In my case it has its own Docker container it can do as it pleases in, is more usable from a smartphone on the go, and has tooling geared toward long-lived loops, including automatic session resumption after power loss.
Kanban boards, in-system cron tasks, automatic skill creation and improvement, automatic context compression, and more.
Herems is better suited as an independent agent in my opinion, and I still see OpenCode as primarily an interactive one. Sure, you can hammer OpenCode into an independent agent I'm sure, but I'd rather use a system someone else has put more hours of thought and design into.
