How do you debug agent workflows when there is no clear pass or fail?

film-chick · reddit · 2026-07-28

The poster asks how people debug and improve agentic workflows when the process is non-deterministic and there is no clean pass/fail signal. They say observability alone has not been enough, because it mostly produces event logs without telling them what to fix.

The thread frames the problem as one of evaluation: what metrics matter, how to know whether an agent is actually improving, and whether traditional programming habits still apply. The poster wants concrete guidance on interpreting observability data and deciding what to optimize.
