Add skills to your agent, swap the model, tweak a tool description. How do you know you didn't break what already worked?
Managed Deep Agents ships with @harborframework.
Evals run in a fresh container every time, tracked in LangSmith.
What you need to know in 9 minutes:
eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
