Changes to the tools coding agents drive, since a model's training cutoff, each linked to its first-party source. Check installed versions and limitations before acting; a cutoff date does not establish what a model knows.

```
k3d cluster restart <cluster-name>
```

```
k3d cluster restart
```

```
k3d cluster restart --all
```

Defaults to `k3s-default` when omitted."; "--all, -a: Restart all existing clusters."; "--wait: Wait for servers and load balancer to be ready before returning; defaults to true."; "--timeout: Maximum wait time before canceling or returning; defaults to 0 seconds."; "Docs conflict: The v5.9.0 command reference lists cluster start and stop but omits restart; the v5.9.0 command implementation defines `cluster restart`."
