Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
What it does
Instructs the agent to generate prompts for Gemini to create conceptual images for game development, covering concept art, UI mockups, character designs, environments, and visual references. Provides structure, style modifiers, subject templates, lighting, camera, and iteration guidance to produce asset concepts.
How it works
Specifies a prompt structure template and multiple style modifiers by game type, plus templates for Subject Concepts (Character, Environment, UI, VFX/Particle, Item/Prop). Includes example prompts and guidance on lighting keywords, camera/composition keywords, and quality boosters. Contains specific iteration workflow steps (First Pass, Refine, Final) and game-specific prompt examples. Also provides multi-view/model reference grids and an orthographic view template for Roblox-styled assets. The content emphasizes concrete phrasing, scene composition, and game context in prompts using quoted examples like:
- [STYLE] [SUBJECT] [ACTION/POSE] [ENVIRONMENT] [LIGHTING] [CAMERA] [GAME CONTEXT]
- Example prompts such as:
- "Low-poly stylized 3D render of a treasure chest, slightly open with gold coins spilling out, on a stone dungeon floor, warm torchlight from the left, isometric view, Roblox pet simulator style, clean topology, vibrant colors"
- Style modifiers like:
- "low-poly blocky style"; "Roblox-inspired aesthetic"; "cube voxel art"; "soft gradient shading"; "anime cel-shaded"; "semi-realistic 3D render"; "16-bit pixel art"
- Lighting keywords table and camera/composition keywords table
- Iteration prompts and 3x3 model/reference prompts for Roblox-style assets
When to use it
Use when you need to craft precise prompts that guide Gemini in generating game art concepts. Applicable to creating concept art, UI mockups, character designs, environment sketches, or visual references. Use the prompts to clearly define style, composition, lighting, and game context and to drive iterative refinement.
What it can touch
- Reads and writes prompt text according to the templates and examples
- No executable tools or file operations are specified beyond formulating prompts
Caveats
- License and tool usage are stated as MIT and allowed tools Read/Write/Edit, but the skill itself instructs about prompt construction rather than running code or accessing external systems
- No guarantees about Gemini output quality; prompts only describe how to request content

What does the gemini-image-prompting skill do?
Patterns for prompting Gemini to generate conceptual images for game development. Use when creating concept art, UI mockups, character designs, environment sketches, or visual references.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill gemini-image-prompting --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
