What problem does it solve? CLAUDE.md files often become stale, sparse, or filled with generic advice, leaving Claude Code without accurate project context. This Skill scans a repository for all CLAUDE.md files, scores them against a structured quality rubric, and applies targeted improvements after user approval. ## Core Features & Use Cases - Repository-wide discovery: Finds project root, local override, global, package-level, and nested CLAUDE.md files automatically. - Scored quality reports: Evaluates each file across six weighted criteria (commands, architecture, patterns, conciseness, currency, actionability) and assigns letter grades. - Targeted updates with diffs: Proposes minimal, project-specific additions shown as diffs, then applies them with the Edit tool only after confirmation. - Use Case: After a major refactor, run an audit to catch broken build commands and outdated architecture notes across a monorepo's CLAUDE.md files, then update them in one pass. ## Quick Start Audit all CLAUDE.md files in this repository and show me a quality report with recommended improvements.
