 - `--merged`: Remove worktrees whose branches have merged PRs/MRs (also deletes the branch)
 - `--dry-run`, `-n`: Preview changes without removing
 - `--yes`, `-y`: Non-interactive mode (skip confirmation prompts)
+- `--force`: Force removal even if worktree has uncommitted changes or untracked files
 
 **Note:** The `--merged` mode auto-detects your hosting provider (GitHub or GitLab) from the `origin` remote URL and requires the corresponding CLI tool (`gh` or `glab`) to be installed and authenticated. For self-hosted instances, set the provider explicitly: `git gtr config set gtr.provider gitlab`.
