand marks, OK button) rebound to `primary-strong`; 16 literal `#1677ff` text nodes now use `text/link` colour. DS contrast errors 128 -> 67 on the original components.
+- Final groups (Colors): avatar 5, bg 6, border 4, brand 6 (primary, primary-strong, pressed, hover, secondary, focus-ring), button 1, camera 2, code 2, control 1, diff 2, hero 2, ide 31, status 9, sidebar 8, syntax 7, syscheck 6, tag 18 (tag/<hue>/{bg,border,text}), text 6, whiteboard 9, auth 12.
+- Colours the page still uses as hard-coded literals (text colours, borders) are not bound; that is B/C work (tools bind fills only).
+
+## 2. Tokens
+- Old `Tokens` collection (32: 26 number, 3 shadow strings, 4 z-index strings) deleted; shadows and z-index dropped (unsupported in PaperCraft, unreferenced). Empty `Tokens` collection remains (no delete-collection tool; remove in the Variables modal).
+- New collection `Spacing & Size` (34 Number variables): `space/{4,8,12,16,24,32,48,64}` (12 added), `radius/{sm4,md8,lg12,xl16,pill999}`, `font/size/{xs12,sm14,md16,lg20,xl24,2xl32,3xl40,4xl48}` (18 dropped), `font/leading/{xs16..2xl40}`, `layout/page-padding(-lg)`, `layout/page-width/{xs480,sm420,md720,lg900,xl1100}` (3 duplicate widths removed). SYS-01/SYS-02.
+- Nothing is bound to them yet (tokens are substituted when written). Use `bind_variable` in later work.
+
+## 3. Components (Design System page: 211 -> 260 mains)
+- Consolidated: Ant Button Primary/Default/Danger (9), Ant Tag (5), Ant Segmented (3), Ant Table (2) dropped after `swap_instance` of their DS cells to the kept set (19 swaps, 19 mains and 19 cells deleted). Ant Text / Text Danger kept as `Button / Text` and `Button / Danger Text` (SM/MD/LG). AntD showcase groups removed, cells moved into `Group / Buttons`.
+- 78 mains renamed to `Group / Variant [/ SM|LG]` (see csv). Button MD height 34 -> 32 (SM 28, LG 40). `Page Header` kept as `Header / Page` (no action slot; not equal to `Header / Admin`, so not merged).
+- Fixed: `Header / Candidate` height 0 -> 134 (Header Card height 100% -> fit-content). 8 `Alert / *` 456/478/522 -> 38 high (message text width 0px -> fit-content).
+- Moved 68 page-local components onto the DS page (17 Admin, 51 Candidate): each moved with `move_nodes toPageId`, instances on the source page re-pointed with `swap_instance` by componentKey, instance layer names updated. Packed at x=1560, y 8623..13765 on the DS page. `Candidate Message / Success` renamed `Banner / Success` (name clash with the Admin one, different design).
+- Skipped (not moved): `T Hdr`, `T Donut`, `T Spark`, `T Stat` (Admin template stubs, 0 uses; equivalents exist in DS: Section Title, Donut, Sparkline, Stat). Delete them in package B.
