✨ Features

• Multi-format input — reads PDFs (with images/diagrams), PPTX (text + embedded media), Markdown, plain text, and images (PNG/JPG)
• Browser-based configuration — clean UI to set paper size, columns (2–6), font, margins, color scheme, detail level, and select which files to include
• 5 color schemes — Classic, Ocean, Forest, Sunset, Mono — all designed for print readability
• Extreme density — fills every inch of the page with color-coded, abbreviated, formula-heavy content
• Smart organization — groups by topic hierarchy, not source file order; prioritizes exam-focus topics
• Iterative editing — browser-based editor where you describe changes in plain English (or attach images); Claude applies them live
• Image-aware — upload screenshots of formulas or diagrams during editing; Claude sees and incorporates them
• XeLaTeX-ready — output compiles directly in Overleaf with custom fonts

🚀 Quick Start

Install

npx skills add https://github.com/Evan715823/cheatsheet-generator-skill

Then install Python dependencies:

pip install flask python-pptx pymupdf

Use

1. cd into a folder containing your course materials (PDFs, slides, notes)
2. Run Claude Code and type:

   generate a cheatsheet for my exam based on the <your material files>
   

   Or use the slash command directly:

   /cheatsheet-generator
   

3. A browser window opens — configure your cheatsheet layout, select files, pick a color scheme
4. Claude reads all materials and generates cheatsheet.tex
5. Another browser window opens — request edits in natural language until you're happy
6. Upload cheatsheet.tex to Overleaf, compile with XeLaTeX

🔧 How It Works

Phase 1 — Configure

A local Flask server launches and opens a browser form. You configure layout (paper, columns, font, margins), content settings (detail level, proofs, examples), select a color scheme, and pick which files to include. Submitting writes .cheatsheet_config.json and the server exits.

Phase 2 — Generate

Claude reads every selected file:

• PDFs — read directly (text + images via multimodal vision)
• PPTX — extracts text via python-pptx + all embedded images
• Markdown/Text — read directly
• Images — read directly (Claude is multimodal)

Then generates a complete cheatsheet.tex using the base template with your config values. Content is organized by topic, color-coded with semantic commands (\concept{}, \process{}, \category{}, \important{}), and packed to fill the entire page.

Phase 3 — Edit

Another Flask server launches with a split-panel editor:

• Left: LaTeX source with syntax highlighting + optional PDF preview
• Right: natural language edit requests + image upload + change history

The server uses a blocking HTTP protocol — no polling, no file watching. When you submit a request, Claude reads the current .tex, applies your change, and posts the result back. Repeat until satisfied, then click Done.

💡 Tips

• Compile with XeLaTeX in Overleaf (not pdfLaTeX) — required for fontspec custom fonts
• Exam focus field is powerful — write "focus on: gradient descent, bias-variance tradeoff" and those topics get more space
• Image upload in editor — screenshot a formula from your textbook, paste/drag it into the editor, and ask Claude to add it
• Multiple cheatsheets — run the skill in different folders for different courses; each gets its own cheatsheet.tex
• Install latexmk and pdftoppm for live PDF preview in the editor (optional)
