API Reference
TraceMeta
Defined in: observability/tracer.types.ts:28
Run-level configuration captured alongside the timeline — the context you
need to reproduce or compare a run. Filled in from whatever taps are wired:
sessionId from the agent's agent_start, system/tools from the model
request (via observe), and model/params/system from a provider's
onRequest tap (e.g. OpenAICompatibleModel).
