What they did
For a seven-location, mostly delivery sushi chain where ~90% of orders arrive as Instagram DMs, he wired Meta API webhooks to Claude Sonnet 4.6 with menu, allergens, delivery zones, hours, prep times, and promos. The agent chats, helps pick rolls, flags allergens, upsells when fitting, then pushes confirmed orders to the kitchen and writes CRM plus owner-analytics records. Prompt caching keeps the large shared context cheap on ~97% of messages.
How it went
He reported roughly 98% correctness and that cache reads cut the bulk of context cost to about a tenth of normal input pricing, making Sonnet affordable for every DM.
Worth knowing
Calls, voice notes, and photos stay with humans on purpose; plain-text handoff is mainly when the customer asks for a manager. The post is the builder's own production write-up on r/AI_Agents.
