  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

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

  1. Identify task type (text-to-image, edit, or multi-reference).
  2. Ensure GEMINI_API_KEY is available (env or stored in .env), then use the Python SDK. This will make network requests to the Gemini API
  3. Choose model + output (response_modalities=["IMAGE"] if image-only) and run. Generation can take ~30 seconds; allow 30–60 seconds before retrying.
  4. Save returned images with part.as_image(); if none, report a clear error.

  • references/python.md for Python SDK usage

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.
