Prompt library
Copy, swap the [brackets], use. Every prompt here is a working template for something people actually do — replying to email, researching a decision, writing a post that isn’t slop, generating an image that matches the one in your head.
Tool tags mark where a prompt is known to work well. Any means it is tool-agnostic — the technique does not depend on the vendor. If you want to understand why these are shaped the way they are, read the course.
