Autonomous, safety-first pull request review-and-merge pass over a repository with many open PRs, on any tech stack (Node, PHP, Go, Python, Rust, Ruby, Java/Kotlin, Android, monorepos). Reviews each PR's full diff, classifies it CLEAN / FIXABLE / BLOCKED, fixes small issues, merges safe PRs one at a time, verifies the default branch still builds and passes tests, and produces a final report. Use this skill whenever the user mentions a backlog of pull requests, asks to review and merge PRs, clear the PR queue, "merge what's safe", check that nothing breaks after merging, or hands PR handling to an agent while they are away, even if they don't say "skill" or name a specific stack. Supports "review only" / "dry run" mode.
