The body is lean and assumes competence — it never explains what governance or the Shang dynasty is, and each section adds only framework-specific guidance Claude would not already know, matching the lean/efficient anchor.

Although this is an instruction-only skill with no code, the guidance is concrete and specific (identify wise elders, ask why the former state prospered and fell, select officials with demonstrated "驯行"), which the rubric rewards as actionable without penalizing the absence of code.

Five explicitly sequenced steps are followed by a Verification section with concrete checklist items (confirm elders were consulted, validate vices are avoided, check officials selected for virtue), providing explicit validation checkpoints.

This is a short (~50-line), single-purpose skill with no external references and well-organized sections (Overview, Core Principles, Key Warnings, Expected Outcomes, Verification), which the rubric's simple-skills note allows to score 3 without separate reference files.

The description enumerates multiple concrete actions — "seek local wisdom, study prior regime failures, practice benevolent rule, establish legal frameworks, and appoint virtuous officials" — matching the score-3 anchor of listing multiple specific actions.

It explicitly answers both what (the five governance actions) and when ("Use when establishing governance over newly conquered or acquired territory"), matching the score-3 anchor requiring both an explicit what and an explicit trigger.

It opens with a natural "Use when establishing governance over newly conquered or acquired territory" trigger, but the trigger terms are a narrow niche users would rarely verbalize, missing common variations; this is closer to 'some relevant keywords but missing common variations' than to broad natural-term coverage.

The niche — ruling newly conquered territory per Zhou Gong's framework — is highly distinct with triggers unlikely to fire for unrelated skills, matching the clear-niche anchor.
