multiclaude
Why tell Claude what to do when you can tell Claude to tell Claude what to do? A multi-agent orchestrator built on the Brownian ratchet philosophy — chaos in, progress out.
What Is Multiclaude?
Multiclaude spawns multiple autonomous Claude Code instances to coordinate work on a single repository. Each agent gets its own tmux window and git worktree. A supervisor agent acts as air traffic control, assigning tasks and nudging stuck workers. The system operates like a ratchet: as long as CI passes, PRs get merged. Progress is permanent.
This isn't about replacing developers. It's about changing what developers do. Less typing, more thinking. Less implementation, more architecture. Less grunt work, more judgment.
— Dan Lorenc, "A Gentle Introduction to multiclaude"Multiclaude frames software development as an MMORPG: your workspace is your character, workers are party members, the supervisor is the guild leader, and the merge queue is the raid boss guarding main. The system keeps running after you log off.
Architecture
The Brownian ratchet model: multiple autonomous agents create apparent chaos, but CI serves as a one-way gate that converts chaos into permanent forward progress.
┌─────────────────────────────────────────────────────────────┐ │ tmux session: mc-repo │ ├───────────────┬───────────────┬───────────────┬─────────────┤ │ supervisor │ merge-queue │ workspace │ worker-1 │ │ air traffic │ CI bouncer │ your shell │ task agent │ └───────────────┴───────────────┴───────────────┴─────────────┘ Agent Activity (Chaotic) CI Gate (Ratchet) Main Branch (Progress) ─────────────────────── ──> ─────────────────── ──> ─────────────────── worker-1: PR #42 tests pass? merge #42 worker-2: PR #43 tests pass? merge #43 worker-3: PR #44 tests fail reject #44 worker-3: PR #45 (fix) tests pass? merge #45
Chaos is Expected
Redundant work is cheaper than blocked work. Multiple agents may independently solve overlapping problems — and that is by design.
CI is King
If tests pass, ship it. If tests fail, fix it. CI is the only quality gate. No human approval required in singleplayer mode.
Forward > Perfect
Three okay PRs beat one perfect PR. The system optimizes for throughput and momentum, not polish.
Humans Approve
Agents propose, humans decide. In multiplayer mode, every PR goes through human review before merge.
Installation & Setup
Multiclaude is a single Go binary with minimal dependencies.
Prerequisites
- Go 1.21+ — for building from source
- tmux — terminal multiplexer for agent windows
- git — version control
- gh — GitHub CLI, authenticated
Install
# Install the latest version
go install github.com/dlorenc/multiclaude/cmd/multiclaude@latest
# Or build from source
git clone https://github.com/dlorenc/multiclaude.git
cd multiclaude
go build ./cmd/multiclaude
go install ./cmd/multiclaude
Quick Start
# 1. Start the multiclaude system
multiclaude start
# 2. Register a repository
multiclaude repo init https://github.com/your/repo
# 3. Spawn a worker with a task
multiclaude worker create "Add unit tests for the auth module"
# 4. Attach to the tmux session to watch agents work
tmux attach -t mc-repo
# 5. Detach with Ctrl-b d — agents keep running
Built-in Agents
Six specialized agent roles, each defined by a Markdown prompt file. Custom agents can extend the roster.
| Agent | Role | Description |
|---|---|---|
| Supervisor | Air Traffic Control | Coordinates all agents. Nudges stuck workers. Assigns and redistributes tasks. |
| Merge Queue | CI Bouncer | Singleplayer mode. Watches PRs, merges on CI pass. The ratchet mechanism. |
| PR Shepherd | Review Coordinator | Multiplayer mode. Coordinates human reviewers, manages review cycles. |
| Workspace | Personal Shell | Your direct Claude Code instance. Spawns workers on demand. |
| Worker | Task Executor | One task, one branch, one PR. The workhorse agent. |
| Reviewer | Code Reviewer | Reads PRs, leaves inline comments, checks quality. |
Custom Agents
Agents are defined by Markdown files — no code required. Store custom agent definitions per-repo or globally.
