Verification & Quality Assurance

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

# 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:

# 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:

# 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:

# 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)
• ` verification.json

Example JSON structure:

{ "overallScore": 0.947, "passed": true, "threshold": 0.95, "checks": [ { "name": "code-correctness", "score": 0.98, "passed": true }, { "name": "security", "score": 0.91, "passed": false, "issues": [...] } ] }

### Automatic Rollback

#### Rollback Failed Changes

Automatically revert changes that fail verification checks.

**Basic Rollback:**
```bash
# Rollback to last known good state
npx claude-flow@alpha verify rollback --last-good

# Rollback to specific commit
npx claude-flow@alpha verify rollback --to-commit abc123

# Interactive rollback with preview
npx claude-flow@alpha verify rollback --interactive

Smart Rollback:

# Rollback only failed files (preserve good changes)
npx claude-flow@alpha verify rollback --selective

# Rollback with automatic backup
npx claude-flow@alpha verify rollback --backup-first

# Dry-run mode (preview without executing)
npx claude-flow@alpha verify rollback --dry-run

Rollback Performance:

• Git-based rollback: verification.json

• name: Check Truth Score

run: | score=$(jq '.overallScore' verification.json) if (( $(echo "$score verification.json

• |

score=$(jq '.overallScore' verification.json) if [ $(echo "$score /tmp/verify.json

score=$(jq '.overallScore' /tmp/verify.json) if (( $(echo "$score --format json

**Rollback Failures:**
```bash
# Check git status
git status

# View rollback history
npx claude-flow@alpha verify rollback --history

# Manual rollback
git reset --hard HEAD~1

Verification Timeouts:

# Increase timeout
npx claude-flow@alpha verify check --timeout 60s

# Verify in batches
npx claude-flow@alpha verify batch --batch-size 10

Exit Codes

Verification commands return standard exit codes:

• 0: Verification passed (score ≥ threshold)
• 1: Verification failed (score < threshold)
• 2: Error during verification (invalid input, system error)

Related Commands

• npx claude-flow@alpha pair - Collaborative development with verification
• npx claude-flow@alpha train - Training with verification feedback
• npx claude-flow@alpha swarm - Multi-agent coordination with quality checks
• npx claude-flow@alpha report - Generate comprehensive project reports

Best Practices

1. Set Appropriate Thresholds: Use 0.99 for critical code, 0.95 for standard, 0.90 for experimental
2. Enable Auto-rollback: Prevent bad code from persisting
3. Monitor Trends: Track improvement over time, not just current scores
4. Integrate with CI/CD: Make verification part of your pipeline
5. Use Watch Mode: Get immediate feedback during development
6. Export Metrics: Track quality metrics in your monitoring system
7. Review Rollbacks: Understand why changes were rejected
8. Train Agents: Use verification feedback to improve agent performance
