planning-validator

What problem does it solve?

It prevents drift and silent planning errors by validating that each planning artifact is complete, consistent, and contract-compliant, with evidence-backed findings before downstream agents act.

Core Features & Use Cases

• Cross-plan validation in 4 modes: phase validation, per-story validation, cross-story validation, and impact analysis to assess blast radius of changes.
• Evidence-first, fail-default validation posture: every check defaults to NEEDS WORK and requires explicit evidence to pass.
• Guidance packaging for re-dispatch: produces structured guidance packages with reasoned corrections and documentation fetch instructions for context7-based retrieval.
• Coverage checks for traceability and correctness: validates traceability, consistency, completeness, conflict detection, semantic spot-checks, and terminology enforcement, including contract compliance.

Quick Start

Use the planning-validator skill to cross-check newly produced plan artifacts after each planning phase, ensuring every acceptance criterion and contract dependency is traceable, consistent, and validated with explicit evidence.
