The body is lean and assumes Claude's competence—every line is specific directive guidance ("hit marks accurate to 0.1 seconds", "2.35:1 anamorphic widescreen, 85mm, T1.8") with no padding or explanation of concepts Claude already knows.

Though code-free, this instruction-only skill gives concrete, executable specifics: required hit-mark elements, enumerated camera moves, exact optical settings, and an explicit gore-language avoidance rule with preferred alternatives.

As a single-purpose, under-50-line skill it is well-organized into clear sections (Core Rules, Camera Rules, Asset Consistency, Optical Lock); the simple-skills carve-out applies and no destructive/batch operation requires validation checkpoints.

The skill is self-contained under 50 lines with no bundle files and no need for external references, so well-organized sections alone satisfy the progressive-disclosure bar.

The description enumerates multiple concrete capabilities—"15-second temporal slicing, exact hit marks, physical feedback, non-centered camera choreography, and cinematic impact readability"—rather than vague language, matching the 'lists multiple specific concrete actions' anchor.

It answers both 'what' (the enumerated capabilities) and 'when' via the explicit "Use for combat, chase, transformation..." trigger clause, satisfying the both-what-and-when anchor.

Natural user-facing terms ("combat, chase, transformation, impact-heavy, or high-kinetic action video") give good coverage of what a user would actually say, beyond jargon.

The niche is narrowly scoped to cinematic action hit-marking with distinctive triggers, making it unlikely to fire for unrelated skills.
