Example

Before:

agent Bot{
role "helper"
model "claude-haiku"
state{count:int=0}
every 1.day{notify user "hello"
self.count=self.count+1}}

After keel fmt:

agent Bot {
  role "helper"

  model "claude-haiku"

  state {
    count: int = 0
  }

  every 1.days {
    notify user "hello"
    self.count = self.count + 1
  }
}
