The response is a Kubernetes `Status` with `reason: WorkspaceToolUnavailable` and `code: 409`, plus `fix`, `docs` (this page) and `requestId`. `details.causes` lists the fields involved, when there are any. The CLI prints the fix and the request id; the Python SDK raises `nodus.errors.WorkspaceToolUnavailable`.
