What problem does it solve? Claude Code configuration files (CLAUDE.md, agent definitions, skills) accumulate stale, redundant, or vague instructions over time as the platform evolves. This Skill audits your project-level .claude/ directory against current official documentation and community best practices, then proposes evidence-backed edits you approve individually. ## Core Features & Use Cases - Evidence-based auditing: A Researcher agent fetches Anthropic docs and community sources, and every proposed change must cite a quoted source — no speculation from model knowledge. - Six classification labels: Instructions are flagged as REMOVE, UPDATE, ADD, RESTRUCTURE, IMPROVE, or KEEP, with gap analysis against a best-practices checklist. - Approval-gated edits: Nothing is written until you approve each item; a Writer, prompt engineer, and change reviewer then apply and verify the exact approved diff. - Use Case: Your CLAUDE.md has grown bloated over months. Run the audit to discover that several "always do X" rules should be PostToolUse hooks, one model ID is deprecated, and three new settings keys make old prose instructions redundant. ## Quick Start Ask the assistant to audit and optimise my CLAUDE.md and agent configs for current Claude Code best practices.
