FAQPage Schema
How do I validate CLAUDE.md frontmatter and structure in my project?

To set up CLAUDE.md for a monorepo, use lazy-loading rules and subdirectory CLAUDE.md files to manage loading order. This skill scans repository layouts to enforce rules directories and reduce configuration drift across nested project paths.

What is the best way to organize CLAUDE.md files across a monorepo?

Organizing CLAUDE.md files across a monorepo involves placing subdirectory CLAUDE.md files alongside lazy-loading rules at the root. This skill guides structure and cross-tool compatibility to maintain consistent behavior across all nested projects.

How do I scan my repository for CLAUDE.md loading order and anti-patterns?

You can scan your repository for CLAUDE.md loading order and anti-patterns by running the provided bash scan script with your project path. It audits file layouts, rules directories, and detects common structural issues.

Do I need specific dependencies to run CLAUDE.md validation scripts?

You do not need specific dependencies to run CLAUDE.md validation scripts. The package provides standalone bash and Python scripts requiring only standard environments to scan and validate your CLAUDE.md files.

Why does my CLAUDE.md configuration drift between different tools?

Your CLAUDE.md configuration drifts between tools due to inconsistent file organization and frontmatter errors. This skill reviews and optimizes CLAUDE.md for cross-tool compatibility, enforcing section organization and anti-pattern checks to prevent drift.
