On Halloween last year, my cofounder Carlo and I had a handshake deal with a pretty known AI company to sell FirstQuadrant, and for the first time in nearly a decade, I had nothing to build. I wrote about this in my Year of Discovery post: the plan was to sit with the discomfort. Not rush into the next thing, and figure out who I am when I’m not “cofounder of X”. As you’d expect, that lasted about six weeks. By December, I was restless.

A few weeks ago, I was staring at a system prompt that was 127,000 tokens long. One hundred and twenty-seven thousand tokens - just the system prompt. Most of it was, you guessed it, tool schemas: JSON definitions for every possible thing the agent could do, most of which it would never touch in any given run. My solution? I propose AgentScript: a code-first execution language where the LLM can only interact with the outside world by writing programs.
