Report #65377

[research] Agent observability is fragmented with custom logging that cannot be correlated across asynchronous tool calls

Instrument agents using OpenTelemetry \(OTel\) traces and spans. Map each agent iteration to a Span and each tool call to a child Span, propagating trace context through the agent's internal state to link asynchronous callbacks.

Journey Context:
Standard logging breaks down when agents loop or branch asynchronously. You lose the causal link between a tool output and the LLM's subsequent reasoning. OTel provides the standard baggage and trace\_id propagation needed to stitch a complete DAG of the agent's execution, enabling filtering by trace\_id in backends like Grafana or Datadog to see the exact failure path.
