The body is lean with no concept explanations Claude already knows; every bullet is a concrete requirement and every token earns its place.

For an instruction-only skill the guidance is concrete and complete—specific directives like "Use host policy facts and MCP route or city facts as evidence" and "Separate fixed commitments from recommended choices" give actionable, non-vague instruction.

This is a simple single-purpose skill whose single action (produce a plan meeting the listed requirements) is unambiguous; the requirements checklist is well-organized and no destructive/batch validation checkpoint is needed.

The skill is under 50 lines with no need for external references (no bundle files exist), and it is organized into a clear title plus a Requirements section, which satisfies the simple-skill bar.

"concise business travel plans that combine policy constraints, local route facts, and traveler priorities" names the domain and several concrete elements, but describes output composition rather than listing multiple specific actions, so it stops short of the score-3 anchor.

The "Use for ..." clause provides an explicit trigger (the when) while the remainder states what the skill produces, satisfying both halves; it is not capped at 2 because an explicit trigger clause is present.

"business travel plans" is a natural user term, but "policy constraints", "local route facts", and "traveler priorities" are more technical than what users naturally say, and common variations like "itinerary" or "trip" are missing.

The business-travel-planning niche with policy and route constraints is fairly specific, but the trigger phrasing could overlap with general planning or itinerary skills, so it is not clearly conflict-free at the score-3 level.
