The body is lean (~57 lines) with no padding explaining concepts Claude already knows — each condition is just Chinese term, translation, signs, and prognosis, plus a compact IF/ELSE and a 3-item verification checklist. It is not below 3 because there is no unnecessary explanation; the repeated 'Prognosis: Cannot be treated' lines are a deliberate scannable structure rather than concept-fluff.

As an instruction-only skill it gives concrete, actionable guidance: six named conditions with specific observable signs ('Patient refuses to listen to reason', 'Unwilling to spend money on treatment'), a clear IF/ELSE decision rule, and a verification checklist requiring documentation 'with specific observed signs (not assumptions)'. Per the code_vs_instruction note, the absence of code is not penalized because the guidance is actionable.

The screening workflow is unambiguous — assess the six conditions, then the IF/ELSE ('Decline treatment or set expectations appropriately' vs 'Proceed with standard diagnosis'), followed by a 3-step verification checklist that serves as explicit checkpoints. Per the simple_skills note, a clear single-action screening decision can score 3, and no feedback loop is required since this is not a destructive/batch operation.

No bundle files exist and none are referenced, so there is nothing to verify; the single self-contained file is well-organized into clear sections (Overview, Six Conditions, Decision Framework, Clinical Application, Verification) with no nested references. Per the simple_skills note, a small single-purpose skill with no need for external references earns 3 from well-organized sections alone.

It lists multiple concrete actions — 'screening patients before committing treatment resources' and 'identify six incurable conditions' — and enumerates the six specific conditions, matching the 'lists multiple specific concrete actions' anchor; it is not vague like 'Helps with documents'. Voice is third person ('Applies...'), so no specificity penalty applies.

It explicitly answers both what ('Applies Bian Que's 六不治 framework to identify six incurable conditions...') and when ('Use when screening patients before committing treatment resources') with an explicit 'Use when' trigger, matching the 'clearly answers both what AND when' anchor.

It has some natural keywords a clinician would say ('screening patients', 'incurable conditions', 'treatment resources'), but the parenthetical list (arrogance, greed, yin-yang chaos, trust in shamans over physicians) is domain content rather than natural trigger phrasings, and common variations ('is this patient treatable', 'should I take this case') are missing — closer to 'some relevant keywords but missing common variations' than to full natural-term coverage.

The niche is highly specific — 'Bian Que's 六不治 framework' with six named conditions — giving it distinct triggers unlikely to overlap with other skills, matching the 'clear niche with distinct triggers; unlikely to conflict' anchor rather than the generic 'would conflict with many skills' case.
