Add Claude Code GitHub Workflow

[Bkm016]

🤖 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!

Review Findings

✅ Strengths

Security & Permissions:

• Proper use of CLAUDE_CODE_OAUTH_TOKEN secret instead of hardcoded tokens
• Minimal required permissions (contents: read, pull-requests: read, issues: read, id-token: write)
• Includes actions: read permission for CI integration in .github/workflows/claude.yml:26

Best Practices:

• Uses official anthropics/claude-code-action@beta action
• Proper checkout with actions/checkout@v4
• Well-structured conditional logic for triggering Claude
• Comprehensive trigger conditions covering multiple GitHub events

Documentation:

• Excellent inline comments explaining optional configurations
• Clear examples for customization scenarios
• Good separation of concerns between automated review and interactive workflows

🔍 Observations & Suggestions

1. Workflow Triggers (.github/workflows/claude.yml:15-19)
The conditional logic correctly handles multiple trigger scenarios:

if: |
  (github.event_name == 'issue_comment' && contains(github.event.comment.body, '@claude')) ||
  (github.event_name == 'pull_request_review_comment' && contains(github.event.comment.body, '@claude')) ||
  (github.event_name == 'pull_request_review' && contains(github.event.review.body, '@claude')) ||
  (github.event_name == 'issues' && (contains(github.event.issue.body, '@claude') || contains(github.event.issue.title, '@claude')))

2. Performance Considerations

• fetch-depth: 1 is optimal for reducing clone time
• Both workflows use the same runner (ubuntu-latest) consistently
• The automated review workflow includes path filtering options (commented out)

3. Optional Configurations
The workflows provide good examples for:

• Model selection (Claude Opus 4 vs Sonnet 4)
• Custom tool permissions
• Conditional reviews based on PR author
• File-specific review focus

💡 Minor Recommendations

1. Consider adding pull_request_target for external contributors:

   on:
     pull_request: [opened, synchronize]
     pull_request_target: [opened, synchronize]  # For external contributors

2. Environment-specific settings: Consider uncommenting and configuring the allowed_tools section in .github/workflows/claude.yml:53 to enable Claude to run project-specific commands like tests or linting.

3. Resource optimization: The commented path filters in .github/workflows/claude-code-review.yml:6-11 could be uncommented and customized based on your project structure to avoid unnecessary runs.

🔒 Security Assessment

• ✅ No hardcoded secrets or tokens
• ✅ Proper GitHub Actions secret usage
• ✅ Minimal permission principle followed
• ✅ No workflow injection vulnerabilities detected
• ✅ Safe use of GitHub context variables

📊 Test Coverage

While these are workflow configurations rather than application code, the setup provides a solid foundation for Claude to assist with test coverage improvements in future PRs.

Summary

This PR successfully implements Claude Code integration with two complementary workflows:

1. Automated reviews for all PRs with customizable prompts
2. Interactive Claude assistance via @claude mentions

The implementation follows GitHub Actions best practices, maintains security standards, and provides excellent configurability for future customization. The workflows are production-ready and will enhance the development process.
