Agent Oversight

Every screen exists because a system needed something from a person. As AI gets better at working things out on its own, most of those screens go away. The ones left are where a person needs something back: to see what it did, to trust it, to stop it.
I mocked one up for a travel agent. It only asks for my call when it's spending money or when two of my own rules disagree. Everything else is a log with an undo button.

Chat EQ

A mixing board for how AI talks to you. Seven sliders — length, method, stance, register, structure, creativity, model size — each running between two honest extremes, from one-liner to dissertation, brutal to supportive, literal to unhinged. Set them by feel, or start from a preset like Rubber Duck or Drill Sergeant, and Chat EQ compiles your settings into a plain-language directive you can paste into any chat.
