Overview

This skill evaluates Claude Code rules in .claude/rules/ directories against quality standards. It validates YAML frontmatter, glob pattern syntax, content quality, and directory organization. Rules files support path-scoped conditional loading via paths frontmatter and unconditional rules (no paths field).

Key validations: YAML syntax errors, unquoted glob patterns, Cursor-specific fields (alwaysApply, globs), overly broad patterns, content verbosity, and naming conventions.

Quick Start

# Evaluate rules in current project
/rules-eval

# Evaluate specific directory
/rules-eval .claude/rules/

# Detailed analysis with recommendations
/rules-eval --detailed

Evaluation Workflow

1. Scan .claude/rules/ for all .md files (including subdirectories)
2. Validate YAML frontmatter syntax and fields
3. Analyze glob patterns for correctness and specificity
4. Assess content quality (actionable, concise, non-conflicting)
5. Check organization (naming, structure, symlinks)
6. Measure token efficiency and redundancy

Scoring

| Category | Points | Focus | |----------|--------|-------| | Frontmatter Validity | 25 | YAML syntax, required fields, correct field names | | Glob Pattern Quality | 20 | Syntax, specificity, quoting | | Content Quality | 25 | Actionable, concise, non-conflicting | | Organization | 15 | Naming, structure, symlink usage | | Token Efficiency | 15 | Rule size, redundancy detection |

| Score | Level | |-------|-------| | 91-100 | Excellent - Production-ready | | 76-90 | Good - Minor improvements possible | | 51-75 | Basic - Needs optimization | | 26-50 | Below Standards - Significant issues | | 0-25 | Critical - Invalid or broken rules |
