What problem does it solve? Root instruction files such as AGENTS.md often grow bloated with details that belong in documentation, or miss essential rules entirely. This Skill audits or drafts root agent instructions so they stay short, durable, and routing-focused. ## Core Features & Use Cases - Structured Audit: Reads AGENTS.md (falling back to CLAUDE.md, README.md, and docs), counts lines against a 50-200 line target, and classifies content as essential rules versus material that should move elsewhere. - Standard Target Shape: Provides a canonical section outline covering Harness, Project Summary, Quick Start, Verification, State Files, Hard Rules, and Links. - Safe Editing Workflow: Produces a structured audit report with a proposed replacement outline, and requires approval before writing or trimming anything. - Use Case: When bootstrapping a new project or cleaning up an overgrown AGENTS.md, run the audit to identify which rules to preserve, which details to relocate into docs or skills, and what is missing. ## Quick Start Audit my AGENTS.md file and propose a trimmed 50-200 line version that keeps the essential project rules.
