Tutorial: Wire Claude Code Into GitHub Actions, GitLab CI and Jenkins

Once the agent is trustworthy enough on your repo, put it in CI. Triage failing tests, regenerate snapshots, open cleanup PRs, all without human involvement. Here are three ready-to-use pipeline recipes.

GitHub Actions

Use `anthropics/claude-code-action` with an `ANTHROPIC_API_KEY` secret. The action runs in headless mode against the PR diff. Output becomes an inline review comment.

GitLab CI

Stage with `image: node:20`, install `@anthropic-ai/claude-code`, run in headless mode with `--print` flag. Pipe output to `glab mr note`. Works for self-hosted runners too.

Jenkins

Declarative pipeline with a `nodejs` tool, shell stage that calls `claude --print`, and `archiveArtifacts` for the transcript. Pair with a Jenkins shared library to reuse across dozens of pipelines.

Frequently asked questions

Does running headless skip hooks?

No. Hooks run the same way. That is why CI is a safe place for the agent: the same guardrails that hold locally hold in CI.
