SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams review a finished implementation against its specification, plan, and task list so they can quantify drift, spot missed requirements, and capture lessons for future work.

Core Features & Use Cases

  • Spec Adherence Analysis: Compare the implementation to spec.md, plan.md, and tasks.md to identify what was implemented, modified, partially done, or omitted.
  • Drift and Risk Review: Detect architecture changes, task mismatches, constitution issues, and other deviations that could affect quality or delivery.
  • Actionable Retrospectives: Produce a concise retrospective report with findings, severity levels, proposed spec changes, and follow-up recommendations.

Quick Start

Ask this Skill to analyze the completed feature and generate a retrospective report from the project’s spec, plan, and task files.

Frequently Asked Questions about speckit-retrospective-analyze

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I measure spec drift after a feature implementation?▼

You measure spec drift by comparing completed implementations against specification documents, plans, and task lists to identify deviations, missed requirements, and task mismatches affecting delivery quality.

What is a post-implementation retrospective for software projects?▼

A post-implementation retrospective analyzes completed implementations against specifications to quantify drift, review architecture changes and blockers, and capture actionable lessons for future work.

How do I check requirement coverage and constitution compliance?▼

You check requirement coverage and constitution compliance by auditing completed implementations against specification documents to classify severity levels and identify missed or modified requirements.

Can I generate an actionable retrospective report from spec files?▼

Yes, you can generate a concise retrospective report from spec, plan, and task files that includes findings, severity levels, proposed spec changes, and follow-up recommendations for future work.

Does this approach require spec, plan, and task list files to work?▼

Yes, this retrospective analysis requires spec-kit projects containing spec.md, plan.md, and tasks.md files to compare implementations and measure adherence, drift, and task completion accurately.

What is the best way to identify missed requirements in a completed implementation?▼

The best way to identify missed requirements is comparing the implementation to spec.md and tasks.md to detect what was partially done, omitted, or modified, then classifying severity levels for reporting.
