🤖 Installing Claude Code GitHub App

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!

The workflow grants read-only permissions (contents: read, pull-requests: read, issues: read), but the PR description states Claude will "create comments, branches, and commits". Verify whether the claude_code_oauth_token handles write operations independently, or if these permissions need to be elevated to write access (contents: write, pull-requests: write, issues: write) for Claude to function as described.

The workflow grants read-only permissions (pull-requests: read), which may be insufficient for Claude Code Review to post review comments on pull requests. Verify whether the claude_code_oauth_token handles write operations independently, or if pull-requests: write permission needs to be added.
