Create publication-quality scientific diagrams using Nano Banana 2 AI with smart iterative refinement. Uses Gemini 3.6 Flash for quality review. Only regenerates if quality is below threshold for your document type. Specialized in neural network architectures, system diagrams, flowcharts, biological pathways, and complex scientific visualizations.
Why this skill is useful
Adds specific commands for generating high-quality scientific diagrams that the AI wouldn't reliably generate on its own.

What this skill does
Scientific Schematics and Diagrams Overview Scientific schematics and diagrams transform complex concepts into clear visual representations for publication. This skill uses Nano Banana 2 AI for diagram generation with Gemini 3.6 Flash quality review. How it works: Describe your diagram in natural language Nano Banana 2 generates publication-quality images automatically Gemini 3.6 Flash reviews quality against document-type thresholds Smart iteration: Only regenerates if quality is below threshold Publication-ready output in minutes No coding, templates, or manual drawing required Quality Thresholds by Document Type: Document Type Threshold Description --------------- ----------- ------------- journal 8.5/10 Nature, Science, peer-reviewed journals conference 8.0/10 Conference papers thesis 8.0/10 Dissertations, theses grant 8.0/10 Grant proposals preprint 7.5/10 arXiv, bioRxiv, etc. report 7.5/10 Technical reports poster 7.0/10 Academic posters presentation 6.5/10 Slides, talks default 7.5/10 General purpose Simply describe what you want, and Nano Banana 2 creates it. All diagrams are stored in the figures/ subfolder and referenced in papers/posters. What the output is: a raster PNG at whatever resolution the image model returns. This skill has no vector path and no DPI control — if a journal demands PDF, EPS, or 300 dpi TIFF, convert the PNG downstream and check the result at final print size. Quick Start: Generate Any Diagram Create any scientific diagram by simply describing it. Nano Banana 2 handles everything automatically with smart iteration: What happens behind the scenes: 1. Generation 1: Nano Banana 2 creates initial image following scientific diagram best practices 2. Review 1: Gemini 3.6 Flash evaluates quality against document-type threshold 3. Decision: If quality >= threshold → DONE (no more iterations needed!) 4. If below threshold: Improved prompt based on critique, regenerate 5. …
