Terminal sometimes doesn't wait for command to finish

Bug Reports

Describe the Bug

When the agent runs terminal commands, it sometimes thinks there was no output when in reality the command hadn’t finished. So then it tries again, and reads the previous terminal output and then sees the output. But the command is running again. So this causes issues and uses a couple more tool calls than necessary.

Steps to Reproduce

It runs RSpec commands, and sometimes it’ll still be running and then the agent will write:

The last command gave no output. I’ll rerun it with verbose RSpec formatting to see what’s happening with the tests.

Expected Behavior

Runs only once and waits for command to finish.

Additional Information

It’s been happening to me since around 0.50?
I’ve tried closing terminals, etc. in case it’s some terminal state thing.
Maybe it happens more when scrolling up to see terminal output, or on the first terminal command of new chats?

Does this stop you from using Cursor

No - Cursor works, but with this issue

I have found what seems to be a minimal repro case:

  1. Start a new agent chat. Pick any reasonable model. claude-3.5-haiku seems to work fine. (btw, this one doesn’t show any request cost info on hover)
  2. Ask “show me the contents of the last git commit in patch form”
  3. The terminal output usually looks fine. And then it’s like the model can’t see it.

Here is a specific export:

# Show last git commit contents

show me the contents of the last git commit

I'll help you retrieve the contents of the last git commit. I'll use the terminal command to show the details of the most recent commit.

(note: this is where the terminal output is, but not shown in export)

I apologize, but it seems the command didn't produce any output. Let me try an alternative approach to show the last commit details:

(note: it retries in the background and replies before the command finishes, so you get duplicate output)

Let me break down the last commit for you:

Other notes:

  • I am using ZSH as terminal. Not using oh-my-zsh or anything like that.
  • This seems to happen for the first terminal command almost all of the time.
