Founder and engineer, Terse.
Luz Wang builds Terse — an on-device optimizer for AI coding agents that compresses prompts before they reach the API, monitors eight agents live, and caps runaway spend with a budget circuit breaker.
The work on this site comes out of building that: the guides here are about where tokens actually go inside an agent loop, which of them are avoidable, and what the compression is worth once context carries forward turn after turn.
