Scientific Schematics skill: what it does and how to install it

What it does. Generates PNG schematics from natural-language descriptions using Nano Banana 2, then sends each image to Gemini 3.6 Flash for quality scoring and regenerates only when it misses the threshold. A Python command supports document-type thresholds, versioned outputs and review logs.

When to use it. For neural-network architectures, flowcharts, biological pathways, system diagrams, circuits and other scientific figures. It does not produce vector files or control DPI, so print conversion and visual checking remain downstream.
