Copilot chewing through premium request

[hiaw]

I thought I'd try opencode with copilot. It worked great without any setup. However, I noticed that it'd gone through dozens of premium request even though it was only a few chat interactions. I think the way copilot premium request work is that it's only 1 request per user prompt. So I think when the LLM agent comes back with a tool call, it's sending that as a user prompt as well. Therefore chewing through the premium requests I have available.

Now I just go back to codecompanion in Neovim and VS code and it works as expected there.
