[Calling tool get_alerts with args {'state': 'CA'}]
Okay, so the user asked about weather alerts in California. I used the get_alerts function with the state code CA. The response came back saying either there's no alerts or they couldn't fetch them. I need to let the user know that.
First, check if there's an error in the response. The isError is false, so it's not an error. That means either no alerts are active or there was an issue fetching. But since isError is false, probably no active alerts.
I should phrase the answer to be helpful. Maybe say "It seems there are no active weather alerts in California at this time." That's clear and positive. Alternatively, mention the possibility of temporary issues, but since the function didn't return an error, better to focus on no alerts.
Make sure to keep the response concise and friendly. The user might be checking for safety or planning something, so assurance is key. Alright, that's the plan.
