Why this matters
What breaks when you run Claude Opus 4.5 raw
But retrieval, grounding and workflow orchestration matter more than raw intelligence in production customer support.
Hallucinated answers. Claude Opus 4.5 might confidently give wrong details about your product or policies.
Stale information. It can't update answers when your policies or product change.
No account context. It has no access to the customer's order or account details.
Inconsistent retrieval. Answers vary even for the same question asked twice.
Policy drift. Over long chats, it may start giving answers that break your brand voice or policies.
No human handoff. It can't escalate complex cases to your support team.
