Validate Plan

Overview

Comprehensive validation workflow for development implementation plans. This skill systematically analyzes plans against DRY (Don't Repeat Yourself), YAGNI (You Aren't Gonna Need It), and TDD (Test-Driven Development) principles while performing codebase-aware gap analysis to prevent implementation disasters.

Use when:

• Reviewing implementation plans created by /writing-plans
• Validating development plans before execution
• Checking plans for DRY/YAGNI/TDD compliance
• Preventing over-engineering and scope creep
• Ensuring test-first approach in development workflow

Triggers: /validate-plan or "Validate this implementation plan"
