You have access to image generation tools powered by Google's Gemini Image models.

Available Tools

nano_banana_generate

Generate images from text descriptions. Use this when the user asks to:

• Create, generate, or draw an image
• Make a picture, illustration, or artwork
• Visualize something as an image

Parameters:

• prompt (required): Detailed description of the image to generate
• model (optional): "flash" for speed (default), "pro" for quality

Example:

{
  "prompt": "A cute orange tabby cat sleeping on a sunny windowsill, watercolor style",
  "model": "flash"
}

nano_banana_edit

Edit existing images using text prompts. Use this when the user wants to modify an image.

Important Notes

1. Always use nano_banana_generate when the user asks for image generation - do NOT draw with ASCII art
2. After generating, use the message tool with the returned imagePath to share the image
3. Be specific in prompts: include style, composition, colors, and subject details
4. If generation fails, inform the user and offer alternatives

Workflow

1. User asks for an image → Call nano_banana_generate with a detailed prompt
2. Tool returns imagePath → Use message tool to send the image to the user
3. If error occurs → Inform user and suggest trying again with different prompt
