Google Image Generation Skill
Generate images from text prompts using Google's Gemini API.
First-Time Setup (Once Per Context)
Run these commands once at the start of a session:
${CLAUDE_PLUGIN_ROOT}/scripts/check_env.sh
cd ${CLAUDE_PLUGIN_ROOT} && uv sync && cd -
If the environment check fails, the user needs to configure their API key.
Recommended: Create ~/.config/google-image-gen/.env with:
GOOGLE_AI_API_KEY=your_key_here
Get an API key from https://aistudio.google.com/apikey
Alternative: Export as environment variable: export GOOGLE_AI_API_KEY=your_key
Usage
Important: The plugin runs from its own directory. Use --cwd to ensure output files land in the user's project,
not the plugin cache.
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" <output_path> "<prompt>" [options]
Note: When the user specifies a path like output.png or images/photo.png, pass it as-is — the --cwd parameter
ensures it resolves relative to the user's project root.
Options
| Option | Short | Description |
|---|
--style | -s | Style template (.md file with {subject} placeholder) |
--ref | -r | Reference image for style (repeatable, max 14) |
--edit | -e | Edit existing image instead of generating |
--aspect | -a | Aspect ratio: 1:1, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 |
Examples
Simple Generation
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" output.png "A red apple on a wooden table"
Save to subdirectory
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" images/output.png "A red apple"
With Aspect Ratio
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" thumb.png "Mountain landscape" --aspect 16:9
Edit Existing Image
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" output.png "Change the sky to sunset" --edit input.png
With Reference Image
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" output.png "Same style but with a car" --ref reference.png
Multiple Variations
Generates numbered outputs (output_1.png, output_2.png, etc.):
ORIG_CWD="$(pwd)" && cd ${CLAUDE_PLUGIN_ROOT} && uv run python main.py --cwd "$ORIG_CWD" output.png "cat" "dog" "bird"
Workflow
- First use in context: Run setup commands (check_env.sh + uv sync)
- Generate images as needed
- Report output paths to user
Notes
- Paid API tier recommended (free tier has strict rate limits)
- Output directories are created automatically
- Default aspect ratio is 16:9
