KItsu-sama/second_brain ? reverse-engineered prompt

Build me a simple Python CLI app called Second Brain that lets me save things I come across, like plain notes, web links, YouTube videos, GitHub repos, and Facebook reels, into one inbox.

I want to be able to add one item or a whole text file of items, then process the saved stuff later so it gets summarized, tagged, and given a rough estimate of how long it would take to review. If there’s no AI key set up, it should still work with a basic fallback so the whole flow runs end to end.

Please include commands to add items, process pending items, list what I’ve saved, search by keyword, recommend the best things to spend about 20 minutes on, mark something as consumed, and export cleaned chunks for future RAG use. Use SQLite for storage, keep the design simple, and make it easy to add new sources later. If you need to look up current docs online, go ahead.
