Art Direction for AI Image Gen: img-gen-taste

Where this fits

You're building an agent that generates product shots for an e-commerce client. The first prompt returns a generic studio photo with flat lighting—nothing like the brand's warm, editorial aesthetic. You need a way to translate a vague brief into a precise visual direction before hitting the generator. img-gen-taste fills that gap: it gives your agent a set of curated style cards—reusable visual grammars distilled from real Open Image Prompts—so it can choose a direction, refine the prompt, and produce consistent, on-brand results without manual prompt engineering.

Why agents benefit

• Routes requests intelligently: The skill reads a user's subject, mood, and constraints, then loads only the relevant style card (e.g., product-advertising.md for commercial stills) instead of dumping all 39 references into context.
• Produces compact creative specs: It converts a vague request into a tight spec that includes lighting, composition, color palette, and texture—ready to be merged into a final generation prompt.
• Improves existing prompts: When a generation comes back weak, the agent can compare it against a style card and suggest targeted adjustments (e.g., "shift to soft directional light and add film grain").
• Translates images into prompts: Given a reference image, the skill extracts the underlying visual grammar and maps it to the closest style card, enabling style transfer without copying the original subject.
• Stays generator-agnostic: It focuses on art direction, not generator-specific syntax, so the same spec works across DALL·E, Midjourney, or Stable Diffusion with only minor syntax tweaks.

Practical scenarios

Product photography for a new launch

A user asks for "a premium feel" for a skincare bottle. The agent loads product-advertising.md, identifies the desired mood (clean, minimal, high-key), and produces a spec: "soft box lighting from upper left, white seamless background, subtle reflection on glass, shallow depth of field." The final prompt yields a catalog-ready shot.

Reviving a flat portrait

A portrait generation comes out too sharp and clinical. The agent reads portrait-photography.md, notices the card suggests natural window light and a shallow aperture, and revises the prompt to "golden hour through a sheer curtain, creamy bokeh, warm skin tones."

Exploring style alternatives for a food brand

The user can't decide between rustic and modern. The skill loads food-drink.md and presents two distinct creative specs: one with overhead flat lay and natural shadows, another with dramatic side lighting and a dark slate background. The user picks one, and the agent generates accordingly.

Add it to your agent workflow

Install the skill with npx:

npx skills add NanmiCoder/open-image-prompts --skill img-gen-taste

Then in your agent's tool definition, point it to the skill's routing logic. For example, when a user requests a product image, the agent will read references/product-advertising.md and output a structured spec like:

Subject: ceramic mug
Mood: warm, handmade
Lighting: diffused side window light
Composition: 3/4 angle, shallow depth of field
Palette: terracotta, cream, soft browns
Texture: matte, slight grain

Compare before adopting

Before committing, evaluate how img-gen-taste stacks up against alternatives like raw prompt libraries or generic style guides. Check if the 39 cards cover your most common use cases (product, portrait, food, craft—yes, but what about architecture or fashion?). Look at the maintenance freshness: the underlying Open Image Prompts repo is active, but style trends shift. Also consider workflow fit: if your agent already has a strong prompt-engineering layer, this skill may be redundant; if it lacks art direction, it's a clear win.

Why it is worth tracking

With 224 stars and an active author, img-gen-taste shows community momentum and a practical design—it's not just a prompt dump but a structured decision layer. Track it if you're building agents that need to produce visually consistent output across multiple generations. It's worth evaluating when you notice your image prompts are hit-or-miss, or when clients start demanding specific aesthetics.
