SMS Qualifier Agent
Replies to missed-call texts, qualifies the lead by SMS, and alerts the owner
I built an SMS agent that fires on a Twilio inbound-SMS webhook when someone texts after a missed call, normalizes the payload, and filters out STOP opt-outs and the owner's own number before doing anything. A GPT-5-mini agent with per-phone conversation memory then qualifies the lead one question at a time (job type, address, name, timing), while a deterministic code-level price scrub guarantees it never quotes a price and never promises a time. When a lead is ready or an emergency is detected it tags the reply with routing tokens, texts the owner a one-line summary, and logs every turn to Google Sheets, keeping the owner as the human in the loop for pricing and booking.
