AI agents need pre-call guards for control, not just post-hoc telemetry

Observability for AI agents, particularly regarding cost and control, is a critical but often overlooked aspect of their development. While tools like GitHub Copilot now offer telemetry features such as session streaming and OpenTelemetry exports, these primarily provide evidence of what happened after the fact. True control, however, involves preventing undesirable actions before they occur, such as excessive retries or prompt loops that can lead to wasted resources. Implementing pre-call guards that assess factors like budget, step limits, and potential infinite loops can significantly enhance agent reliability and cost-efficiency, complementing existing telemetry by providing actionable insights into why certain actions were blocked.

    Agent Telemetry Is Not Agent Control

    <p>GitHub's Copilot updates added session streaming, cost tracking, OpenTelemetry exports. Useful. But here's the thing: seeing what went wrong and stopping it before it happens are not the same layer.<br /> You can log that an agent retried 14 times. You can't prevent call 15 fr…