+- Not done: collapse of combinatorial variants (Segmented Active N, Tabs Bar N, 11 sidebars, content-baked Challenge Option/Timeline, colour-named Stat/Sparkline), missing states (hover/disabled etc.), Input/Select/Textarea LG state matrix (SYS-06/07 follow-ups), `Light` mode rename of `Default` (no tool).
+- Side effect: while moving, Admin's own copies of `Button / Primary Small`, `Button / Primary Large`, `Button / Default` were moved by mistake (the copy filter used renamed names) and then deleted from DS; no Admin instance pointed at them (nested ones live inside other instances). B should re-import or swap to the DS mains below.
+- Admin/Candidate still carry their old copies of the other 211 DS components under old names; B/C: use `component-mapping.csv` and `swap_instance componentKey`.
+
+### Kept component keys (packages B and C)
+`componentKey` for every kept or moved main is in `component-mapping.csv` (column 3). Frequently needed:
+Button / Primary `64e1d4aaf56fe6a4:5980`, Primary / SM `:5982`, Primary / LG `:5984`, Secondary `:5986`, Secondary / SM `:5988`, Secondary / LG `:5990`, Ghost `:5992`, Danger `:5998`, Dark `:6004`, Icon / Bell `:6010`.
+Header / Admin `64e1d4aaf56fe6a4:6480`, Header / Page `:6476`, Header / Candidate `:6489`, Header / Admin / With Action `1c5e5918`.
+Form Field / Default `:6663`, Card / Default `:6054`, Alert / Error `:6728`, Input / Default `:6575`, Sidebar / Admin `:6906`, Sidebar / Candidate `:7370`.
+(Key prefix is the DS page id `64e1d4aaf56fe6a4`.) Moved components have short keys (e.g. `bd7f34e5`), see csv.
+
+## 4. Annotations
+Template `Dev handoff` set on the DS page. 11 notes (dev, a11y, behaviour): one Primary per screen and contrast pair, tag colour by status, Data Table single set, Segmented, Input states, Alert, Tab hit area, Form Field, Header variants, Pill.
+
+## 5. Lint (DS page, byRule)
+Before: contrast 128, hard-coded 11, layer-name 7, spacing 57, touch 16, type-scale 42 (list truncated at 200; counts exact).
+After (whole page): contrast 194, hard-coded 366, layer-name 49, spacing 180, touch 30, type 135. The rise is the 68 moved local components (contrast 127, hard-coded 225, layer-name 42, spacing 123, touch 9, type 93). The original components: contrast 67 (-61), hard-coded 146 (more literals now match a single variable after merges, so lint flags them), layer-name 7, spacing 57, touch 21 (Button MD 32 < 44, desktop density accepted, documented in annotation), type-scale 42. Remaining contrast: `#52c41a`/white 2.3, `#8c8c8c` 3.4 (placeholders), `#bfbfbf` 1.8 (disabled), tag text pairs, IDE greys: design decisions left for follow-up. `lint-ds-before.json` saved in `A/`.
+
+## Leftovers for the user
+Empty `Tokens` collection; mode `Default` not renamed; 15 `Label / *` stubs at x=30000 not deleted; Colors board has no swatch for `brand/primary-strong`; `brand/hover` (#4096ff) with white text fails contrast (hover state unused in DS).

