How a small team operates every layer of a production voice-AI platform: fleets of coding agents in up to 85 parallel worktrees, one shared authority loop, and a guard stack that permission-blocks dangerous actions.
Keep readingPerimeter security assumes something upstream already checked the caller. That assumption is how a lot of breaches happen. How we think about authenticating inside every function — and the test that proves it.

A plain-language explanation of IntuneLabs, Simcheong, the parts behind a voice exchange, and the difference between product code and public availability.

Five optional voice prompts built around a pause, tea or music, reflection, a chosen call, and the close of the day.
