The body is lean and bullet-driven with no padding or explanations of concepts Claude already knows; every section earns its place, matching the 'lean and efficient' anchor.

For an instruction-only skill it gives concrete, specific guidance with real examples — 'Enter the enemy camp with elite cavalry', 'Execute those attempting to escape (e.g., 8,000 executed)', 'Use official transport (传)' — so absence of code is not penalized.

The eight steps are clearly sequenced and a Verification checklist exists, but for destructive/batch operations the rubric expects inline checkpoints and error-recovery feedback loops; validation is only end-of-process with no 'if X fails, do Y' loop, fitting the 'steps listed but validation gaps' anchor rather than the level above.

The skill is under 50 lines, needs no external references, and is well-organized into Overview, Steps, Expected Outcome, and Verification sections, satisfying the simple-skill exception for a top score.

The description lists multiple concrete actions — 'credibility assessment, dissenter neutralization, leadership escort, population resettlement as 属国, and title conferral' — matching the anchor for listing several specific concrete actions.

It clearly answers both what ('Covers credibility assessment...') and when ('Use when processing the surrender...') with an explicit trigger clause, matching the top anchor.

It has an explicit 'Use when processing the surrender of tens of thousands of enemy troops' trigger with relevant natural terms, but offers only a single phrasing and lacks common variations, fitting the 'some relevant keywords but missing common variations' anchor.

The scenario is highly niche — mass enemy surrender modeled on Huo Qubing's precedent — with distinct triggers unlikely to overlap with other skills, matching the 'clear niche with distinct triggers' anchor.
