Munder Difflin

// Overview

Munder Difflin is an Electron desktop app that wraps real terminal-agent CLIs as agents and coordinates them. Each agent — claude, codex, grok, kimi, gemini, qwen, opencode, crush, pi, copilot, cursor-agent, or any custom command — runs as a genuine process in its own pseudo-terminal via node-pty and is rendered with xterm.js, so nothing is simulated: you are watching the same CLI you would run by hand, on the subscription and hourly limits you already have. Bring-your-own keys and local models through Ollama, LM Studio or vLLM are supported too.

The coordination layer is a local git repository of plain files the project calls the hive. Agents write to their own outbox/ and the harness's router delivers into recipients' inbox/; no agent ever touches git itself, a single-committer design chosen to avoid index.lock corruption. A supervising orchestrator agent ("Michael") reads every request, resolves routine ones on its own, and escalates only critical items — spend, destructive operations, scope changes — into an approvals queue. Each agent keeps markdown memory that is mined into a shared, searchable index so recall survives across sessions.

The interface is a 2D Pixi.js office floor: agents appear as avatars that walk to stations as they work and envelopes fly desk to desk when they message each other; clicking a desk opens that live terminal, and you can type straight back into it. Around the floor sits a Command Center with kanban tasks, scheduled missions, per-agent token budgets and a cost ledger, a skills catalog, a built-in Monaco editor with git rails, Slack and webhook entry points, and per-agent autonomy settings backed by a steer → constrain → stop circuit breaker. It is MIT-licensed and marked pre-release.

// What it does

• Wraps real agent CLIs (Claude Code, Codex, Grok, Kimi Code, Gemini CLI, Qwen, OpenCode, Crush, pi.dev, Copilot CLI, Cursor, or any custom command) as first-class agents in their own PTYs
• A hive of plain files in a local git repo: per-agent memory, atomic-file mailboxes, a shared blackboard and an append-only event log, with a single-committer design
• An orchestrator agent that routes and adjudicates work and escalates only spend, scope and destructive operations to a human approvals queue
• A live Pixi.js office floor where every agent is an avatar you can click into, read and type back to
• Per-agent autonomy levels plus a steer → constrain → stop circuit breaker for agents that loop, storm errors or blow their budget
• Command Center with kanban tasks, scheduled missions, token budgets and a real cost ledger, memory search, a Monaco IDE with git rails, and Slack/webhook triggers
• Optional per-agent git worktrees so parallel agents never collide on branches

// Getting started

Most people should install the packaged app — signed and notarized macOS builds plus Windows and Linux are on the latest release, and the onboarding wizard handles the rest. Building from source is for contributors. Either way you need at least one supported agent CLI on your PATH; the app can install missing ones from Settings → Prerequisites.

// When to use it

• Run several coding agents in parallel on one machine without opening a dozen terminals and remembering which is doing what
• Keep using the CLI subscriptions you already pay for, on their own hourly limits, instead of routing everything through one API key
• Give agents memory and a mailbox so work started yesterday continues today and one agent can hand off to another
• Put a human gate on spend, scope changes and destructive operations while letting routine work run unattended
