I guess it was breaking before and it still breaks

it does work fine with;
echo 'Hi' | opencode runthe easy fix would probably be to add this error log;
Cannot run TUI with piped input. Use 'opencode run' instead: echo 'Hi' | opencode runrichard-hajek commentedon Nov 4, 2025

tldr:
if user wants to maintain TUI but also pipe in some data, app must open /dev/tty and read from that

@kunaljaykam Sorry I started working on this before I saw your comment. I think I saved you a bit of headache tho.
