By name: image-generation description: Gemini image generation and editing skill for text-to-image, image-to-image edits, multi-reference composition, and Google Search grounding. Use when creating or modifying images via Gemini (default model gemini-3-pro-image-preview) with the Python SDK.
Image Generation with Gemini
Use this skill when the user asks to generate or edit images with Gemini using the Python SDK. Default to gemini-3-pro-image-preview, and mention gemini-2.5-flash-image only as an optional faster/cheaper alternative.
Workflow
- Identify task type (text-to-image, edit, or multi-reference).
- Ensure
GEMINI_API_KEYis available (env or stored in.env), then use the Python SDK. This will make network requests to the Gemini API - Choose model + output (
response_modalities=["IMAGE"]if image-only) and run. Generation can take ~30 seconds; allow 30–60 seconds before retrying. - Save returned images with
part.as_image(); if none, report a clear error.

Response handling (Python SDK)
Use part.as_image() to access image outputs and save them. If no image parts are returned, surface a clear error and suggest checking the API key, model name, and response modalities.
Timing note
Image generation may take around 30 seconds. When running commands via the shell tool, set a longer timeout (e.g., 60–120 seconds) to avoid premature timeouts.
