I just published an extensive review of the new feature, which is actually Claude Code Interpreter (the official name, bafflingly, is Upgraded file creation and analysis - that's what you turn on in the features page at least).
I reverse-engineered it a bit, figured out its container specs, used it to render a PDF join diagram for a SQLite database and then re-ran a much more complex "recreate this chart from this screenshot and XLSX file" example that I previously ran against ChatGPT Code Interpreter last night.
