Report #4625

[research] Agentic workflows make it impossible to attribute token costs and latency to specific features or user actions

Tag every LLM span in the trace with business-logic metadata \(e.g., feature, user\_tier, intent\) at the root span, and propagate this context to all child agent and tool spans.

Journey Context:
Standard LLM observability tracks total tokens per model, but in an agentic system, a single user request might spawn a planner agent, a coder agent, and a reviewer agent. Without business-logic tags on the traces, you cannot answer 'which feature is driving up costs?'. By injecting this metadata into the trace root and propagating it, you can aggregate telemetry dashboards by feature/intent to identify exactly where to optimize.
