I think you should embrace a bit of ambiguity. Don't treat this like a stupid computer where you have to specify everything in minute detail. Certainly the more detail you give, the better to an extent. But really: Treat it like you're talking to a colleague and give it a shot. You don't have to get it right on the first prompt. You see what it did and you give it further instructions. Autocomplete is the least compelling feature of all of this.
Also, I don't remember what model Copilot uses by default, especially the free version, but the model absolutely makes a difference. That's why I say to spend the $20. That gives you access to Sonnet 4 which is where, imo, these models took a giant leap forward in terms of quality of output.
