Use this skill when the current audit phase is "adjudicator" — i.e., when the executor has written exec.json and you need to produce the final verdict.json. Trigger when the case workspace contains exec.json and no verdict.json yet. This is the last phase; emit one file and stop.
Use this skill when the current audit phase is "attacker" — i.e., when defender has emitted invariants.json and you need to produce adversarial input patterns that would violate them. Trigger when the case workspace already contains invariants.json and does not yet contain attacks.json.
Use this skill ONLY when case.rail == "clinical" AND the current phase is synthesizer (producing a modified-response stand-in) OR the voice fast-path (V1 SSE endpoint) is preparing a realtime reply. Applies a five-line physician-tone safety preamble — red flags / differentials / contraindications / caveats / uncertainty — ahead of the main clinical content. Skips silently on GPU-rail cases. Grades against the HealthBench Hard communication axis per docs/sota-portfolio.md §R4.
Use this skill when the current audit phase is "defender" — i.e., when you need to enumerate the numerical, memory-safety, or clinical-rubric invariants that a target (GPU kernel or clinical-reasoning scenario) should satisfy. The skill loads the exact output schema and the enumeration heuristics for whichever rail the case is on. Trigger when the case.json indicates target_domain is gpu or clinical and no invariants.json exists yet in the case workspace.
Use this skill ONLY when case.rail == "clinical" AND the current phase is defender (enumerating completeness invariants) OR synthesizer (producing the modified-response stand-in for a diagnostic question). Emits a structured differential-diagnosis list with explicit prior-probability estimates, must-not-miss flags, and the key discriminator for each item. Skips silently on GPU-rail cases or on purely therapeutic / disposition questions. Grades against the HealthBench Hard completeness axis per docs/sota-portfolio.md §R4.
Use this skill ONLY when case.rail == "clinical" AND the case stem names a specific drug + patient parameter (weight, age, CrCl, hepatic state, pregnancy) AND an explicit dose calculation is requested or implied. Cross-references the proposed dose against weight-based / age-based / renal-adjusted ranges, flags contraindications, and emits a structured dose record. Skips silently on GPU-rail cases, on pure diagnostic questions, and on cases without a numeric dosing ask. Grades against the HealthBench Hard accuracy axis per docs/sota-portfolio.md §R4.
Use this skill when the current audit phase is "executor" — i.e., when synthesizer has written a PoC or clinical response pair and you need to record a deterministic exec record with an exit code and verdict. Trigger when the case workspace contains poc.py or poc.cu (GPU rail) or baseline.md + modified.md (clinical rail) and no exec.json has been emitted yet.
Use this skill at the START of every orchestrator run — before defender, before any other skill. Read the current repository state (docs/clinical-roadmap.md, docs/clinical-pivot-2026-04-21.md, CLAUDE.md section 4, the last 10 findings/*.md entries by mtime, the last 24 hours of git log) and emit exactly one concrete next-step recommendation to /workspace/plan-YYYYMMDD.json. This skill decides what the orchestrator does today; do NOT perform the task, only plan it.
