Ethan's tablet is used for reading briefs and reviewing commits, but never for originating tools — every one of his ~400 custom tools started at a keyboard. This watches ~/Tablet/ for handwritten notes in a new 'sketches' folder, OCRs them, and turns any note that reads like a tool idea into a real scaffolded script in ~/bin with a stub, usage block, and matching .test.sh, then emails him the path. Ideas jotted on e-ink while away from the desk become executable stubs before he sits down.
Create ~/bin/sketch-to-tool: inotifywait (or a 2-min cron) on ~/Tablet/sketches/*.{png,pdf}; for each new file, run Claude with a prompt to OCR and classify ('is this a tool idea? if so emit {name, one-line purpose, inputs, likely integrations}'); if yes, write ~/bin/
