What problem does it solve? Finalizing a completed change in an OpenSpec workflow involves checking artifact completion, task status, and delta spec synchronization before moving the change into an archive directory. Doing this manually is error-prone and can leave main specs out of sync with the change. ## Core Features & Use Cases - Guided change selection: Infers the change from context, auto-selects when only one active change exists, or prompts with a list of active changes when ambiguous. - Completion verification: Checks artifact status via openspec status --json and counts incomplete tasks in tasks.md, warning but not blocking on gaps. - Delta spec sync assessment: Compares delta specs against main specs, optionally runs an inline sync workflow, and verifies the result before archiving. - Use Case: After finishing implementation of a user-auth change, ask the assistant to archive it; the skill validates artifacts and tasks, syncs specs if needed, and moves the change to archive/YYYY-MM-DD-user-auth. ## Quick Start Ask the assistant to archive the completed change named add-user-auth using the openspec archive workflow.
