Mostly efficient domain-specific guidance, but the dimension table is duplicated between Workflow step 5 and the Image Gen Prompt, and the option-ordering rules are restated across the Workflow, rules list, and Output sections — tightening this repetition would lift it to 3.

Provides a copy-paste-ready Image Gen prompt, exact dimension values (390x844, 1440x1024, etc.), concrete folder paths to probe, and verbatim selection-message text — fully executable guidance.

An 8-step sequence with explicit validation checkpoints (brief-satisfied gate before generation, access-gap stop-and-ask, 'retry missing generation' before the selection message) plus a feedback loop for revisions.

Sections are clearly organized and references to sibling skills (index, user-context, get-context, image-to-code) are one level deep and well-signaled, but the ~190-line body keeps the full Image Gen prompt and detailed rules inline rather than offloading them to reference files; no bundle files are present to verify against.

Lists multiple concrete actions — 'Generate image-based alternatives, remixes, or new design directions' — each naming a distinct output type rather than vague capability.

Explicitly answers both 'what' (generate image-based alternatives/remixes/new directions from a brief) and 'when' via the explicit 'Use when the user asks for...' clause.

Covers natural user phrasing — 'design variants, visual exploration, remixes, or image-generated approaches' — the terms a user would actually say when needing this skill.

Scoped to a Product Design brief with image-generation-specific triggers, giving it a clear niche unlikely to fire for unrelated image or code skills.
