## Thinking Path > - Paperclip manages AI agents and their access to external services. > - A GitHub bot connection can add external contributors by username. > - The lookup sent an anonymous request even when the bot had an App installation. > - Anonymous requests share the server IP quota and can fail for a valid username. > - This pull request uses the selected bot installation for the lookup. > - It also gives users clear errors without exposing credentials or provider response text. ## Linked Issues or Issue Description **What happened?** The Access tab could reject a valid external contributor username with a generic GitHub error. The lookup did not use the connected bot's identity. **Expected behavior** The lookup uses the selected bot's active App installation. It returns the numeric user identity or a clear account, rate limit, or installation error. **Steps to reproduce** 1. Configure a GitHub review bot and open its Access tab. 2. Exhaust the server IP's anonymous GitHub quota. 3. Look up a valid external contributor username. 4. Observe the generic rejection even though the bot has an installation. The original provider HTTP status was not retained. Source inspection proves the anonymous request. The historical cause remains unconfirmed. **Paperclip version or commit** The defect is present at `eda2a03bfe5213ffef2fbbdefdf572be775f1e14`. **Deployment mode** Server deployment with an active GitHub App bot connection. ## What Changed - Pass the endpoint ID from the existing authorized lookup route. - Issue a short-lived installation token with metadata read permission. - Reject inactive connections and invalid installation IDs without an anonymous fallback. - Distinguish missing accounts, rate limits, and installation access failures. - Add 25 lookup tests and update the connector guide and both access maps. The GitHub management service owns the provider behavior. The shared route only passes its authorized endpoint ID. The request body and response shape stay the same. ## Verification - Passed: [full CI](https://github.com/paperclipai/paperclip/actions/runs/40535979115) on `38d1ebcebb08553f159b3b81ee1bb31d1fbbba8e`, including typecheck, build, server and workspace tests, Runner checks, serialized suites, eight E2E shards, and the final verification gate. - Passed: Greptile 5/5 for the same head, with no open review threads. - Passed: 25 lookup regression tests on the final test fixtures. - Passed: 91 tests across five GitHub service suites before the fixture-only change. - Passed: `node scripts/check-maps.mjs` and `git diff --check`. - The tests exercise actual GitHub request construction with provider response fixtures. They assert the installation identity, metadata-only token request, request count, and sanitized error details. - `pnpm build` and `pnpm -r typecheck` could not complete because this environment has no Cargo executable. - Two standalone server TypeScript attempts were killed. The second ran after the full suite was stopped, with a 5120 MiB Node heap limit. The 8 GiB container recorded two OOM kills. Neither attempt produced a typecheck verdict. - `pnpm test:run` was started, then interrupted after resource exhaustion. Its first server phase did not produce a final verdict. These local attempts remain incomplete. Full CI later passed for the same head. A live authenticated bot lookup remains unverified. - The initial frozen install stopped on an existing patch configuration mismatch. Installation then succeeded with lockfile writes disabled. No dependency or lockfile changes are included. - GitHub documents installation-token support for [Get a user](https://docs.github.com/en/rest/users/users#get-a-user) without extra user permissions. ## Risks - The lookup now requires an active bot connection and a saved installation ID. - GitHub rate limits can still occur. The error keeps the retry metadata and tells the user to retry. - No database migration or permission-policy change is included. - This PR does not prove that a deployment contains the fix. ## Model Used OpenAI Codex, GPT-6 family, with code editing, tool use, and test execution. The recovered implementation was assisted by `gpt-6.1-sol`. This session does not expose its exact model ID or context window limit. ## 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: Paperclip <noreply@paperclip.ing>
