Conciseness

The body is lean and assumes competence: short sectioned steps with no padding or explanation of concepts Claude already knows, and every line earns its place.

Actionability

Concrete, specific guidance with real quantities (2,000 light cavalry, red flags, 10,000 troops, riverside position), but it is instruction-only with no executable code or commands — acceptable for an instruction skill, leaving a minor gap versus copy-paste-ready material.

Workflow Clarity

Six clearly sequenced steps are followed by a dedicated 'Verification' section with three explicit checkpoints (intelligence verified, cavalry positioned before main deployment, feigned defeat convincing enough to empty the camp), providing the validation/feedback loop a risky military operation needs.

Progressive Disclosure

A self-contained, well-organized skill under 50 lines with clear section headers and no need for external references — the simple-skill exception applies, so well-organized single-file structure earns a 5.

Specificity

Names concrete actions ('position troops in death ground', 'hidden cavalry to capture the enemy camp') rather than vague language, though the actions are high-level military maneuvers rather than granular steps.

Completeness

Explicitly answers both what ('Applies Han Xin's 井陉之战 tactic: position troops... with hidden cavalry to capture the enemy camp') and when ('Use when commanding an inferior force that needs maximum motivation against a superior enemy') with concrete trigger phrasing.

Trigger Term Quality

Includes an explicit 'Use when commanding an inferior force that needs maximum motivation against a superior enemy' trigger, but the phrasing is domain-jargon and lacks the everyday synonyms a user would naturally say.

Distinctiveness Conflict Risk

Occupies a clear, narrow niche (Han Xin's back-to-water death-ground tactic) with highly specific triggers, making conflict with other skills minimal.
