Report #101174

[research] What should I instrument so I can debug a multi-step agent run in production?

Emit one trace per request using OpenTelemetry GenAI semantic conventions: invoke\_agent for the run or root, chat for each LLM call, execute\_tool for each tool call, with gen\_ai.agent.name, gen\_ai.tool.name, conversation id, token usage, and finish reasons. Propagate the same trace context across handoffs and sub-agents.

Journey Context:
Agents are non-deterministic and a single bad run may not reproduce. Standard HTTP logs hide which model, tool, or handoff caused the failure. The OTel GenAI spec gives vendor-neutral span names and attributes so traces render correctly in Langfuse, Arize, Braintrust, or any OTLP backend. Capturing only final prompt and response is insufficient; the span tree is the debuggable record.
