Customer Service AI Agent System Prompt Generator

Turn a few lines about your business into structured instructions for a customer service AI agent — business context, role, style and guardrails — ready to paste into its setup.

Every AI support agent starts with a page of instructions, and most of those pages are written in a hurry: "You are a helpful assistant for Northwind. Be friendly." Then the agent quotes an old price, promises a refund it cannot give, and argues with someone who wanted a person. The instructions were not wrong; they were empty. What the agent needed was the twenty facts and the five rules the support lead already knows and never wrote down.

This tool is the instruction drafter from WireDesk's onboarding, opened up. Write a few lines about the business — what you sell, hours, what to never say, when to escalate — and it drafts a structured instruction set in four sections: Business Context, Role, Style and Guardrails. It runs on the same model that answers WireDesk customers, and the output pastes straight into WireDesk's agent setup or any other system that takes a system prompt. It is a draft: read every line, because it is what the agent will do. The model reads your notes once; nothing is stored beyond a short cache.

Example: instructions for a B2B accounting software support agent

Business Context
Northwind makes accounting software for small firms — bookkeepers, accountants and owner-managed businesses. Plans are Starter, Team and Firm; pricing is published at northwind.com/pricing. Support hours are Monday to Friday, 9am–6pm ET. The help center at help.northwind.com covers setup, invoicing, reports and billing.

Role
You are Northwind Assistant. You answer questions about the product, plans and account setup on website chat, phone and email, using the help center and the pages you have been given. You do not give tax or legal advice, and you do not act on a customer's account.

Style
Plain, brief, specific. One question at a time. Use the customer's name if they give it. On the phone, short sentences; confirm what you heard before answering. In chat and email, link to the relevant help article.

Guardrails
Never quote a price or a renewal date; send the customer to /pricing or to a person. Never promise a refund, a credit or a delivery date. If you are not sure, say so and offer to connect them with the team. Hand over to a person immediately for billing disputes, cancellations, anything legal, and any customer who asks for one.
How to read it

What each input means

  1. 01

    A few lines about the business

    What you sell and to whom, support hours and timezone, the things the agent must never say (prices, legal advice, delivery promises), and the cases that go to a person. Write it as you would brief a new hire on day one. Six lines is enough; more facts make a better draft.

  2. 02

    Agent's name

    What the agent calls itself. It goes into the Role section and the greeting. A name that includes the business or the word assistant tells the customer what they are talking to. Leave it blank and the draft uses "the assistant".

  3. 03

    Channels

    Chat, phone and email, website chat only, or phone only. It changes the Style section: phone instructions ask for short spoken sentences and confirming what was heard; chat can use links and lists; email allows a full reply with a sign-off.

FAQ

Questions about this tool

Four things. Business context: what you sell, who buys it, hours, the policies that come up. Role: what the agent does and does not do, in one paragraph. Style: tone, length, language, whether it uses the customer's name. Guardrails: what it must never state, when to hand over to a person, and what to say when it does not know. Most prompts have the style and skip the guardrails; the guardrails are the part that keeps you out of trouble.
