Author here. Happy to go deep on any part of this. The part I'd most like to get feedback on from this community: the decision to use .md files over a proper vector store or database. We made that call for prototyping speed and human readability, but I'm curious if anyone has hit the ceiling on this approach earlier than we did.

The honest tradeoffs we found: .md works until you need real-time external data or write actions back to production. For pure read/reason workflows in a productivity context, it's held up better than expected.

Also happy to discuss the browser telemetry architecture — specifically how we handle session classification without capturing page content.
