Add Claude Code GitHub Workflow

[manupastorr]

🤖 Installing Claude Code GitHub App

This PR adds a GitHub Actions workflow that enables Claude Code integration in our repository.

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!

Code Review Complete ✅

Review Checklist:

• Read and analyze both workflow files
• Evaluate workflow structure and triggers
• Check security best practices
• Assess performance considerations
• Look for potential bugs or issues
• Provide recommendations and feedback

Overall Assessment

Both workflow files are well-structured and follow GitHub Actions best practices. The code quality is good with comprehensive configuration options and proper security measures.

Detailed Findings

✅ Code Quality & Best Practices

• Good structure: Both workflows follow consistent YAML formatting and GitHub Actions conventions
• Comprehensive configuration: Excellent use of commented examples for customization
• Action versions: Using latest stable versions (actions/checkout@v4, anthropics/claude-code-action@beta)
• Clear naming: Descriptive job names and step names

✅ Security

• Proper token handling: CLAUDE_CODE_OAUTH_TOKEN correctly stored in GitHub secrets
• Minimal permissions: Both workflows use principle of least privilege with specific permissions:
  • contents: read
  • pull-requests: read
  • issues: read
  • id-token: write
  • actions: read (only in claude.yml)
• No hardcoded secrets: All sensitive data properly externalized

✅ Performance Considerations

• Efficient checkout: fetch-depth: 1 reduces clone time and network usage
• Conditional execution: claude.yml has proper if conditions to prevent unnecessary runs
• Targeted triggers: Workflows only run when needed (PR events, @claude mentions)

⚠️ Minor Issues & Recommendations

1. Workflow Trigger Overlap (.github/workflows/claude-code-review.yml:4-5)

   • The review workflow runs on all PRs, but the main claude workflow also handles PR review comments
   • Consider adding exclusion logic or making the review workflow more targeted

2. Beta Version Usage (both files)

   • Both workflows use anthropics/claude-code-action@beta
   • Consider pinning to specific version tags for better stability once available

3. Missing Error Handling

   • No explicit error handling or failure notifications
   • Consider adding steps to handle API failures gracefully

4. Documentation Gap

   • No inline documentation about the id-token: write permission requirement
   • Consider adding comments explaining why each permission is needed

📋 Suggestions for Enhancement

1. Add workflow status badges to README
2. Consider adding timeout settings for long-running reviews
3. Add workflow concurrency controls to prevent overlapping runs:

   concurrency:
     group: claude-${{ github.ref }}
     cancel-in-progress: true

🧪 Test Coverage

• No test coverage for the workflows themselves (expected for GitHub Actions)
• Good: The workflows don't modify critical code paths
• Suggestion: Consider adding integration tests for the Claude Code action in a separate repository

Final Verdict

✅ Approved - These workflows are production-ready with solid security practices and good structure. The minor issues are suggestions for improvement rather than blocking concerns.

Bug: Claude Workflow Permissions Mismatch

The anthropics/claude-code-action in both .github/workflows/claude.yml and .github/workflows/claude-code-review.yml requires write permissions for pull requests and issues to post feedback. However, the workflows explicitly set pull-requests: read and issues: read. This read-only configuration, which overrides default GITHUB_TOKEN scopes, prevents Claude from creating PR reviews or issue/PR comments, resulting in "Resource not accessible by integration" (HTTP 403) errors.
