Nanobanana Image Generation

Overview

This skill now supports two modes:

• image mode Gemini or Nanobanana generation and editing through the official generateContent flow
• plot mode Exact Python or matplotlib rendering of publication-style figures from numeric data

Use image mode for mechanism figures, graphical abstracts, device schematics, style-matched redraws, and diagram-first work. Use plot mode for exact bar charts, trend curves, heatmaps, scatter plots, and multi-panel figures that must preserve numeric truth.

Runtime policy:

• Python is the required runtime for this skill and the canonical path for both image and plot workflows.
• scripts/generate_image.js is an optional parity CLI for environments that already use Node.js, not the required runtime baseline for registry gating.
