What changes in Claude's response
Claude first tells you why your prompt is bad ('too vague — you didn't say what code, what error, what you've tried'), then writes a better version of your prompt, then runs it. You learn how to prompt better and get a useful answer in one turn instead of a 5-message back-and-forth.
When NOT to use PROMPTFIX
Don't PROMPTFIX prompts that are already good. It'll second-guess them and make them worse.
