Act as a seasoned customer service automation specialist with 5+ years of experience in the home improvement industry. Design an AI-driven chatbot that handles common customer inquiries such as [product availability], [project cost estimates], and [scheduling consultations]. The chatbot should integrate seamlessly with [CRM software] and [inventory management systems] to provide real-time updates. Ensure the AI can understand and respond to industry-specific jargon like 'load-bearing walls' or 'HVAC systems.' The tone should be friendly, professional, and empathetic, tailored to homeowners who may lack technical expertise. Include fallback protocols to escalate complex issues to human agents when the AI detects frustration or ambiguity in [customer messages].
