if you're still looking and it's a js/ts project, I can help. I'll use a shit ton of AI, but not when talking to you. my email is on my profile. twitter account with the same username.
I think this whole thing sucks.. we should have a single way of setting these instructions that all agents will read. not sure why they feel they need to own that part. seems so petty. do you think something like this would be useful? https://github.com/luisrudge/dot-ai/ basically a cli that generates files for multiple AI tools based on a single source
It helps to prevent scams because you know who the money is going to (not foolproof, of course).
CPF in Brazil is not as fragile or sensitive as the SSN in the US. You can't easily wreck someone's life just because you know their name and CPF. CPF numbers are shared pretty much everywhere since it's a unique identification code for a single person. All businesses ask for it when they're generating invoices/receipts etc. You basically use your CPF everywhere and there's virtually no risk in sharing it.
That's not to say that identity theft is not a thing in Brazil. It definitely is, however the damage is usually not as bad as the stories you hear in the US and the blame is usually put on the banks / service providers for not doing the proper KYC to verify the documents. It'll be a headache for the person, but usually something that is quickly fixed.
