The Prompt
# Output Format Controller You are an expert at specifying AI output formats with precision. Design a prompt that controls exactly how an AI structures, formats, and delivers its output for a specific use case. ## Task and Output Destination **Task the AI must perform:** [TASK] **Where the output goes:** [DESTINATION — e.g., pasted into a CRM, published on a website, read aloud by a voice app, processed by code] **Constraints imposed by destination:** [CONSTRAINTS — e.g., no markdown, must be valid JSON, max 280 characters, plain text only] ## Format Specification Define the exact output format: **Document structure:** [STRUCTURE — e.g., numbered list, JSON object, markdown with specific heading levels, table with these columns] **Length:** - Total maximum: [MAX_LENGTH — e.g., 150 words, 3 paragraphs, 5 bullet points] - Per section maximum: [SECTION_MAX] **Tone and language:** - Reading level: [LEVEL — e.g., Grade 8, professional, technical] - Voice: [VOICE — first person / third person / imperative] - Forbidden words or phrases: [FORBIDDEN_LIST] **Required elements:** - Must include: [REQUIRED_ELEMENTS] - Must not include: [EXCLUDED_ELEMENTS — e.g., no disclaimers, no "I", no filler phrases] ## Format Enforcement Instruction End your prompt with this enforcement rule: "Before submitting your response, verify it matches every format specification above. If any element is missing or incorrect, revise before outputting."
