From e8ebc5436229f87333c8610ef12930713d5aa6dc Mon Sep 17 00:00:00 2001 From: Marcos Date: Thu, 20 Aug 2026 17:45:51 +0000 Subject: [PATCH] =?UTF-8?q?feat(review):=20ADDITIONAL=5FCONTEXT=5FURL=20?= =?UTF-8?q?=E2=80=94=20repo-provided=20static=20context=20cached=20per=20r?= =?UTF-8?q?eview?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Long agent loops re-send the brief prefix on every step; cheap reusable knowledge (architecture summary, module map, conventions, glossary) belongs in a versioned file the maintainers control so the agent doesn't re-derive it from the source tree on every PR. Two wiring paths, merged (env first): * env var PRAGENT_ADDITIONAL_CONTEXT_URL — comma-separated, deployment-wide * .pr-review.json:additional_context_urls — list[str], read from the PR's base branch (same trust boundary as the rest of the file) Implementation: * _parse_additional_context_env splits/dedupes/trims. * _resolve_additional_context_urls(config) merges env (first) + config (then, skipping env-dupes); caps at 8. * fetch_additional_context(urls) fetches each URL with urllib (5s timeout, http/https only — file://, javascript:, ftp:// rejected defensively), caches by URL in a module-level dict for the pod lifetime, truncates per-URL to 4k chars + total to 16k chars, best-effort (network errors are logged and skipped — never aborts the review). * Result injected into build_user_prompt under "## Repo-provided context" between repo config and prior reviews. In the opencode engine it lands in .pragent/brief.md under its own section. The brief explicitly labels each block's CONTENT as untrusted (same as PR description) — section heading is trustworthy, body isn't. * parse_repo_config accepts the field, caps at 8 entries, drops non-strings and empty strings. Docs: pilot/README-webhook.md "Repo-provided static context" section — env var + JSON example + Nexus raw-hosted recipe. Tests: 14 new (208 total), covering env merging + dedup, scheme rejection, per-URL cap, total cap, caching by URL, brief injection. All mock urllib with a context-manager stand-in (no real network).
