What problem does it solve? Iterative code review cycles waste time because automated reviewers and human reviewers find issues one at a time across multiple rounds. This Skill front-runs that process by catching the same classes of issues locally before a PR is ever opened or updated. ## Core Features & Use Cases - Diff-Aware Full-File Audit: Resolves the authoritative base branch, maps every changed file, then reads each file completely (not just the diff) to catch security gaps, logic errors, dead code, and inconsistencies. - Stack-Adaptive Tool Checks: Detects TypeScript, Node, Bash, and Python stacks and runs the right validators (tsc, ESLint, tests, ShellCheck, Ruff, Mypy), treating every tool failure as blocking. - Reviewer Simulation & Pre-Push Checklist: Asks the exact questions a reviewer would ask, scans for leftover debug statements and staged secrets, and produces a structured READY FOR REVIEW or BLOCKED report. - Use Case: Before running gh pr create on a feature branch, invoke the preflight to run type checks, lint, tests, and a full-file audit of your changes, then fix findings locally so the automated reviewer finds nothing. ## Quick Start Ask the agent to run the PR preflight check on the current branch before opening a pull request.
