Braintrust launches native Flue integration

Agent tracing is the new standard debugger for autonomous AI. Standard APM tools are completely blind to recursive tool loops and state shifts, making native integrations like Braintrust and Flue crucial for production-grade agent development. Multi-turn autonomy requires hierarchical tracing to map out how main goals break down into subgoals and tool calls. Auto-instrumentation via Braintrust's import hooks minimizes developer friction, encouraging better observability habits from day one. Ultimately, having a specialized tracing harness is key to moving agents from prototype to predictable, production-ready software.
