What's Wrong?

When I try to insert a snippet into the Claude Code chat box in Visual Studio Code by using the Snippets: Insert Snippet option from command palette (CMD + Shift + P) it gets inserted into the cursor position in the active document, instead of the chat box.

This occurs regardless of what mode is selected (plan, auto accept, ask before edit.)

What Should Happen?

It should be inserted into the chat box, not the active document, this is how the GitHub CoPilot chat window functions.
