Kai
An agent system I designed, built, and operate on a headless Mac Mini M4. Its face is @kAI, the concierge I message on Discord: scheduled jobs, a memory vault in markdown and git, and delegation rules that keep me in the loop.
what it does/
It runs my day. I message @kAI on Discord from my phone, it files whatever I throw at it, runs scheduled jobs that propose work and wait, and hands build work to a flat-rate coding agent. Nothing lands without my approval.
how it works/
The parts are deliberately boring: Discord as the doorbell, markdown and git as the memory, cron for scheduling. The plan had four personas; what runs is leaner. One concierge routes everything, a builder does the heavy work, and the curator got folded into a single channel once a separate profile stopped earning its keep. The engineering is in the delegation rules: agents propose before they act, commits go through a human gate, self-rewrites are staged for review, and anything that installs software passes a security gate.
operating it/
Live since July 3, 2026, operated daily. The first eleven days produced three distinct provider-auth failures, each with a different symptom and a different fix. Metered API spend measured at about $9 a day got re-architected down to near zero.
scope/
It runs my life, not a business. One user, me, and that is the point: when it breaks, I am the one who gets paged.
