The model has no judgment or common sense, it has no idea that sending the email address would be a problem. I don't want it to come back to me when it's building software and gets stuck on something, I expect some independent troubleshooting and to power through, which it did in this context by adding the email address in the request. This is solved by setting the model instructions correctly, the problem is we don't know when it is going to try some new problematic behavior like this.
