type:audit type:review

Use to keep code MINIMAL and right-sized for AI coding agents. DO — keep an in-progress change minimal (reuse before adding, subtract, avoid the wrong abstraction, check blast radius). REVIEW — audit existing code or a repo for slop (duplication, dead code, over-engineering) and parallel-readiness (coupling, boundaries, gate coverage), then score it. DESIGN — shape right-sized boundaries and work-partitioning so many agents work in parallel, sequence a safe refactor, or explain a principle. Triggers on 'is this over-engineered', 'reduce the slop', 'audit our coupling/boundaries', 'structure this repo for parallel agents'. Do NOT use to wire enforcement gates/hooks/AGENTS.md (use harden-repo-for-coding-agents), for developer API/SDK/CLI surfaces (use dx-audit / dx-design), for product UX (use ux-audit / ui-design), or to tighten prose (use writing-audit).

Keep code minimal and right-sized for AI coding agents — anti-slop in the small, modular boundaries in the large. Provenance lives in skill.json; this file is runtime routing only.
