Description

When using the Agent Mode in Copilot Edit, the terminal hangs indefinitely with the message:
Running command in terminal….

This issue occurs while the agent is attempting to execute terminal commands. The process does not complete, and no further output is provided in the terminal.

Steps to Reproduce

1. Open Visual Studio Code with the Copilot extension installed.
2. Enable Agent Mode in Copilot Edit.
3. Trigger a task that requires the agent to run a command in the terminal.
4. Observe the terminal output.

Expected Behavior

The terminal should execute the command and provide the expected output or error message.

Actual Behavior

The terminal hangs with the message:
Running command in terminal…
No further progress is made, and the process does not complete.

Me too, same logs. I'm using:

• Windows 11
• WSL Ubuntu
• Terminal ZSH
• VSCode 1.98.0-insider
• GitHub Copilot Chat Version: 0.25.2025021301

Update: I tested it with bash instead of zsh and it worked

[Tyriar]

These types of problems are likely due to lack of shell integration, notice that you don't have circles on the left of the terminal like this:

This is probably the reason bash works fine. Note also there are known issues with powerlevel10k as well since they disable our shell integration explicitly in favor of ours (which we should handle gracefully).

[argentinaluiz]

@Tyriar Thanks for you support Daniel!

I have updated the powerlevel10k, the latest version improves the vscode integration and copilot in agent mode works.

[Tyriar]

@argentinaluiz great to hear!

[kennyeni]

Can we get the workaround instructions? I'm also using powerlevel10k

Thanks!

[argentinaluiz]

@kennyeni Follow the update command for oh-my-zsh in readme: https://github.com/romkatv/powerlevel10k?tab=readme-ov-file#how-do-i-update-powerlevel10k.

Then, restart the terminal

[ShaiDiamant]

I have encountered a similar issue using zsh with oh-my-zsh but no powerlevel10k.
I do have zsh-autosuggestions though, maybe related?

Would appreciate any thoughts on how to fix.

I did try verifying the $ZDOTHOME value, the bin executable path and all of those.

[Tyriar]

@ShaiDiamant do you have a right prompt? I've seen that mess with our shell integration too.

[ShaiDiamant]

@ShaiDiamant do you have a right prompt? I've seen that mess with our shell integration too.

I didn't change the prompt and I only recently downloaded the VS Code Insiders, so I assume I should have the right prompt..

Also - it does trigger terminal commands, but kind of waits forever even after they finished running

Edit:
I now think I got the issue figured out - I have some setup commands running when I open a new zsh terminal (to activate pyenv) - so it takes around 1 second to set it up, and I think it executes the command in parallel.
as mentioned above - there is no circle on the left next to the first executed command, but if I just submit another command and then try to execute another command, it suddenly does have the left circle, and works.

I guess there's some sort of delay with the integration availability.
In the image below you can see the flow:

1. Asked it to execute a test command
2. It executed, the result was printed, but no left circle
3. I pressed "Return" to input an empty value - it thought this is the response to the original command
4. I asked it to try again, it did, and this time it saw the response successfully

Also, I noticed that if the agent tries to execute a command in the terminal, then I kill it, then the same chat tries to execute another command - it also hangs (I think it is waiting for response from the original terminal, but it no longer exists)

Edit 2:
I was using Agnoster theme, with pyenv + nvm which slowed my zsh startup time significantly.
I switched to powerlevel10k with insta prompt enabled and it resolved the issue - even while still having pyenv + nvm that still slow the startup time.

Hi! I have a similar issue. I am using Powershell 7.5 and I have the terminal integration enabled, without decorations. It works for scripts that have an end, but seems like It can not read the output of the terminal while the script is running. I am not sure if this an issue but would be very useful if the copilot could read the output, stop the terminal if it sees errors, fix them and then run again.

[Tyriar]

The updates may be bringing in romkatv/powerlevel10k@119e403 which forces p10k's shell integration to be enabled.

[Tyriar]

The remaining fix here is going to be adding a section about updating p10k to the terminal shell integration and copilot docs: microsoft/vscode-docs#8082

@Tyriar Please note that this is not exclusive to p10k - it also happened to me before I started using p10k. p10k actually resolved this for me.

[Tyriar]

@ShaiDiamant thanks, will try out using your setup too (oh-my-zsh/zsh-autosuggestions/pyenv/nvm)

[ShaiDiamant]

@Tyriar I think the actual causes were pyenv + nvm which significantly slowed the load of the terminal due to these commands in the ~/.zshrc:

export NVM_DIR="$HOME/.nvm"
 [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
 [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init - zsh)"
