No one knows that Claude has hundreds of hidden commands that completely change everything. For example, at the start of your prompt, if you use /ghost, it's gonna strip away all of the AI giveaways, making you sound way more human. Then /l99, this will make Claude sound like a high level expert from any industry.
/mirror makes Claude match its writing style with your sentence structures and vocabulary. /deepthink forces Claude to reason and question itself to give you the most accurate answer. Then my favourite, /godmode.
This gives you the most in depth detailed and most complete answer that Claude can possibly give you. Now just comment PROMPT and I'll send you the full library and exactly what they do.
