I see, thanks. I was wondering earlier if there would be any practical advantage in creating a custom agent, but couldn't think of any. I guess I simply misunderstood the purpose of your post.
For me, the post is missing an explanation of the reason why I would want to build my own coding agent instead of just using one of the publicly available ones.
As someone using his smartphone as a portable music player every day, I really regret having a smartphone without a headphone jack. Although I agree that using Bluetooth headphones is more comfortable than using wired ones, the loss of sound quality simply is not worth it. Especially the constant static noise in the background while the Bluetooth headphones are active is something I just can not get used to. Unfortunately, it seems that every pair has that issue [1].
