Lean body that assumes Claude's competence: it skips basic image-generation explanation and devotes tokens to a copy-paste prompt spine, a similarity dial, and a validation checklist rather than padding.

Provides a fully executable prompt-spine template with named placeholders, a concrete distinct-brand matrix table, a targeted V2 revision instruction, and explicit file-naming and save rules.

Clear sequence (Start correctly -> Set the similarity dial -> Extract visual DNA -> Build matrix -> Write one prompt per brand -> Validate -> Save and hand off) with an explicit validation checklist and a feedback loop: "If one check fails, iterate with one targeted change and re-inspect."

SKILL.md is an overview with one-level-deep references that are real and clearly signaled: [references/example-prompts.md] (verified present, with named brand patterns) and assets/examples/ (verified, 5 images) flagged as optional visual aids.

Lists multiple concrete actions: "Generate multiple original brand campaign worlds from a supplied visual reference while controlling how close the new work feels without copying protected signature elements," plus inspired alternatives, multi-brand visual families, closer V2s, and exact wordmarks.

Answers both what (generate original brand worlds controlling similarity) and when via an explicit "Use when a user provides..." clause listing concrete scenarios.

Natural user phrasing is well covered: "brand identity image, poster, editorial campaign, moodboard, or generated concept" and triggers like "inspired alternatives," "closer-to-reference V2," and "exact wordmarks inside images."

Occupies a clear niche (reference-inspired brand campaign worlds with an originality/similarity dial) with distinctive triggers unlikely to fire for unrelated skills.
