This reference documents how global (system-wide) modes work, where they live, and how they interact with workspace-scoped modes. .roomodes Per-workspace (project) modes Global custom modes settings file (stored in VS Code globalStorage; exact path is environment-specific) System-wide modes for Roo Code This file is created automatically on Roo Code startup if it does not exist. When a mode with the same slug exists in both locations, the workspace (.roomodes) version takes precedence. Editing the global mode may have no visible effect inside a workspace that overrides the same slug. To change behavior in one repo only, prefer editing .roomodes. Default to editing .roomodes unless the user explicitly requests global scope. If the user asks for global scope, first check whether a workspace override exists for the same slug. If it does, explain the precedence and offer to edit both. Prefer minimal, targeted changes and preserve YAML formatting.
