What problem does it solve? Codebase audits often produce vague advice that dies in a chat transcript. This Skill surveys a repository like a senior advisor, vets every finding against the actual code, and produces prioritized, fully self-contained implementation plans that a separate, less capable model or agent can execute without any context from the original session. ## Core Features & Use Cases - Read-only codebase audit: Surveys correctness, security, performance, test coverage, tech debt, dependencies, DX, docs, and product direction using parallel read-only subagents, with strict rules against modifying source code. - Self-contained handoff plans: Writes plans to .scratch/plans/ with inlined code excerpts, exact verification commands, scope boundaries, STOP conditions, and machine-checkable done criteria so an executor with zero context can succeed. - Execution and follow-through: Supports invocation variants like quick/deep effort levels, branch diffs, next roadmap audits, execute <plan> with an isolated-worktree executor and tech-lead review, reconcile for stale plans, and --issues to publish plans as GitHub issues. - Use Case: Point it at a legacy service and ask for a security audit; it returns a vetted findings table, then writes ordered plans (e.g., add characterization tests before refactoring) that a cheaper executor agent implements in a worktree while it reviews the diff. ## Quick Start Ask the agent to audit this repository for improvement opportunities and write prioritized implementation plans for the top findings.
