Nano Banana Builder

Image generation and post-processing via two deterministic Python scripts (nano-banana-generate.py and nano-banana-process.py). Your job is prompt crafting and flag selection; the scripts handle all mechanical operations.

Instructions

1. Validate the environment

Before any generation call, confirm the API key is set. The scripts read GEMINI_API_KEY (or GOOGLE_API_KEY) from the environment and will fail without it. Checking this first avoids wasted time on API calls that will error immediately.

2. Choose the right script and subcommand

Translate user intent into the correct script call. Always call the scripts — never write inline PIL/sharp/image-processing code, because that duplicates tested logic and bypasses the deterministic pipeline.
