What problem does it solve? Closing a work package often leaves undocumented lessons, missing changelogs, and stale state files, causing teams to repeat mistakes and lose track of what was delivered. This Skill standardizes Phase 11 TRACK/EVALUATE of the THYROX workflow so every work package ends with consistent, auditable closure artifacts. ## Core Features & Use Cases - Lessons Learned Capture: Generates a structured lessons-learned document with root causes, generalizable rules, and an epistemic-debt review of unverified claims from earlier phases. - Changelog & Risk Closure: Produces a Keep-a-Changelog-style WP changelog from git commits, updates the risk register, and archives resolved technical debt entries. - Readiness Validation: Ships a bash script that verifies required artifacts exist before allowing transition to Phase 12 STANDARDIZE. - Use Case: After finishing implementation of a feature branch, run this Skill to produce the lessons-learned file, WP changelog, updated risk register, and closed state files before merging. ## Quick Start Ask the assistant to run the workflow-track phase to evaluate results, document lessons learned, and close the active work package.
