Maintain Consistent AI Outputs Using a Contract Prompt
Job to be done: Maintain consistent AI content generation outputs despite model updates
🇳🇬 Ways to use this in Nigeria
Ideas to get you started, adapt to your situation.
- Entrepreneur
Create consistent Instagram captions for your product launch by defining format, tone, and mandatory mentions in a contract prompt.
- Small business
Generate identical WhatsApp product descriptions daily, ensuring price and key features are always included using a contract prompt.
- Student
Produce consistent summaries of lecture notes, always including key dates and definitions, by using a contract prompt for the AI.
What you’ll get
You’ll get a method to ensure your AI-generated content stays consistent in format, tone, and content, even when the AI model itself updates. This approach works by giving the AI a very specific ‘contract’ to follow, which limits how much it can change its output when its internal behavior shifts.
Tools you need
- ChatGPT (freemium): A popular AI chat assistant for generating text.
- Claude (freemium): Another AI chat assistant known for its long context window and writing abilities.
- Gemini (freemium): Google’s AI chat assistant, integrated with Google services.
Steps
-
Open your AI chat tool: Go to your preferred AI chat website (like ChatGPT, Claude, or Gemini) on your phone or computer.
- You should see the chat interface ready for you to type a message.
-
Copy the contract prompt: Copy the entire prompt template below.
You are producing [type of output]. Follow this contract exactly, every time: FORMAT: [exact structure: sections, length, bullets vs prose] MUST INCLUDE: [non-negotiable elements] MUST NOT: [things it keeps drifting into: filler, extra headers, hype words] TONE: [three concrete adjectives + one example sentence in that voice] IF UNSURE: ask one clarifying question instead of guessing. Before you output, silently check your draft against every line above. If it fails any line, fix it before responding. Do not explain the check.- The prompt text should be copied to your clipboard.
-
Fill in the blanks for your task: Paste the copied prompt into a text editor (like your phone’s notes app or a simple word processor) or directly into the AI chat window. Replace each bracketed placeholder
[like this]with specific instructions for your content. Here are some examples:[type of output]: e.g., “a short social media post”, “a product description”, “a blog post outline”.[exact structure: sections, length, bullets vs prose]: e.g., “one paragraph, 100 words max, no bullet points”, “three sections with H2 headings, each 2-3 sentences, using bullet points for key features”, “a list of 5 bullet points, each 10 words or less”.[non-negotiable elements]: e.g., “always mention the product name ‘SuperClean Detergent’”, “include a call to action to ‘Visit our website’”, “use the hashtag #LocalBusiness”.[things it keeps drifting into: filler, extra headers, hype words]: e.g., “avoid generic phrases like ‘unlock your potential’”, “do not add extra headings beyond what’s specified in FORMAT”, “no overly enthusiastic language or exclamation marks”.[three concrete adjectives + one example sentence in that voice]: e.g., “Informative, friendly, concise. Example: ‘Learn how our new app simplifies your daily tasks.’”, “Professional, direct, encouraging. Example: ‘We invite you to explore the benefits of our service.’”- You should have a complete, customized prompt with no brackets left.
-
Use your customized contract prompt: Copy your filled-in prompt and paste it into your AI chat tool. Then, provide the specific content or topic you want the AI to work on.
- The AI should generate content that strictly follows all the rules you set in your contract prompt. If it deviates, you can refine the specific line in your contract that it failed to follow.
Original source
This workflow comes from a Reddit user named /u/Ok-Independent3290, who shared this technique on the platform to help others maintain consistent AI outputs despite quiet model updates.
Notes & variations
Common Pitfall: The biggest mistake is being too vague in your contract. For example, ‘FORMAT: short’ is not as effective as ‘FORMAT: one paragraph, 80-100 words, no bullet points’. The more specific you are, the less room the AI has to ‘drift’. If the AI output isn’t right, don’t just tell the AI ‘make it shorter’; instead, go back and tighten the specific line in your contract that it failed to follow.
Tip for Better Results: Save a separate, fully customized contract prompt for each recurring content task you have (e.g., one for social media posts, one for product descriptions). This way, you can quickly reuse the exact contract and only make minor adjustments as needed.
Free-tier viability: All the recommended tools (ChatGPT, Claude, Gemini) offer robust free tiers that are perfectly capable of handling this workflow. You won’t need to pay to get good results.
