Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

📝 WalkthroughWalkthroughAdds a composite Reviewdog GitHub Action that validates Dagger diagnostic manifests, safely reads report files, and publishes pull-request annotations. It includes pinned setup, behavior tests, fixtures, workflow checks, and documentation. ChangesReviewdog action
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The action currently exposes the GitHub token to helper commands and reopens report paths after validation, which can permit token disclosure or bypass file-safety checks in a mutable workspace. These are high-impact security risks that should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@actions/reviewdog/run.sh`:
- Around line 90-105: Update the report validation and publication flow around
report_path and the later Reviewdog invocation to open each validated report
immediately, validate the opened descriptor via /proc/self/fd against the report
root, regular-file, and size constraints, and retain descriptors only after all
reports pass validation. Use the stored descriptors rather than reopening
pathnames during publication, then close them after Reviewdog completes.
- Around line 14-17: In the script initialization around manifest and token
validation, copy the token into the local non-exported token variable and unset
REVIEWDOG_GITHUB_API_TOKEN before any external command runs. Update only the
report-publishing reviewdog invocations to pass
REVIEWDOG_GITHUB_API_TOKEN="$token" inline, while leaving realpath, stat, jq,
and reviewdog -list without the token.
