6 Missed calls last week. You were elbow-deep in a car for all of them.
Three of those callers booked somebody else.
You don't need a developer to fix that. You need one prompt and an AI coding assistant like Claude Code, Cursor, or ChatGPT with access to your site files. Paste the prompt, answer its questions about your business, and it builds the tool.
Here's the one rule that makes this work: describe the job, not the software. "Text everyone whose call I miss within a minute and ask what they need" gets you a working tool. "Build me a CRM" gets you a mess.
The math on one missed call
Say you're a mobile detailer. An average job is $180, and you miss 6 calls a week. If an instant text-back saves just 2 of them, that's $360 a week, or about $18,700 a year. Each text costs around a cent through a provider like Twilio. Run your own numbers before you build anything. If the result is under $50 a month, pick a different problem.
The 10 jobs, and the prompt for each
The same 10 questions, every day. An AI chat widget that answers from your real answers and hands off when it doesn't know. Chat widget prompt
Missed calls going to competitors. An automatic text-back within a minute. Missed-call text-back prompt
Happy customers who never review. An automatic ask after the job, plus an alert on anything under 4 stars. Review request prompt
Leads that go cold after one reply. A spaced follow-up sequence that stops when they answer. Lead follow-up prompt
Phone tag, then a no-show. A booking page with reminders 24 hours and 1 hour out. Booking prompt
A social feed nobody's posted to since March. A drafting assistant built on your past best posts. Social content prompt
Invoices you're too awkward to chase. Polite automatic reminders at 3, 7 and 14 days. Invoice reminder prompt
Answers that only live in your head. A searchable help center built from your emails and DMs. Help center prompt
200 Applications for one opening. A screening form that scores against your must-haves. Keep a human on the final call. Hiring prompt
Competitors changing prices without you noticing. A daily check that alerts you to changes. Price monitor prompt
Every prompt in the full prompt library asks before it builds. It explains the plan, asks how your site is set up, and waits for a yes.
Before you paste a prompt
Pick one job, not three. Build it, use it for two weeks, then pick the next.
Keep API keys on the server. A key in your public site code gets found and abused. OWASP's secrets cheat sheet covers the basics.
Get consent before you text anyone. Automated marketing texts need prior written consent under FCC rules, so a text-back should only answer people who called you. See the FCC's robotext rules.
Check the work. Open the tool on your phone, try to break it, and read what it sends before a customer does.
The hiring prompt deserves extra care. Automated screening can discriminate even when nobody intends it to. Federal anti-discrimination law still applies to an automated screen. Start with the EEOC's employer resources.
