GitHub's tui-use tool bridges AI agents to terminal interfaces once limited to humans by enabling programmatic interaction with command-line tools that require human input. Built by onesuper, the tool spawns programs in pseudo-terminals (PTYs), captures screen output as plain text, and allows agents to send keystrokes — mimicking human terminal usage. Its headless xterm emulation ensures ANSI escape sequences, cursor movements, and screen clears render accurately, while a snapshot model simplifies terminal interaction loops by providing clean screen states and highlight metadata.

The tool excels at handling REPL sessions, database CLIs, SSH interactions, and TUI applications like Vim or htop. Highlights capture inverse-video regions to identify active menu options, while rich key support handles Enter, arrow keys, and function keys. Integration with Claude Code and other AI agents demonstrates its utility for scaffolding codebases, querying databases, or operating remote servers interactively.

Installation via npm or GitHub marketplace requires a CLI daemon to manage PTY sessions. While colors/styles are stripped, the tool preserves critical metadata like window titles and fullscreen status. Limitations include Unix-only support (Windows via ConPTY planned) and color loss. Developers can self-host or use prebuilt binaries, with integration tests available for validation.

This innovation expands AI terminal automation capabilities, transforming how agents handle tools never designed for machine interaction. By treating terminals as programmable environments, tui-use unlocks new possibilities for debugging, automation, and AI-driven workflows in developer ecosystems.
