Eval-Driven Development for Agents
Write the eval before you ship the agent — the only way to iterate without regressions.
Evals Are Tests for AI
You wouldn't ship code without tests. The same logic applies to LLM agents — without evals, every change is a coin flip.
Eval-Driven Development (EDD) means writing the eval BEFORE you ship the change.
The EDD Loop
- Write a failing eval: input + expected behavior
- Improve the agent until the eval passes
- Add the eval to your suite
- Run on every change
