The worst experiences were when I selected a cheap model like Haiku 4.5 and tried to change OpenClaw configurations. Ideally, it's best not to use the agent to set up skills or change settings. I’ve had multiple times where it decided to edit the config file and restarted the gateway, which wouldn’t restart anymore because it hallucinated fields that the OpenClaw gateway doesn’t recognize. This approach only works if you use the frontier models. That also burns credits especially when you start troubleshooting the setup itself.
