Local multi-agent harness for the terminal coding CLIs you already run — Claude Code, Antigravity (Gemini), OpenAI Codex, OpenCode, Crush, pi.dev, and GitHub Copilot CLI — with bring-your-own keys and local LLMs. Autonomous agents that message, route, and remember — coordinated by a GOD orchestrator you talk to, and visualized as avatars at work on a shared office floor.

[!NOTE] The world's best agents. The world's worst paper company. Munder Difflin takes the terminal-agent CLIs you already run —
claude,agy,codex,opencode,crush,pi, andcopilot— and turns them into a self-coordinating team: each agent gets long-term memory, a mailbox, and a desk on a 2D office floor — and a GOD orchestrator agent routes work between them while you watch.
Munder Difflin is a desktop app that wraps real terminal-agent CLIs as fully-capable agents, wires them into a hive mind, and puts a GOD orchestration agent in charge — the one agent you talk to in order to get things done. Under the hood it runs the fastest memory layer in the world so every agent remembers what it learns and recalls it instantly.
claude, agy, codex, opencode, crush, pi, copilot, or custom session runs as a real
process in a pseudo-terminal (node-pty), byte-for-byte authentic, rendered with xterm.js. you ── talk to ──► ┌─────────────┐

with its own working directory, identity, and provider-specific lifecycle.outbox/; the harness's router delivers into recipients' inbox/. No agent ever touches git

