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!

Walkthrough

Adds two GitHub Actions workflows: one auto-runs Claude-based code review on pull_request events; the other listens for “@claude” mentions on issues and reviews to run Claude Code. Both use anthropics/claude-code-action@v1, require CLAUDE_CODE_OAUTH_TOKEN, and operate with scoped read permissions and id-token write.

Changes

Cohort / File(s)	Change Summary
GitHub Actions: PR auto-review .github/workflows/claude-code-review.yml	Introduces “Claude Code Review” workflow triggered on pull_request (opened, synchronize). Checks out repo, runs anthropics/claude-code-action@v1 with a review prompt, constrained claude_args for gh operations, posts feedback as a PR comment. Permissions: contents/pull-requests/issues read; id-token write.
GitHub Actions: Mention-triggered assistant .github/workflows/claude.yml	Adds “Claude Code” workflow triggered on issue_comment, pull_request_review_comment, issues, pull_request_review. Conditional run only when “@claude” appears in relevant fields. Checks out repo and runs anthropics/claude-code-action@v1 with actions:read additional permission. Optional prompt/args commented.

Poem

I thump my paws at midnight’s cue,
Two workflows hop where none once grew—
One scans PRs with careful stare,
One answers pings of “@claude” flair.
With tokens tucked and actions light,
We comment, nibble, ship it right. 🥕✨
