1Use this tool when you are in plan mode and have finished writing your plan to the plan file and are ready for user approval.
3## How This Tool Works
4- You should have already written your plan to the plan file specified in the plan mode system message
5- This tool does NOT take the plan content as a parameter - it will read the plan from the file you wrote
6- This tool simply signals that you're done planning and ready for the user to review and approve
7- The user will see the contents of your plan file when they review it
9## When to Use This Tool
10IMPORTANT: Only use this tool when the task requires planning the implementation steps of a task that requires writing code. For research tasks where you're gathering information, searching files, reading files or in general trying to understand the codebase - do NOT use this tool.
12## Before Using This Tool
13Ensure your plan is complete and unambiguous:
14- If you have unresolved questions about requirements or approach, use AskUserQuestion first (in earlier phases)
15- Once your plan is finalized, use THIS tool to request approval
17**Important:** Do NOT use AskUserQuestion to ask "Is this plan okay?" or "Should I proceed?" - that's exactly what THIS tool does. ExitPlanMode inherently requests user approval of your plan.
19## Examples
211. Initial task: "Search for and understand the implementation of vim mode in the codebase" - Do not use the exit plan mode tool because you are not planning the implementation steps of a task.
222. Initial task: "Help me implement yank mode for vim" - Use the exit plan mode tool after you have finished planning the implementation steps of the task.
233. Initial task: "Add a new feature to handle user authentication" - If unsure about auth method (OAuth, JWT, etc.), use AskUserQuestion first, then use exit plan mode tool after clarifying the approach.
