When the user wants to create, generate, edit, or optimize images for marketing — blog heroes, social graphics, product mockups, profile banners, listing visuals, or brand assets. Also use when the user mentions 'AI image generation,' 'generate an image,' 'create a graphic,' 'product mockup,' 'hero image,' 'social media graphic,' 'banner image,' 'cover photo,' 'profile banner,' 'listing screenshot,' 'Flux,' 'Flux Kontext,' 'Midjourney,' 'DALL-E,' 'GPT Image,' 'ChatGPT Images,' 'Ideogram,' 'Gemini image,' 'Nano Banana,' 'Recraft,' 'Stable Diffusion,' 'Canva,' 'Figma,' 'image optimization,' 'compress images,' 'WebP,' or 'OG image.' Use this for general-purpose marketing image creation and optimization. For paid ad image creative and platform-specific ad specs, see ad-creative. For video production, see video.

Quality

Content

68%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized, largely actionable reference guide with strong decision tables and executable optimization commands. The main gaps are a redundant questions section, batch image operations lacking validation/backup steps, and heavy inline detail that could be split into more reference files.

Suggestions

Add validation/backup guidance to the batch optimization commands (e.g., test on a copy first, verify output with a size check, or note that jpegoptim modifies files in place) to raise workflow clarity.

Remove the 'Task-Specific Questions' section, which duplicates the 'Before Starting' context-gathering questions almost verbatim.

Include one concrete generation example (e.g., a curl or SDK call for Gemini or Flux) in the AI Image Generation section so the primary workflow is executable without opening the reference file.

DimensionReasoningScore

Conciseness

The body is information-dense (spec tables, model comparisons, copy-paste commands) and does not explain concepts Claude already knows. It is not a 5 because there is genuine redundancy: the "Task-Specific Questions" section (lines 321-328) repeats the "Before Starting" context questions (lines 17-32), and a few lines like "Every image on your site affects page speed, which affects SEO and conversions" are padding that could be trimmed.

4 / 5

Actionability

Concrete, executable guidance is present throughout — bash commands (cwebp, mogrify, jpegoptim), copy-paste meta tags, exact pixel dimensions, prompt patterns, and a decision tree. It is not a 5 because the core AI-generation workflow stops at "Generate with AI — use Flux or Gemini" without a concrete API call example (deferred entirely to the reference file), leaving minor gaps in the most common path.

4 / 5

Workflow Clarity

Workflows are clearly numbered and sequenced (blog hero 1-4, social 1-4, mockups 1-4, banners 1-5), but the batch optimization commands ("mogrify -format webp -quality 80 *.png", "jpegoptim --max=80 --strip-all *.jpg" — the latter modifies originals in place) run on all matching files with no backup, dry-run, or verification step. Per the rubric, missing validation in batch/destructive operations caps workflow clarity at 3.

3 / 5

Progressive Disclosure

Structure is good: a well-signaled one-level-deep reference ("For detailed prompting guides per model, see references/ai-image-prompting.md") that exists in the bundle, and clearly sectioned inline content. It is not a 5 because substantial detail (the per-model comparison rows, platform size tables, optimization specifics) is inlined in SKILL.md where the anchor expects an overview with content appropriately split across references — only one reference file exists for a ~340-line body.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete actions and asset types, an explicit use-when clause with an extensive natural trigger list, and explicit de-confliction pointers to related skills. Third-person voice is maintained throughout.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — "create, generate, edit, or optimize images" — and enumerates concrete asset types ("blog heroes, social graphics, product mockups, profile banners, listing visuals, or brand assets"), matching the comprehensive-coverage anchor. It is not a 4 because coverage of the domain's actions (create/edit/optimize) is complete rather than having minor gaps.

5 / 5

Completeness

It explicitly answers "what" ("create, generate, edit, or optimize images for marketing" with asset types) and "when" ("When the user wants to..." and "Also use when the user mentions..." with a long trigger list). This is the exact structure of the 5 anchor example; the "when" is explicit, not weakly implied (which would be a 3).

5 / 5

Trigger Term Quality

Trigger coverage is comprehensive and includes natural user phrases ("generate an image," "create a graphic," "hero image," "cover photo"), model/tool synonyms ("Flux," "Midjourney," "DALL-E," "Nano Banana," "Canva," "Figma"), and technical terms ("WebP," "OG image," "compress images"). This matches the 5 anchor's inclusion of synonyms and tool-specific variants.

5 / 5

Distinctiveness Conflict Risk

The niche is clear (marketing images) and it includes explicit boundary guidance — "For paid ad image creative and platform-specific ad specs, see ad-creative. For video production, see video." — reducing conflict with the closest neighboring skills. Mention of general tools (Canva, Figma) creates only minimal overlap risk, consistent with the 5 anchor.
