Make your own event-sourced agent harness using stream processors — Jonas Templestein, Iterate

Jonas Templestein , Iterate

Overview

This talk introduces a novel approach to building agent harnesses using an event-sourced architecture powered by stream processors. The core thesis is that by treating all agent interactions and state changes as events in a log, debugging becomes significantly easier, and extensibility is greatly enhanced. This event-driven model aims to simplify experimentation with different agent configurations and facilitate composable agent systems.

Notable quotes

*The way I would like to do it is I would like to do it purely event sourced. And I say here aka debuggable.*
*The moment an agent exists, it should have a URL.*
*The idea is to create a system in which it is trivially easy with three, four lines of code to add one of those capabilities to it.*
