+*   **CLI Command:** `task-master remove-task [options]`
+*   **Description:** `Permanently remove a task or subtask from the Taskmaster tasks list.`
+*   **Key Parameters/Options:**
+    *   `id`: `Required. The ID of the Taskmaster task (e.g., '5') or subtask (e.g., '5.2') to permanently remove.` (CLI: `-i, --id <id>`)
+    *   `yes`: `Skip the confirmation prompt and immediately delete the task.` (CLI: `-y, --yes`)
+    *   `file`: `Path to your Taskmaster 'tasks.json' file (default relies on auto-detection).` (CLI: `-f, --file <file>`)
+*   **Usage:** Permanently delete tasks or subtasks that are no longer needed in the project.
+*   **Notes:** Use with caution as this operation cannot be undone. Consider using 'blocked', 'cancelled', or 'deferred' status instead if you just want to exclude a task from active planning but keep it for reference. The command automatically cleans up dependency references in other tasks.

 ## Configuration & Metadata
 
 -   **Environment Variables**: Taskmaster relies on environment variables for configuration (API keys, model preferences, default settings). See [`dev_workflow.mdc`](mdc:.cursor/rules/dev_workflow.mdc) or the project README for a list.
--   **`tasks.json`**: The core data file containing the array of tasks and their details. See [`tasks.mdc`](mdc:.cursor/rules/tasks.mdc).
+-   **`tasks.json`**: The core data file containing the array of tasks and their details. See [`tasks.mdc`](mdc:.cursor/rules/tasks.mdc) for details.
 -   **`task_xxx.md` files**: Individual markdown files generated by the `generate` command/tool, reflecting the content of `tasks.json`.
