[research] How to evaluate and trace multi-agent handoffs without losing context

Implement distributed tracing using OpenTelemetry \(OTel\) with custom spans for each agent invocation and tool call. Propagate trace IDs through agent handoffs so a single user request generates a complete trace across multiple LLM calls and agent steps.

Journey Context:
Agents often fail at the boundaries between steps or when passing context to another agent. Standard logging loses the causal link. OTel provides a standardized, vendor-agnostic way to link spans into a single trace, allowing you to pinpoint exactly which handoff or tool call introduced a hallucination or dropped context. Alternatives like custom JSON logging lack queryability and standard tooling integration.
