When should I use a Rule instead of a Skill?

Use Rules for advisory constraints that Claude should follow automatically when working with files. Use Skills for reference material or specific procedures that should be invoked on-demand.

What is the recommended structure for a Claude Rule?

A rule should include a YAML frontmatter block with path patterns, followed by concise, declarative constraints that state what should or shouldn't be done, ideally kept under 30 lines.

What is the difference between Rules and CLAUDE.md?

Rules are scoped to specific file patterns (like .ts or .test.ts files) and load only when relevant, whereas CLAUDE.md provides universal project context loaded for every session.

How do I make a rule apply to the entire project?

To create a global rule, simply omit the 'paths' section in the rule file's frontmatter. This ensures the constraint is loaded for every session regardless of the file being edited.

Provides comprehensive guidance for creating declarative, file-scoped constraints that Claude follows automatically during the development process.

The Rules Authoring skill is a specialized meta-guide designed to help developers craft effective .claude/rules/ files. It enables the creation of project-specific constraints—such as coding conventions, quality standards, or security protocols—that are automatically applied based on file path patterns. By following the declarative patterns outlined in this skill, users can ensure Claude adheres to unique project requirements without the need for manual prompts, leading to higher consistency and reduced technical debt across the codebase.
