Traces aren't enough for AI agent observability, says team building outcome verification

Ok-Machine7983 · reddit · 2026-11-06

A developer building agent monitoring infrastructure argues that traditional traces — LLM calls, tool calls, inputs/outputs — don't tell you whether an agent actually achieved the intended outcome: did the calendar event really get created, did the CRM record truly save?

Their approach: a proxy-based system capturing agent interactions, coupled with external systems to verify what actually happened. The post ends with questions for production users on how they verify completed actions, and which failure modes are hardest to detect.
