Your Agent Called a Tool That No Longer Exists

Описание: When an LLM agent calls a tool that no longer exists, it often looks like model hallucination. The real culprit is usually silent schema drift: the model is operating on stale tool definitions while the backend API has changed.

Observability Labs recreates production failures and shows the telemetry that catches them: OpenTelemetry, distributed systems, platform engineering, and AI agent debugging.

In this video, we explore how to bridge this tool-call gap using OpenTelemetry's semantic conventions for generative AI.

Learn how to intercept tool calls, validate payloads against live JSON schemas, and emit structured telemetry to pinpoint exactly where your agentic pipelines are breaking.
