From 34f8d25089d5573c8f372fbadc5befad88862756 Mon Sep 17 00:00:00 2001 From: Devin Foley Date: Sat, 31 Oct 2026 20:06:32 -0700 Subject: [PATCH] fix(github): expose review finding categories (#18429) ## Thinking Path > - Paperclip manages AI agents and their work. > - GitHub review bots submit structured assessments through task-bound tools. > - Each repository can set its own finding categories. > - The schema accepts a string, but the server rejects values outside the saved review policy. > - Review instructions did not list the accepted values. The error did not list them either. > - This change gives agents the values before submission and keeps server validation. ## Linked Issues or Issue Description **What happened?** Review submissions failed with an unknown finding category. The agent corrected the assessment before publication. The sampled trace has two rejections followed by a processed review. Historical tool inputs are null. Authorized diagnostic inspection found no saved raw provider trace for the representative run. The exact rejected values remain unknown. **Expected behavior** Agents can find the accepted categories before submission. Unknown values still fail validation. **Steps to reproduce** Set a custom finding category. Start a review. Submit a different category. Before this change, the instructions and error do not list the accepted value. ## What Changed - List configured categories in manual and automatic review instructions. - Return categories from the saved assessment policy in `begin_review`. - Describe the dynamic constraint in the shared discovery schema. Keep custom categories valid. - List accepted values in category errors. Keep authorization and publication checks. - Add contract and database integration tests. Update documentation and access maps. ### Hypothesis and thesis for a fix The missing category guidance can cause avoidable submission retries. A model can also ignore the policy returned by metadata reads; the historical inputs do not establish which occurred. The repair belongs to the GitHub review contract. Use the saved policy categories at review start, explain the constraint, and retain server rejection. A fixed global enum would reject valid custom categories. ## Verification - Baseline `f1d7808`: two new contract assertions failed for missing category guidance and error detail. The same assertions pass after the change. - `pnpm exec vitest run server/src/services/chat-github-review-policy.test.ts server/src/services/chat-github-tools.test.ts`: 41 passed. - `pnpm exec vitest run server/src/__tests__/chat-channels.integration.test.ts -t 'returns snapshot finding categories'`: 1 passed. Real PostgreSQL and service code; simulated GitHub HTTP. Checks policy changes, rejection before publication, accepted custom category persistence, and processed publication. - `node scripts/check-maps.mjs`: passed. Structural evidence only. - Shared TypeScript check passed. Server TypeScript checking was killed by the 8 GiB memory limit, including a separate retry after the other checks stopped. - Full typecheck and build could not complete: `cargo` is absent. Full tests were stopped after concurrent checks exhausted memory. CI must supply the full checks. - Follow-up compiler repair: the unchanged baseline reproduces TS2352 in the category discovery test. Runtime matchers replace the unsafe schema cast. They retain both guidance and custom-category assertions. The repair is commit `0dcb94c676`, with current master merged at `14d7052854`. The final head is `c46b8f35add9255fc71be294d27f5a7865bcb47f`; the remaining code-comment review finding was removed and resolved. - Final-head CI: all gates pass, with no failed or pending checks. Greptile gives this head 5/5 with no outstanding findings; the only inline thread is resolved. The workspace test shard passed on one bounded rerun after an earlier CLI child-server readiness timeout; no code change was made for that rerun. - The review host passed full recursive typecheck and build after the compiler repair and master integration. Fresh database rechecks hit the host PostgreSQL semaphore limit. The full local test command hit a pre-existing chat line-selection failure before assertions. These local limits do not replace the passing final-head CI evidence. - No live model or GitHub publication at the changed revision. No deployment or merge. ## Risks - Instructions add policy text. An agent can still ignore it. - Existing bot catalogs get the schema description when tools are synchronized. Trusted review instructions and `begin_review` also expose categories. - The service test uses simulated GitHub HTTP. It does not prove that deployed agents avoid retries. ## Model Used The original worker used OpenAI `gpt-6.1-sol` through Codex with reasoning, tool use, and code execution. A later Codex review repaired the test compiler error. That review runtime exposes GPT-6 but no exact snapshot or context-window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: devinfoley <139239+devinfoley@users.noreply.github.com> Co-authored-by: Paperclip Co-authored-by: Dotta Co-authored-by: cryppadotta <34892728+cryppadotta@users.noreply.github.com> --- doc/connections/GITHUB-REVIEW-BOT.md | 9 +++++ maps/agent-access-map/chat-channels.md | 9 +++++ maps/feature-map/chat-channels.md | 9 +++++ packages/shared/src/validators/chat-github.ts | 4 ++- .../chat-channels.integration.test.ts | 34 ++++++++++++++++--- .../chat-github-review-policy.test.ts | 21 ++++++++++++ .../src/services/chat-github-review-policy.ts | 4 ++- server/src/services/chat-github-reviews.ts | 1 + server/src/services/chat-github-tools.test.ts | 17 ++++++++++ 9 files changed, 101 insertions(+), 7 deletions(-) diff --git a/doc/connections/GITHUB-REVIEW-BOT.md b/doc/connections/GITHUB-REVIEW-BOT.md index af4d979bebd..e3a85ee434a 100644 --- a/doc/connections/GITHUB-REVIEW-BOT.md +++ b/doc/connections/GITHUB-REVIEW-BOT.md @@ -200,6 +200,15 @@ and submits the reviewed commit, findings, rationale, and coverage.
