It’s an assistant, answering your question and running some errands for you. If you give it blind permission to do a task, then you’re not worrying about what it does.
That's not what they're doing, they are trying to use plan mode to plan out a task. I don't know where you could have got the idea that they were blindly doing anything.
The plan mode uses sub tasks to read, find, list, or grow out certain information. I would imagine those tasks would be covered by the dubiously discovered a/b testing
