What are Claude Code rules?

Rules are markdown files stored in the .claude/rules/ directory that provide specific instructions, best practices, and constraints for Claude to follow when performing tasks in your project.

Does Rules Builder validate my configuration?

Yes, the skill automatically validates your rule frontmatter against a JSON schema to ensure fields like paths, priority, and description are correctly formatted.

Can I apply rules to specific files only?

Yes, Rules Builder helps you configure path-specific rules using glob patterns, ensuring that instructions for things like API endpoints or CSS only trigger when relevant files are modified.

Can project rules override global rules?

Yes, while global rules load first, project-level rules load afterward and can be used to override or refine global settings for specific codebases.

Where are global rules stored?

Global rules are stored in your home directory at ~/.claude/rules/ and apply to every project you open with Claude, allowing for consistent personal preferences.

Productivity & Workflow

Manages modular Claude Code rules through interactive guided elicitation to standardize project conventions and personal workflows.

About

Rules Builder is an interactive skill designed to simplify the management of Claude Code rules across both local projects and global user-level configurations. It guides users through creating, editing, and organizing rule files in .claude/rules/ using specific glob patterns and YAML frontmatter. By providing structured elicitation, it helps developers define path-specific constraints, enforce coding standards, and maintain consistent behavior for Claude throughout their development environment, ensuring the AI agent adheres to the exact requirements of different domains like frontend, backend, or security.
