Codebase Rules Generator

Generate lean, targeted Claude Code rules that precisely guide AI code generation.

Core Philosophy: Concise Over Comprehensive

Good rules are:

• Concise: One rule, one line when possible
• Targeted: Use paths: to scope rules to specific directories
• Actionable: Clear "do this" / "don't do that" guidance

Bad rules contain:

• Long code examples (move to referenced docs instead)
• Generic advice that applies to any project
• Redundant information already in source files
• Explanations of "why" (focus on "what" and "how")

Rule Writing Principles

1. Use paths: Frontmatter Aggressively

Every rule file that targets specific code areas MUST have paths: frontmatter:
