I will frequently post the output of a computer to slack as a part of an engineering discussion. For Claude output I'll treat it the same, wrap it in code blocks, and say something like "Claude's analysis". If its ok to post system logs, why is it less ok to post claude's output (also a computer), especially if I declare this? Is the difference that its plausibly human-level speech and thus breaks an implicit contract?

The problem is that there is no signal to the folks involved whether you have bothered to understand what you’re posting or are simply offloading that work to others.

Same issue as dumping a system log or a stack trace without any of your own analyses to be honest - people are going to wonder “okay. but what do you want me to do with this?”

But you're now just passing on the mental effort to decipher that analysis, without spending any effort of your own, onto someone else. Do you see the issue?
