gemini-imagegen
This skill should be used when generating and editing images using the Gemini API (Nano Banana Pro). It applies when creating images from text prompts, editing existing images, applying style transfers, generating logos with text, creating stickers, product mockups, or any image generation/manipulation task. Supports text-to-image, image editing, multi-turn refinement, and composition from multiple reference images.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Gemini Image Generation (Nano Banana Pro) Generate and edit images using Google's Gemini API. Use `op run -- uv run ...` to run Python scripts. ## Default Model | Model | Resolution | Best For | |-------|------------|----------| | `gemini-3-pro-image-preview` | 1K-4K | All image generation (default) | **Note:** Always use this Pro model. Only use a different model if explicitly requested. ## Quick Reference ### Default Settings - **Model:** `gemini-3-pro-image-preview` - **Resolution:** 1K (default, options: 1K, 2K, 4K) - **Aspect Ratio:** 1:1 (default) ### Available Aspect Ratios `1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9` ### Available Resolutions `1K` (default), `2K`, `4K` ## CLI Scripts Ready-to-use scripts for common tasks. All scripts are in the `scripts/` directory. ### Generate Image from Text ```bash op run -- uv run scripts/generate.py "A sunset over mountains" -o sunset.jpg op run -- uv run scripts/generate.py "A minimalist logo" --aspect 1:1 --size 2K -o logo.jpg ``` Options: - `-o, --output`: Output file path (default: output.jpg) - `--aspect`: Aspect ratio (1:1, 16:9, 9:16, etc.) - `--size`: Resolution (1K, 2K, 4K) ### Edit an Existing Im

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill gemini-imagegen --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.
