What is Claude Code?

Claude Code is an AI coding agent that can help with:

• Bug fixes and improvements
• Documentation updates
• Implementing new features
• Code reviews and suggestions
• Writing tests
• And more!

How it works

Once this PR is merged, we'll be able to interact with Claude by mentioning @claude in a pull request or issue comment.
Once the workflow is triggered, Claude will analyze the comment and surrounding context, and execute on the request in a GitHub action.

Important Notes

• This workflow won't take effect until this PR is merged
• @claude mentions won't work until after the merge is complete
• The workflow runs automatically whenever Claude is mentioned in PR or issue comments
• Claude gets access to the entire PR or issue context including files, diffs, and previous comments

Security

• Our Anthropic API key is securely stored as a GitHub Actions secret
• Only users with write access to the repository can trigger the workflow
• All Claude runs are stored in the GitHub Actions run history
• Claude's default tools are limited to reading/writing files and interacting with our repo by creating comments, branches, and commits.
• We can add more allowed tools by adding them to the workflow file like:

allowed_tools: Bash(npm install),Bash(npm run build),Bash(npm run lint),Bash(npm run test)

There's more information in the Claude Code action repo.

After merging this PR, let's try mentioning @claude in a comment on any PR to get started!

PR Review: Add Claude Code GitHub Workflow

Summary

This PR shows 0 file changes according to GitHub. The workflow files already exist in the repository.

Review of Existing Workflows

I reviewed .github/workflows/claude.yml and .github/workflows/claude-code-review.yml:

Positive Observations

• Security: OAuth token properly stored as secret, minimal permissions granted
• Structure: Clean trigger configuration, proper use of claude-code-action@v1
• Documentation: Comprehensive PR description with security notes

Recommendations

1. Missing Changes: This PR shows 0 additions/deletions. Verify the base branch is correct or if changes are already merged.

2. Performance: Consider adding file path filters to claude-code-review.yml to avoid reviewing non-code files (lines 7-11 are commented).

3. Documentation: Add Claude Code integration section to CLAUDE.md explaining both workflows.

4. Testing: Test the @claude mention trigger and verify the auto-review workflow runs.

5. Concurrency: Consider adding concurrency control to prevent multiple simultaneous reviews.

Security Audit

No security concerns - secrets managed properly, permissions follow least privilege, tool access restricted appropriately.

Conclusion

Workflows are well-structured but this PR appears empty. Please clarify what files are being modified.
