What problem does it solve? Closing a milestone in an aiwf-tracked project involves many error-prone steps: verifying every acceptance criterion is met, running independent code and design reviews, finalizing the milestone spec's wrap-side sections, promoting status to done, and producing correctly trailered git commits. This Skill orchestrates that entire closure ritual so nothing is skipped and no inconsistent state reaches the remote. ## Core Features & Use Cases - Completion verification: Walks every AC in the milestone spec, runs aiwf check, the full test suite, build, and lint gate, and stops if anything is red. - Independent two-lens review: Dispatches fresh-context reviewers for code quality (wf-review-code) and design quality (wf-rethink) over the milestone's full change-set, with corrective commits for blocking findings. - Spec finalization and gated commit: Fills in Release note, Validation, Deferrals, and Reviewer notes sections, regenerates the roadmap, and prepares a trailered wrap commit that requires explicit human approval before commit and push. - Use Case: After finishing implementation of milestone M-0007, tell the assistant to wrap it; the Skill verifies all gates, runs the review loop, closes any gaps the milestone fixed, promotes the milestone to done, and merges the milestone branch into the epic branch with proper aiwf trailers. ## Quick Start Ask the assistant to wrap milestone M-NNNN once its implementation is complete and the readiness check from aiwfx-start-milestone has passed.
