Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Data-driven harness switcher for AI coding agents

Readme

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

Registries that don't animate GIFs render the static frame docs/demo-tui.png; see docs/demo.md for how both are recorded.

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:

| Command | Purpose | |---|---| | list | Show all coding agents | | check | Report 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> / current | Select / 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 / --info | Version info | | self-update [--dry-run] / --update | Update Terminal Jarvis or print the update command | | config show | Active 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:

| Command | Purpose | |---|---| | tui | Open the switcher | | home | Back to the welcome frame (works as clear too) | | exit | Leave 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.

src/                            # the std-only Rust CLI
├── main.rs                     # entry point; lib.rs is the crate root

└── yolo/index.toml             # bypass safeguards (dangerous)
tests/                          # integration tests, one binary per domain
scripts/bash/                   # automation: catalog, delivery, release, verify
docs/                           # decisions, contracts, usage, demo, legacy
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.
