What It Does

Many powerful CLI tools require human interaction - vim waits for keystrokes, git rebase -i opens an editor, apt asks for confirmation, TUI applications respond to keyboard input. These tools can't be automated with simple shell scripts because they:

  • Open full-screen interfaces
  • Wait for user input
  • Show dynamic menus and prompts
  • Require terminal emulation

interminai solves this by wrapping any interactive program in a pseudo-terminal (PTY), capturing its screen output as text, and providing a simple API to send input and read the display. This allows AI agents, scripts, or automated systems to interact with vim, git, debuggers, configuration wizards, and any other interactive terminal application.

Core Capabilities

  • Screen capture: Read the current terminal display as ASCII text
  • Input control: Send keystrokes, commands, and control sequences
  • Process management: Start, monitor, signal, and stop wrapped processes
  • Daemon mode: Run in background for long-lived interactive sessions
  • Terminal emulation: Basic PTY with ANSI escape sequence handling

Use Cases

  • AI agents editing files with vim
  • Automated git operations (git rebase -i, git add -i, git commit)
  • Interactive package management (apt, yum)
  • Debugging with gdb or lldb
  • Configuration wizards (rclone, raspi-config)
  • TUI applications (htop, tmux, screen)
  • Any CLI tool that requires keyboard interaction

Installation

Quick Install

npx skills add mstsirkin/interminai

Works with Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, and other skills-compatible agents. Tested on Linux but should work on any Unix-like OS (Linux, macOS, or Windows Subsystem for Linux).

Manual Install

interminai is available in two implementations with identical functionality:

  • Rust (recommended) - Fast, zero dependencies, single binary
  • Python - Easier to modify, requires Python 3.6+

Choose the one that best fits your needs.

Option 1: Rust Implementation (Recommended)

Prerequisites:

  • Rust toolchain (rustc 1.70+, cargo)
  • Linux or macOS (requires PTY support)

Build from source:

# Clone the repository
git clone <repository-url>
cd rust

# Build release binary
cargo build --release

# Binary will be at: target/release/interminai

# Check available commands
./target/release/interminai --help

Install as Agent Skill:

# Build and install Rust version
make install-skill-rust

# Or just:
make install-skill

# The binary is installed to: skills/interminai/scripts/interminai
# (accessible via .claude/skills and .codex/skills symlinks)

Option 2: Python Implementation

Prerequisites:

  • Python 3.6+
  • Linux or macOS (requires PTY support)

Install as Agent Skill:

# Install Python version
make install-skill-python

# The script is installed to: skills/interminai/scripts/interminai
# (accessible via .claude/skills and .codex/skills symlinks)

The Python implementation (interminai.py) is ready to use without compilation.

# Check available commands
./interminai.py --help

Quick Start

# Start vim editing a file
interminai start --socket /tmp/vim.sock -- vim myfile.txt

# Send keystrokes (enter insert mode, type text, escape, save)
interminai input --socket /tmp/vim.sock --text "iHello, World!\e:wq\n"

# View the screen
interminai output --socket /tmp/vim.sock

# Stop the daemon
interminai stop --socket /tmp/vim.sock

Documentation

  • examples.md - Detailed usage examples (vim, git, debugging)
  • reference.md - Complete command reference
  • PROTOCOL.md - Socket communication protocol specification

Verification

Commands

# Start an interactive program (runs as daemon by default)
interminai start [--socket PATH] [--size WxH] [--no-daemon] -- COMMAND...

# Send input
interminai input --socket PATH --text TEXT

# Get screen output
interminai output --socket PATH

# Check if running
interminai running --socket PATH

# Wait for process exit
interminai wait --socket PATH

# Send signal
interminai kill --socket PATH --signal SIGNAL

# Stop daemon
interminai stop --socket PATH
