Grok Bot Auto-review blocks local commands: “executable content could not be bound to this review”

Where does the bug appear (feature/product)?

Grok Bot

Describe the Bug

Grok Bot local command execution is consistently failing in the Auto-review layer with the following error:

“executable content could not be bound to this review”

The local execution permission prompt appears normally, but after I approve the command, Grok Bot does not actually launch it.

This is not limited to my own scripts. Even a trivial system Python command fails with the same Auto-review error:

/usr/bin/python3 -c “print(‘exec-ok’)”

The exact same command works normally when executed manually from the Linux terminal.

I have also reproduced the issue with:

  • a small shell wrapper
  • a Python helper script
  • direct Python execution

All of those commands work normally outside Grok Bot but fail when Grok Bot attempts to execute them.

This appears to be a failure in Grok Bot’s local-execution / Auto-review layer before the requested process is launched.

Steps to Reproduce

  1. Run Grok Bot on a Linux environment with local computer execution enabled.

  2. Ask Grok Bot to execute this simple local command:

    /usr/bin/python3 -c “print(‘exec-ok’)”

  3. Grok Bot displays the local execution permission prompt.

  4. Select “Allow once” to approve the command.

  5. Instead of executing Python and returning “exec-ok”, Grok Bot reports:

    “executable content could not be bound to this review”

  6. Retrying approval does not produce a usable approval card and the command still does not execute.

  7. Run the exact same command manually from the Linux terminal:

    /usr/bin/python3 -c “print(‘exec-ok’)”

  8. The command executes normally and prints:

    exec-ok

I can also reproduce the same Grok Bot failure using a local shell wrapper and a local Python script, both of which execute successfully when run manually.

Expected Behavior

After I approve local execution, Grok Bot should execute the approved command and return its output.

For the minimal reproduction command:

/usr/bin/python3 -c “print(‘exec-ok’)”

the expected output is:

exec-ok

Operating System

Linux

Version Information

Grok Bot 0.43.0 (Linux amd64)

N/A — this appears to be a local execution / Auto-review tooling failure rather than a model-response issue.

Additional Information

Environment:

  • Grok Bot Linux desktop app
  • Running inside the ChromeOS Linux/Penguin environment
  • x86_64
  • Local computer execution is enabled

Additional observations:

  • Grok Bot can see/list the local files involved.
  • The normal “Allow Grok Bot and all Bots to run commands on your local computer?” prompt appears.
  • Selecting “Allow once” does not resolve the problem.
  • Approval retry does not surface a usable additional approval card.
  • The failure occurs before the process appears to launch.
  • The same commands work when executed manually from the same Linux environment.
  • The issue reproduces even with /usr/bin/python3 and a simple print command, so it does not appear specific to a custom script, shell wrapper, SSH, application code, or file permissions.

There are other public reports of the same error:

“executable content could not be bound to this review”

I am adding my reproduction because it occurs with Grok Bot local execution on ChromeOS Linux/Penguin and can be reproduced with a minimal system Python command.

Hey @Jojo1, thanks for the detailed report and the minimal repro. That really helps.

This is a known issue we’re tracking, and I’ve attached your case to it. It’s not related to your scripts or ChromeOS. Before running a command on your computer, Grok Bot tries to read the program it’s about to run so it can show what will happen. When that program is a compiled binary (like /usr/bin/python3), or when the first argument is a flag like -c, that read fails, and the command gets rejected before the approval card even appears. So “Allow once” won’t help here.

Until this is fixed, these two formats already work:

  1. Send the code to the interpreter via a pipe instead of -c or a full path:
    echo "print('exec-ok')" | python3
  2. Put the code into a small text file in your home folder and run it with just the interpreter name:
    python3 exec_ok.py

For now, avoid full paths to programs (/usr/bin/python3, /bin/echo), python3 -c, bash -c, python3 - with heredoc, and also ~/ inside a path that’s passed to python3 or bash.

Can you ask the Bot to run option 1 and tell me if it prints exec-ok? That’ll confirm you’re hitting this exact issue and that the workaround works on your setup. I can’t share an ETA yet, but I’ll reply in the thread if there’s an update.

Thanks, Dean — option 1 works on my setup.

I tested:

echo “print(‘exec-ok’)” | python3

and Grok Bot successfully returned exec-ok with exit 0.

I then adapted the same pipe approach to my actual helper. That also
worked end-to-end on ChromeOS Linux/Penguin:

  • Grok Bot invoked the helper through the pipe workaround
  • the helper reached the remote backend
  • I created a real test reminder
  • queried the live reminder list and got it back
  • deleted the reminder successfully

So this workaround is enough to make my Grok Bot workflow operational for now.

One useful data point: option 2 did NOT work for my real helper. I set
the working directory explicitly and ran:

python3 viviana_grok_reminders.py reminders list

and Grok Bot still returned:

“executable content could not be bound to this review”

So on my setup:

  • echo "...python source..." | python3 = works
  • python3 script.py with an explicit working directory = still bind-fails

Thanks again for the quick response and for attaching my case to the
tracked issue. Happy to test anything else that would help.

Great to hear the pipe version got the whole workflow working. Creating, reading, and deleting the reminder all went through. Thanks for testing both options and writing up such a detailed report.

Your note about option 2 is helpful. Even with python3 script.py and an explicitly set working directory, you still hit the same bind reject. That matches the same underlying behavior. The error hint about an explicit working directory doesn’t help in these cases. I shared this as an extra data point Linux or ChromeOS plus your scenario alongside what we’re already tracking.

For now, please stick with the pipe approach, like echo "...source..." | python3, since it also works for the real helper. I can’t share an ETA yet, but if there’s an update, I’ll reply in the thread. If you run into any other command shape that behaves oddly, send it over. It’s always useful.
