Automate Code Reviews on Every PR with Claude Code + GitHub Actions

Every pull request is a potential quality gate. The problem: code reviews take time, reviewers get fatigued, and security checks are often skipped under deadline pressure. With Claude Code integrated into GitHub Actions, every PR gets: A 5-axis code review (design, readability, performance, security, testability) A secret scan (leaked API keys, tokens) A dependency CVE check All automatically, before a human reviewer even opens the PR.
