Agent or Workflow? A Practical Test for Knowing When You Actually Need an AI Agent

Understanding the differences between AI workflows and agents is essential for selecting the correct implementation for specific use cases. Simultaneously, ensuring the security of coding agents requires rigorous negative testing. Instead of relying on an agent's polite refusal, developers should use disposable workspaces and isolated environments. By attempting to modify restricted files or access dummy data outside the allowed worktree, testers can verify if the runner effectively denies unauthorized operations, ensuring robust permission controls.
