router-based agent selection, (6) create parallel orchestrator-worker patterns, (7) implement agent handoffs, (8) design state schemas for multi-agent systems, or (9) debug multi-agent coordination issues.\n---\n\n# LangGraph Agent Patterns\n\nImplement and configure multi-agent coordination patterns for LangGraph applications.\n\n## Pattern Selection\n\nChoose the right pattern based on your coordination needs:\n\n| Pattern | Best For | When to Use |\n|---------|----------|-------------|\n| **Supervisor** | Complex workflows, dynamic routing | Agents need to collaborate, routing is context-dependent |\n| **Router** | Simple categorization, independent tasks | One-time routing, deterministic decisions |\n| **Orchestrator-Worker** | Parallel execution, high throughput | Independent subtasks, results need aggregation |\n| **Handoffs** | Sequential workflows, context preservation | Clear sequence, each agent builds on previous |\n\n**Quick Decision:**\n- **Dynamic routing needed?** → Supervisor\n- **Tasks can run in parallel?** → Orchestrator-Worker\n- **Simple categorization?** → Router\n- **Linear sequence?** → Handoffs\n\nFor detailed comparison: See references/pattern-comparison.md\n\n## Pattern Implementation Guides\n\n### Supervisor-Subagent Pattern\n\n**Overview:** Central coordinator delegates to specialized subagents based on context.\n\n**Quick Start:**\n\n```bash\n# Generate supervisor graph boilerplate\nuv run scripts/generate_supervisor_graph.py my-team \\\n  --subagents \"researcher,writer,reviewer\"\n\n# TypeScript\nuv run scripts/generate_supervisor_graph.py my-team \\\n  --subagents \"researcher,writer,reviewer\" \\\n  --typescript\n```\n\n**Key Components:**\n1. **State with routing**: `next` field for routing decisions\n2. **Supervisor node**: Makes routing decisions based on context\n3. **Subagent nodes**: Specialized agents with distinct capabilities\n4. **Conditional edges**: Route from supervisor to subagents\n\n**Example Flow:**\n```\nUser Request → Supervisor → Researcher → Supervisor → Writer → Supervisor → FINISH\n```\n\n**For complete implementation:** See references/supervisor-subagent.md\n\n### Router Pattern\n\n**Overview:** One-time routing to specialized agents based on initial request.\n\n**Key Components:**\n1. **State with route**: Single routing decision field\n2. **Router node**: Categorizes request (keyword, LLM, or semantic)\n3. **Specialized agents**: Independent agents for each category\n4. **Conditional routing**: Route to agent, then END\n\n**Example Flow:**\n```\nUser Request → Router → Sales Agent → END\n                   ├→ Support Agent → END\n                   └→ Billing Agent → END\n```\n\n**Routing Strategies:**\n- **Keyword-based**: Fast, simple string matching\n- **LLM-based**: Semantic understanding, flexible\n- **Embedding-based**: Similarity matching\n- **Model-based**: Fine-tuned classifier\n\n**For complete implementation:** See references/router-pattern.md\n\n### Orchestrator-Worker Pattern\n\n**Overview:** Decompose task into parallel subtasks, aggregate results.\n\n**Key Components:**\n1. **State with subtasks**: Task decomposition and results accumulation\n2. **Orchestrator node**: Splits task into independent subtasks\n3. **Worker nodes**: Process subtasks in parallel\n4. **Aggregator node**: Synthesizes results\n5. **Send fan-out**: Return `Send(...)` objects from conditional edges and use a list reducer (for example `Annotated[list[dict], operator.add]`) so worker outputs accumulate\n\n**Example Flow:**\n```\nTask → Orchestrator → Worker 1 ┐\n                  → Worker 2  ├→ Aggregator → Result\n                  → Worker 3 ┘\n```\n\n**Best Practices:**\n- Ensure subtasks are independent\n- Handle worker failures gracefully\n- Limit concurrent workers for resource management\n- Use LLM for result synthesis\n\n**For complete implementation:** See references/orchestrator-worker.md\n\n### Handoffs Pattern\n\n**Overview:** Sequential agent handoffs with context preservation.