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)

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