ekr0/auto-kdp — reverse-engineered prompt

Build me a command line tool that helps me bulk publish and update paperback books on Amazon KDP using a spreadsheet and files on my computer.

I want to keep my books in a CSV, have shared defaults in a simple config file, and point the tool at a content folder where the manuscript PDFs live. The app should open a real browser and click through KDP like a human would, so it can sign in with my local browser profile, create or update a book, upload content, update pricing, publish, and scrape back things like IDs or ISBN when available. It should process books in order based on an action field, retry failed steps a couple of times, and write progress back to a new CSV after each step so I do not lose state.

Please include a dry run mode, a visible browser mode for testing, and a headless mode for real runs. Keep credentials local. It is fine if this only covers the supported KDP flows for print books, not every edge case. Look up current docs online if you need to.