+# Package A2 report: Design System page cleanup
+
+Date 2026-10-23. Project `Interview` (fileName verified). Page `Design System` only. Evidence in `A2/`: `issues-before.json` (all 959 issues, linted per top-level frame to avoid the 200 cap), `issues-7.json` (final), `after-brand-swatch.png`, `after-components.png`.

+
+## What changed
+- Hard-coded colours: 359 nodes bound by exact hex match (352 text colours, 12 fills) via `update_styles` `var(--color-...)`. White text bound to `color/text/inverse`, not `bg/surface` (same hex, text role). Note: `bind_variable text-color` was not recognised by lint, `update_styles color:var()` was; use that.
+- Contrast (SYS-05, A11Y checked with `playbook contrast` maths, all pairs >= 4.5):
+  - white on `#1677ff`/`#4096ff` -> parent fills rebound to `color/brand/primary-strong` (#0958d9, 6.16); 16 fills + 5 matching 1px strokes bound.
+  - white on `#52c41a` (Score Dots) -> `color/status/success-text` (#237804, 5.59); white on `#ff4d4f` -> `color/status/error` (5.57).
+  - `#5a5a5a` on `#1a1a1a` -> `color/ide/text-muted` (4.91); `#888`/`#666` on `#252526|#2a2a2a|#252525|#181818|#161616` -> `color/ide/text-dim` (>= 7.5); `#5a80a8` on `#1c2a40` -> `ide/text-dim`; `#13a8a8` on `#1a3540` -> `syntax/type` (6.33); sidebar `#64676c` -> `sidebar/text-muted` (4.51).
+  - `#8c8c8c`/`#bfbfbf`/`#bbb`/`#878787`/`#848484` on light -> `color/text/secondary` (6.7-7.0). Note placeholders and disabled input text now read as secondary text; disabled look is carried by the grey fill only.
+  - `#52c41a`, `#16a34a` text on light -> `status/success-text`; white on `#faad14`/`#13a8a8` (Score Dots 2, Theory Next) -> `color/text/primary`.
+  - Variable VALUES changed (global, affects Admin and Candidate too, all pairs now pass): `color/tag/gold/text` #ad6800 -> #874d00, `color/tag/green/text` #389e0d -> #237804, `color/tag/cyan/text` #08979c -> #006d75. Bound fills followed automatically.
+  - `Pipeline Row / Dark` was a transparent component meant for a dark card: gave it `color/ide/card` background, stage text `ide/text-muted`, name `text/inverse`.
+- Spacing: all 180 off-grid nodes bound to `space/*` (nearest in-scale value: 1,2,3,5->4; 6,7,9->8; 10,11->12; 14,18->16; 22->24; gap 6->8). On-grid padding was not rebound (would be thousands of bindings with no lint effect). Visual check of buttons, tags, rows, toolbars: nothing broke.
+- Radii: all uniform radii bound to `radius/*`: 289 -> sm (3,4,5), 442 -> md (6,7,8), 75 -> lg (12), 153 -> pill (99,999). Multi-value radii (per-corner) not touched; no radii above 12 other than the pill ones existed.
+- Colors board: added swatch `color-brand-primary-strong` (#0958d9) in the Brand card.
+- `Label / *` stubs: they are plain label frames, not components (`get_components` lists none), and each captions a real component at x=30000. Deleted only the 5 whose component has 0 instances (`Link Field / Copied`, `Challenge Option / Two Sum Off`, `... / URL shortener On`, `... / JavaScript closures Off`, `Timeline / Step 3`). The other 10 kept because their component has instances. Delete them too if you read the instruction as "all 15".
+
+## Skipped / accepted
+- 7 hard-coded: `#000000` text on `Stars / 0..5` (6, no exact variable; `text/primary` is #000000e0, near match not in the audit mapping) and `#bae0ff` on `Funnel Row` (1, no variable).
+- Touch targets (30): `Button *` SM 24-28, MD 32-34, LG 40, `Button / Undo|Clear|Delete` 24, bell 36. Accepted desktop density: playbook A11Y-09 (24 px AA minimum, 44 default on touch only) and PAT-06 (about 27-30 px practical floor for dense content). All >= 24 px. Annotation on the DS page already documents it. Candidate pages are desktop IDE flows.
+- Untouched (out of scope): type-scale 135, layer-name 49, `brand/hover` (#4096ff) with white text (state unused).
+- Side effect to check: `set_variables` (tag text values) made lint report hard-coded text again on untouched nodes (text bindings seemed to be flattened for some nodes on the DS page); rebinding fixed it. Admin/Candidate pages were not inspected for this; if B/C see text colours turn literal, that is the cause.

Marcos Paulo	c5bd4c650d	fix(ui): Enter, Escape and clicking away end a rename again The project, library asset and version rename fields asked for focus every frame before checking `lost_focus()`. In egui 0.36 `lost_focus()` reads the focus as it is at the call, so taking it back first hid Enter, Escape and a click elsewhere: the field could not be left. Focus is now taken back only while the edit goes on. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-24 19:12:05 -03:00
Marcos Paulo	1b795fa971	feat: 0.7.0 chat images, web research, image generation, plugins, fewer tokens Images: paste from the clipboard into the chat, thumbnails and a lightbox for what is sent, image-only messages, attachments sent at 1568px with the original kept for zoom_image. Brief and finish: ask_user question cards (swatches, reference tiles, the recommended answer), chat rules for a brief, design system first, density, short reports and next steps. Research: the composer's Web chip, fetch_reference_images (public addresses only; icons, logos and backdrops dropped), a References gallery, and a Haiku researcher sub-agent on Claude Code. Image generation (opt-in): Codex, Google Flow (gf) or a custom command. Plugins page: Avataaars, DiceBear, Iconify, Lorem Picsum, Flags and QR codes through <x-plugin>; SVG import draws masked groups as images. Tokens: lean Claude Code sessions, deferred tool schemas and context editing on the API, a fresh session with a recap past 120k or on demand, per-turn and chat totals, a 1M context meter, a turn budget, model and effort pickers. Also: page switcher in Chat, no flicker while steps run, desktop target size in lint, the installer keeps papercraft-mcp current.

