Claude Code In CI And GitHub Actions

Claude Code can run inside GitHub Actions or any CI runner — for code review, automated fixes, or release scaffolding. The discipline is in the permission scoping, not the prompt.

What CI use cases look like

Once Claude Code can run headlessly, you can wire it into pipelines. Three durable patterns: PR-time code review (it comments on the diff), nightly maintenance (it bumps deps, runs migrations, opens PRs), and fix-on-failure (when CI breaks, an agent attempts a repair and pushes a fix branch).

The minimal Action

name: Claude Code Review
on:
  pull_request:
    types: [opened, synchronize]

jobs:
  review:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write
      contents: read
    steps:
      - uses: actions/checkout@v4
      - name: Run Claude Code review
        env:
          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
        run: |
          npx -y @anthropic-ai/claude-code \
            --headless \
            --task 'Review the diff in this PR. Comment on issues using the GitHub API. Skip nits.'A skeleton review Action. The exact CLI flags drift; pin the version and check the docs page on setup day.

The permission scoping rules

Use the smallest permissions that work — read-only for review, write only for fix-on-failure
Never give CI an API key with billing rights you can't tolerate burning
Set per-job spend caps if available; protect the budget from runaway loops
Run on PRs from forks with extra restrictions — don't expose secrets to untrusted PRs
Always require a human reviewer to merge — the agent comments, the human approves

Cost discipline

An agent in CI can run on every push, every PR update, every nightly trigger. Token costs add up fast. Cap aggressively: only review the diff, not the whole repo; only re-run when meaningful changes happen; throttle nightly tasks to once per night, not per branch.

Use case	Permissions	Cost discipline
PR review	Read code, comment on PR	Diff-only context
Nightly dep bumps	Write code, open PR	Once per night
Fix-on-failure	Write code, push branch	Cap retries; per-job spend cap
Doc generation	Read code, open PR with docs	Trigger on releases only

Apply: build one CI workflow

Pick a low-stakes use case (review nits on PRs)
Wire up a workflow with read-only permissions
Run it for a week; observe the comments
Tune the prompt to skip the noise you don't want
Only graduate to write permissions after you trust the read-only behavior

The big idea: Claude Code in CI is powerful and dangerous in equal measure. Scope tight, cap spend, keep humans in the merge loop.
