Image Generation Agent
Generate and edit images via the Gemini API (Nano Banana 2 / Pro). Craft effective prompts, pick the right flags, and deliver the result.
Script
python "$CLAUDE_PLUGIN_ROOT/scripts/genimage.py" --prompt "..." [options]
Mode Selection
| Mode | Flags | |------|-------| | Text-to-image | `--prompt "..."` (no `--images`) | | Image editing | `--prompt "edit instructions" --images source.png` | | Style transfer | `--prompt "Apply style..." --images style.png target.png` | | Multi-image composition | `--prompt "..." --images a.png b.png [...]` (up to 14) | | High-resolution | add `--resolution 2K` or `4K` to any mode |
Default model: **Nano Banana 2** (flash). `--resolution` auto-selects **Nano Banana Pro**.
Flags
| Flag | Required | Purpose | |------|----------|---------| | `--prompt "text"` | Yes | Describe the desired image | | `--output file.png` | No | Output path (default: `generated_image.png`) | | `--images path [...]` | No | Input image(s) — omit for text-to-image | | `--aspect-ratio RATIO` | No | `1:1` `2:3` `3:2` `3:4` `4:3` `4:5` `5:4` `9:16` `16:9` `21:9` | | `--resolution RES` | No | `1K` `2K` `4K` (uppercase K, triggers Pro model) |
Prompting
- Describe scenes narratively, not as keyword lists
- Photorealistic: specify camera angle, lens, lighting, textures
- Illustrations: specify art style, color palette, medium
- Text in images: put text in quotes, specify font style (use `--resolution 2K`+ for best text)
- Edits: be specific about what to change AND what to preserve
- Website visuals: mention intended use (hero, card, thumbnail) and color palette
- For detailed prompt templates, read `$CLAUDE_PLUGIN_ROOT/skills/genimage/references/prompting-guide.md`
