icip-cas/pptagent — reverse-engineered prompt

Build me a local AI PowerPoint maker based on this repo. I want something I can run on Mac or Linux, and on Windows through WSL, that lets me describe a presentation in plain English and get back a polished PPTX file. It should also accept supporting files like PDFs, spreadsheets, and other attachments so it can build a better deck from real material, not just a prompt.

Please make the CLI flow the main path, with a simple first run setup that helps create the needed config files and explains what is missing. If there is already a web UI in the project, wire that up too so I can use either option. I want support for a fully local or offline setup when possible, but also optional upgrades for better web research, PDF parsing, and image creation if I add API keys later.

Please make it easy to start with a minimal test presentation, then generate a fuller deck from files. If anything is unclear, check the current docs online and finish the setup end to end.
