description	This skill should be used for Python scripting and Gemini image generation. Use when users ask to generate images, create AI art, edit images with AI, or run Python scripts with uv. Trigger phrases include "generate an image", "create a picture", "draw", "make an image of", "nano banana", or any image generation request.

Nano Banana Skill

Python scripting with Gemini image generation using uv. Write small, focused scripts using heredocs for quick tasks—no files needed for one-off operations.

Choosing Your Approach

Quick image generation: Use heredoc with inline Python for one-off image requests.

Complex workflows: When multiple steps are needed (generate -> refine -> save), break into separate scripts and iterate.

Scripting tasks: For non-image Python tasks, use the same heredoc pattern with uv run.

Writing Scripts

Execute Python inline using heredocs with inline script metadata for dependencies:

uv run - << 'EOF'
# /// script
# dependencies = ["google-genai", "pillow"]
# ///
from google import genai
from google.genai import types

client = genai.Client()

response = client.models.generate_content(
    model="gemini-3-pro-image-preview",
    contents=["A cute banana character with sunglasses"],
    config=types.GenerateContentConfig(
        response_modalities=['IMAGE']
    )
)

for part in response.parts:
    if part.inline_data is not None:
        image = part.as_image()
        image.save("tmp/generated.png")
        print()
EOF
