Build an AI greeter with Coze, from a first version that flops all the way to one you can copy.
Xiaoming builds an AI greeter in Coze, and the first version's welcome message is addressed to... Manman. It turns out an old demo deck had been used as the material for this event.
The episode fixes it step by step with five moves. Spell out what it does, what it hands over, and what it doesn't do. Label every document with its source, and make it actually read them when it answers. Hand numbers that change, like the guest count, to a tool that works them out on the spot: add one name to the list and the count goes to 17; undo it and it's back to 16. Only then is it really connected. Pair each draft with a six-box checklist: who, how many, where, when, what, and source. Finally, test it with three questions, including one about something that isn't in the material, to see whether it dares to say "can't confirm."
The episode walks through every build step, so you can follow along with your own task in place of the example.
