The body is mostly lean and bullet-driven, but the 'Advantages' and 'Expected Outcomes' sections largely restate each other and the Overview (e.g., 'Enemy cannot concentrate defenses' vs 'Enemy forces dispersed across multiple fronts'; 'Failure of one column doesn't doom the campaign' vs 'At least partial forces arrive at target'), so not every token earns its place.

Concrete procedural steps with a fully worked example — named routes ('Guiyang via Hui River', 'Yuzhang via Hengpu') and specific force-type assignments ('Regular troops for main routes', 'Conscripted prisoners for support routes', 'Naval forces where waterways available') — give actionable guidance for an instruction-only skill.

A clearly numbered five-step sequence is paired with an explicit 'Verification' checklist ('Confirm all viable approach routes...', 'Validate that each column has appropriate troop types...', 'Check that convergence timing accounts for different route difficulties...'), providing validation checkpoints.

The skill is under 50 lines with no external references needed and no bundle files present; the content is well-organized into clearly headed sections (Overview, Planning Steps, Advantages, Expected Outcomes, Verification), satisfying the simple-skill anchor.

Lists multiple concrete actions — 'Maps multiple approach routes, assigns forces by type (regular, conscript, naval), sets convergence points, and accepts partial column failure' — matching the score-3 anchor for several specific concrete actions.

Explicitly answers both: the 'what' (maps routes, assigns forces, sets convergence, accepts partial failure) and the 'when' via an explicit 'Use when planning multi-column campaigns against distant targets...' trigger clause.

Natural domain terms a user would actually say — 'multi-column campaigns', 'distant targets', 'Nanyue conquest', 'convergence' — give good coverage rather than jargon or generic phrasing.

The multi-route military convergence niche is highly specific with distinct triggers, making it unlikely to fire for unrelated skills; it does not overlap with generic planning skills.
