What problem does it solve? The stock spec-kit workflow has no terminal step and force-closes features without ever recording a completed status, leaving the Active → Completed lifecycle unfinished. This Skill provides the explicit completion gate by writing status: completed to the feature's .spec-context.json through the sanctioned write-context.py script. ## Core Features & Use Cases - Terminal Status Write: Runs write-context.py --mark-complete to set status: completed while keeping currentStep at implement, preserving the history invariant. - Living Spec Delta Folding: Optionally folds ADDED/MODIFIED/REMOVED/RENAMED requirement blocks into durable capability specs, with explicit skip recording for untouched capabilities. - Graceful Degradation: Skips with a warning when python3 is missing and exits cleanly when a spec is already completed or archived. - Use Case: After finishing the implement step of a spec-kit Companion feature, run this step so the spec lands at the end of the lifecycle and living-spec changes are synced back to capability specs. ## Quick Start Ask the AI to mark the current spec-kit feature complete by running the companion write-context script with the mark-complete flag from the repository root.
