Bad communication => being too ambiguous, expecting LLM to understand you through that ambiguity and then not being satisfied when it didn't.

Bad communication: "My webapp doesn't work"

Good communication: "Nextjs, [pasted error]"

Bad communication is giving irrelevant information, or being too ambiguous, not providing enough or correct detail.

Then another example of good communication and efficiency in my view is for example "ts, fn leftpad, no text, code only".

I myself can understand what it means when someone was to prompt it and LLM can understand such query for all domains.

Although if I was using Copilot I would just write the bare minimum to trigger the auto complete I want so

const leftPad =

is probably enough.
