Series

Viable Agents

What keeps agentic software development viable once implementation gets cheap? Each part takes one practical problem with coding agents, reads it through cybernetics, and ends with what to build. The series is written alongside regulator, and the Viable Agents course builds the same ideas into a harness.

In reading order. 2 parts so far; new parts are added as they're published.

The metasystem didn't get an amplifier

Agents multiplied what a codebase can become without multiplying anyone's ability to notice. Ashby's law, Beer's Viable System Model, and drift as a variety imbalance.

Prompts advise, types describe, gates enforce

A rule written in a prompt holds until the model has a good enough reason not to follow it. The mechanism hierarchy, and why every gate must say what it fails to catch.
