It's extraordinarily hit or miss. I've tried giving instructions to be concise, to only give high level answers, to not include breakdowns or examples or step-by-step instructions unless explicitly requested, and yet "What are my options for running a function whenever a variable changes in C#?" invariably results in a bloated list with examples and step-by-step instructions.

The only thing that changed in all of my experimentation with various saved instruction was that sometimes it prepended its bloated examples with "here's a short, concise example:".
