improve-my-codebase

Use when the user wants a prioritized improvement report across an entire codebase or a scoped subset. Orchestrates the existing audit skills (Parnas, Ousterhout, Hickey, Martin, Evans, Rams, etc.) in parallel and produces a ranked, per-file report. Trigger on "/improve-my-codebase", "audit my codebase", "what should I improve", "review the whole repo", or scoped variants.
