The body is mostly efficient and the classical principle is legitimately domain-specific (not common knowledge), but the Overview and Core Principle sections overlap, and the Validation section re-states the four indicators and the 安/危 classification already covered above. It is at 2 rather than 3 because of this redundancy, and above 1 because it is not padded with generic concept explanations Claude already knows.

It provides a concrete rubric (安 vs 危 with named indicators and a 3-step application procedure), but guidance like 'implement relief measures immediately' is abstract without specifying which measures. It matches the score-2 anchor of some concrete guidance that is incomplete; it is below 3 because key relief actions are not specified, and above 1 because the classification scheme and indicators are concrete.

The Application section gives a clear 3-step sequence and the Validation section provides explicit checkpoints (verify all four indicators assessed, confirm 安/危 classification, check relief measures were recommended). This matches the anchor for a clear sequence with explicit validation steps and a checklist; it is above 2 because validation is explicit rather than implied.

The skill is a single self-contained document under 50 lines with no external references and well-organized sections (Overview, Core Principle, Analysis Framework, Application, Historical Example, Validation). Per the rubric guideline, a sub-50-line skill with no need for external references scores 3 on progressive disclosure with just well-organized sections; it is above 2 because organization is clean with no nested references.

Names multiple concrete actions in a specific domain — 'analyzing rebellion risk', 'diagnosing why uprisings succeed or fail', and 'assess popular contentment vs. endangerment using economic, legal, and safety indicators'. This matches the anchor listing several specific concrete actions; it is above score 2 because it enumerates multiple distinct actions rather than naming only a domain.

It explicitly answers both 'what' (applies the principle to assess contentment vs. endangerment via economic, legal, and safety indicators) and 'when' via an explicit 'Use when analyzing rebellion risk or diagnosing why uprisings succeed or fail' trigger. This matches the score-3 anchor with explicit triggers for both facets; it is above 2 because the 'when' is stated explicitly, not merely implied.

It includes natural terms a user might say ('rebellion risk', 'uprisings succeed or fail', 'rebellion'), but coverage is narrow for a niche domain and lacks common variations or synonyms. It sits at score 2 rather than 3 because the keyword set is not broad, and above 1 because the terms present are genuinely natural rather than jargon.

The niche is highly specific — popular-support / rebellion analysis grounded in a classical Chinese principle (安民可与行义而危民易与为非) and Chen She's rebellion — making conflict with other skills very unlikely. This matches the clear-niche anchor; it is above 2 because the triggers are distinctive rather than generic.
