Mostly dense and useful (parameter tables, tool signatures, fallback chains), but sections like 'Driver vs Passenger Reasoning' and 'Resistance Reasoning' re-explain oncology biology (EGFR T790M, MET amplification bypass) that Claude already knows, so it could be tightened.

Provides concrete verified parameter tables and one inline executable call signature (ESM_explain_variant_mechanism), but the promised 'detailed code snippets and API call patterns' are deferred to ANALYSIS_DETAILS.md, which does not exist — so copy-paste-ready code is largely absent.

Clear phased sequence (Phase 0-8) with an explicit CRITICAL Phase 0 parameter-verification gate and a Fallback Strategy providing error-recovery feedback loops (empty result -> alternate tool), plus a referenced completeness checklist.

Sections are well-organized, but the sole one-level-deep reference ('see ANALYSIS_DETAILS.md') points to a file that is not present in the bundle, and dense reference material (tool tables, reasoning strategies) is kept inline rather than split out.

Lists multiple concrete actions: 'clinical evidence tier (CIViC, OncoKB), therapeutic options (FDA-approved + investigational), resistance mechanisms, prognosis, and matching clinical trials' — each is a specific, distinct capability rather than vague language.

Explicitly answers both what ('Transforms a gene + variant + cancer-type input into an actionable report...') and when ('Use for tumor-board variant calls...'), with a clear explicit 'Use for' trigger clause.

Natural clinical triggers are present: 'Use for tumor-board variant calls, somatic-mutation actionability assessment, and treatment selection' — terms a precision-oncology user would plausibly say when needing this skill.

Clear niche (somatic cancer mutation interpretation for precision oncology) with cancer-type-specific, tumor-board-oriented triggers that are unlikely to fire for unrelated skills.
