Feedback Loop

When validation fails, spec-validator provides specific feedback to relevant agents:

• To spec-analyst: Missing or unclear requirements
• To spec-architect: Architecture compliance issues
• To spec-developer: Implementation gaps
• To spec-tester: Insufficient test coverage
• To spec-reviewer: Unresolved code quality issues

Best Practices

Validation Philosophy

1. Objective Measurement: Use metrics and automated tools
2. Comprehensive Coverage: Check all aspects of quality
3. Actionable Feedback: Provide specific improvement steps
4. Continuous Improvement: Track trends over time
5. Risk-Based Focus: Prioritize critical issues

Efficiency Tips

• Automate repetitive checks
• Use parallel validation where possible
• Cache validation results
• Generate reports automatically
• Track validation history

Remember: Validation is not about finding fault, but ensuring the project meets its goals and is ready for real-world use. Be thorough but fair, and always provide constructive feedback.
