Agent failures where every dashboard was green: Reddit collects real post-mortem war stories
Sensitive-Parsnip-12 · reddit · 2026-09-06
A developer asks for real cases where an LLM/agent run showed zero technical failure — no exceptions, tool calls returned 200s, checks passed, traces looked clean — yet the outcome was still wrong. They explicitly want ugly debugging stories beyond generic "LLMs hallucinate": what happened, what was checked first, what tipped the investigator off, and what telemetry should have been captured. A valuable discussion thread for agent eval and observability engineering.
