Prompt Templates for Business: Building Reusable, Maintainable Prompts
Business prompts get reused hundreds of times, so they deserve templates. Here is how I build maintainable prompt templates. Business prompts have a property that creative prompts do not: they get reused. A prompt that drafts a customer email, summarizes a meeting, or extracts action items runs dozens or hundreds of times, which means small improvements compound. Treating business prompts as templates, with slots that get filled at runtime, is the shift that turns prompting from a one-off craft into a maintainable system. This guide covers the template patterns I use for repeatable business tasks. The Slot-Based Template Pattern A prompt template is a string with placeholders that get filled with variable values before the prompt is sent to the model. The fixed text defines the task and format. The slots carry the variable data. The separation is what makes the template reusable, because the fixed text never changes and the slots carry whatever the current task needs. // Customer email reply template You are a customer support agent. Draft a reply to the customer message below. Customer name: {{customer_name}} Customer message: {{customer_message}} Product: {{product_name}} Reply rules: - Acknowledge the specific issue they raised. - Offer one concrete next step. - Keep the reply under 120 words. - Do not promise refunds or credits. The double-brace slots are filled at runtime with values from the database or the current request.
