Digitizes handwritten scanned notes, PDFs, or images into structured professional documents. Use this skill whenever a user uploads a photo, scan, PDF, or image containing handwritten content — notes, diagrams, architecture sketches, plans, tables, flowcharts, lists — and wants it transcribed, organized, or converted into clean digital output. Triggers include: "digitize my notes", "convert this scan", "transcribe my handwriting", "turn this into a doc", "OCR this", "clean up my notes", "my handwritten PDF", "my photo of notes", or when the user uploads any image/PDF and asks for markdown, Excel, or PDF output. Always produce ALL THREE outputs (Markdown with Mermaid diagrams, Excel, and PDF) unless the user explicitly asks for fewer. The Mermaid diagrams must faithfully reconstruct any hand-drawn diagrams, entity maps, flowcharts, or relationship sketches exactly as drawn — not as a generic interpretation.

Use when someone asks "why is my async code slow", "gather or create_task", "how do I run these requests concurrently", "my FastAPI endpoint blocks everything", or is converting sync Python to asyncio. Do NOT use for general pandas or data-analysis performance - use pandas-expert instead - and do NOT use for API endpoint design itself - use api-design instead.
