SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill audits a completed phase for missing Nyquist validation coverage and reconstructs the evidence needed to close gaps after the fact.

Core Features & Use Cases

  • Validation Gap Audit: Reviews an existing phase for incomplete, absent, or inconsistent validation records.
  • Artifact Reconstruction: Rebuilds validation context from SUMMARY.md and related phase artifacts when VALIDATION.md is missing.
  • Test Generation: Produces updated VALIDATION.md content and generated test files to verify the phase outcome.
  • Use Case: A team finishes a phase, discovers validation was never formalized, and needs a deterministic recovery path that preserves workflow gates.

Quick Start

Ask the assistant to audit the specified completed phase, reconstruct any missing validation evidence, and generate an updated VALIDATION.md with the required test files.

FAQPage Schema
How do I fix missing phase validation coverage after a workflow has already completed?

Phase validation reconstruction rebuilds missing validation context from SUMMARY.md files and partial execution evidence. It audits completed phases to identify coverage gaps and generates the updated VALIDATION.md and test files needed to preserve workflow gates.

Can I reconstruct a VALIDATION.md file if it was never created during the phase?

Yes, you can reconstruct a missing VALIDATION.md by recovering validation context from SUMMARY.md artifacts and partial execution evidence. This deterministic recovery path generates the required validation records and test files while preserving the original phase process.

How do I audit an existing phase for incomplete or inconsistent validation records?

You audit an existing phase by reviewing its validation files and summary artifacts for incomplete, absent, or inconsistent validation records. The audit identifies missing Nyquist validation coverage and triggers a workflow-gated reconstruction to generate the required test files.

What is Nyquist validation gap coverage and when do I need to reconstruct it?

Nyquist validation gap coverage measures the completeness of validation records across a finished phase. You need to reconstruct it when a phase completes without formalized validation, requiring artifact recovery and test generation to close the missing coverage gaps.

Does phase validation reconstruction require workflow gates to regenerate test files?

Yes, phase validation reconstruction requires workflow-gated recovery to regenerate test files. This ensures the reconstructed validation evidence and updated VALIDATION.md content preserve the integrity of the original phase process.
