# Performance Assessment Skill

## Purpose

Provides concrete, reproducible performance assessment for PopKit plugins using:
- Measurable efficiency metrics
- Automated context analysis
- Token consumption estimation
- Lazy loading validation

## How to Use

### Step 1: Run Automated Metrics Collection

```bash
python skills/pop-assessment-performance/scripts/measure_context.py packages/plugin/
python skills/pop-assessment-performance/scripts/analyze_loading.py packages/plugin/
python skills/pop-assessment-performance/scripts/calculate_efficiency.py packages/plugin/
```

### Step 2: Apply Performance Checklists

Read and apply checklists in order:
1. `checklists/context-efficiency.json` - Context window usage
2. `checklists/startup-performance.json` - Plugin initialization
3. `checklists/file-access-patterns.json` - Read/write efficiency

### Step 3: Generate Report

Combine automated metrics with checklist results for final performance report.

## Standards Reference

| Standard | File | Key Checks |
|----------|------|------------|
| Context Efficiency | `standards/context-efficiency.md` | CE-001 through CE-008 |
| Startup Performance | `standards/startup-performance.md` | SP-001 through SP-006 |
| File Access | `standards/file-access.md` | FA-001 through FA-008 |
| Token Consumption | `standards/token-consumption.md` | TC-001 through TC-006 |

## Performance Targets

| Metric | Target | Warning | Critical |
|--------|--------|---------|----------|
| Skill Prompt Size | <2000 tokens | 2000-4000 | >4000 |
| Agent Prompt Size | <5000 tokens | 5000-8000 | >8000 |
| Tier-1 Agent Count | <=15 | 16-20 | >20 |
| File Reads/Operation | <5 | 5-10 | >10 |
| Startup Files | <10 | 10-20 | >20 |

## Output

Returns JSON with:
- `efficiency_score`: 0-100 (higher = better)
- `metrics`: Collected performance measurements
- `bottlenecks`: Identified performance issues
- `optimizations`: Recommended improvements
