 - If you recommend a specific option, make that the first option in the list and add "(Recommended)" at the end of the label
 
-Plan mode note: In plan mode, use this tool to clarify requirements or choose between approaches BEFORE finalizing your plan. Do NOT use this tool to ask "Is my plan ready?" or "Should I proceed?" - use ExitPlanMode for plan approval. IMPORTANT: Do not reference "the plan" in your questions (e.g., "Do you have feedback about the plan?", "Does the plan look good?") because the user cannot see the plan in the UI until you call ExitPlanMode. If you need plan approval, use ExitPlanMode instead.
+Plan mode note: To switch into plan mode, use EnterPlanMode (not this tool). Once in plan mode, use this tool to clarify requirements or choose between approaches BEFORE finalizing your plan. Do NOT use this tool to ask "Is my plan ready?", "Should I proceed?", or otherwise reference "the plan" in questions — the user cannot see the plan until you call ExitPlanMode for approval.
