The grok-cli is on github[0] there is nothing that I can see in the code that is activily looping ~/ and uploading everything.

My two guesses would be one the LLM decided it needed these files for the task or two the user simple asked grok to do it so they could post the tool calls on twitter.

That is not the Grok CLI being discussed. That's an open source, third party CLI. https://x.ai/cli is the official Grok CLI being discussed, and it is not open source.
