Act as a Senior Customer Experience Engineer with 5+ years of expertise in AI-driven support systems. Design a prompt for an AI-powered escalation system that identifies, prioritizes, and routes high-priority customer inquiries in an [ECOMMERCE PLATFORM] based on [ISSUE SEVERITY] and [CUSTOMER TIER]. The system should analyze chat logs, purchase history, and sentiment in real-time to escalate cases requiring human intervention. Include logic to auto-suggest resolutions for common issues like [RETURNS], [DELAYED SHIPMENTS], or [PAYMENT FAILURES]. Ensure the prompt specifies response time targets, fallback protocols for AI uncertainty, and integration with [CRM TOOL] for seamless handoffs. Provide examples of escalation triggers and de-escalation criteria.
