What problem does it solve? Project teams often finish work without systematically capturing what went well, what failed, and what to change, so the same mistakes repeat across projects. This Skill produces a structured, sign-off-ready lessons learned document during Phase 13 (Closure) of the SDLC. ## Core Features & Use Cases - Structured Retrospective Documentation: Generates a complete lessons learned document covering successes, challenges, root cause analysis, metrics, and recommendations. - Governed Sign-Off Workflow: Enforces validation rules, prerequisite signature checks, and Project Manager approval before the document is accepted. - Traceable Sources File: Writes a sources file recording predecessor documents, question history, and information gaps for auditability. - Use Case: After a project closes, a project manager invokes the skill to compile team feedback, defect logs, and closure report data into a signed lessons learned document stored at documentation/13-closure/lessons-learned.md. ## Quick Start Ask the agent to generate the lessons learned document for your completed project using the signed closure report and team retrospective input.
