Terminal Jarvis

Command center for orchestrating context switching between coding-agent harnesses

Safe Testing Recommended: Terminal Jarvis is a harness for AI coding tools that can modify files and execute commands. For the safest experience, test in a remote development environment such as GitHub Codespaces, Coder, DevPod, or Google Colab.

NPM Version Crates.io Homebrew License: MIT Mentioned in Awesome Docs Coverage

Install

Package mechanics, supported platforms, and update behavior: Installation.

# Cargo
cargo install terminal-jarvis
# Cargo binary name is terminal-jarvis; add an alias if you want a short call:
#   echo 'alias tj=terminal-jarvis' >> ~/.bashrc

# npm
npm install -g terminal-jarvis
# The npm package also installs a tj shim, so you can call either:
#   terminal-jarvis list   # or  tj list

# Homebrew
brew install BA-CalderonMorales/homebrew-terminal-jarvis/terminal-jarvis

Quick Start

Inspect and safely gate catalog descriptors for Claude, Gemini, Qwen, Pi, Droid and a variety of other AI assistants from one terminal interface. The modes, the launch guards, and the full command surface: Usage.

# Open the interactive switcher (bare tj on a terminal does the same)
terminal-jarvis tui

# List every coding agent
terminal-jarvis list

# Inspect a harness
terminal-jarvis show opencode

# Preview a capability command
terminal-jarvis plan codex headless

# Select and verify the active harness
terminal-jarvis use opencode
terminal-jarvis current
terminal-jarvis check

# Optional: block harness commands until Trivy clears this workspace
terminal-jarvis gate enable trivy
terminal-jarvis gate status

Commands

Commands run in one of two ways: headless (terminal-jarvis <command>) or inside the interactive switcher (terminal-jarvis tui), and every command is the same however you reached the tool:

  • Installed globally (npm, Homebrew, or Cargo): terminal-jarvis list / tj list
  • No install -- run on demand from anywhere: npx terminal-jarvis list
  • Built from source (this repository): cargo run -- list

First time here? No install needed -- npx terminal-jarvis tui opens the switcher directly.

Headless (terminal-jarvis <command> / tj <command>) -- one command per invocation, for scripts, CI, and one-shot tasks:

CommandPurpose
listShow all coding agents
checkReport binary + env readiness
show <harness>Inspect a harness's capabilities
install <harness>Install a harness
update [<harness>]Upgrade a harness
plan [harness] <capability>Preview the shell command
use <harness> / currentSelect / show active harness
run [harness] [capability] [args...]Execute a capability
security [status|audit|<harness>]Security posture
gate [status|list|enable|disable|run]Optional local security gate
version [--verbose] / --version / -v / --infoVersion info
self-update [--dry-run] / --updateUpdate Terminal Jarvis or print the update command
config showActive config state
auth help <harness>Credential setup guidance
[harness] [args...]Pass-through to harness binary

Interactive (terminal-jarvis tui / bare tj on a terminal) -- the chat-style switcher with the numbered picker and readiness dashboard. Every headless command above also works here, plus:

CommandPurpose
tuiOpen the switcher
homeBack to the welcome frame (works as clear too)
exitLeave the switcher

Layout

The repository is a few small planes, and every Rust domain is bucketed the same way -- once you can read one, you can read them all.

build/                          # the build script only
npm/  homebrew/                 # distribution launchers and formulae

Each Rust domain inside src/ keeps the same shape: index.rs as the public face, logic/ for behavior, structs/ for data, tests/ for proof, and every file stays at 100 lines or fewer.
