When your AI agent gives a wrong answer, there's always a specific, fixable reason. This guide walks you through the diagnostic process to find the root cause — and the exact fix for each scenario.

Root cause 1 — The information isn't in the knowledge base

Symptom: Agent says "I don't have information on that" or gives a vague, hedging answer.

Fix:

  1. Go to your Knowledge Base tab
  2. Search for the topic the agent failed on
  3. If nothing relevant appears — that's your answer. Add the missing content as a manual Q&A entry.

Root cause 2 — The information is outdated or incorrect

Symptom: Agent gives a specific but wrong answer (old price, discontinued service, changed policy).

Fix:

  1. Search the knowledge base for the topic
  2. Find the outdated entry
  3. Delete it — don't disable it, delete it. Disabled entries can still be retrieved.
  4. Add a new entry with the correct information
  5. Re-test the question to confirm the fix

Root cause 3 — Conflicting information in the KB

Symptom: Agent gives inconsistent answers to the same question — sometimes right, sometimes wrong.

Fix: Search the knowledge base for the topic and look for multiple entries that say different things. Delete all but one — the most current, most accurate version. Inconsistency in the KB is one of the hardest problems to diagnose because it only shows up sporadically.

Root cause 4 — System prompt is too loose

Symptom: Agent goes off-topic, invents information, or gives answers outside its intended scope.

Fix: Add explicit scope limits to your system prompt:

Only answer questions about [business name] and its services.
If asked about anything outside this scope, say: 
"That's outside what I can help with — but for [topic], 
you can reach us at [email]."
Never speculate or guess beyond what you know.

Root cause 5 — Temperature too high

Symptom: Answers are varied, creative, sometimes off-base. The agent seems to be "making things up" occasionally.

Fix: Lower the temperature setting to 0.3–0.4 in your agent settings. This anchors responses more tightly to the knowledge base content.
