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

• Scan .claude/rules/ for all .md files (including subdirectories)

• Validate YAML frontmatter syntax and fields

• Analyze glob patterns for correctness and specificity

• Assess content quality (actionable, concise, non-conflicting)

• Check organization (naming, structure, symlinks)

• 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
