claude-code [BUG] Notification hook does not fire in VSCode extension

Preflight Checklist

[x] I have searched existing issues and this hasn't been reported yet
[x] This is a single bug report (please file separate reports for different bugs)
[x] I am using the latest version of Claude Code

What's Wrong?

The Notification hook does not fire in the VSCode extension version of Claude Code.

Actual Behavior

Permission dialog is displayed as expected
However, the Notification hook does not fire
No log file is created by the hook command
PreToolUse and Stop hooks work correctly

What Should Happen?

Expected Behavior

According to the documentation (https://code.claude.com/docs/ja/hooks#notification), the Notification hook should fire in the following cases:

When Claude Code requests permission to use a tool
When the prompt input has been idle for at least 60 seconds

Error Messages/Logs

None

Steps to Reproduce

Configure a Notification hook in settings.json with a command that logs to a file
Reload VSCode window
Configure permissions.ask to require confirmation for specific tools (e.g., Bash)
Execute a tool that triggers the permission dialog

sample_settings.json

Claude Model

Sonnet (default)

Is this a regression?

I don't know

Last Working Version

No response

Claude Code Version

2.0.35 (Claude Code)

Platform

Anthropic API

Operating System

Windows

Terminal/Shell

Windows Terminal

Additional Information

When the permission dialog was displayed, the Notification hook did not execute
The log file specified in the command was never created
Other hooks (PreToolUse, Stop) work as expected
Workaround: Using PreToolUse hook with matcher "Write|Edit|Bash|NotebookEdit" to achieve similar functionality
Unclear if this issue exists in the CLI version
This may be specific to the VSCode extension

For privacy, the commands have been removed, but in reality the command contents are written.

In my case, it seems to have been resolved by updating VSCode to 1.105.1 and restarting. I’d like to monitor it a bit longer.

Confirming this on Win11 as well.

The Claude CLI does trigger the Notification hook, but the Claude Code extension does not.

OS Name Microsoft Windows 11 Pro Version 10.0.26100 Build 26100 VSCode Version: 1.105.0 Claude Code Extension Version: 2.0.35

Unfortunately updating to VSCode 1.105.1 and restarting ( VSCode, and the system ) did not resolve the problem.

Thank you all for reporting this issue.

I also tested it with VSCode 1.105.1 in my environment, but the Notification hook did not work.

It also doesn't work for me. Please, someone fix this.

i was very sad to learn about this bug. losing a lot of efficiency by having to watch Claude in case it asks me for something OR have it sit idle for some time because I'm doing something else and didn't notice

me too!!!

This is affecting me as well

It would be great if this were fixed; it would also be great if there were an option to allow the VSCode extension to use VSCode's native notifications for Claude Code notifications.

I have an alternative solution : Is Use Terminal !

Open Claude Code -> click 。。。 -> Configure Editor -> input：Use Terminal -> choose：Use Terminal

@cookiejoo This is not a solution. It's a workaround and a poor one.

The VS Code extension can do things the terminal doesn't, that's why we use it.

I know, bro! It's just that when you need a hook to solve some indispensable problems, it's a choice you have to make. Hope the official will respond!
