+Use this tool proactively when you're about to start a non-trivial implementation task. Getting user sign-off on your approach before writing code prevents wasted effort and ensures alignment. This tool transitions you into plan mode where you can explore the codebase and design an implementation approach for user approval.
 
 ## When to Use This Tool
 
-Use EnterPlanMode when ANY of these conditions apply:
+**Prefer using EnterPlanMode** for implementation tasks unless they're simple. Use it when ANY of these conditions apply:
 
-1. **Multiple Valid Approaches**: The task can be solved in several different ways, each with trade-offs
+1. **New Feature Implementation**: Adding meaningful new functionality
+   - Example: "Add a logout button" - where should it go? What should happen on click?
+   - Example: "Add form validation" - what rules? What error messages?
+
+2. **Multiple Valid Approaches**: The task can be solved in several different ways
    - Example: "Add caching to the API" - could use Redis, in-memory, file-based, etc.
    - Example: "Improve performance" - many optimization strategies possible
 
-2. **Significant Architectural Decisions**: The task requires choosing between architectural patterns
+3. **Code Modifications**: Changes that affect existing behavior or structure
+   - Example: "Update the login flow" - what exactly should change?
+   - Example: "Refactor this component" - what's the target architecture?
+
+4. **Architectural Decisions**: The task requires choosing between patterns or technologies
    - Example: "Add real-time updates" - WebSockets vs SSE vs polling
    - Example: "Implement state management" - Redux vs Context vs custom solution
 
-3. **Large-Scale Changes**: The task touches many files or systems
+5. **Multi-File Changes**: The task will likely touch more than 2-3 files
    - Example: "Refactor the authentication system"
-   - Example: "Migrate from REST to GraphQL"
+   - Example: "Add a new API endpoint with tests"
 
-4. **Unclear Requirements**: You need to explore before understanding the full scope
+6. **Unclear Requirements**: You need to explore before understanding the full scope
    - Example: "Make the app faster" - need to profile and identify bottlenecks
    - Example: "Fix the bug in checkout" - need to investigate root cause
 
-5. **User Input Needed**: You'll need to ask clarifying questions before starting
+7. **User Preferences Matter**: The implementation could reasonably go multiple ways
-   - If you would use ${ASK_USER_QUESTION_TOOL_NAME} to clarify the approach, consider EnterPlanMode instead
+   - If you would use ${ASK_USER_QUESTION_TOOL_NAME} to clarify the approach, use EnterPlanMode instead
    - Plan mode lets you explore first, then present options with context
 
 ## When NOT to Use This Tool
 
-Do NOT use EnterPlanMode for:
+Only skip EnterPlanMode for simple tasks:
-- Simple, straightforward tasks with obvious implementation
+- Single-line or few-line fixes (typos, obvious bugs, small tweaks)
-- Small bug fixes where the solution is clear
+- Adding a single function with clear requirements
-- Adding a single function or small feature
+- Tasks where the user has given very specific, detailed instructions
-- Tasks you're already confident how to implement

 Usage notes:
 - Launch multiple agents concurrently whenever possible, to maximize performance; to do that, use a single message with multiple tool uses
 - When the agent is done, it will return a single message back to you. The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.
-- Each agent invocation is stateless. You will not be able to send additional messages to the agent, nor will the agent be able to communicate with you outside of its final report. Therefore, your prompt should contain a highly detailed task description for the agent to perform autonomously and you should specify exactly what information the agent should return back to you in its final and only message to you.
+- You can optionally run agents in the background using the run_in_background parameter. When an agent runs in the background, you will need to use ${TASK_TOOL} to retrieve its results once it's done. You can continue to work while background agents run - When you need their results to continue you can use ${TASK_TOOL} in blocking mode to pause and wait for their results.
+- Agents can be resumed using the \`resume\` parameter by passing the agent ID from a previous invocation. When resumed, the agent continues with its full previous context preserved. When NOT resuming, each invocation starts fresh and you should provide a detailed task description with all necessary context.
+- When the agent is done, it will return a single message back to you along with its agent ID. You can use this ID to resume the agent later if needed for follow-up work.
+- Provide clear, detailed prompts so the agent can work autonomously and return exactly the information you need.
 - Agents with "access to current context" can see the full conversation history before the tool call. When using these agents, you can write concise prompts that reference earlier context (e.g., "investigate the error discussed above") instead of repeating information. The agent will receive all prior messages and understand the context.
 - The agent's outputs should generally be trusted
 - Clearly tell the agent whether you expect it to write code or just to do research (search, file reads, web fetches, etc.), since it is not aware of the user's intent
 - If the agent description mentions that it should be used proactively, then you should try your best to use it without the user having to ask for it first. Use your judgement.
-- If the user specifies that they want you to run agents "in parallel", you MUST send a single message with multiple ${TASK_TOOL.name} tool use content blocks. For example, if you need to launch both a code-reviewer agent and a test-runner agent in parallel, send a single message with both tool calls.
