The body is lean (~35 lines) and well-organized with every section earning its place; it assumes competence and does not pad with background Claude already knows. Meets the score-3 'lean and efficient' anchor.

Some practices are concrete ("spit out food and rise to greet them", "stop and grasp wet hair"), but the Maintain Humility and Warning Against Pride sections are abstract directives without concrete execution guidance. As an instruction-only skill code is not required, but the abstract sections keep it at 2 rather than 3.

For this simple single-purpose skill the sequence (Practices → Expected Outcomes → Validation) is clear, and the Validation section provides explicit verification checkpoints. Meets the simple-skills allowance for a 3 with clear organization plus validation steps.

No bundle files exist and none are needed for a <50-line skill; the body is split into clear, well-labeled sections (Overview, Core Principle, Practices, Expected Outcomes, Key Insight, Validation). Meets the simple-skills allowance for a 3 based on well-organized sections.

Names the domain and some actions ("interrupting meals and baths to receive scholars", "prevent losing capable people"), but these are conceptual rather than a comprehensive list of concrete actions. It is above score 1 because concrete actions are named, but below 3 because no enumerated set of specific capabilities is given.

Explicitly answers both what ("Follows Zhou Gong's practice of interrupting meals and baths to receive scholars... to prevent losing capable people") and when ("Use when attracting talented advisors or demonstrating respect for worthy individuals") with an explicit trigger clause. Meets the score-3 anchor for an explicit 'Use when...' trigger plus a clear statement of what the skill does.

Includes relevant natural terms like "talented advisors", "worthy individuals", and "capable people", but the historical framing and Chinese idiom (一沐三握发, 一饭三吐哺) are jargon that few users would naturally say, and common variations are missing. Not 1 because usable English keywords exist; not 3 because coverage of natural user phrasing is thin.

The niche historical/behavioral subject (Zhou Gong's worthy-people practice) and distinctive trigger terms make it clearly distinguishable and very unlikely to fire for the wrong skill. Clearly above score 2, which requires overlap risk.
