Life-Harness
Sometimes the best way to improve an agent is not to change the model, but to change the interface it works through.
Signal summary
Life-Harness is a strong signal for deterministic interface design. It points to the importance of environment contracts, action realisation, trajectory regulation, and procedural playbooks around a frozen model. The agent's behaviour improves because the world it acts through becomes clearer and more structured.
Why it matters
Agents often fail at the boundary between intention and action. They claim something happened when it did not, misunderstand available actions, or drift through poorly specified environments. Harnesses reduce this ambiguity by making the interface explicit.
LGI reading
This is central to LGI's operating model. The serious work is not only choosing a model; it is designing the harness: what the agent can see, what it can do, what must be verified, what gets logged, and when a human must approve.
Use this if you are thinking about
tool use, deterministic interfaces, agent reliability, command surfaces, environment feedback, and safe operational deployment.
