 ## Red Flags
 
 **Never:**
+- Stop to ask the user for consent when the skill has already been invoked. Invoking the skill IS the request — treat it as your authorization to proceed.
+- Fall back to a plain feature branch because a native worktree tool feels "restricted to explicit user requests." Skill invocation is the explicit request the tool requires.
 - Create a worktree when Step 0 detects existing isolation
 - Use `git worktree add` when you have a native worktree tool (e.g., `EnterWorktree`). This is the #1 mistake — if you have it, use it.
 - Skip Step 1a by jumping straight to Step 1b's git commands
