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

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.
