Describe the bug

Typing @buffer or any other context placeholder into the opencode window doesn't send the related context to the model. Placeholder are sent as they are to the model.

Configuration:

vim.g.opencode_opts = {
  port = 5999,
}

Steps To Reproduce

1. Toggle opencode terminal
2. Type, for example, @buffer
3. Send the message

Expected Behavior

opencode.nvim should insert the requested context into the message

It's not supposed to replace contexts typed directly into opencode. Only when using the plugin's API, like ask or prompt.

I suspect this would be impossible. Unless maybe we inject an opencode plugin that processes the prompt before submission? Idk how the TS <-> Lua communication would work though.

I'm sorry, I might have misremembered how this should work. From my recollection, I used to be able to get autocomplete for things like @buffer inside the opencode terminal.
I also thought this was the way it was supposed to work because when trying the plugin ask api, opencode still has to go through the read tool call to retrieve the context.

opencode still has to go through the read tool call to retrieve the context.

Yeah, unfortunately with the migration to opentui, opencode does not insert the file content when file references are appended to the TUI input anymore. As opposed to when typing directly in the TUI and you select a file from the @ list. I hope they add it back soon because it's certainly a better experience. I think there's an open PR somewhere.
