Claude Code runs natively as a GitHub Action

Anthropic ships an official claude-code-action that runs Claude Code inside a GitHub Actions workflow. It can read your repo, write files, run commands, and commit, all triggered by a PR comment or a schedule.

The interesting part: it uses the same Claude Code you run locally, so your CLAUDE.md instructions carry over. The action respects the same permission model.

Immediate use cases I’m thinking about:

• Auto-generate TIL posts from GitHub Issues with a specific label
• Run a nightly review pass on open PRs
• Summarize recent commits and update a changelog

The main constraint is the Actions runner environment: you need to install any tools Claude Code will call (glow, rsync, etc.) as workflow steps before handing off to the action.
