[REGRESSION] Hook response fields user_message / agent_message still ignored in Windows v2.0.77

[Chris_Drake]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Claude is not seeing any response from my hooks (in debugging - I tried every hook - none work).

Steps to Reproduce

Make a hook that returns a message.
Ask Claude to trigger it, and ask if it saw any message.

Expected Behavior

Claude should see every agent_message response that’s coming back from our hook calls.

Does this stop you from using Cursor

No - Cursor works, but with this issue

[Chris_Drake]

UI does show the hook returning data. Claude says:-

Perfect! I can see the hook output is working!

Looking at your screenshot:

• user_message: “[Hook Test] beforeMCPExecution at 2025-11-14 19:58:10”
• agent_message: “HOOK_MESSAGE from beforeMCPExecution hook - Can you see this AI?”

The hook is firing and returning the correct JSON with agent_message, BUT I’m still not seeing it in my context. This confirms:

1. Your hook script is working perfectly with snake_case
2. Cursor is receiving and displaying the output
3. But agent_message is NOT being passed to me (the AI)

This means either:

• There’s still a bug in Cursor 2.0.77 where agent_message doesn’t reach the AI
• Or agent_message works differently than expected (maybe only for certain hooks or contexts)
• Or it’s only added to context at specific points (like the next message)

Good idea to post on the forums! When you do, you can show:

• The hook is executing correctly
• The output JSON is valid with correct snake_case
• user_message appears in UI
• agent_message doesn’t reach the AI’s context

This will help the Cursor team identify if it’s a bug or if the feature works differently than documented.

Hooks are now completely broken!

The IDE 2.1.42 says it’s calling the hook (see screenshot), however, it does NOT perform the call at all (my hook code is never run, and does not log anything), and does not give any error.

Version: 2.1.42 (system setup)
VSCode Version: 1.105.1

It was running and logging fine yesterday morning, but I did upgrade to 2.1.41 yesterday as well, and it looks like that version also broke hooks entirely

Here’s the last 2 lines of my logfile my hook writes out:

{“timestamp”: “2025-12-01 10:43:08”, “event”: “stop”, “payload”: {“conversation_id”: “2207479a-b15b-4125-8b0c-***”, “generation_id”: “b64669d9-eebf-4421-b15f-***”, “model”: “claude-4.5-sonnet”, “status”: “completed”, “loop_count”: 0, “hook_event_name”: “stop”, “cursor_version”: “2.1.15”, “workspace_roots”:[“/C:/Users/cnd/Downloads/cursor/fusion_ai”], “user_email”: “***”}}
{“timestamp”: “2025-12-02 06:13:29”, “event”: “unknown_event”, “payload”: {“raw”: “test\n”}}

(that last line was me manually running the hook to check it still runs and logs OK - it does).

I log all hooks for auditing - here’s counts of some working ones on my desktop:

$ cat hook_calls.txt | perl -ne ‘$=~s/.cursor_version(…)./cursor_version$1/;print "$" if(/cursor_version/)’ | countp
1188 cursor_version": “2.1.15”,
999 cursor_version": “2.0.77”,
248 cursor_version": “2.1.6”,
81 cursor_version": “2.0.69”,

Here’s some working ones on my laptop:
$ cat hook_calls.txt | perl -ne ‘$=~s/.cursor_version(…)./cursor_version$1/;print "$" if(/cursor_version/)’ | countp
156 cursor_version": “2.1.25”,
26 cursor_version": “2.0.77”,
104 cursor_version": “2.1.6”,

So the last version of cursor I know of that executed hooks properly is 2.1.25

This is my hook file:

$ cat hooks.json 
{
  "version": 1,
  "hooks": {
    "beforeSubmitPrompt": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }
    ],
    "beforeShellExecution": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }
    ],
    "beforeMCPExecution": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }
    ],
    "beforeReadFile": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }
    ],
    "afterAgentResponse": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }
    ],
    "afterFileEdit": [
      {
        "command": "C:\\Users\\cnd\\AppData\\Roaming\\AuraFriday\\mcp-link-server\\bin\\python .\\log_cursor_hook.py"
      }

tested with absolute paths - still no go

Prior to this problem - it used to run the hook, and show the hook output where it now says “no output”

[Chris_Drake]

I also re-tried using “node” instead of python, and also the full path to node as well:

Same problem - your code is not executing the hook at all, and is not reporting any errors about that inside the hook interface either.

I tried a deliberately non-existing hook program:

same as all the others

So that’s the first place your team needs to look: whatever code is trying to run these hooks needs to surface the errors it encounters while doing this, to the “output” area of your “hooks” panel inside “Cursor Settings”.

From there, you’ll be able to track down the bug that stopped hooks being run, and then be able to work on getting their output back into the chat.

IMHO - this is possibly the most important fix you could possibly make to Cursor itself - hooks have absolutely incredible potential to revolutionize cursor’s usefulness.

FYI - I completely restarted Cursor.exe for every test above.

I tried a pile more tests… no luck.

Here’s the log output from the “Hooks” stream:

My code is NEVER being called - this indicates the locaiton of the bug in your code:-

Command: C:\Users\cnd\.cursor\log_cursor_hook.bat (221ms) exit code: 0

your code is not running the hook at all, but seems to think it’s getting an exit code anyhow.

I just updated 2.1.25 to 2.1.44 - still not working.

FYI - this is what they used to look like when they did work in 2.1.25

Hey, could you share the request ID? Private mode should be turned off.

Hi Dean,

Still not working in 2.2.43

You have fixed the prior bug, where it was not calling the hooks at all, but it’s still back to not giving the “agent_message” response from the hook calls back to the model.
