364364### Verification loop
365365
366How a session knows the work is actually done rather than just plausible. You give Claude a check it can run, such as a test suite, a build, or a screenshot comparison, and Claude iterates until the check passes instead of stopping after one attempt. A verification loop is the prerequisite for [`/goal`](/docs/en/goal), unattended runs, and [dynamic workflows](/docs/en/workflows): without one, the only thing deciding the agent is finished is the agent itself.
