Claude Code in CI/CD

Claude Code in CI/CD means invoking Claude Code in a headless, non-interactive mode — for example triggered by a pull request, an issue label, or a scheduled job — to triage failures, draft fixes, review diffs, or update dependencies without a human at the keyboard. The value is scale; the danger is that an agent now has a path to change your codebase automatically.

The controlling principle is least privilege plus a human gate. The agent should run with a scoped token, write to a branch and open a pull request rather than pushing to a protected default branch, and execute any code it generates inside a sandboxed environment so a hallucinated shell command cannot touch production or exfiltrate secrets. Branch protection rules keep a required human review between the agent's output and merge.

Good pipeline design also makes the agent's work observable and reversible: every autonomous change is a reviewable diff, runs the full test and lint suite, and can be reverted like any other commit. "The agent opened a PR that a human approved" is the exam-correct pattern; "the agent pushed straight to main" is the trap.
