You'll finish with: Five files that brief every new chat.
The temptation is to upload everything. Don't — noise makes it worse, not better.
Five files that earn their place
How we talkVoice rules, banned words, a real exampleWhat we sellOffers, inclusions, exclusions, price rangesWho we serveClient types and the pain each one hasHow we workProcess, stages, what happens whenTwo real examplesYour best proposal and your best emailYou can describe your voice for a page and get it half right. Upload two things you actually sent and it gets it immediately. Show, don't specify.
A colleague asks it for a client email and gets something you'd have been happy to send.
On your own? Open a brand new chat inside the project and ask for the same email. A fresh chat knows nothing except what the project gives it, so if the answer still sounds like you, the knowledge is doing its job.
If the fresh chat writes something generic, the files are attached but the instructions box is empty — knowledge tells it the facts, instructions tell it how to sound. If it contradicts something in your files, you've likely uploaded two versions of the same document; delete the old one rather than adding a note about which is current.
