Where should shared project rules be stored?

Project-specific rules should be stored in .claude/rules/ within your repository root so they can be version-controlled and shared with your entire team.

What is the difference between a rule and a skill?

Rules provide passive guidance and constraints (directives), while skills provide active workflows, scripts, and new capabilities for Claude to execute.

What are Claude Code rules?

Rules are markdown files stored in the .claude/rules/ directory that provide domain-specific instructions, coding standards, and best practices for Claude to follow during a session.

Can I test if a rule is actually working?

Yes, the rule-creator includes a robust evaluation workflow that runs comparison tasks with and without your rules to measure impact and accuracy.

How does this skill optimize token usage?

The skill audits rules for redundancy and helps you implement path-targeted frontmatter, ensuring that specific instructions are only loaded when relevant files are being edited.

Developer Tools

Automates the creation, auditing, and optimization of custom project rules to guide Claude's coding behavior effectively.

Claude Rule Architect is a specialized skill designed to manage the full lifecycle of Claude Code project rules. It enables developers to define coding standards, enforce project-specific patterns, and audit existing rules for token efficiency and semantic overlap. By providing a structured workflow for rule creation, validation, and evaluation, it ensures that Claude remains highly performant and context-aware without bloating the conversation budget. This tool is essential for teams looking to maintain consistent AI-driven development practices across complex codebases.
