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!

Not working for me, please fix this ASAP

This is an important issue affect user productivity. Can this be prioritized?

need this looked at as soon as possible please

I found today that this issue has been resolved. Please help verify it and also report back if it's still not fixed.

for me only AskUserQuestion would trigger the notification hook, any other permission asking to run Bash or read file would not trigger notification still

@cookiejoo I'm seeing the same behavior.

It doesn't seem to work in my environment either.

same here. 10 weeks old, no one cares?

I'm experiencing the same issue. I analyzed the VSCode extension source code and found the root cause.

Environment

| Item | Value |
|------|-------|
| Host OS | Ubuntu Server (Linux 6.5.0-45-generic) |
| Claude Code CLI | 2.1.19 |
| Claude Code VSCode Extension | 2.1.19 |

| Connection Method | VSCode Remote SSH from Mac/Windows |

Setup Details

[Local PC (Mac/Windows)]              [Ubuntu Server]
         VSCode  ──── SSH Connection ────→  Claude Code CLI (installed)
           │                                       ↑

                                        (runs on server, invokes CLI)

• Claude Code CLI is installed on the Ubuntu server
• Local PC connects to Ubuntu server via VSCode Remote SSH extension
• Claude Code VSCode extension runs on the server side and invokes the Claude Code CLI on the server
• All hook scripts are executed on the Ubuntu server

Hook Behavior in My Environment

I have configured hooks for all available events:

| Hook | Terminal CLI | VSCode Extension |
|------|--------------|------------------|
| PreToolUse | Works | Works |
| PostToolUse | Works | Works |
| UserPromptSubmit | Works | Works |
| Stop | Works | Works |
| SubagentStop | Works | Works |
| SessionStart | Works | Works |
| SessionEnd | Works | Works |
| PreCompact | Works | Works |
| Notification | Works | Does NOT fire |
| PermissionRequest | Works | Does NOT fire |

Root Cause

Missing Subtype Handlers in processControlRequest()

The processControlRequest() method only handles 3 subtypes:

async processControlRequest(e,r){
  if(e.request.subtype==="can_use_tool"){
    // Implemented - handles tool permission requests
    return{...await this.canUseTool(...),toolUseID:e.request.tool_use_id}
  }else{
    if(e.request.subtype==="hook_callback"){
      // Implemented - handles PreToolUse/PostToolUse hooks
      return await this.handleHookCallbacks(e.request.callback_id,e.request.input,...)
    }
    if(e.request.subtype==="mcp_message"){
      // Implemented - handles MCP messages
    }
  }
  throw Error("Unsupported control request subtype: "+e.request.subtype)
  // Notification and PermissionRequest reach here and throw error
}

Subtype Support Matrix

| Subtype | Handler Method | Status |
|---------|---------------|--------|
| can_use_tool | canUseTool() | Implemented |
| hook_callback | handleHookCallbacks() | Implemented |
| mcp_message | MCP handler | Implemented |
| Notification | - | Not implemented |
| PermissionRequest | - | Not implemented |

Why PreToolUse/PostToolUse Work

These hooks are sent as hook_callback subtype and processed by handleHookCallbacks():

handleHookCallbacks(e,r,n,s){
  let i=this.hookCallbacks.get(e);
  if(!i)throw Error(`No hook callback found for ID: ${e}`);
  return i(r,n,{signal:s})  // Executes registered callback
}

Why Notification/PermissionRequest Don't Work

These are sent as separate subtypes (Notification, PermissionRequest) but there's no handler for them in processControlRequest(). They fall through to the final throw Error() statement.

Processing Flow Comparison

[PreToolUse/PostToolUse (works)]
CLI -> control_request(subtype="hook_callback") -> handleHookCallbacks() -> User hook executed

[Notification/PermissionRequest (doesn't work)]
CLI -> control_request(subtype="Notification") -> processControlRequest() -> No handler -> Error

Regarding Recent Reports

@easonfg reported on 1/17 that "only AskUserQuestion triggers the notification hook". This suggests AskUserQuestion may use a different code path. Further investigation may be needed to understand this partial behavior.

---

Suggested Fix

Adding handlers for Notification and PermissionRequest subtypes in processControlRequest() should resolve this issue:

async processControlRequest(e,r){
  // ... existing handlers ...

  // Add these handlers:
  if(e.request.subtype==="Notification"){
    return await this.handleHookCallbacks(/* Notification hook params */);
  }
  if(e.request.subtype==="PermissionRequest"){
    return await this.handleHookCallbacks(/* PermissionRequest hook params */);
  }

  throw Error("Unsupported control request subtype: "+e.request.subtype)
}

Analyzed File

~/.vscode-server/extensions/anthropic.claude-code-2.1.19-linux-x64/extension.js

Please fix this ASAP. Still not fixed on Claude Code VSCode Extension 2.1.22, VSCode 1.108.2

Same issue here, it's been a while...

Has this been fixed?

PermissionRequest hooks are now supported in the IDE:

{
  "hooks": {
"PermissionRequest": [
  {
    "hooks": [
      {
        "type": "command",
        "command": "powershell.exe -Command \"[console]::beep(1000, 500)\"",
        "async": true
      }
    ]
  }
]
  }
}

Thanks @blois ! Can confirm it works for me!

Going to close this issue out- PermissionRequest notifications should be working and right now we do not have plans to support the Notification hook from the IDE- the semantics of this hook are fairly tied to the TUI.

@blois It's still not firing. My notification script hasn't fired when I got this. It's the Permission hook that's not working.

@ivanjuras an additional fix should be arriving shortly.

Hi, thanks for your actions. Is it planned to have native windows notification via VSCode extension when Opus needs our input or has finished working ?
