    "incantation": "When adding a workspace in a Git-backed repository, use `jj workspace add --colocate <destination>` to create a corresponding Git worktree or `--no-colocate` to prevent one; without either flag, creation depends on whether the current workspace is colocated and `git.colocate` is true.",
