Report #76499

[research] Observability dashboards only show LLM API latency, missing the agent's cognitive reasoning time and decision steps

Structure traces around Agentic Spans \(Plan, Action, Observation\) rather than just API Spans \(Completion request/response\). Add semantic attributes like agent.thought to plan spans.

Journey Context:
Wrapping an LLM call in an OTEL span is basic. For agents, the API call is just one part of the cognitive loop. The time spent parsing the output, deciding the next step, or handling retries is invisible if you only trace the API. You need a semantic convention for the agent's internal state machine to see where time is actually spent and where bottlenecks occur.
