I can't parse this story. "rei" stopped working and you asked "rei" or "clawdbot" to help your troubleshoot? Are you using both? Whos is 'we' in the "we fixed it ourselves" substory?
Clawdbot is the software, they installed their own instance of it and named it "rei". So an instance of Clawdbot named rei helped them to fix a problem in Clawdbot/rei they observed.
Clawdbot allows you to configure your assistant with a name and a persona.
