Is it possible to add commands and a custom UI using plugins?

[aris-2]

Question

As stated in the title, I would like to modify OpenCode to interact with some IoT devices that require authentication, but I don’t want to provide credentials in plain text.

The idea is to create a plugin that retrieves credentials from a database; however, I haven’t been able to find a good way to create a UI to store those credentials in the database.

I would like everything to be fully integrated directly into the OpenCode terminal, without relying on external interface
