What Multi Repo Swarm by spencermarx is

Multi Repo Swarm by spencermarx is a subagent published in the spencermarx/open-code-review repository on GitHub, which has about 369 stars. The repository describes itself as: “AI-powered multi-agent code review. Simulates a customizable team of Engineers performing code review with built-in discourse.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Multi Repo Swarm and get back a compact result.

How to install Multi Repo Swarm by spencermarx

Claude Code

  1. Download multi-repo-swarm.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Overview

Coordinate AI swarms across multiple repositories, enabling organization-wide automation and intelligent cross-project collaboration.

Core Features

1. Cross-Repo Initialization

# Initialize multi-repo swarm with gh CLI
# List organization repositories
REPOS=$(gh repo list org --limit 100 --json name,description,languages \
  --jq '.[] | select(.name | test("frontend|backend|shared"))')

# Get repository details
REPO_DETAILS=$(echo "$REPOS" | jq -r '.name' | while read -r repo; do
  gh api repos/org/$repo --jq '{name, default_branch, languages, topics}'
done | jq -s '.')

# Initialize swarm with repository context
npx claude-flow@v3alpha github multi-repo-init \
  --repo-details "$REPO_DETAILS" \
  --repos "org/frontend,org/backend,org/shared" \
  --topology hierarchical \
  --shared-memory \
  --sync-strategy eventual

2. Repository Discovery

# Auto-discover related repositories with gh CLI
# Search organization repositories
REPOS=$(gh repo list my-organization --limit 100 \
  --json name,description,languages,topics \
  --jq '.[] | select(.languages | keys | contains(["TypeScript"]))')

# Analyze repository dependencies
DEPS=$(echo "$REPOS" | jq -r '.name' | while read -r repo; do
  # Get package.json if it exists
  if gh api repos/my-organization/$repo/contents/package.json --jq '.content' 2>/dev/null; then
    gh api repos/my-organization/$repo/contents/package.json \
      --jq '.content' | base64 -d | jq '{name, dependencies, devDependencies}'
  fi
done | jq -s '.')

# Discover and analyze
npx claude-flow@v3alpha github discover-repos \
  --repos "$REPOS" \
…

3. Synchronized Operations

# Execute synchronized changes across repos with gh CLI
# Get matching repositories
MATCHING_REPOS=$(gh repo list org --limit 100 --json name \
  --jq '.[] | select(.name | test("-service$")) | .name')

# Execute task and create PRs
echo "$MATCHING_REPOS" | while read -r repo; do
  # Clone repo
  gh repo clone org/$repo /tmp/$repo -- --depth=1
  
  # Execute task
  cd /tmp/$repo
  npx claude-flow@v3alpha github task-execute \
    --task "update-dependencies" \
    --repo "org/$repo"
  
  # Create PR if changes exist
  if [[ -n $(git status --porcelain) ]]; then
…

Configuration

Multi-Repo Config File

# .swarm/multi-repo.yml
version: 1
organization: my-org
repositories:
  - name: frontend
    url: github.com/my-org/frontend
    role: ui
    agents: [coder, designer, tester]
    
  - name: backend
    url: github.com/my-org/backend
    role: api
    agents: [architect, coder, tester]
    
  - name: shared
    url: github.com/my-org/shared
    role: library

…

Repository Roles

// Define repository roles and responsibilities
{
  "roles": {
    "ui": {
      "responsibilities": ["user-interface", "ux", "accessibility"],
      "default-agents": ["designer", "coder", "tester"]
    },
    "api": {
      "responsibilities": ["endpoints", "business-logic", "data"],
      "default-agents": ["architect", "coder", "security"]
    },
    "library": {
      "responsibilities": ["shared-code", "utilities", "types"],
      "default-agents": ["analyst", "coder", "documenter"]

Orchestration Commands

Dependency Management

# Update dependencies across all repos with gh CLI
# Create tracking issue first
TRACKING_ISSUE=$(gh issue create \
  --title "Dependency Update: [email protected]" \
  --body "Tracking issue for updating TypeScript across all repositories" \
  --label "dependencies,tracking" \
  --json number -q .number)

# Get all repos with TypeScript
TS_REPOS=$(gh repo list org --limit 100 --json name | jq -r '.[].name' | \
  while read -r repo; do
    if gh api repos/org/$repo/contents/package.json 2>/dev/null | \
       jq -r '.content' | base64 -d | grep -q '"typescript"'; then
      echo "$repo"
    fi
  done)

Communication Strategies

1. Webhook-Based Coordination

// webhook-coordinator.js
const { MultiRepoSwarm } = require('ruv-swarm');

const swarm = new MultiRepoSwarm({
  webhook: {
    url: 'https://swarm-coordinator.example.com',
    secret: process.env.WEBHOOK_SECRET
  }
});

// Handle cross-repo events
swarm.on('repo:update', async (event) => {
  await swarm.propagate(event, {
    to: event.dependencies,
    strategy: 'eventual-consistency'
  });
});

2. GraphQL Federation

# Federated schema for multi-repo queries
type Repository @key(fields: "id") {
  id: ID!
  name: String!
  swarmStatus: SwarmStatus!
  dependencies: [Repository!]!
  agents: [Agent!]!
}

type SwarmStatus {
  active: Boolean!
  topology: Topology!
  tasks: [Task!]!
  memory: JSON!
}

3. Event Streaming

# Kafka configuration for real-time coordination
kafka:
  brokers: ['kafka1:9092', 'kafka2:9092']
  topics:
    swarm-events: 
      partitions: 10
      replication: 3
    swarm-memory:
      partitions: 5
      replication: 3

Advanced Features

1. Distributed Task Queue

# Create distributed task queue
npx claude-flow@v3alpha github multi-repo-queue \
  --backend redis \
  --workers 10 \
  --priority-routing \
  --dead-letter-queue

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
