@respan/instrumentation-braintrust

Respan instrumentation for Braintrust TypeScript tracing.

import { Respan } from "@respan/respan";
import { BraintrustInstrumentor } from "@respan/instrumentation-braintrust";

const respan = new Respan({
  instrumentations: [new BraintrustInstrumentor()],
});

await respan.initialize();

The plugin installs a Braintrust background logger bridge and translates Braintrust project log and span rows into Respan OTEL spans. It preserves Braintrust metadata, metrics, scores, tags, merge updates, parent span relationships, and error rows while emitting Respan canonical GenAI, LLM, and entity attributes.
