Multi-Agent Coordination Strategies

Strategy 1: Shared Ollama Instance (RECOMMENDED - FREE)

// All agents share one local Ollama instance
import { ollama } from 'ollama-ai-provider';

const agents = {
  coordinator: createAgent({
    model: ollama('llama3.2'),  // FREE
    name: 'coordinator'
  }),
  researcher: createAgent({
    model: ollama('llama3.2'),  // FREE
    name: 'researcher'
  }),
  coder: createAgent({
    model: ollama('codellama'),  // FREE
    name: 'coder'
  }),
  reviewer: createAgent({
    model: ollama('llama3.2'),  // FREE
    name: 'reviewer'
  })
};

// 5 agents, 1,000 workflows/month = $0 cost

Hardware Requirements:

• 4 agents × Llama 3.2 7B: 32GB RAM minimum
• Concurrent requests: Limited by CPU cores
• See: ollama-local-ai plugin for detailed hardware sizing

Annual Cost: $0 (vs $360-3,600 for cloud APIs)

---

Strategy 2: Hybrid (Free for Development, Paid for Production)

const MODEL_CONFIG = {
  development: {
    coordinator: ollama('llama3.2'),      // FREE
    researcher: ollama('llama3.2'),       // FREE
    coder: ollama('codellama'),           // FREE
    reviewer: ollama('llama3.2')          // FREE
  },
  production: {
    coordinator: anthropic('claude-sonnet'),  // $15/1M tokens
    researcher: anthropic('claude-sonnet'),   // $15/1M tokens
    coder: anthropic('claude-sonnet'),        // $15/1M tokens
    reviewer: anthropic('claude-sonnet')      // $15/1M tokens
  }
};

const models = MODEL_CONFIG[process.env.NODE_ENV || 'development'];

Cost Reduction: $3,600/year → $300/year (92% savings) by using Ollama for dev/testing

---

Strategy 3: Rate Limit Coordinator (Paid APIs)

// Centralized rate limiter for paid APIs
class MultiAgentRateLimiter {
  private requestsThisMinute = 0;
  private lastReset = Date.now();
  private readonly RPM_LIMIT = 1000;  // Anthropic limit
  private readonly AGENTS_COUNT = 5;
  private readonly PER_AGENT_LIMIT = this.RPM_LIMIT / this.AGENTS_COUNT;  // 200 RPM per agent

  async executeAgentTask(agentName: string, task: () => Promise<any>) {
    // Reset counter every minute
    if (Date.now() - this.lastReset > 60000) {
      this.requestsThisMinute = 0;
      this.lastReset = Date.now();
    }

    // Wait if at limit
    while (this.requestsThisMinute >= this.RPM_LIMIT) {
      await new Promise(resolve => setTimeout(resolve, 1000));
      if (Date.now() - this.lastReset > 60000) {
        this.requestsThisMinute = 0;
        this.lastReset = Date.now();
      }
    }

    this.requestsThisMinute++;
    return await task();
  }
}

// All agents share the rate limiter
const rateLimiter = new MultiAgentRateLimiter();

// Agent execution
await rateLimiter.executeAgentTask('coordinator', async () => {
  return await coordinatorAgent.execute(task);
});

Result: Prevents 429 rate limit errors when running 5 agents concurrently

When to Use Paid APIs vs Ollama

Use Ollama (FREE) when:

• ✅ Development and testing multi-agent systems
• ✅ Running 1,000+ workflows/month (saves $360-3,600/year)
• ✅ Data privacy is critical (stays on your infrastructure)
• ✅ You have hardware (32GB+ RAM for 4-5 agents)
• ✅ Latency <2sec acceptable (not real-time)

Use Paid APIs when:

• ❌ Need <500ms latency for production
• ❌ Managing 10+ agents (hardware becomes expensive)
• ❌ Require enterprise SLA/support
• ❌ Can't manage local infrastructure

For 80% of multi-agent use cases: Ollama is sufficient and free.

💡 Core Concepts

Agent Handoffs

Problem: Single agent trying to do everything poorly Solution: Specialized agents handing off to experts

// Agent A realizes it needs help
await handoff({
  to: "code-expert",
  reason: "User needs implementation details",
  context: { requirement: "Build REST API" }
});

// Code expert takes over, provides implementation
// Returns to original agent

Intelligent Routing

Problem: Don't know which agent should handle the request Solution: Coordinator agent analyzes and routes automatically

const coordinator = createAgent({
  name: "coordinator",
  routes: [
    { to: "researcher", when: "needs information gathering" },
    { to: "coder", when: "needs code implementation" },
    { to: "reviewer", when: "needs quality check" }
  ]
});

Agent Coordination

Problem: Multiple agents need to work together on complex tasks Solution: Orchestrated workflow with automatic context passing

// Workflow: Research → Code → Review → Deploy
const result = await orchestrate([
  { agent: "researcher", task: "Find best practices" },
  { agent: "coder", task: "Implement solution" },
  { agent: "reviewer", task: "Review code" },
  { agent: "deployer", task: "Deploy to production" }
]);

🔧 Configuration

Agent Definition

interface AgentConfig {
  name: string;                    // Unique agent identifier
  model: LanguageModel;           // AI model (Claude, GPT-4, etc.)
  system: string;                 // System prompt/specialization
  tools?: Record<string, Tool>;   // Available tools
  handoffTo?: string[];           // Which agents can receive handoffs
  routes?: Route[];               // Routing rules (for coordinators)
  maxIterations?: number;         // Max handoff chain length
  temperature?: number;           // Model creativity (0-1)
}

Routing Rules

interface Route {
  to: string;                     // Target agent name
  when: string;                   // Condition description
  priority?: number;              // Route priority (higher = checked first)
}

Orchestration Options

}

---

💡 Best Practices

1. Clear Agent Specializations

// ❌ Bad: Too broad
const agent = createAgent({
  system: 'You are a helpful assistant'
});

// ✅ Good: Specific expertise
const agent = createAgent({
  system: 'You are an expert TypeScript developer specializing in React hooks and performance optimization'
});

2. Limit Handoff Chains

// Prevent infinite handoff loops
const config = {
  maxDepth: 5,  // Max 5 handoffs
  maxIterations: 10
};

3. Provide Context

// Pass context during handoffs
await handoff({
  to: 'coder',
  context: {
    architecture: designDoc,
    requirements: userRequirements,
    constraints: performanceGoals
  }
});

4. Handle Failures

try {
  const result = await orchestrate({...});
} catch (error) {
  if (error.type === 'HANDOFF_FAILED') {
    // Handle handoff failure
    await fallbackAgent.handle(task);
  } else if (error.type === 'TIMEOUT') {
    // Handle timeout
    console.log('Orchestration timed out');
  }
}

5. Monitor Performance

const result = await orchestrate({
  ...,
  onHandoff: (event) => {
    console.log(`Handoff: ${event.from} → ${event.to}`);
    console.log(`Reason: ${event.reason}`);
  },
  onComplete: (result) => {
    console.log(`Total handoffs: ${result.handoffCount}`);
    console.log(`Total time: ${result.duration}ms`);
  }
});
