+- **Git Worktree Detection:**
+  - Now properly skips Git initialization when inside existing Git worktree
+  - Prevents accidental nested repository creation
+- **Flag System Overhaul:**
+  - `--git`/`--no-git` controls repository initialization
+  - `--aliases`/`--no-aliases` consistently manages shell alias creation
+  - `--git-tasks`/`--no-git-tasks` controls whether task files are stored in Git
+  - `--dry-run` accurately previews all initialization behaviors
+- **GitTasks Functionality:**
+  - New `--git-tasks` flag includes task files in Git (comments them out in .gitignore)
+  - New `--no-git-tasks` flag excludes task files from Git (default behavior)
+  - Supports both CLI and MCP interfaces with proper parameter passing
+
+**Implementation Details:**
+- Added explicit Git worktree detection before initialization
+- Refactored flag processing to ensure consistent behavior
+
+- Fixes #734
