 # Superset Monorepo Guide
 
+You're running inside a Superset workspace — an isolated git-worktree copy of this repo. "Workspace" in any user message refers to this, not VS Code/editor workspaces.

 ## Question Tool
 
 When you need to ask the user ANY question — including simple yes/no, confirmations, and clarifications — ALWAYS use the `ask_user` tool. Never ask questions in plain text. The Superset UI renders `ask_user` calls as an interactive overlay with clickable option buttons; plain-text questions will not be surfaced to the user in the same way.
