Jarvis

A multi-agent coding CLI for your terminal. You talk to Atlas, the orchestrator, who delegates to a crew of specialists — Iris (UI/UX), Volt (frontend), Edith (backend), and Friday (QA) — and you watch them work, in parallel, each in their own color.

Jarvis runs on your own Claude Code login (Pro/Max) under the hood — there's no API key to manage and no per-token billing.

See the crew work in parallel

When a task fans out, Atlas delegates to the specialists and they run at the same time — each in their own color, with a live spinner and progress:

Requirements

• Node.js 20+
• Claude Code installed and signed in (claude on your PATH). Check with claude --version and claude auth status. If you're not signed in, Jarvis will prompt you — just type /login.
• (optional) pngpaste for pasting clipboard images: brew install pngpaste

Install

npm install -g jarvis-crew

Use

From inside any project you want to work on:

cd ~/path/to/your-project
jarvis

Jarvis edits files in the current directory. Describe what you want and the crew gets to work.

In the prompt

• ↑ / ↓ — recall previous inputs
• Cmd+V — paste text · drag a file in — attach it by path
• Ctrl+V — paste a clipboard image (needs pngpaste)
• Ctrl+C — interrupt the current run, or quit when idle

Commands

• /login — sign in to Claude Code
• /help — list commands
• /clear — clear the transcript

How it works

Jarvis drives Claude Code headless (claude -p --output-format stream-json) and renders its stream — thinking, tool calls, and per-agent activity — as a live crew UI. The specialists are Claude Code subagents; Atlas coordinates them. Each run is self-contained — it ignores the host project's CLAUDE.md, settings, skills, plugins, and MCP servers, so only the crew and their charters apply.

Model

The whole crew runs on the latest Opus — Anthropic's top model — for the best possible output. It uses the opus alias, so it tracks the newest Opus (4.8 today) automatically, with no code change. Multi-agent runs use more of your Max quota than a single chat — that's the trade for top-tier results. Prefer a lighter model? Set JARVIS_MODEL=sonnet jarvis (or any Claude model alias).

Develop

git clone https://github.com/vaishakh3627/jarvis-crew.git
cd jarvis-crew
npm install
npm run dev     # tsx src/cli.tsx (uses your Claude Code login)
npm test        # vitest
