If `list_roblox_studios` is available, call it once. Keep the matching Studio name and `studio_id` for later context inspection or Studio-fallback writes. 2. If the runtime explicitly reports that the Roblox Studio MCP server/tool is missing or unconfigured, follow [`../../references/roblox-mcp-setup.md`](../../references/roblox-mcp-setup.md): stop this turn and ask whether the user wants client-specific setup. Do not continue the original task or make writes while waiting for that answer. 3. If the server is configured but the call fails because Studio is closed, disabled, or returns no connected Studio, report `Roblox Studio MCP is not conn