terminal/event plane, and DESIGN.md for the visual system.
| Area | What works today |
|---|---|
| Real terminals | Spawn Claude Code, Antigravity (agy / Gemini), OpenAI Codex, or a custom command in a node-pty PTY. Full read/write/resize/kill, live streaming over IPC, multi-agent. |
| Built-in Monaco IDE (new in v0.3.3) | A title-bar IDE button opens a full-window Monaco editor (the VS Code editor engine, self-hosted — no CDN) over the floor: git CHANGES rail with side-by-side diffs vs HEAD, workspace file tree, editor tabs with dirty-state tracking, Cmd/Ctrl+S save. All fs/git access is brokered through the main process. |
| Multi-provider hive | Claude Code, Antigravity, and Codex workers can all participate in the same hive. Claude uses native hooks; Antigravity gets a native agy-hook bridge; Codex receives the protocol as its initial prompt and participates through inbox/outbox routing. |
| The hive | On-disk multi-agent layer: per-agent identity + long-term memory, atomic-file mailboxes, a shared blackboard, append-only event log, single-committer git. |
| GOD orchestrator | An always-on supervisor agent that adjudicates traffic, routes tasks, scribes the blackboard, and escalates only critical items to you. |
| Memory layer | Markdown-first long-term memory per agent, mined into a shared semantic palace for instant recall; searchable from the UI. Degrades gracefully when the index isn't installed. |
| Office floor | Pixi.js scene with a Tiled office map, camera, recolored cast, pathfinding, seat assignment, and tool-bubble overlays. |
| Message handoffs | When the hive routes a message, an envelope flies from sender to recipient (tinted by speech-act; escalations fly to the door) and pops an arrival sparkle. |
| Per-agent panel | Live terminal, command bar to type back, fullscreen terminal, sandboxed file browser + CodeMirror editor, and a git tab (status, log, commit graph, branches). |
| Approvals & memory panels | Human-in-the-loop approval queue for escalations; a memory search panel over the shared palace. |
| Onboarding wizard | First-run setup: harness home, registered repos, default command, auto-mode. |
| Design system | Fully tokenized SNES / Animal-Crossing aesthetic — pixel panels, buttons, badges, hand-drawn icons. See DESIGN.md. |
| Command Center | Michael's control surface: Terminal, Floor (roster + dispatch + per-agent model selector + live fleet monitoring), Memory (MemPalace + text search + memory graph), Activity (log + board + real token telemetry + observability + CI watcher), Tasks (kanban board with dependencies + status tracking), and a dedicated Schedules tab (recurring missions + adaptive heartbeat). |
| Talk to Michael (Realtime Michael) | A low-latency voice channel to the GOD orchestrator (OpenAI Realtime API over WebRTC), alongside the async terminal. Press Talk and Michael listens, answers, and acts in real time — reads the hive and, behind spoken echo-back confirmation for destructive verbs, creates/assigns tasks, dispatches, spawns/kills workers, and steers the floor (attributed to a distinct michael-voice actor). He greets you on connect, speaks task completions the moment they land ("respond when done"), and runs under a live cost meter with a hard spend cap + idle auto-disconnect. BYOK OpenAI key — decrypted main-only, minted into short-lived ephemeral session tokens, never read back to the renderer. |
| Per-agent git worktrees | 'Git isolation' toggle in Add Agent auto-provisions a dedicated worktree per agent on spawn and tears it down on kill — agents never collide on branches. |
| Token & cost telemetry | Activity tab reads ~/.claude/projects/ JSONL transcripts and surfaces real token counts + estimated USD cost per agent per session, backed by a durable cost ledger that survives restarts. |
| Per-agent token budgets | Set a token budget per agent and watch live fleet monitoring track consumption across the whole roster — paired with the cost/runaway circuit breaker to keep spend in check. |
| Observability | Live OpenTelemetry collector with per-model cost attribution, a fleet grid, and a per-agent tool-span waterfall — see exactly what every agent is doing and what it costs, in real time. |
| Context-window gauge | Each agent card's progress bar is a context-window gauge — see how much of the model's context each agent has consumed at a glance. |
| Circuit breaker | A cost/runaway guard with a steer → constrain → stop ladder: the breaker nudges, then constrains, then stops agents that loop, storm errors, or blow their budget. |
| HITL gate & mid-run control | Human-in-the-loop gate, mid-run steer, and graceful stop — all driven through Claude Code hook returns, so you can intervene without killing the session. |
| Durable persistence | SQLite-backed durable store keeps window bounds + history across restarts, alongside the durable cost ledger and persisted session IDs. |
| MemoryReflector | Memory condensation that summarizes and bounds per-agent memory over time, so long-term memory doesn't grow without limit. |
| Configurable home folder | Point the hive/memory home at any folder, with a safe move that relocates existing state without losing it. |
| Restore team | One-click "Restore team" rebuilds last session's workers after a harness restart — no more re-adding agents by hand. |
| Selectable agent engines | Each agent — and Michael himself — runs on a pluggable engine: Claude Code, Antigravity, OpenAI Codex, OpenCode, Crush, pi.dev, GitHub Copilot CLI (new in v0.3.3 — community-contributed, print-mode copilot -p with model picker and --resume), or a local provider (a claw/qwen backend proxy). Choose the engine per hire from a visual provider/hive picker; the orchestrator's own engine is swappable from onboarding or a change-engine flow. BYOK keys + local-LLM endpoints for the CLI engines live in Settings → AI Engines. |
| BYOK keys + local LLMs | Settings → AI Engines collects per-provider API keys (Anthropic / OpenAI / Google / OpenRouter / Groq) stored write-only in the encrypted secret broker — never read back into the renderer, materialized main-only at spawn — plus per-engine local base-URLs (Ollama / LM Studio / vLLM) and default-model fields. The OpenCode / Crush / pi.dev engines pick these up at spawn. |
| OSS-model quick-picks | Hiring a worker on a local-capable engine (OpenCode / Crush / pi.dev) surfaces curated open-source model quick-picks — a Local bucket (Mac-runnable Ollama tags: gpt-oss 20B/120B, Qwen3, DeepSeek-R1, Mistral Small, Llama 3.3 70B …) and a third-party OSS provider bucket (BYOK via Groq / OpenRouter) — that fill the engine-correct slug (local/<tag> for OpenCode, ollama/<tag> for Crush/pi) and rebuild the spawn command. Two how-to guides — run on open models and run on a Mac Mini — are linked inline. |
| Provider-agnostic idle backstop | A PTY-quiescence fallback flips any silent-but-pinned-working agent back to idle, so the idle inbox-wake nudge always drains a non-Claude orchestrator even if a bridge's turn-end signal (Stop / session.idle / agent_end) never fires — the safety net under shipping every new engine as god-eligible. |
| Self-healing engine install | When a chosen engine's CLI binary is missing, the harness runs its installer in the terminal, then auto restart-and-continues into the freshly-installed binary in place — no dead-end, no manual click, idempotent so the installer never fires twice. |
| Per-hire skills + MCP catalog | Every hire carries a manifest of allowed skills + MCP servers (default-deny over a shared catalog). Bundled skills ship with the app, and a consent UI surfaces every skill/MCP a hi |
