concept-explainerlisted

# concept-explainer — Kind, Rigorous, Visualization-Heavy Explanations Produce a single explanation document that walks a named audience through a specific concept **without logical leaps** and **without sacrificing mathematical rigor**. Equations carry their weight, every symbol is defined, every step in a derivation names the rule it applies, and visualizations appear wherever they shorten the gap between a formula and an intuition. The skill writes: ```text <out-dir>/ # <YYYYMMDD>_<concept-slug>, e.g. 20260728_lagrangian-mechanics ├── explanation.md # the document (language follows user's request) ├── plots/ # matplotlib scripts + their rendered PNGs │ ├── *.py │ └── *.png └── schematics/ # OPTIONAL — only when conceptual diagrams help ├── *_prompt.md # copy-pasteable wide-slide-illustrator prompts └── *.png # rendered images (user fills these in, or codex-image) ``` `<out-dir>` is `<YYYYMMDD>_<concept-slug>`: the day the directory is created (`date +%Y%m%d`) followed by the kebab-case concept slug. Alphabetical order then equals chronological order in any folder that collects explanations. After the document is complete, the skill invokes `md2pdf-typora` to produce `<out-dir>/explanation.pdf`, then mirrors the explanation (markdown, PDF, plots, schematics) into `~/Dropbox/ConceptExplainer/<Topic>/<out-dir>/`, organised by topic. The archive folder keeps the same name as the
