What problem does it solve? Closing a work package without structured evaluation loses lessons learned, leaves changelogs unwritten, and lets unverified claims accumulate as epistemic debt. This Skill enforces Phase 11 TRACK/EVALUATE of the THYROX workflow so every work package ends with documented results, risks, and knowledge. ## Core Features & Use Cases - Lessons Learned Capture: Generates a structured lessons-learned document with root causes, generalizable rules, and reusable patterns using a dedicated template. - Changelog & Risk Closure: Produces a Keep-a-Changelog-style WP changelog from commits and updates the risk register, closing risks that did not materialize. - Epistemic Debt Audit: Reviews all prior stages for inherited claims never re-verified, listing them with status and recommended actions. - Readiness Validation: Ships a bash script that checks required artifacts (lessons-learned, changelog, risk register) exist before allowing phase transition. - Use Case: After finishing implementation of a feature work package, run Phase 11 to produce the lessons-learned file, WP changelog, resolved technical-debt register, and updated state files before the human gate approves transition to Phase 12 STANDARDIZE. ## Quick Start Ask the assistant to run the workflow-track phase to evaluate the active work package, generate its lessons-learned and changelog artifacts, and close it out.
