After months of tweaking, I'm finally happy with my agents' setup (and runtime). It fetches information automatically, on a schedule, or reacts to events. I can send a voice note, interact via text messages, or use voice mode in Codex. It's easy to debug.
Codex is almost there, but unfortunately not quite there, so a lot of development was involved.
But has made a lot of my mental load disappear, and this is priceless; I totally feel like I'm living in the future now.
