Conciseness

The body is operational rather than explanatory, but the never-fabricate rule is restated roughly four times ('Do not invent model availability', Hard Rules 1–2, 'What This Skill Should Not Do', Section K) and the reference modules are listed twice (the integration section plus inline re-mentions like 'Use `references/study-patterns.md`' in Step 3). Anchor 3 fits: mostly efficient but could be tightened; not anchor 4 because the repetition is more than minor over-explanation.

Actionability

Guidance is concrete and executable for an instruction-only skill: an exact 11-section output structure with per-section table columns ('model family / what it is testing / strengths…'), a 7-step decision procedure, and four named workload configurations. Not anchor 5 because there is no worked example of a filled-in plan — the closest analog to 'specific examples cover the common cases' — leaving minor gaps despite the precise template.

Workflow Clarity

The Decision Logic is a clearly ordered 7-step sequence (lock claim → tier → pattern → model → perturbation → sequencing → success criteria) with explicit validation checkpoints: mandatory resource-clarification follow-up questions, go/no-go gates in Section H, escalation criteria, and a required self-critical risk review (Hard Rule 12). This matches the anchor for clear sequence with explicit validation steps and feedback loops.

Progressive Disclosure

The 'Reference Module Integration' section maps each of the nine one-level-deep reference files to a specific output section ('references/workload-configurations.md → Section B'), all referenced paths exist on disk, and SKILL.md stays an operational overview while detail lives in the references. This is a textbook match for the clear-overview, well-signaled-references anchor.

Specificity

The description lists many concrete actions — 'define the exact claim to test', 'specify perturbation strategy, readouts, controls, sequencing of experiments', 'four workload configurations (Lite / Standard / Advanced / Publication+)' — with comprehensive coverage and no vague filler. This matches the anchor for multiple specific concrete actions; the trailing never-fabricate sentence adds behavioral rules rather than padding, so it stays at 5 rather than 4.

Completeness

It explicitly answers both questions: what ('Designs cell-based and animal-based validation plans that translate… findings into experimentally testable validation routes') and when ('Always use this skill whenever a user wants to move from an in silico, statistical, or clinical association finding toward wet-lab validation…'), with concrete trigger conditions. This is a direct match for the top anchor.

Trigger Term Quality

Natural user phrasings are covered with synonyms on both the finding side ('computational, omics, biomarker, genetic, or clinical findings', 'in silico, statistical, or clinical association finding') and the model side ('cell systems, organoid-like systems, xenograft or genetically relevant animal models', 'wet-lab validation'). This matches the comprehensive-synonyms anchor; only marginal terms like 'in vitro' or 'mouse model' are absent, which is not enough to drop to the 'a few natural terms missing' anchor 4.

Distinctiveness Conflict Risk

The niche — designing wet-lab cell/animal validation plans for computational or clinical findings — is distinct and the triggers (organoid, xenograft, 'move from clinical association to mechanistic validation') would not plausibly fire a neighboring skill. Minimal conflict risk matches the clear-niche anchor.
