Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

When running cursor-agent in a GitHub Action the agent successfully completes performs the instructions requested in the prompt, but then hangs indefinitely.

Important: the very same command run in a local shell terminates sucessfully.

Steps to Reproduce

Run the following GitHub Action:

name: Cursor Code Review

on:
  workflow_dispatch:
  pull_request:
    types: [opened, synchronize, reopened, ready_for_review]

jobs:
  code-review:
    runs-on: ubuntu-latest
    timeout-minutes: 5
   
    steps:
    - name: Checkout repository
      uses: actions/checkout@v4

    - name: Install Cursor CLI
      run: |
        curl https://cursor.com/install -fsS | bash
        echo "$HOME/.local/bin" >> $GITHUB_PATH
        cursor-agent --version

    - name: Perform code review
      env:
        CURSOR_API_KEY: ${{ secrets.CURSOR_API_KEY }}
        MODEL: auto
      run: |
        cursor-agent \
            --force \
            --model="$MODEL" \
            --output-format=text \
            --print \
            "Say hello"

Expected Behavior

I’d expect cursor-agent in the headless mode to exit after processing the prompt.

I’m experiencing the same problem. Cursor CLI works fine locally, but indefinitely hangs jobs in GitHub Actions. In the meantime we’ll explore Aider & Claude Code for our CI/CD AI needs.

I also have exactly the same issue, when i copied this example:

Model responds corectly that it done everything, but the job on github actions stuck

I wrote simple sh script via cursor

it’s parsing JSON output and stopping cursor-agent if see result in output. That can be used as workaround now.
