What problem does it solve? Keeping a Product Requirements Document in sync with actual implementation work is tedious and error-prone; this Skill analyzes completed work and proposes evidence-based checkbox and status updates to the PRD. ## Core Features & Use Cases - Context-First Progress Analysis: Uses conversation context and todo lists first, falling back to git log and diff analysis only when context is unclear. - Evidence-Based Completion: Categorizes unchecked requirements (implementation, documentation, validation, launch, metrics) and only marks items complete with direct evidence such as passing tests, mypy, and ruff checks. - Divergence Detection and Commits: Flags where implementation differs from the plan, updates outdated code examples, and commits progress with a PRD-referenced message. - Use Case: After finishing a feature described in PRD #12, run this Skill to detect which requirements are now satisfied, update the checkboxes, commit the progress checkpoint, and get routed to /prd-next or /prd-done. ## Quick Start Ask the assistant to update the current PRD's progress based on the work just completed in this session.
