I like how I can cycle through agents in OpenCode using tab. In CC all my messages get interpreted by the "main" agent; so summoning a specific agent still wastes main agent's tokens. In OpenCode, I can tab and suddenly I'm talking to a different agent; no more "main agent" bs.
I thought of that! but CC is so clunky and slow that it doesn't make sense to do this. with codex cli tho, that's a totally different story cause it's written in Rust.
