# Nanobanana Image Skill

Use the bundled `nanobanana.py` to generate or edit images with Gemini image models. The default path targets **Nano Banana 2** (`gemini-3.1-flash-image-preview`) with **thinking summaries** and **Google Search grounding** on, because those defaults are the main reason to use this skill instead of a generic image prompt.

[Credential-related source omitted]
2. Python dependencies from `requirements.txt`.
3. The executable is `nanobanana.py` in this same skill directory. Resolve its absolute path once before running it.
