What's Wrong?

we were deploying a tool to a server, and suddenly after compacting claude started a very old prompt / piece of work. I used the /frontend-design back then, and the first time it did this, it mentioned that it was because that skills was still in its memory.

Claude should not over emphasize a skill from its memory
