The body is lean and tactical — terse bullets like "Always work inside the project's `assets/` directory" with no padding or concept explanations Claude already knows.

Concrete tool calls (GenerateImage, ViewImage, Delete), an ordered subject→style→framing prompt template with copy-ready example strings, and an explicit path convention make it fully actionable.

A clear generate→judge→regenerate loop is given, and the destructive Delete op is explicitly gated on user agreement, satisfying the checkpoint requirement for risky operations.

A short (~30 line), single-purpose skill with no bundle files, organized into three clear sections — meeting the simple-skill exception that allows a 3 with just well-organized sections.

Names three concrete actions — "Generate, view, and refine" — applied to a concrete domain (images), matching the anchor for multiple specific concrete actions.

The description clearly states what it does but contains no "Use when..." trigger clause — per the judging guidelines a missing explicit trigger clause caps completeness at 2.

Within the description field itself, only "images" is a natural term; the richer triggers (icons, illustrations, hero art, mockups) live in when_to_use rather than the description, leaving common variations uncovered.

Scoped to "images for the active project" it carves a clear niche with triggers unlikely to collide with unrelated skills, matching the distinct-niche anchor.
