## Usage

### Requirements
- Python 3.7+ (no external dependencies - uses only stdlib)

### Analyze a Skill

```bash
# Analyze a local skill
python3 scripts/analyzer.py --path /path/to/skill

# Analyze with detailed output
python3 analyzer.py --path /path/to/skill --verbose

# Output to JSON
python3 analyzer.py --path /path/to/skill --output report.json

# Compare two skills
python3 analyzer.py --compare skill1 skill2
```

### Dimensions Scoring

Each dimension is scored 0-10:
- 8-10: Excellent
- 6-7: Good
- 4-5: Average
- 2-3: Below Average
- 0-1: Poor/Needs Improvement

## Example Output
