Agent Engineering Lab earn the complexity

Build agents that survive contact with reality.

Earn the complexity

Start → Read the book See the evidence
An engraved emblem of accountable autonomy: a thinking core on an orbital loop, a verifier balance on one side, and a sealed, padlocked gate on the other

The Creed

  1. 01 Most agents are workflows in costume.
  2. 02 Reliability lives in the harness, the loop, and the gate, not the model.
  3. 03 Earn the complexity.
  4. 04 Evidence over hype.
