Claude Code hooks — CCA-F Exam Prep

MYSTERYA CI/CD pipeline dashboard. Every build is green. But a developer notices something strange: the last 20 Claude Code commits all have perfect lint scores, no type errors, and updated changelogs. Nobody on the team has been running these checks manually. Terminal logs scrolling, green check marks.

Every Claude Code commit is perfect. Linted. Type-checked. Changelog updated. Nobody is doing it manually.

Before last week, half the commits failed lint. Type errors slipped through. The changelog was always out of date. Then the tech lead changed something, and now every commit is clean.