# Per-repo custom agent
~/.multiclaude/repos/<repo>/agents/docs-reviewer.md
# Team-shared agents (committed to repo)
.multiclaude/agents/docs-reviewer.md
# Spawn a custom agent
multiclaude agents spawn --name docs-bot --class docs-reviewer --prompt-file docs-reviewer.md
Singleplayer vs. Multiplayer
Fork detection is automatic. Initializing a fork enables PR Shepherd and disables Merge Queue.
Full Autonomy
PRs auto-merge when CI passes. No human review required. The merge-queue agent acts as the gatekeeper. Best for personal projects or repos where you trust the test suite completely.
The system runs unsupervised — spawn workers, detach from tmux, come back to merged PRs.
Team Review
PRs require human review before merge. The PR Shepherd agent coordinates reviewers, responds to feedback, and manages the review cycle. Best for team repos or open-source projects.
Agents still do the work, but humans make the final merge decision.
Usage & Commands
A minimal CLI surface. State lives in JSON files and the filesystem.
| Command | Purpose |
|---|---|
| multiclaude start | Initialize the multiclaude system |
| multiclaude repo init <url> | Register and configure a repository |
| multiclaude worker create "<task>" | Spawn a new worker agent with a task description |
| multiclaude agents spawn | Launch a named or custom agent |
| tmux attach -t mc-repo | Attach to the tmux session to watch agents work |
| Ctrl-b d | Detach from tmux (agents continue independently) |
Agent Spawn Flags
multiclaude agents spawn \
--name docs-bot \
--class docs-reviewer \
--prompt-file docs-reviewer.md
Public Libraries
pkg/tmux
Programmatic tmux control with multiline support. Create sessions, windows, panes, and send commands.
pkg/claude
Launch and interact with Claude Code instances programmatically. The building block for custom orchestrators.
Example Workflow
A real session adding features to a web application with three parallel workers.
Start and Initialize
Boot multiclaude and register your repo. The supervisor, merge-queue, and workspace agents spin up in tmux.
multiclaude start && multiclaude repo init https://github.com/you/webapp
Spawn Workers
Create three workers for independent tasks. Each gets its own git worktree and tmux window.
multiclaude worker create "Add OAuth2 login flow"
multiclaude worker create "Write unit tests for the API layer"
multiclaude worker create "Migrate CSS to Tailwind v4"
Agents Work Autonomously
Each worker creates a branch, makes changes, and opens a PR. The supervisor monitors progress and nudges stuck agents. You can watch via tmux attach -t mc-repo or walk away.
CI Runs, Merge Queue Acts
As PRs come in, CI runs tests. The merge-queue agent watches: pass = merge to main, fail = worker gets nudged to fix. Two workers might overlap — that's fine, the ratchet resolves it.
Come Back to Progress
Detach and return later. Workers that finished have their PRs merged. Workers that hit issues are waiting for your input or still iterating. Check main — it only moves forward.
multiclaude is a bet that the future of programming looks more like managing a team than writing code. Your job becomes setting direction, not typing characters.
— Dan LorencLimitations & Trade-offs
Every tool has edges. Multiclaude trades control for throughput.
- Duplicate work is expected. Multiple agents may independently solve overlapping problems. The ratchet merges both — cleanup may be needed.
- Self-described as "vibe-coded." The author acknowledges potential bugs and security flaws. It is experimental software.
- CI is the only safety net. If your test suite has gaps, bad code gets merged automatically in singleplayer mode.
- Token usage burns fast. Multiple concurrent Claude Code instances consume API credits or Max subscription limits rapidly.
- Fewer intervention points. In singleplayer mode, once workers are spawned you have limited ability to course-correct before merge.
- Requires strong CI. The entire philosophy depends on your test suite being comprehensive enough to serve as the quality gate.
- Go toolchain required. Unlike some tools that ship pre-built binaries, multiclaude currently requires Go for installation.
How It Compares
From Multiclaude's own documentation, comparing against Gas Town (Steve Yegge's orchestrator).
| Dimension | Gas Town | Multiclaude |
|---|---|---|
| Complexity | Higher | Lower |
| Best For | Solo / hobby projects | Team workflows |
| Parallel Agents | Stronger | Weaker |
| Long Autonomous Runs | Weaker | Stronger |
