Why auto-saving LLM hypotheses into memory is a terrible idea: lessons from an incident triage agent
afsana08 · reddit · 2026-09-30
The author's team open-sourced Incident Memory Agent (Vectorize Hindsight + Groq) and shared hard-won SRE agent lessons: auto-saving LLM hypotheses poisons memory — weeks later the agent recalls its own hallucination as verified team truth, so only engineer-validated resolutions are retained. Storing failed approaches (e.g., pod restarts that re-saturated connection pools in 90s) explicitly warns future responders. Latency is split into fast semantic recall (1–2s) for live triage vs. deep reflection (10s) for postmortems. Known limits: manual intake, no PagerDuty webhook, no autonomous remediation, no memory decay.
