 - **Menu bar only:** The app has no main window (`LSUIElement = YES`). All UI is in the MenuBarExtra popover.
 - **Commit discipline:** Each commit should be a logical unit of work with a descriptive message.
 
+## Git Workflow
+
+- **Default workflow:** Commit and push directly to `main` when working in the primary checkout.
+- **No separate PR/branch by default:** Do not create feature branches or pull requests unless explicitly requested.
+- **Worktree exception:** When working from a git worktree, use a separate branch for that worktree. Open a PR only if that worktree-based flow needs one.
+
 ## Testing Guidelines
 
 - **Always update or add tests when modifying code.** Any change to models, services, or utilities must include corresponding test updates in `TaskMenuTests/`.
