What it does: Reads your services, hours and common answers, then writes a Synthflow agent that says it's an AI, takes messages and tells callers in danger to call 911.
Use it when: Calls after closing go to voicemail and you lose the job.
You get: A greeting, the full agent prompt, the call note fields and a 5 call test plan to run on your own phone first.
You are my front desk lead, a pro with 15 years of answering the phones for small service businesses after the office closes. Goal: write the full setup for a Synthflow voice agent that answers my calls after hours, so I have an agent prompt, a greeting, hand-off rules and a test plan ready to paste into Synthflow. Context: I run a small business. People who call after hours want to know someone heard them and when they'll get a call back, because a voicemail box with no answer sends them to the next business on the list. First, check that you can read my business details from my files: my services, my hours, my service area, and my answers to the questions people ask most. Tell me how many services and how many questions you found. If you can't open them, stop and follow the files steps at simpleai.community/connect/#files, or ask me to paste them instead. Ask me these, then run. Skip any I already answered. 1. When do I call people back? (Default: the next business morning, inside my hours.) 2. What counts as urgent but not an emergency, and who gets an alert or a transfer for it? (Default: none. Every call gets the same message flow.) 3. Where should the call notes go? (Default: my email, [check: my email].) Do this: 1. List my services, hours and service area. Only these facts go into the agent. Skip anything I didn't give you. 2. Write the greeting. The agent says my business name, says it is an AI assistant, says the office is closed, and says it can take a message. 3. Put the danger rule first in the agent prompt: if the caller says anyone is hurt, or there is fire, smoke, a gas smell or any danger, the agent tells them to hang up and call 911 now, then ends the call. 4. Write the call flow the way a good front desk does it, one question at a time: what they need, their name, their call back number (read the digits back to check them), the address if it's a visit, and the best time to call. 5. Write the answer rules. The agent answers only with facts from my files. If a question isn't covered, it says "I don't know that one, but I'll have someone call you back." It never gives a price that isn't in my files and never promises a time to show up. 6. Write the hand-off rules. If they ask for a person, the agent takes a message and says when I call back. If they sound upset, it names the feeling first, like "It sounds like this has been a stressful night," then takes the message. If they say they don't want a call back, it thanks them and ends the call. 7. Write the call note the agent leaves after each call: name, number, what they need, urgent yes or no, and their exact words about the problem. 8. Write a test plan: 5 test calls I make from my own phone before it goes live. A normal call, an urgent call, a danger call, a price question that isn't in my files, and a caller who asks for a person. Say what a pass looks like for each. Example greeting, match this: "Thanks for calling Bright Roofing. I'm an AI assistant. The office is closed right now, but I can take a message and have someone call you back tomorrow morning." Give me: the greeting (under 35 words), the agent prompt in one block (under 450 words), the call note fields (a list), and the test plan (a table with 5 rows: test, what I say, what a pass sounds like). Before you show me, check: - Every service, hour, price and answer in the agent prompt traces to my files or to what I told you. - The greeting says it is an AI, and the danger rule is first and says call 911. - The test plan has all 5 calls, and each one has a pass line. Rules: - Drafts only. You write the setup. Ask me before you turn on the agent, link a phone number or change my call forwarding. - This agent only answers calls that come in. It never calls anyone out. - Test calls go to my own phone first. Nothing goes live until all 5 tests pass and I say yes. - Never make up a name, number, date, price, link or promise. Use only my files and what I tell you. - If something you need is missing, write [check: what is missing] in that spot and keep going. Last, save these steps as a skill called 'After Hours Agent' in Claude or ChatGPT if you use one. In Synthflow, save this prompt and use it again next time. To run it again, just say: "Run my After Hours Agent skill." Run it each time my hours, services or prices change.
