Conciseness

Mostly efficient operational content (tool parameters, fallbacks, thresholds), but Phase 6 inlines a ~65-line classify_acmg function, the Bayesian point table, and gene-specific BS1 thresholds while simultaneously pointing to ACMG_CLASSIFICATION.md "for the complete algorithm", and editorial asides pad the text ("This is one of the most challenging scenarios in variant interpretation", "This system handles conflicting evidence naturally..."). Not 4: the duplication and padding exceed minor instances of over-explanation.

Actionability

Fully executable and copy-paste ready: the classify_acmg function runs as-is with a worked PALB2 c.2816T>G example, tools are documented with concrete parameters and return shapes (e.g. VariantValidator's genome_build/variant_description, ClinGenAllele coordinate gotcha), plus a gnomAD two-step recipe, tool-failure fallback chains, output report template, file naming convention, and quantified minimums. Matches anchor 5; not 4 because common cases are covered without gaps.

Workflow Clarity

Clear six-phase sequence with an overview map, conditional phases (2.5 non-coding only, 4 VUS/novel), the "LOOK UP, DON'T GUESS" gate, a Phase 2.9 short-circuit checkpoint, explicit tool-failure feedback loops (e.g. "ClinVar_search_variants returns 0 results: Use MyVariant_query_variants"), and a pre-delivery CHECKLIST.md plus quantified minimums as verification. Anchor 5 (explicit validation steps, error-recovery loops, checklist); not 4 since checkpoints are explicit rather than implicit.

Progressive Disclosure

References are clearly signaled and one level deep (inline "See ACMG_CLASSIFICATION.md for thresholds" pointers plus a final References section), but ~100 lines of Phase 6 detail that belong in ACMG_CLASSIFICATION.md are inlined in SKILL.md, and none of the five referenced files (ACMG_CLASSIFICATION.md, CODE_PATTERNS.md, CHECKLIST.md, EXAMPLES.md, TOOLS_REFERENCE.md) exist in the provided bundle — no references/ directory is present, so every "See X" link is dangling. Anchor 3 (content that should be separate is inline); not 4 because of the inline bulk and unverifiable references, not 2 because structure and signaling are genuinely present.

Specificity

Lists multiple specific concrete actions with comprehensive coverage: "VUS classification", "pathogenicity assessment with cited criteria", "structure-based variant impact (AlphaFold/PDB)", "non-coding/regulatory variant effect prediction with sequence deep-learning models (AlphaGenome, Enformer, Borzoi, ChromBPNet, Evo 2)", and "producing clinical-grade variant reports" span the whole pipeline from raw calls to reports. Not 4: there are no minor gaps in capability coverage.

Completeness

Explicitly answers both: what ("Clinical variant interpretation from raw variant calls to ACMG-classified recommendations with structural impact analysis") and when ("Use for..." and "Use this whenever a user asks about a variant's significance, an intronic/promoter/enhancer/UTR non-coding variant's functional impact, or needs ACMG classification"). Matches the anchor-5 example structure exactly; not 4 because the when-clause is fully explicit with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage including synonyms: "a variant's significance", "intronic/promoter/enhancer/UTR non-coding variant's functional impact", "ACMG classification", plus explicit synonym handling ("even if they don't say 'ACMG'") and domain phrasings users actually say ("VUS", "molecular tumor boards", "return of results"). Not 4: no commonly used natural phrasing is missing.

Distinctiveness Conflict Risk

Clear niche (clinical/ACMG variant interpretation) with distinct triggers, but phrases like "a variant's... functional impact" and "structural impact analysis" could plausibly trigger a general sequence-analysis or structural-bioinformatics sibling skill (the body itself references a tooluniverse-sequence-analysis skill). Mostly distinct with minor overlap risk against closely related skills — anchor 4; not 5 because of that overlap, not 3 because the clinical/ACMG framing is strongly distinctive.
