Tracing

import { LangfuseClient } from '@anvia/langfuse'

const langfuse = new LangfuseClient({
  serviceName: 'support-api',
  environment: 'production',
})
const tracing = langfuse.observer({
  captureMode: 'safe',
})

Attach tracing under a named key in the agent's observability.observers record (for example observers: { tracing }); primaryTrace references one of those keys. Runs become Langfuse agent observations with generation, tool, guardrail, event, usage, trace, and error detail.

Use captureMode: 'full' only when model and tool payloads may be exported. Call langfuse.flush() for short-lived work and langfuse.close() during final cleanup.
