handdrawn-schematiclisted

# Hand-Drawn Schematic Turn any schema (a concept, pipeline, architecture, algorithm, or mechanism) into a single friendly hand-drawn whiteboard illustration on a **pure white background**: wavy marker strokes, numbered panels flowing left to right, chunky chalk-style arrows, and short hand-written notes drawn beside the shapes. Every label, number, and equation is lettered by the same hand into the one drawing, so it reads like a research postdoc's explainer sketch for a small-group talk. By default this skill **renders a PNG** with the bundled `codex` image_generation tool (ChatGPT OAuth, no API key). When codex is not available it falls back to emitting the finished prompt so the user can paste it into any image generator. ## When to use - "Draw a hand-drawn schematic of how X works" - "Make a whiteboard-sketch figure explaining this pipeline / architecture" - "Sketch a doodle-style diagram of this algorithm" - "이 개념/구조 손그림 도식으로 그려줘" / "화이트보드 스타일 개념도 만들어줘" Do NOT use for: - Real data plots (matplotlib, seaborn, plotly) → `scienceplot-py` (publication `science`+`nature` style) or `xkcd-py` (sketch-style matplotlib from data). - A multi-style prompt-only composer across six looks (Editorial Magazine, Engineering Blueprint, Swiss Minimalist, Dark Tech/Neon, Scientific Poster) → `wide-slide-illustrator`. - The paired method + results infographics inside a paper walkthrough → `journal-club-review` (this skill is the reusable single-figure generator extracted fro
