β οΈ Prompt Drift Detected - Escalation Rate Spike
Issue: Agent began hallucinating appointment times on Nov 14, 2025 at 2:47 AM EST. 12 calls escalated to human operators in 3-hour window (normal: 2-3/day).
Root Cause: Prompt didn't explicitly handle timezone conversion when customer location differed from business hours reference.
Chris's Fix: Added explicit instruction layer: "Business hours are 9AM-5PM Eastern Time. Always convert customer's stated availability to ET before confirming. If customer timezone unclear, ask explicitly before booking." Result: Escalation rate returned to baseline within 4 hours.
