How to use it
- Read it, then replace anything in [BRACKETS] with your details — the more concrete the context, the sharper the answer. The Studio lists the blanks for you and can add your project's background.

- Not sure what it produces? Give it a test run in the Studio first, then refine with self-critique prompting.
