Warning

Rate limit exceeded

@don-petry has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 2 minutes and 31 seconds before requesting another review.

Your organization is not enrolled in usage-based pricing. Contact your admin to enable usage-based pricing to continue reviews beyond the rate limit, or try again in 2 minutes and 31 seconds.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.

Summary

GitHub Actions Workflow .github/workflows/claude.yml

New workflow "Claude Code" triggers on pull_request (opened, reopened, synchronize), issue_comment, and pull_request_review_comment. Job runs on ubuntu-latest with 60-minute timeout, minimal repo permissions and id-token: write. For comment events, executes only when comment body contains @claude and commenter author_association is OWNER, MEMBER, or COLLABORATOR. Runs anthropics/claude-code-action@v1 using secrets.CLAUDE_CODE_OAUTH_TOKEN as the Anthropic API key.

11-22: Consider adding concurrency to avoid duplicate in-flight reviews.

Line 11–Line 22 can queue multiple runs during rapid synchronize events. A concurrency group with cancel-in-progress: true will reduce cost/noise.

runs-on) add a concurrency block that defines a stable group identifier (e.g.,
using github.workflow and either github.event.pull_request.number or
github.ref/sha) and set cancel-in-progress: true so new runs cancel previous

with a pinned commit SHA (e.g., "anthropics/claude-code-action@<commit-sha>") to
prevent automatic updates; locate the uses: anthropics/claude-code-action@v1

a full ref like refs/heads/<branch>@<sha>) and commit the change.
