1Support Triage Assistant Keeps Escalating Simple Refunds
You run a customer-support assistant built on Claude with three tools: lookup order(order id) , issue refund(order id, amount) , and search policy(query) . In production over 5,000 conversations, 38% of refund requests get escalated to a human, but the human team finds that 90% of those escalations were straightforward refunds under 50 that policy allows the assistant to handle directly.

A coding assistant's system prompt has grown over 14 months from 600 to 9,000 tokens as teams appended rules for edge cases: formatting, security caveats, tone, framework-specific guidance, and 40 few-shot examples. Users now report the assistant ignores formatting rules it used to follow, and security caveats appear inconsistently.
