What problem does it solve? Code and design reviews often miss edge cases, weak test assertions, and unstated assumptions, letting defects slip through each stage of the software lifecycle. This Skill enforces multi-stage adversarial audits of specifications, plans, RED tests, and code worktrees so issues are caught before merge. ## Core Features & Use Cases - Four Review Gates: Routes between spec-review, plan-review, test-review, and code-review modes, each with its own checklist and verdict contract (APPROVE / REJECT / NEEDS_REVISION). - Isolated Worktree Audits: The resolve_branches.py script fetches remote branches or PR heads, creates managed git worktrees, and guards against re-reviewing unchanged commit SHAs. - External Reviewer Orchestration: Supports living review branches with per-reviewer file isolation, tamper tripwires, signal scorecards, and convergence gates for asynchronous external agents. - Use Case: Before merging a feature branch, run an adversarial code review that diffs the branch against the integration baseline inside a disposable worktree, runs the test suite, and produces a copy-paste action plan for PR comments. ## Quick Start Ask the agent to run an adversarial review on your feature branch and select the target branch when prompted.
