What problem does it solve? Launching a build on an incomplete manifest wastes worker effort and fails late. This Skill runs the worker-composer's Phase 1 survival test early, catching missing acceptance criteria, unpinned boundary types, or non-discriminating gates before the build starts. ## Core Features & Use Cases - Manifest survival test: Checks every block in building-blocks.yaml for complete specs and concrete tests_nl/ACs, and every boundary for pinned types, contract_test, and projection. - Cross-deploy contract verification: Confirms declared contracts exist (openapi operationIds resolve, event-schema files present) and that the profile gate is executable and discriminating via red-green proof. - Three-way verdict: Reports PASS (launch the worker-composer), BLOCKED (precise misalignments and which step to rework), or EXPLICIT PENDING (parked bounces, open spikes, unsatisfied cleanup nodes). - Use Case: Before running the build on a feature, ask for a readiness check to discover that a high-value block lacks tests_nl, fix it in the model step, and only then launch the worker-composer. ## Quick Start Ask the agent to run the readiness gate on your feature's building-blocks.yaml manifest before launching the worker-composer build.
