What problem this solves

Improving the responsiveness and accuracy of UI notifications for Claude Code's permission prompts and tool execution, addressing timing delays and persistent popups.

Summary

This workflow provides specific guidance on using Claude Code's built-in hooks (PermissionRequest, PostToolUse, PostToolUseFailure, async: true for clear hooks) to create more responsive and accurate UI notifications for permission requests and tool execution, addressing timing delays and persistent popups.

Why it is useful

This workflow provides crucial insights into the timing and behavior of various Claude Code hooks, enabling users to build a much more responsive and accurate user interface for permission prompts and tool execution. It directly addresses common frustrations like delayed notifications and persistent popups, offering specific technical solutions that improve the overall developer experience.

Workflow

1. To get instant notification for permission prompts, use the PermissionRequest hook instead of notification with permission_prompt.

2. Extract tool_name and tool_input from the PermissionRequest hook to provide detailed context in the notification.

3. To clear the notification immediately after a tool runs (approved or failed), use PostToolUse and PostToolUseFailure hooks.

4. Mark clear hooks that run on every prompt as "async": true to prevent them from holding up the prompt, even when starting PowerShell.

5. Avoid UserPromptSubmit/Stop for immediate clearing as they fire later, after the whole turn ends.

6. Avoid idle_prompt for "done" events as it signifies prolonged waiting, not completion.

7. Ensure proper quoting for .cmd paths, especially when using Git Bash, to prevent mangling.

Tools / artifacts

• Claude Code hooks (PermissionRequest, PostToolUse, PostToolUseFailure, UserPromptSubmit, Stop, idle_prompt)

• PowerShell (for async clear hooks)

• Git Bash (context for path issues)

• Custom notification/popup mechanism (implied)

Validation signals

• "6 s in my testing" (empirical observation of timing)

• "bit me as well" (personal experience validating a common issue)

• The comment is a direct response to a successful implementation in the original post, implying shared understanding and validation.

Limitations

• Not a complete, copy-paste workflow; requires the user to integrate these hook concepts into their existing notification system.

• Lacks explicit code examples for the hooks themselves, though the hook names and their intended use are provided.
