# Verification & Quality Assurance Skill

## What This Skill Does

This skill provides a comprehensive verification and quality assurance system that ensures code quality and correctness through:

- **Truth Scoring**: Real-time reliability metrics (0.0-1.0 scale) for code, agents, and tasks
- **Verification Checks**: Automated code correctness, security, and best practices validation
- **Automatic Rollback**: Instant reversion of changes that fail verification (default threshold: 0.95)
- **Quality Metrics**: Statistical analysis with trends, confidence intervals, and improvement tracking
- **CI/CD Integration**: Export capabilities for continuous integration pipelines
- **Real-time Monitoring**: Live dashboards and watch modes for ongoing verification

## Prerequisites

- Claude Flow installed (`npx claude-flow@alpha`)
- Git repository (for rollback features)
- Node.js 18+ (for dashboard features)

## Quick Start

```bash
# View current truth scores
npx claude-flow@alpha truth

# Run verification check
npx claude-flow@alpha verify check

# Verify specific file with custom threshold
npx claude-flow@alpha verify check --file src/app.js --threshold 0.98

# Rollback last failed verification
npx claude-flow@alpha verify rollback --last-good
```

## Complete Guide

### Truth Scoring System

#### View Truth Metrics

Display comprehensive quality and reliability metrics for your codebase and agent tasks.

**Basic Usage:**
```bash
# View current truth scores (default: table format)
npx claude-flow@alpha truth

# View scores for specific time period
npx claude-flow@alpha truth --period 7d

# View scores for specific agent
npx claude-flow@alpha truth --agent coder --period 24h

# Find files/tasks below threshold
npx claude-flow@alpha truth --threshold 0.8
```

**Output Formats:**
```bash
# Table format (default)
npx claude-flow@alpha truth --format table

# JSON for programmatic access
npx claude-flow@alpha truth --format json

# CSV for spreadsheet analysis
npx claude-flow@alpha truth --format csv

# HTML report with visualizations
npx claude-flow@alpha truth --format html --export report.html
```

**Real-time Monitoring:**
```bash
# Watch mode with live updates
npx claude-flow@alpha truth --watch

# Export metrics automatically
npx claude-flow@alpha truth --export .claude-flow/metrics/truth-$(date +%Y%m%d).json
```

#### Truth Score Dashboard

Example dashboard output:

📊 Truth Metrics Dashboard
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Overall Truth Score: 0.947 ✅
Trend: ↗️ +2.3% (7d)

Top Performers:
  verification-agent   0.982 ⭐
  code-analyzer       0.971 ⭐
  test-generator      0.958 ✅

Needs Attention:
  refactor-agent      0.821 ⚠️
  docs-generator      0.794 ⚠️

Recent Tasks:
  task-456  0.991 ✅  "Implement auth"
  task-455  0.967 ✅  "Add tests"
  task-454  0.743 ❌  "Refactor API"
```

#### Metrics Explained

**Truth Scores (0.0-1.0):**
- `1.0-0.95`: Excellent ⭐ (production-ready)
- `0.94-0.85`: Good ✅ (acceptable quality)
- `0.84-0.75`: Warning ⚠️ (needs attention)
- `<0.75`: Critical ❌ (requires immediate action)

**Trend Indicators:**
- ↗️ Improving (positive trend)
- → Stable (consistent performance)
- ↘️ Declining (quality regression detected)

**Statistics:**
- **Mean Score**: Average truth score across all measurements
- **Median Score**: Middle value (less affected by outliers)
- **Standard Deviation**: Consistency of scores (lower = more consistent)
- **Confidence Interval**: Statistical reliability of measurements

### Verification Checks

#### Run Verification

Execute comprehensive verification checks on code, tasks, or agent outputs.

**File Verification:**
```bash
# Verify single file
npx claude-flow@alpha verify check --file src/app.js

# Verify directory recursively
npx claude-flow@alpha verify check --directory src/

# Verify with auto-fix enabled
npx claude-flow@alpha verify check --file src/utils.js --auto-fix

# Verify current working directory
npx claude-flow@alpha verify check
```

**Task Verification:**
```bash
# Verify specific task output
npx claude-flow@alpha verify check --task task-123

# Verify with custom threshold
npx claude-flow@alpha verify check --task task-456 --threshold 0.99

# Verbose output for debugging
npx claude-flow@alpha verify check --task task-789 --verbose
```

**Batch Verification:**
```bash
# Verify multiple files in parallel
npx claude-flow@alpha verify batch --files "*.js" --parallel

# Verify with pattern matching
npx claude-flow@alpha verify batch --pattern "src/**/*.ts"

# Integration test suite
npx claude-flow@alpha verify integration --test-suite full
```

#### Verification Criteria

The verification system evaluates:

1. **Code Correctness**
   - Syntax validation
   - Type checking (TypeScript)
   - Logic flow analysis
   - Error handling completeness

2. **Best Practices**
   - Code style adherence
   - SOLID principles
   - Design patterns usage
   - Modularity and reusability

3. **Security**
   - Vulnerability scanning
   - Secret detection
   - Input validation
   - Authentication/authorization checks

4. **Performance**
   - Algorithmic complexity
   - Memory usage patterns
   - Database query optimization
   - Bundle size impact

5. **Documentation**
   - JSDoc/TypeDoc completeness
   - README accuracy
   - API documentation
   - Code comments quality

#### JSON Output for CI/CD

```bash
# Get structured JSON output
npx claude-flow@alpha verify check --json > verification.json

# Example JSON structure:
{
  "overallScore": 0.947,
  "passed": true,
  "threshold": 0.95,
  "checks": [
    {
      "name": "code-correctness",
