# What is verified environment?

A verified environment is one that ran its own declared test command at build time, so it is known to work before an agent is placed inside it.

Verification is a build-time gate, not a runtime check. You declare a verify command with the snapshot, usually the same command your CI runs, and the snapshot is stored only if it exits zero. A failed verification costs nothing.

Without it, a broken environment reaches an episode, the agent fails inside it, and the result is recorded as the agent failing the task. At one episode you would notice. At a thousand you do not.
