What problem does it solve? SparkEngine's code looks feature-complete and its hygiene signals are green, yet its release contract reports 0 of 18 gates passing. This Skill resolves the gap between implemented code and provable readiness by enforcing a single machine-validated source of truth (readiness.json plus work-item JSON files) for every public status claim. ## Core Features & Use Cases - Readiness status queries: Answer "is subsystem X release-ready?" by reading the four independent capability dimensions (implementation, verification, support, release) from docs/site/readiness.json instead of trusting prose status pages or TODO counts. - Work item lifecycle: Pick up, progress, and close tracked items (RDY, CI, MOD, etc.) with strict schema validation, dependency ordering, and exact-SHA CI evidence requirements. - Wiring audits: Run caller/registration/tick/teardown checks (check-wiring.sh, check-test-registration.sh, check-editor-panels.sh) before claiming any system is done. - Use Case: A maintainer asks "what's blocking the release?" — the Skill reads the generated handoff verdict block, lists the 49 unfinished blocking items, and identifies RDY-000 as the only unblocked starting point. ## Quick Start Ask the assistant to check the current release readiness status of SparkEngine and list which work items are blocking the release.
