Could you build this?
Partial Scaffolding an agent terminal UI is straightforward, but developing a reliable headless PTY daemon with non-blocking multiplexed I/O and accurate VT escape sequence virtualization requires deep systems programming.
What it would actually take: A production implementation requires a systems language such as Rust or Go to manage POSIX pseudo-terminal (PTY) lifecycles, signal handling, and raw ANSI/VT100 escape state machines. The difficult part is guaranteeing robust process isolation, IPC, and reliable async I/O multiplexing when letting autonomous agents inject and intercept shell commands. This requires specialized knowledge in low-level operating system APIs and terminal emulation internals.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
