Multi-Repo Swarm - Cross-Repository Swarm Orchestration

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 ruv-swarm 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 ruv-swarm github discover-repos \
  --repos "$REPOS" \
  --dependencies "$DEPS" \
  --analyze-dependencies \
  --suggest-swarm-topology

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/$repo
  npx ruv-swarm github task-execute \
    --task "update-dependencies" \
    --repo "org/$repo"

  # Create PR if changes exist
  if [[ -n $(git status --porcelain) ]]; then
    git checkout -b update-dependencies-$(date +%Y%m%d)
    git add -A
    git commit -m "chore: Update dependencies"

    # Push and create PR
    git push origin HEAD
    PR_URL=$(gh pr create \
      --title "Update dependencies" \
      --body "Automated dependency update across services" \
      --label "dependencies,automated")

    echo "$PR_URL" >> /tmp/created-prs.txt
  fi
  cd -
done

# Link related PRs
PR_URLS=$(cat /tmp/created-prs.txt)
npx ruv-swarm github link-prs --urls "$PR_URLS"

Orchestration Commands

Dependency Management

# Update dependencies across all repos with gh CLI
# Create tracking issue first
TRACKING_ISSUE=$(gh issue create \
  --title "Dependency Update: typescript@5.0.0" \
  --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)

# Update each repository
echo "$TS_REPOS" | while read -r repo; do
  # Clone and update
  gh repo clone org/$repo /tmp/$repo -- --depth=1
  cd /tmp/$repo

  # Update dependency
  npm install --save-dev typescript@5.0.0

  # Test changes
  if npm test; then
    # Create PR
    git checkout -b update-typescript-5
    git add package.json package-lock.json
    git commit -m "chore: Update TypeScript to 5.0.0

Part of #$TRACKING_ISSUE"

    git push origin HEAD
    gh pr create \
      --title "Update TypeScript to 5.0.0" \
      --body "Updates TypeScript to version 5.0.0\n\nTracking: #$TRACKING_ISSUE" \
      --label "dependencies"
  else
    # Report failure
    gh issue comment $TRACKING_ISSUE \
      --body "❌ Failed to update $repo - tests failing"
  fi
  cd -
done

Refactoring Operations

# Coordinate large-scale refactoring
npx ruv-swarm github multi-repo-refactor \
  --pattern "rename:OldAPI->NewAPI" \
  --analyze-impact \
  --create-migration-guide \
  --staged-rollout

Security Updates

# Coordinate security patches
npx ruv-swarm github multi-repo-security \
  --scan-all \
  --patch-vulnerabilities \

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

Synchronization Patterns

1. Eventually Consistent

// Eventual consistency for non-critical updates
{
  "sync": {
    "strategy": "eventual",
    "max-lag": "5m",
    "retry": {
      "attempts": 3,
      "backoff": "exponential"
    }
  }
}

2. Strong Consistency

// Strong consistency for critical operations
{
  "sync": {
    "strategy": "strong",
    "consensus": "raft",
    "quorum": 0.51,
    "timeout": "30s"
  }
}

3. Hybrid Approach

// Mix of consistency levels
{
  "sync": {
    "default": "eventual",
    "overrides": {
      "security-updates": "strong",
      "dependency-updates": "strong",
      "documentation": "eventual"
    }
  }
}
