The "Vibe" Prompt

"Write an email to a colleague, Alex, about the project deadline. Make it friendly but firm."
Low specificity, inconsistent output

Optimized Version

STABLE
You are Llama 3.1 405B, an advanced AI designed for effective and nuanced communication. Task: Draft a professional email. Recipient: Alex (colleague) Subject: Project Alpha Deadline Reminder Tone: Friendly but firm. Maintain a collaborative yet results-oriented approach. Key Information to Convey: 1. Acknowledge current progress (if any, assume 'good, but nearing deadline'). 2. Reiterate the upcoming deadline (assume 'End of Business, Friday, October 27th'). 3. Emphasize the importance of meeting this deadline for downstream tasks/project success. 4. Offer support or clarity on any blockers Alex might be facing. 5. Request confirmation of understanding or an update on their progress. Constraint: Keep the email to under 150 words. Do not use overly informal language. Chain of Thought: 1. **Understand Goal:** Write a friendly but firm email to Alex about a project deadline. 2. **Identify Recipient & Subject:** Alex, 'Project Alpha Deadline Reminder'. This is clear and professional. 3. **Determine Tone:** Friendly opening, firm on deadline, collaborative on support. 4. **Extract Key Information:** Need to include progress acknowledgment, deadline, importance, offer help, and request update/confirmation. 5. **Draft Opening:** Start with a friendly greeting and a brief positive comment, then transition to the deadline. 6. **State Deadline Clearly:** Use the specific date and time established. 7. **Explain Importance:** Briefly link the deadline to project success/next steps. 8. **Offer Support:** Proactively offer assistance for potential issues. 9. **Call to Action:** Ask for an update or confirmation. 10. **Closing:** Professional and collaborative. 11. **Review Constraints:** Check word count (under 150), formality. Ensure all key points are covered in the specified tone.
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt provides Llama 3.1 405B with a highly structured and detailed set of instructions, including explicit persona, task breakdown, recipient and subject details, desired tone, key information to include, and crucial constraints (word count, formality). The 'Chain of Thought' section guides the model through a logical reasoning process, breaking down the task into manageable steps and ensuring all requirements are addressed systematically. This reduces ambiguity, minimizes the need for inference, and leads to a more precise, reliable, and compliant output. The model doesn't have to 'guess' what 'friendly but firm' implies or which details are essential; it's all explicitly laid out.
