20. GitHub Actions

Up to now, Claude Code works when you are at the terminal. But your project lives on GitHub — and things happen there even when you are not around: PRs are opened, code is pushed, issues are created. GitHub Actions lets Claude Code react to these events automatically.

Developers know this as CI/CD — but the concept is simple: when something happens in the repository, an action runs. The practical result: every PR gets an automatic code review, and anyone on the team can ask Claude for help directly in GitHub comments — no terminal required.

#What you need

Before starting, confirm you have:

• A GitHub repository (if you followed section 12, you already have one)
• Claude Code subscription (Pro or Max) or an Anthropic API key
• Admin access to the repository (to install the GitHub App and add secrets)

The setup has three steps: install the app, add the authentication token, and create the workflow files. Each step takes less than two minutes.
