# Check this computer

> Check saved agents and this computer for setup problems.

Check saved agents and this computer for setup problems.

## Before you start

* Use Node.js `22.22.3` or newer.
* Use an interactive terminal when a command asks for input.

## Check your setup

```bash theme={null}
relaymessenger doctor
relaymessenger doctor --offline
```

The offline option skips the check that calls Relay. Use the full check when you need token and server checks.

## What you get back

Captured with `relaymessenger`. Help output describes the command; it does not prove a live reply.

```text captured-output theme={null}

  "ok": false,
  "checks": [
    {
      "name": "Node.js version",

    },
    {

      "ok": true,
      "detail": "no config file yet, which is fine when the token comes from RELAY_AGENT_TOKEN"

    },

      "ok": true,
      "detail": "skipped, because you passed --offline"
    }
  ]
}

}

## When it fails

Use the [exit-code table](/cli/reference/help#exit-codes) to distinguish input, missing resources, and authentication failures. Follow each reported next step and run Doctor again.
