Based on SOC occupation classification
Orchestration skill: chains the full ADLC Build Loop. PRD → Brief → Council → Scaffold → Codegen → LDD → TDD → Council → PR. Use when implementing a new feature end-to-end.
Generate a bounded, schema-valid goal prompt from one validated Build Brief task for zero-context external execution.
Applicability-aware Definition of Done checklist. Core checks apply to every task; overlay checks activate only when the applicability manifest says the surface exists. Binary verification — pass or fail. Triggers at Phase 4 completion and Phase 5 entry.
Score whether each task is specific enough for autonomous, one-shot, production-ready execution.
Reviews code changes for understanding, blast radius, state, secrets, assumptions, and explainability. Produces a blocking comprehension artifact when implications are unclear.
Resolve ambiguous triage outcomes in the middle confidence band.

material means the mutant could hide a real regression or missing assertion.trivial means the survivor is noise: equivalent behavior, logging-only drift, or unreachable semantics that the verifier contract intentionally ignores.weak, regardless of aggregate kill rate.
