Your first move: open the current Weekly Build Challenge in Classroom and post the proof prompt shown there. your first proof can be rough. it cannot be vague. new here? reply with: 1. the business job you want AI to perform. 2. the current baseline. 3. the receipt that would prove it worked. let's fucking build. with receipts.
