The body is lean and assumes competence — it never explains what a general or military justice is, and every section (Overview, Steps, Decision Principle, Expected Outcome, Verification) earns its place; not level 2 because there is no padded or unnecessary explanation.

Steps give concrete, specific guidance for an instruction-only skill — named roles ("legal officers (正), secretaries (长史), and advisors (议郎)") and concrete actions ("Escort the accused to the sovereign for final judgment"); not level 2 because key details are present rather than pseudocode-like or missing.

A clear five-step sequence is followed by an explicit Verification section functioning as a checklist (confirm arguments heard, validate circumstances investigated, check escalation to higher authority), matching the level-3 anchor with explicit validation steps.

The skill is under 50 lines, single-purpose, and needs no external references; it is organized into well-labeled sections, which per the simple-skills scoring note earns a 3 without bundle files.

Lists multiple concrete actions — "Convenes advisors, weighs strict versus lenient views, and defers to higher authority rather than unilateral execution" — rather than vague language; not the level-2 single-domain anchor because it enumerates several specific procedural actions.

Explicitly answers both "when" ("Use when deciding the fate of a defeated general...") and "what" (convenes advisors, weighs views, defers to higher authority) with an explicit Use-when trigger, matching the level-3 anchor.

The trigger "Use when deciding the fate of a defeated general who returns after losing their forces" has relevant natural keywords but only a single trigger path with no common variations or synonyms, matching the level-2 anchor rather than the broad coverage of level 3.

The niche is highly specific (military justice for a defeated returning general) with distinct triggers unlikely to overlap with other skills, matching the level-3 clear-niche anchor.
