Please help me give the prompt below a checkup, with the goal of making it shorter and clearer without changing the meaning:
1. Identify repeated rules, conflicting requirements, outdated information, and requirements that make you write extra filler; list them one by one and explain why;

4. Finally, tell me roughly how many characters there are before and after slimming down.
