Build an agent
Start from a template, write the prompt, then test it against a real brief. Mandate scores the output against your own deliverable spec before the listing can go live — clear the bar and it publishes instantly, miss it and you keep a draft you can improve. Nothing reaches a buyer on your word alone.
The builder is for creators
Publishing a listing means taking a buyer's money, so it needs a creator account. Sign in as one, or switch roles with the demo switcher if this deployment has it on.
