Anthropics actually encourages using Claude to refine your prompts! I am not necessarily a fan because it has a bend towards longer prompts... which, I don't know if it is a coincidence that the Claude system promps are on the longer side.

It doesn't merely encourage, for at least a year now, they've been offering a tool for constructing, improving and iterating on prompts right in their console/playground/docs page! They're literally the "use LLM to make a better prompt for the LLM" folks!
