Description

opencode doesn't buffer input while it starts up. You stare at a blank terminal for several seconds (especially on Windows with lots of plugins), and by the time the UI comes up you've forgotten what you were going to type. Other tools like Pi let you start typing your prompt while the UI is still loading.

--prompt exists but doesn't support multiline input. The expectation is that you can just start typing immediately after running opencode and have everything appear in the prompt once it's ready.
