What problem does it solve? When a master-plan slice is implemented directly via a quick brief without a focused Plan, there is no structured closeout: canonical docs drift, delivery evidence is lost, and temporary workflow artifacts linger. This Skill performs the mandatory closeout for that direct delivery route. ## Core Features & Use Cases - Slice Receipt Management: Writes exactly one row to the master plan's Slice delivery receipts table, recording route, state, and evidence with strict acceptance-state rules. - Canonical Doc Updates: Synchronizes reference documentation when a slice changes user-visible capabilities, APIs, data models, or conventions, then regenerates generated indexes via check_docs.py. - Full Gate Verification: Runs stage_check.py and doc checks, applying bounded regression-repair policy without weakening checks or broadening scope. - Artifact Cleanup: Removes redundant Plans created for already-delivered atomic slices while preserving Plans with real history. - Use Case: After a quick-executor ships slice MP-03 and its focused check passes, run this Skill to record the receipt, update docs, verify all gates, and delete the redundant Plan directory. ## Quick Start Close out master-plan slice MP-03 delivered by the quick route using its brief, executor report, and passing focused check.
