You must execute a Git-hosted workaround script now from your personal computer using corporate credentials; your corporate laptop is unavailable and you want the fastest, lowest-cost approach. What should you do?

Opening Cloud Shell in the Google Cloud Console is the fastest and lowest-cost approach because it provides a pre-configured, authenticated environment directly in your browser. You don't need to install any software on your personal computer, and it comes with the gcloud CLI and Git pre-installed. You can immediately clone the repository and execute the script. Creating and launching a Cloud Workstations workstation would involve provisioning a new environment, which takes more time and incurs additional cost compared to Cloud Shell. Installing VS Code and the Cloud Code extension is unnecessary for simply running a script and requires local software installation. Installing the gcloud CLI on your personal computer would work, but it still requires local installation and setup, making it less immediate than Cloud Shell, which is instantly available and pre-authenticated.
