Triggers: quality-assurance, skills, optimization, tool-use, performance-metrics Evaluate and improve Claude skill quality through auditing.

Triggers: skill audit, quality review, compliance check, improvement suggestions, token usage analysis, skill evaluation, skill assessment, skill optimization, skill standards, skill metrics, skill performance

Use when: reviewing skill quality, preparing skills for production, auditing existing skills, generating improvement recommendations, checking compliance with standards, analyzing token efficiency, benchmarking skill performance

DO NOT use when: creating new skills from scratch - use modular-skills instead. DO NOT use when: writing prose for humans - use writing-clearly-and-concisely. DO NOT use when: need architectural design patterns - use modular-skills.

Skills Evaluation and Improvement

Overview

Analyze and improve Claude skills. Tools audit skills against quality standards, measure token usage, and generate improvement recommendations.

Tools

The evaluation process uses skills-auditor for structural analysis and improvement-suggester for prioritized fixes. compliance-checker validates standards, tool-performance-analyzer measures tool patterns, and token-usage-tracker monitors context efficiency.

What It Is

Evaluates and improves existing skills by running quality assessments, performance analysis, and generating improvement plans.

Quick Start

Basic Skill Audit

# Run detailed audit of all skills
python scripts/skills_eval/skills_auditor.py --scan-all --format markdown

# Audit specific skill
python scripts/skills_eval/skills_auditor.py --skill-path path/to/skill/SKILL.md

# Or use Makefile:
make audit-skill PATH=path/to/skill/SKILL.md
make audit-all

Verification: Verify build configuration with make --dry-run.

Skill Analysis

# Deep analysis of single skill
python scripts/skill_analyzer.py --path path/to/skill/SKILL.md --verbose

# Check token usage
python scripts/token_estimator.py --file path/to/skill/SKILL.md

# Or use Makefile:
make analyze-skill PATH=path/to/skill/SKILL.md
make estimate-tokens PATH=path/to/skill/SKILL.md

Verification: Verify build configuration with make --dry-run.

Generate Improvements

# Get prioritized improvement suggestions
python scripts/skills_eval/improvement_suggester.py --skill-path path/to/skill/SKILL.md --priority high

# Check standards compliance
python scripts/skills_eval/compliance_checker.py --skill-path path/to/skill/SKILL.md --standard all

# Or use Makefile:
make improve-skill PATH=path/to/skill/SKILL.md
make check-compliance PATH=path/to/skill/SKILL.md

Verification: Verify build configuration with make --dry-run.

Typical Workflow

1. Discovery: Run make audit-all to find and audit all skills
2. Analysis: Use make audit-skill PATH=... for specific skills
3. Deep Dive: Run make analyze-skill PATH=... for complexity analysis
4. Improvements: Generate plan with make improve-skill PATH=...
5. Compliance: Verify standards with make check-compliance PATH=...
6. Optimization: Check tokens with make estimate-tokens PATH=...

Common Tasks

Quality Assessment

# Detailed evaluation with scoring
./scripts/skills-auditor --scan-all --format table --priority high

# Detailed analysis of specific skill
./scripts/improvement-suggester --skill-path path/to/skill/SKILL.md --priority all --format markdown

Verification: Verify availability with --help.

Performance Analysis

# Token usage and efficiency
./scripts/token-usage-tracker --skill-path path/to/skill/SKILL.md --context-analysis

# Advanced tool performance metrics
./scripts/tool-performance-analyzer --skill-path path/to/skill/SKILL.md --metrics all

Verification: Verify availability with --help.

Standards Compliance

# Validate against Claude Skills standards
./scripts/compliance-checker --skill-path path/to/skill/SKILL.md --standard all --format summary

# Auto-fix common issues
./scripts/compliance-checker --skill-path path/to/skill/SKILL.md --auto-fix --severity high

Verification: Verify availability with --help.

Improvements and Optimization

# Generate prioritized improvement plan
./scripts/improvement-suggester --skill-path path/to/skill/SKILL.md --priority critical,high

# Benchmark performance
./scripts/token-usage-tracker --skill-path path/to/skill/SKILL.md --benchmark optimization-targets

Verification: Verify availability with --help.

Evaluation Framework

Quality Metrics Overview

The framework evaluates skills on weighted dimensions: structure compliance and content quality (20 points each), token efficiency and activation reliability (15 points each), and remaining points for tool integration, trigger isolation, and enforcement language.

Scoring System

Scores categorize quality: 91-100 (Excellent), 76-90 (Good), 51-75 (Basic), 26-50 (Below Standards), and 0-25 (Critical Issues).

Priority Levels

Improvements are prioritized to address the most critical issues first. Critical priority is assigned to security vulnerabilities, broken functionality, or missing required metadata. High priority concerns poor structure or incomplete documentation, while medium priority identifies missing best practices and optimization opportunities. Minor enhancements, such as formatting issues or improved examples, are categorized as low priority.
