Could you build this?
Partial Bridging an LLM to an arbitrary interactive pseudo-terminal (PTY) requires managing ANSI escape codes, terminal emulation states, and screen buffer parsing.
What it would actually take: The architecture requires creating virtual pseudo-terminals (pty/termios) in Python or Go, embedding a terminal emulator engine (like pyte or xterm-headless) to parse ANSI escape sequences and render an internal screen state matrix, and feeding text snapshots or coordinate diffs to an LLM. Handling edge cases around interactive curses apps, alternate screens, raw mode, and async input timing requires specialized low-level terminal I/O knowledge.
Discussion
20 comments analyzed.
Competitors mentioned: tmux with agent glue/shims, mcp-repl, agent-tui, Jupyter kernel over MCP, nREPL/CIDER
Concerns raised: Prompt injection vulnerability from TUI output being read as agent context, Token usage impact not clearly documented compared to tmux alternatives, Polling-based interaction model bloats context window, Edge cases with debuggers, multi-line inputs, large outputs, interrupts
Feature requests: Token usage comparison/optimization documentation vs tmux, Support for interactive debuggers (GDB, PDB, delve), Handle large outputs without filling context window, Better support for long-running commands and restarts