Marcos Paulo	872b693373	feat: lazy page loading, annotation layout, chat canvas tools - Lazy project loading: the page in view first, the rest in the background; fix the endless repaint and memoise layer heights. - Annotations: placement off screens, straight routing inside the target's screen, zoom-stable lines, badges below 60% zoom, Tidy, custom templates (upsert/delete_annotation_template). - Chat: design-system digest each turn, Actions menu on a selection (fix lint, bind to tokens, use components, rename layers, agent prompts), Pick / area chips with crops, ⌥-click, ⌘K Ask, live agent outlines and counts, one run per MCP client with per-run revert, Stop shown as Stopped. - MCP: set_viewport, viewport in get_basic_info/get_selection, screenshots with annotations, find_nodes substring search, get_tree_summary fullText, annotate tidy returns tidied count, not-an-instance lint. - Fixes: write_html links cross-page components instead of copying them; instance roots keep their own layout when synced or swapped; CLI saves screenshots itself (the app writing to a removable volume froze it behind a macOS prompt), offline write lock, version check, --online. - tools/install-local.sh installs the CLI and signs with a stable identity when present; Dockerfile adds the D-Bus packages the relay needs.

Marcos Paulo	73353dd4ca	feat: any agent via ACP, annotations with templates, chat fixes Chat: agents are found on the login-shell PATH, so apps launched from the Dock see claude, codex and Homebrew CLIs. A generic Agent Client Protocol backend runs OpenCode, Gemini CLI, Cursor, Pi (pi-acp) and others from a data registry, plus custom agents; papercraft tools are auto-approved only when announced and not destructive. New agent panel and Settings > Chat layout, sign-in card, several @ selections, no install instructions. Fixes Send silently doing nothing when the CLI path was set in Settings. Annotations: numbered notes with leader lines that explain a design. Categories drive the look; templates (project default, per-page) choose which kinds are used. Annotate tool (N), side view, Customize, inspector section, Annotate with AI, view modes (Cmd+Shift+A). MCP: annotate (batched), get/update/delete, get/set_annotation_template; notes appear in get_design_spec and get_jsx and in agent-run review and revert.

Marcos Paulo	13bc2d582e	feat: Chat mode with Claude Code, Codex and generic API endpoints A Design \| Chat layout (Cmd+J): a chat column next to the live canvas. Agents run through PaperCraft's own tools, so agent runs, undo, review and revert work as for any MCP client. The thread shows streamed text, reasoning, tool cards grouped into steps, the agent's plan, approvals for destructive tools, checkpoints with Restore to here, run cards and usage. Chats are saved in the project under chats/. Backends: Claude Code (claude -p stream-json) and Codex (codex exec --json) with the app's MCP server, using their own logins; or any API endpoint in Anthropic Messages or OpenAI Chat Completions format with a key kept in the OS keychain. Settings > Chat configures them. Also: the offline CLI no longer saves a camera fitted to a fake window, and top-level shapes without a position go to the next free spot.

Marcos Paulo	30dba88e1c	feat: variable collections, shared libraries, assets and offline CLI Variables move to a project-level design.json: collections with their own modes, slash groups, color/number/string/boolean types and aliases. Pages keep a derived cache, every writer goes through one path, and a change reaches every page in one undo step per page. Strokes, text color, size, gap, padding, radius, font size, line height, opacity and visibility can bind to variables. Projects migrate to version 2. Components work across pages, and any file can publish itself as a library that other files enable, update after review, or disable. New Variables and Libraries modals, an Assets view grouped by name prefix, variable pickers in the inspector, and a slimmer Design tab. papercraft-cli runs tools in-process when the app is closed, with a `shell` command for interactive sessions and scripts. Also centres the sidebar footer and title bar text on their icons. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-21 17:47:23 -03:00
