## AI overview

Harness describes AgentTrace, an internal framework for observing, evaluating, and governing AI agents in production. It connects production monitoring with evaluation, allows failures to become regression test cases, and includes open-source harness-sdk and harness-evals layers under Apache 2.0 that work with any OpenTelemetry backend.
