+# Hands-on · Rules
+
+A tiny, zero-dependency demo showing how rule sources reshape the same prompt.
+
+## Run
+
+Open `index.html` directly. No build, no server, no `npm install`.
+
+## What it shows
+
+- Five rule sources, taken from a real monorepo (`netcracker/interview`):
+  - `AGENTS.md` — repo-wide instruction file.
+  - `.agents/skills/gate-discipline/SKILL.md` — skill body loaded on demand.
+  - `.husky/pre-commit` — git hook that runs other enforcers.
+  - `scripts/check-ui-contract.mjs` — custom CLI enforcer (ratchet).
+  - `commitlint.config.cjs` — commit-msg linter.
+- Each rule has an on/off switch. Toggling a rule prepends its body to the **ruled** prompt.
+- EN ↔ PT toggle keeps both languages useful.
+- "Copy ruled prompt" copies the current ruled-prompt text to clipboard.
+- Responsive on mobile, Full HD, and 4K (one column under 720 px).
+
+## Mirror of `/hands-on/starter`
+
+Same visual system as the starter (`--paper`, `--ink`, `--blue`, `--gold`). Drop-in replacement under `hands-on/rules/`.
