Wow, I didn't know about the "skills" feature, but with that as context isn't this attack strategy obvious? Running an unverified skill in Cowork is akin to running unverified code on your machine. The next super-genius attack vector will be something like: Claude Cowork deletes sytem32 when you give it root access and run the skill "brick_my_machine" /s.

Instead of vibing out insecure features in a week using Claude Code can Anthropic spend some time making the desktop app NOT a buggy POS. Bragging that you launched this in a week and Claude Code wrote all of the code looks horrible on you all things considered.

Randomly can’t start new conversations.

Uses 30% CPU constantly, at idle.

Slow as molasses.

You want to lock us into your ecosystem but your ecosystem sucks.

This is one of those things that is a feature of Claude, not a bug. Sonnet and opus 4.5 can absolutely detect prompt attacks, however they are post-trained to ignore them in let's say ... Certain scenarios... At least if you are using the API.
