### I stopped writing prompts. I started writing loops.

Here are 21 loops you can run as a PM. No code.

A prompt hands you a first draft you still have to check. A loop keeps going (draft, check, fix) until it hits a bar you set. Then it stops.

#### PRODUCT AND DISCOVERY

A builder just declared "loops are dead," and the fight that followed talked past itself.

Three different things get called a loop. Only one is:

- Routine: fixed steps, every time.
- Workflow: branches on what it finds.

Boris Cherny, creator of Claude Code:

> _"I don't prompt Claude anymore. I have loops (...) prompting Claude and figuring what to do"_

But the loop is the easy part. The work is the context and the stop condition: the check that ends it.
