What problem does it solve? Codebase audits often produce vague advice that dies in a chat transcript, and handing improvement work to a fresh agent without context leads to broken or out-of-scope changes. This Skill surveys a repository as a read-only senior advisor, vets every finding against the actual code, and writes fully self-contained implementation plans that a separate executor model can carry out, verify, and be reviewed against. ## Core Features & Use Cases - Multi-category audit: Fans out read-only analysis across correctness, security, performance, test coverage, tech debt, dependencies, DX, docs, and product direction, with quick/standard/deep effort levels and parallel subagent support. - Self-contained handoff plans: Writes prioritized plan files under plans/ with inlined code excerpts, exact verification commands, scope boundaries, STOP conditions, drift checks, and a status index, so an executor with zero prior context can succeed. - Execution loop: Variants like execute <plan> dispatch an isolated-worktree executor subagent and review its diff like a tech lead, while reconcile keeps the plan backlog current and --issues publishes plans as GitHub issues. - Use Case: Point it at a TypeScript monorepo and ask for a security-focused audit; it maps the repo, verifies each finding against the source, presents a leverage-ranked table, and writes plans another agent can implement and test independently. ## Quick Start Ask the assistant to audit this repository with the improve skill and turn the top findings into executable plans.
