What's Wrong?

I use both cowork and Visual Studio Code with Claude code but I've never received such error on Visual Studio Code

This error happens only on Cowork

Autocompact is thrashing: the context refilled to the limit within 3 turns of the previous compact, 3 times in a row. A file being read or a tool output is likely too large for the context window. Try reading in smaller chunks, or use /clear to start fresh.

What Should Happen?

No such error like VSC
