We set up an agent harness — Claude Code, a Rasa MCP server, and some markdown files — and use it to build a flight upgrade assistant from scratch, live on camera.
The airline bot on WhatsApp is actually pretty slick. You’re already logged in, your bookings are there. But the conversation feels like filling in a form. Say anything off-script and it’s lost.
So we build something better: an upgrade agent that can check availability, show seats, quote prices, and handle hesitation naturally. "That’s a lot" doesn’t break it — it re-asks.
The whole thing is built in one sitting using Claude Code with Rasa’s MCP tools. No slides, no prep.

– Claude Code (the base)
– Rasa MCP tools (train, test, inspect — without leaving the editor)
– CLAUDE.md (workflow instructions that make Claude Code self-validating)
