Munder Difflin v0.2.6

A local hive of Claude Code, Antigravity & Codex agents that run themselves — messaging,
routing, and remembering, coordinated by a GOD orchestrator you talk to. Local-first and open source.

What's new in 0.2.6 — Polish & reliability

A focused patch that fixes the first thing you see and the first thing that can break:

  • The agent terminal renders correctly the moment it opens. It used to fit before its
    pane had a real size — and cache the character-cell metrics from before the VT323 font
    loaded — so the welcome banner came up oversized and clipped until you manually resized.
    The view now waits for a real size, re-measures and re-rasters once the font is ready, and
    lets a ResizeObserver drive the first fit. It just fits.
  • npm run dev no longer crashes on a fresh clone (#67). The boot-time Slack-trigger
    .cjs sidecar is now copied by a vite writeBundle plugin, so both dev and build
    emit it from one place (the packaged-build fix in v0.2.5 didn't cover the dev path).
  • Windows: node-pty ConPTY crash guarded (#65). The main process no longer dies when
    ConPTY fails to attach a console — a companion hardening to the Antigravity provider work.
  • The wall clock is interactive (#64). The office clock shows the real time, and clicking
    it opens the closing-time (graceful shutdown) flow.
  • ASK ME reads in the memory font (#63). The ASK ME board now uses VT323 to match the
    rest of the memory surfaces, instead of the chunky Pixelify Sans.
  • Security — Slack download host-pinned. The Slack bot token is only ever sent to
    *.slack.com, a defense-in-depth guard added before the Authorization header is attached.

Everything from v0.2.5 (the packaging crash fix, autonomous Slack-request protocol, the
delegate toggle) and earlier is included.
See the CHANGELOG for full detail.

First launch

  • macOS — the build is signed with a Developer ID (hardened runtime). If macOS
    still shows an "unidentified developer" warning on first open, right-click the app →
    OpenOpen once. After that, the first time agents touch a folder you'll get a
    single macOS privacy prompt for Documents/Desktop/Downloads — allow it once and the
    grant sticks (it covers the claude agents the app spawns), because the grant is bound
    to the app's stable signature.
  • Windows — not code-signed yet; SmartScreen may show "Windows protected your PC" →
    More infoRun anyway.
  • Linux — make the AppImage executable: chmod +x Munder-Difflin-*.AppImage, then run it.

Requirements

  • macOS 12+, Windows 10/11, or a modern Linux desktop
  • Claude Code installed and on your PATH (and/or the Antigravity agy or OpenAI codex CLI for those providers)
  • A Claude Code subscription (Munder Difflin drives your existing claude CLI — it doesn't replace it)

🛠 Build from source

git clone https://github.com/chaitanyagiri/munder-difflin.git
cd munder-difflin
npm install        # rebuilds node-pty for Electron
npm run dev        # launches the app with hot reload

Node 18+ and a C/C++ toolchain are required (Xcode CLT on macOS, Build Tools on Windows).
To produce installers yourself: npm run dist (current OS), or dist:mac / dist:win / dist:linux.


What's inside

  • The simulation — every agent is a real claude (or agy / codex) pseudo-terminal, visualized as an avatar on a watchable office floor (node-pty · xterm.js · Pixi.js).
  • MemPalace — a markdown-first, semantic memory layer the whole office shares; cross-session recall in ~12ms.
  • GOD orchestrator + hive — one agent you talk to routes work to specialists and stays autonomous, escalating only critical items (spend, destructive ops, scope) to you natively, through Claude Code's human-in-the-loop prompts.
  • Plugs into your setup — your subscription, settings, skills, and MCP servers; /remote-control reaches the whole floor from your phone.
