Catch dead Claude rules before they silently do nothing.

CLI that verifies .claude/rules/*.md paths: globs actually match files in your project.

# One-off
npx claude-rules-doctor check --root .

# Or install globally
npm install -g claude-rules-doctor
rules-doctor check --root .

Claude rules with paths: frontmatter can silently fail if:

• The glob pattern doesn't match any files
• File paths changed after the rule was created
• Typos in glob patterns

This tool scans all your rules and tells you which ones are "dead" (not applying to any files).

rules-doctor check

rules-doctor check --ci

rules-doctor check --json

rules-doctor check --verbose

rules-doctor check --root /path/to/project

• ✅ OK — Rule is global (no paths) or paths match files
• ⚠️ WARNING — Rule misconfigured: invalid YAML frontmatter, empty paths array, invalid types in paths, or invalid glob patterns
• ❌ DEAD — Paths specified, but 0 files match

A rule gets WARNING status when:

• Invalid YAML in frontmatter
• Empty paths array (paths: [])
• Non-string values in paths (numbers, booleans, null)
• Invalid glob patterns
