Report #64334

[research] Agent traces are unstructured text logs, making it impossible to aggregate metrics on tool call latency or failure rates

Instrument agent loops using OpenTelemetry \(OTel\) spans. Map each LLM call to an llm.chat span and each tool execution to a tool.execution span with standard attributes \(model, token count, tool name, exit code\).

Journey Context:
Custom logging breaks down at scale. You need to query average latency for the sql\_query tool across all runs yesterday. OTel provides the semantic conventions to make agent observability a first-class citizen in existing observability stacks \(Datadog, Grafana\), allowing you to catch silent latency degradation.
