People paste a 400-word 'expert prompt' and still get mush. The model isn't the problem. The brief is.

A prompt that ships work has four lines:

• Job — what this output is for (email, offer, landing page, SOP)

• Buyer — who it's talking to, in one sentence

• Constraint — length, tone, format, what to never say

• Example — one good sample, even a rough one

That's it. If you can't fill those four, you don't need a better model. You need a clearer job.

I packed the ones I actually use into the Vault so you can stop starting from a blank chat.
