Evaluate and improve Claude skill quality through auditing. Triggers: quality-assurance, skills, optimization, tool-use, performance-metrics, 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, or auditing existing skills. Do not use when creating new skills (use modular-skills) or writing prose (use writing-clearly-and-concisely). Use this skill before shipping any skill to production.

## Overview

This framework audits Claude skills against quality standards to improve performance and reduce token consumption. Automated tools analyze skill structure, measure context usage, and identify specific technical improvements.

The `skills-auditor` provides structural analysis, while the `improvement-suggester` ranks fixes by impact. Compliance is verified through the `compliance-checker`. Runtime efficiency is monitored by `tool-performance-analyzer` and `token-usage-tracker`.

## Quick Start

### Basic Audit
Run a full audit of all skills or target a specific file to identify structural issues.
```bash
# Audit all skills
make audit-all

# Audit specific skill
make audit-skill TARGET=path/to/skill/SKILL.md
```

### Analysis and Optimization
Use `skill_analyzer.py` for complexity checks and `token_estimator.py` to verify the context budget.
```bash
make analyze-skill TARGET=path/to/skill/SKILL.md
make estimate-tokens TARGET=path/to/skill/SKILL.md
```

### Improvements
Generate a prioritized plan and verify standards compliance using `improvement_suggester.py` and `compliance_checker.py`.
```bash
make improve-skill TARGET=path/to/skill/SKILL.md
make check-compliance TARGET=path/to/skill/SKILL.md
```

## Evaluation Workflow

Start with `make audit-all` to inventory skills and identify high-priority targets. For each skill requiring attention, run analysis with `analyze-skill` to map complexity. Generate an improvement plan, apply fixes, and run `check-compliance` to verify the skill meets project standards. Finalize by checking the token budget for efficiency.

## Evaluation and Optimization

Quality assessments use the `skills-auditor` and `improvement-suggester` to generate detailed reports. Performance ana
