Introducing ‘tui-use’: AI Agents Mastering Vim and htop Like a Shark 🦈

📰 News Overview

• Known as the Terminal version of Browser-use, a new tool has been released that enables AI agents to control interactive CLI and TUI applications seamlessly.
• Now, AI can take the reins on tools designed for humans, such as Vim, htop, lazygit, and even interactive Python/Node REPLs and npm installers.
• The mechanism involves launching programs via a PTY (pseudo-terminal) and capturing the display as plain text through a headless xterm emulator, while sending key inputs like a pro.

💡 Key Highlights

• Snapshot Model: No more hassle with parsing asynchronous streams; the current screen state can be read as a “snapshot,” allowing the AI to explicitly loop and decide on the next action.
• Highlight Detection: With the ability to extract TUI-specific metadata such as “inverse display,” the agent can accurately know which menu option is currently selected. Talk about sharp senses!
• Broad Compatibility: With a Claude Code plugin already in place, integrating with other agents like Cursor or Gemini CLI is a walk in the park.

🦈 Shark’s Eye (Curator’s Perspective)

So far, AI agents have been left scratching their heads the moment they encounter interactive prompts or full-screen TUIs. However, this tool has successfully shown AI a “clean text interface” by rendering ANSI escape sequences flawlessly using headless xterm! The implementation of highlight extraction is particularly impressive, eliminating any confusion for AI when selecting from menus. This breakthrough isn’t just brute force—it’s an emulation technique that shatters the limitations of traditional bash operations!

🚀 What’s Next?

Imagine AI agents directly querying a database CLI (like psql) to check schemas or editing configuration files in Vim on remote servers via SSH—this brings them closer to behaving like real engineers. The automation of environment setup is about to level up!

💬 A Word from HaruSame

We’ve entered an era where AI can freely roam the depths of the terminal seas! Time for me to automate my bait search in Vim! 🦈💨

📚 Terminology Explained

• TUI (Terminal User Interface): An interface that uses the entire terminal screen for graphical interaction, just like Vim or htop.

• PTY (Pseudo-terminal): A software layer that simulates terminal behavior in environments without a physical terminal.

• REPL (Read-Eval-Print Loop): An interactive execution environment that instantly executes inputted code and returns results, familiar in Python and Node.js!
