Former Google Engineer Explains How AI Agent Loops, Harness, and Evals Work in 20 Minutes.
A Google expert reveals the mechanisms behind improving AI agents through loops, memory, and evaluations.
The logic is simple: trace each run → pass it through an LLM evaluator → identify failures → fix them → roll out a new version.
This is how agents gradually improve.
- Agent loops: The core mechanism that allows agents to learn from their mistakes.
- Memory: Stores information about previous runs, helping to avoid repeating errors.
- Harness: A tool for testing and integrating agents into various environments.
- Evals: Performance assessment of agents to identify their weaknesses.
