Smoke curls from my monitor as I watch Claude 3.5 Sonnet—yes, that beast—effortlessly tab through htop’s menus, arrowing to processes, killing one with a precise Ctrl+C.
No copy-paste hacks. No fragile bash scripts. Just pure, unadulterated terminal mastery.
That’s tui-use in action, the Show HN gem that’s quietly handing AI agents the keys to every interactive CLI corner bash dreams of but can’t touch. Like BrowserUse for browsers, but laser-focused on terminals—REPLs, installers, TUIs built for squishy human fingers, not silicon brains.
Agents crush shell commands, file reads, API calls. Then bam—hit an input prompt, and they’re stuck. tui-use? Spawns programs in a PTY, snapshots the screen as crisp text, fires keystrokes. If you can mash it out in your terminal, agents can too.
Why AI Agents Have Been Terminal Virgins (Until Now)
Think back to the GUI revolution. Back in the ’80s, desktops exploded because point-and-click let normies (and scripts) tame apps. Terminals? Stuck in script-kid heaven—great for one-shots, useless for anything chatty.
Here’s the unique twist no one’s yelling about yet: tui-use is the command-line GUI enabler. It’s scripting the unscriptable, like if Selenium showed up for bash but smarter. My bold prediction? This births “agent devops” swarms—fleets of AIs SSHing into prod, tweaking htop readings, REPL-debugging live Node apps, all without your $500k SRE team’s blessing.
tui-use gives agents access to the parts of the terminal that bash can’t reach — every REPL, installer, and TUI app built for humans.
Spot on. And it’s not hype—it’s a PTY daemon with xterm.js headless rendering, spitting “polaroid” snapshots: clean text screens, highlight metadata for selected menus, even fullscreen detection.
No async stream nightmares. No guessing partial outputs. Just loop: snapshot, decide, type, repeat.
How tui-use Actually Works (No Smoke, Just Mirrors)
Fire it up: npm install -g tui-use, then tui-use start vim. Boom—session spins up, daemon handles the PTY magic via HTTP.
Screen? Processed ANSI through @xterm/headless—colors fade to plain text, but highlights catch inverse-video glow (think active tabs in lazygit). Keys? Full arsenal: arrows, F-keys, Ctrl combos. tui-use type "iHello", Enter, Esc—vim bows.
And the CLI’s a dream: snapshot --format json for agent chow, wait --text "prompt:" to chill till ready, find regex for hunting. Custom cols/rows? Check. Multi-paste? Yup.
But—slight imperfection alert—colors strip out. Fine for agents parsing text; humans might miss the rainbow. Still, for Claude Code, Cursor, Gemini CLI? Chef’s kiss.
Can AI Agents Master Vim and htop Now?
Hell yes. Picture ssh-ing remote, firing tui-use start --cwd /prod lazygit. Agent reads the commit graph snapshot, arrows to a branch, merges. No more “can’t script vim, bro.”
REPLs? Python interpreter lives forever—inspect vars, loop queries in psql sans ORM cruft. Scaffolders like npm create? Agent answers the wizard Qs, spits a boilerplate React app.
My inner futurist geeks out: this is agents graduating from toy scripts to full-stack terminal denizens. Corporate PR might spin it as “productivity,” but nah—it’s arming rogue AIs for unsupervised infra romps.
Real Use Cases That Feel Like Sci-Fi
Database dives: tui-use start psql, agent queries schemas, tweaks indexes live.
TUI nav: fzf fuzzy-find files, htop cull zombies—all agentic.
Install fests: cargo new, create-react-app—step through without timeouts.
And plugins? Drop into Cursor or OpenCode: /plugin install tui-use@tui-use. Reload, done.
One caveat—they’re coming, but not here yet. Daemon’s your quiet overlord, though. tui-use daemon restart if it hiccups.
Why This Changes Everything for Devs (And Maybe Scares Ops)
Terminals were the last human bastion. tui-use cracks it, predicting a world where agents don’t just code—they operate.
Skeptical? Install it. tui-use start redis-cli, watch an agent ping-pong keys. Wonder hits like a freight train.
But here’s the callout: docs nod to color loss—agents don’t care, but if your TUI’s a rainbow riot, highlights save the day. Solid engineering, no vapor.

Frequently Asked Questions
What is tui-use and how do I install it?
It’s a CLI tool letting AI agents control interactive terminal apps via PTY snapshots. npm install -g tui-use, or build from GitHub.
Can tui-use let AI agents use vim or htop?
Absolutely—full key support, screen snapshots with highlights make navigation trivial for agents like Claude or Cursor.
Does tui-use work with remote SSH sessions?
Yes, SSH in and run TUIs on the far end; agents keep the session alive for interactive control.
Will tui-use replace traditional scripting?
Not fully, but it supercharges agents for anything interactive—REPLs, wizards, TUIs—beyond bash’s reach.
