Open your one home base
You are going to keep everything for all three nights in ONE place so nothing gets lost. Open a fresh Google Doc and title it Your Name - Agent Design Brief. Drop in six headings right now, each on its own line: AGENT NAME, WHO IT SERVES, THE ONE JOB, VOICE AND TONE, SAFETY RULES, MUST HANDLE. Leave a few blank lines under each one. This doc is your home base. Anything I have you write tonight goes under one of these headings, and tomorrow when we build for real, you will copy straight out of this doc into the tool. Quick heads up on tools so nobody is surprised: tomorrow we build in Claude, the app you installed in setup, because its Projects feature gives you the cleanest way to actually feel like you built an agent. It is free, no card. Google AI Studio and ChatGPT are right there as options too, and AI Studio is the one that will not throttle a full room, so keep a Google login handy as your backup. You do not need to open any of them tonight. Everything we decide tonight lives in this Google Doc.
