General Guidelines: Translating Intentions to Prompts\n\n###\nThe Core Principle: Information Density\n\nEvery word in your prompt must **pull its weight**. AI models don't read \"terms and conditions\"—they process tokens efficiently.\n\n| Before (Bloated) |\nAfter (Concise) |\nWord Reduction |\n| \"Can you please give me a really detailed, comprehensive, and extensive explanation of why some prompts might not work as well as others in AI models, and maybe share examples?\" |\n\"Why do long prompts lower model accuracy? Explain with examples.\" |\n70% |\n| \"You are a world-class chef specializing in Italian cuisine. Please imagine that you are teaching a class on easy pasta recipes. Provide a detailed explanation for each step...\" |\n\"You are a chef teaching beginners about pasta. Share an easy recipe with ingredients, cooking times, and dietary alternatives. Use a fun tone.\" |\n~85% |\n\n###\nThe \"Burger Prompt\" Framework\n\nThink of a prompt like a burger—skip the lettuce (unnecessary fluff):\n\n**Example:**\n\n###\nGolden Rules for Intent Translation\n\n-\n**Speak with Purpose**: Don't waffle. Be direct\n-\n**Condense Rules**: Instead of \"Make sure the tone is casual but not too casual. Also, ensure there aren't any assumptions. By the way, output should be JSON,\" use \"Respond in casual tone, no assumptions, JSON format\"\n-\n**Use Delimiters**: Separate sections with `###`\n\n, `\"\"\"`\n\n, or `---`\n\nto clarify instruction vs. input data [linkedin](https://www.linkedin.com/pulse/unlocking-ai-productivity-prompt-engineering-playbook-luke-mclaughlin-viotf)\n-\n**Indicate Output Format Explicitly**: Say \"in one paragraph\" or \"no more than 100 words\" for length control [linkedin](https://www.linkedin.com/pulse/unlocking-ai-productivity-prompt-engineering-playbook-luke-mclaughlin-viotf)\n\n##\n2.
