Scope

Foundry's public fork of the official Pi extension, with no upstream release publication. This is a focused Pi transport/package increment, not full Foundry integration-health or MVP acceptance.

  • Bound Context7 requests to a 12s timeout, 800-character control-free inputs, and a 128 KiB response; propagate Pi abort signals and cover refusal paths.
  • Keep the official Context7 endpoint and existing resolve-library-id / query-docs tools. No project data is sent by the tests; the live upstream-style query uses only public React documentation text.
  • Make upstream release automation inapplicable to 10krco/context7. The fork still lints/builds/typechecks the monorepo, but scopes Test to the consumed Pi package: the unaffected tools-ai-sdk suite requires upstream AWS Bedrock credentials (five failures with missing AWS_REGION on the earlier head). Skip upstream AWS/SDK integration steps on the fork. Add a required build job exercising the Git-subdirectory Pi package and packed resources.

Observations

  • Source at parent upstash/context7@e275a848a420e0d11c2822f61201ee005bfd1133; local package npm run typecheck and npm test: 9/9 (includes the upstream live public React resolve test); npm pack --dry-run --json contains the Pi extension, API and MIT license.
  • An unmodified parent-commit Git-subdirectory dependency installed in a disposable npm consumer without running lifecycle scripts. Its installed production dependency audit reported zero npm advisories; GitHub's broader monorepo vulnerability warning is not being dismissed as a Pi-package pass.
  • CI on this PR and independent review must be checked on the final head before merge. Foundry still needs separate real, fail-closed clean-profile health checks and privacy review; this PR does not activate the owner's Pi profile or make a publication.

📝 Summary

Summary by CodeRabbit

  • Improvements
    • Documentation searches can now be canceled while in progress and automatically time out after 12 seconds.
    • Requests reject blank, excessively long, or control-character queries, and responses are limited in size to help prevent oversized requests and results.
    • Error messages from failed requests are capped in length. If an error response cannot be parsed, a status-based message is shown instead.

Walkthrough

The Pi package API now validates inputs, limits request duration and response size, and accepts caller abort signals. GitHub Actions adds Pi package validation and restricts release and integration-test steps to the upstream repository.

Changes

Bounded Context7 API requests

Layer / File(s) Summary
Bounded API requests and tool signal forwarding
packages/pi/lib/api.ts, packages/pi/lib/tools/*, packages/pi/__tests__/api-bounds.test.ts
Search and context requests validate inputs, use a 12-second timeout, and limit response bodies to 128 KiB. Both tools forward optional abort signals. Tests cover request parameters, input and response limits, cancellation, and HTTP 503 handling.

GitHub Actions checks and repository guards

Layer / File(s) Summary
Pi package build and validation
.github/workflows/foundry-build.yml
A new workflow installs, typechecks, and tests the Pi package, then checks that a dry-run package archive contains three required files.
Release and integration-test conditions
.github/workflows/release.yml, .github/workflows/test.yml
The release job runs only in upstash/context7. AWS credential setup and SDK integration tests are restricted to that repository and its own pull requests. Forks run only the @upstash/context7-pi tests.

Merge Risk: ⚪ Minimal · up to aa955

The cancellation test does not have the reported race; no identified issue remains that should delay this change.

Security Architecture Review

Security architecture risk: 🔵 Low · up to aa955

The changes bound Context7 requests and restrict fork release and AWS integration paths. No new privileged or externally reachable path was identified. Final-commit CI results and the fork’s deployment context remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed request controls apply to both existing Pi tools’ calls to Context7; the inspected paths show no new endpoint or tool registration.

Security Findings and Attack Paths

  • observed — The range classified as a public entrypoint is a start method inside a test response stream, not a production caller.

Trust Boundaries and Controls

  • observed — Caller-controlled tool parameters cross into an outbound request only after input checks; caller cancellation and the package timeout govern the fetch, and the returned body is size-bounded.
  • observed — The fork release gate precedes npm authentication and publication steps. The Test workflow’s job-wide OIDC permission remains present even though its AWS credential step is gated.

Resilience and Maintainability Implications

  • observed — Each request constructs its own timeout signal and response reader. The reader completes normally or attempts cancellation and lock release on an incomplete read; no shared request state is shown.

Hardening Proposals

  • proposed — Consider limiting OIDC token permission to the upstream job that needs AWS credentials, rather than granting it throughout the Test job. The job-wide permission predates this change and is not an identified PR-introduced finding.

minimal, and validate.

Inline comments:
In @packages/pi/lib/api.ts:
- Line 63: Update parseErrorResponse to await boundedText(response) before
entering the try block, then parse the captured text inside it. This lets
body-read cancellation and timeout errors propagate while retaining the existing
handling for JSON parse failures.
