AgentSight and LangSmith

LangSmith records instrumented application operations as traces and runs. AgentSight observes the local agent and child-process boundary, including components that do not emit LangSmith telemetry.

Use LangSmith for application traces and evaluation workflows.

Use AgentSight to inspect execution outside application spans.

Correlate both for a fuller run narrative.

Runs are not operating-system processes

A LangSmith run is an instrumented unit of application work. A process, command, file effect, or network connection is a different kind of evidence. AgentSight focuses on those system-level relationships.

Keep semantic and execution views connected

Use LangSmith where its integrations capture the agent graph and application context. Add AgentSight when investigation requires the actual shell commands, process tree, local files, or closed-source CLI behavior.
