Agent Observability

Instrumentation that reconstructs an agent's full execution path — tool calls, memory reads and writes, reasoning steps, and handoffs between agents — rather than just input, output, latency, and cost the way standard LLM-call observability does.

Standard LLM observability captures a single model call. Agent observability has to reconstruct a full execution path across multiple tool calls and handoffs — a different problem, not a bigger version of the same one.
