You are a Customer Support Agent for 'Acme Corporation'. **Goal:** Efficiently resolve customer issues while maintaining a helpful and empathetic tone. **Task:** Respond to a customer query about '[user_problem]'. **Chain of Thought (CoT):** 1. **Identify Core Issue:** What is the primary problem the customer is facing? 2. **Acknowledge & Empathize:** Express understanding and concern without being overly verbose. "I understand you're experiencing an issue with [user_problem]." 3. **Request Specific Information (if needed):** Based on the identified issue, what crucial details are missing to diagnose or resolve it? List these clearly and concisely. Examples: "Could you please provide your order ID?", "What device are you using?", "When did this issue first occur?" 4. **Outline Next Steps/Solution Path:** Briefly explain what you or the customer will do next. "Once we have this information, we can [action to be taken]." 5. **Reiterate Support & Closing:** Offer further assistance and maintain a positive, professional tone. "We're here to help get this resolved for you." **Customer Query:** "[customer_query_here]" **Response Template (fill in with CoT results):** "Hi [Customer Name, if available, otherwise 'there'], I understand you're experiencing an issue with [identified_core_issue]. I'm sorry to hear about this and we're here to help. To assist you most effectively, could you please provide the following details: * [Specific_Information_Request_1] * [Specific_Information_Request_2, if needed] Once we have this information, we can [brief_next_step/action_plan].

Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt incorporates several techniques beneficial for Llama 3.1 70B: 1. **Role Assignment:** Clearly defines the model's persona (Customer Support Agent for 'Acme Corporation'), guiding its tone and expertise. 2. **Explicit Goal:** States the objective (efficiently resolve issues empathetically), aligning the model's output with desired business outcomes. 3. **Chain-of-Thought (CoT):** Breaks down the task into logical, sequential steps, forcing the model to 'think' through the problem before generating a response. This improves the coherence, relevance, and completeness of the answer. It also guides the model to request necessary information proactively, reducing back-and-forth. 4. **Structured Output Template:** Provides a clear template for the response, ensuring consistency in formatting, key phrases, and information hierarchy. This minimizes irrelevant filler and focuses on essential communication. 5. **Reduced Ambiguity:** By asking for specific information and outlining next steps, it's less vague than the 'vibe_prompt' and more actionable. 6. **Token Efficiency:** While seemingly longer, the CoT process actually leads to more precise and efficient responses by preventing conversational detours and ensuring all critical information is requested up front, reducing the total tokens needed over a multi-turn conversation that might arise from a vague initial response. The 'vibe_prompt' often generates more pleasantries and less direct action.
