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.mdfiles (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 |

Exit Criteria
- [ ] Every
.mdfile under.claude/rules/(including subdirectories) receives a quality score (0-100) with per-category breakdown across the five dimensions. - [ ] YAML frontmatter syntax errors and unquoted glob patterns are listed as blocking findings before any score is reported.
- [ ] Rules using Cursor-specific fields (
alwaysApply,globs) are flagged as non-compliant with the expected Claude Code schema. - [ ] Any rule scoring below 26 (Critical tier) is reported with at least one concrete corrective action, not just a score.
