What it does

Generates and edits high-quality images using Google's Gemini 3 Pro Image model. It covers creating images from text prompts, editing existing images with natural language instructions, multi-turn iterative refinement, batch generation, and reference-based generation to maintain style across images. It supports up to 4K resolution, multiple aspect ratios, reference images, and advanced prompting techniques for cinema-quality results.

How it works

  1. Configure API access by setting GEMINI_API_KEY in the environment.
  2. Use the provided scripts to perform tasks:
    • Test API connection with python scripts/test_connection.py --api-key YOUR_KEY or by exporting GEMINI_API_KEY and running python scripts/test_connection.py.
    • Generate an image from text with python scripts/generate_image.py "<prompt>" and optional flags like --aspect-ratio, --temperature, --output, and --filename.
    • Edit an existing image with python scripts/edit_image.py "<edit prompt>" input.jpg and optional flags such as --aspect-ratio, --temperature, --output, and --filename.
    • Use multi-turn editing by chaining successive edit_image.py calls, each building on the previous output.
    • Perform batch generation via a shell script or Python wrapper that calls generate_image.py multiple times with different prompts and output paths.
    • Use reference-based generation with generate_with_references.py by supplying a prompt and one or more reference images.
  3. Utilize core workflows including text-to-image generation, image edits, batch generation, and reference-based generation to meet varied image production needs.
  4. Adjust prompting following best practices for structure, cinematic language, layering, and iterative refinement.

When to use it

Use when you need professional-quality images from text prompts, need to edit or refine existing images with natural language instructions, perform batch variations, maintain style across multiple images using references, or troubleshoot Gemini image generation API integration.

What it can touch

  • Tools/scripts: scripts/test_connection.py, scripts/generate_image.py, scripts/edit_image.py, scripts/generate_with_references.py.
  • Environment: GEMINI_API_KEY as an environment variable.
  • Files touched by operations include output directories (e.g., ./output, ./campaign, etc.) and filenames provided via --filename.

Caveats

  • API keys and usage are governed by Gemini API terms and pricing, including per-image costs and rate limits outlined in the script bundle references.
  • Output quality and specific capabilities depend on prompt quality, input data, and chosen parameters (e.g., --temperature, --aspect-ratio).
  • Editing supports input formats JPEG, PNG, WebP for inputs and outputs as per API details.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill nano-banana-pro-tdimino-claude-code-minoan --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.
