What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves several manual checks—verifying the project board status, confirming artifact and task completion, moving directories, and writing a retrospective. This Skill automates that entire archive procedure with built-in guardrails so nothing is archived prematurely. ## Core Features & Use Cases - Board Status Verification: Runs a verification script against the GitHub Project board and refuses to archive unless the item's Status is Done. - Completion Checks: Parses openspec status --json for incomplete artifacts and scans tasks.md for unchecked items, prompting for confirmation before proceeding. - Dated Archive Move: Moves the change directory to openspec/changes/archive/YYYY-MM-DD-<name> with collision detection. - Chained Retrospective: Writes or appends a retrospective stub at retros/<change-id>.md as a mandatory Gate F deliverable. - Use Case: After merging the implementation PR for a change, ask the assistant to archive it; the Skill verifies the board shows Done, confirms all artifacts and tasks are complete, moves the directory, and creates the retro file. ## Quick Start Archive the completed OpenSpec change named add-user-auth after verifying its project board status is Done.