\n\n**Key Components:**\n1. **State with context**: Shared context across handoffs\n2. **Agent nodes**: Each agent hands off to next\n3. **Handoff logic**: Explicit or conditional handoffs\n4. **Context management**: Preserve and pass information\n\n**Example Flow:**\n```\nRequest → Researcher → Writer → Editor → FINISH\n         (with context preservation)\n```\n\n**Handoff Strategies:**\n- **Explicit**: Agent declares next agent\n- **Conditional**: Based on completion criteria\n- **Circular**: Agents can hand back for revisions\n\n**For complete implementation:** See references/handoffs.md\n\n## Examples\n\nRunnable mini-projects (Python + JavaScript):\n\n- `assets/examples/supervisor-example/`\n- `assets/examples/router-example/`\n- `assets/examples/orchestrator-example/`\n- `assets/examples/handoff-example/`\n\n## State Design for Multi-Agent Patterns\n\nEach pattern requires specific state schema design:\n\n**Supervisor Pattern:**\n```python\nclass SupervisorState(TypedDict):\n    messages: Annotated[list[BaseMessage], add_messages]\n    next: Literal[\"agent1\", \"agent2\", \"FINISH\"]\n    current_agent: str\n```\n\n**Router Pattern:**\n```python\nclass RouterState(TypedDict):\n    messages: list[BaseMessage]\n    route: Literal[\"category1\", \"category2\"]\n```\n\n**Orchestrator-Worker:**\n```python\nimport operator\nclass OrchestratorState(TypedDict):\n    task: str\n    subtasks: list[dict]\n    results: Annotated[list[dict], operator.add]\n```\n\n**Handoffs:**\n```python\nclass HandoffState(TypedDict):\n    messages: Annotated[list[BaseMessage], add_messages]\n    next_agent: str\n    context: dict\n```\n\n**For detailed state patterns:** See references/state-management-patterns.md\n\n## Validation and Visualization\n\n### Validate Graph Structure\n\n```bash\n# Validate agent graph for issues\nuv run scripts/validate_agent_graph.py path/to/graph.py:graph\n\n# Checks for:\n# - Unreachable nodes\n# - Cycles without termination\n# - Dead ends\n# - Invalid routing\n```\n\n### Visualize Graph\n\n```bash\n# Generate Mermaid diagram\nuv run scripts/visualize_graph.py path/to/graph.py:graph --output diagram.md\n\n# View in browser or IDE with Mermaid support\n```\n\n## Common Patterns and Anti-Patterns\n\n### Best Practices\n\n**1. Clear Agent Responsibilities**\n- Define non-overlapping capabilities\n- Document each agent's purpose\n- Avoid agent duplication\n\n**2. Loop Prevention**\n- Track iteration count in state\n- Set maximum iterations\n- Implement loop detection\n\n**3. Context Management**\n- Summarize context when it grows large\n- Only pass necessary information\n- Use structured context where possible\n\n**4. Error Handling**\n- Validate routing decisions\n- Handle invalid routes gracefully\n- Default to safe fallbacks\n\n### Anti-Patterns to Avoid\n\n**1. Over-Supervision**\n```python\n# ❌ Bad: Supervisor for simple linear flow\nUser → Supervisor → Agent1 → Supervisor → Agent2 → Supervisor\n\n# ✅ Good: Use handoffs instead\nUser → Agent1 → Agent2 → FINISH\n```\n\n**2. Complex Router Logic**\n```python\n# ❌ Bad: Complex routing rules in router\nif complex_condition_A and (condition_B or condition_C):\n    route = determine_complex_route()\n\n# ✅ Good: Use supervisor with LLM\nroute = llm.invoke(\"Analyze and route: {query}\")\n```\n\n**3. Unmanaged State Growth**\n```python\n# ❌ Bad: Accumulating all messages forever\nmessages: list[BaseMessage]  # Grows unbounded\n\n# ✅ Good: Summarize or limit\nif len(messages) > 20:\n    messages = summarize_context(messages)\n```\n\n## Debugging Multi-Agent Systems\n\n### 1. Trace Agent Flow\n\nUse LangSmith to visualize agent interactions:\n\n```python\nimport os\nos.environ[\"LANGSMITH_TRACING\"] = \"true\"\nos.environ[\"LANGSMITH_API_KEY\"] = \"<your-api-key>\"\nos.environ[\"LANGSMITH_PROJECT\"] = \"multi-agent-debug\"\n\nresult = graph.invoke(input_state)\n```\n\n### 2. Log Routing Decisions\n\nAdd logging to routing nodes:\n\n```python\ndef supervisor_node(state: SupervisorState) -> dict:\n    decision = make_routing_decision(state)\n\n    print(f\"Supervisor routing to: {decision}\")\n    print(f\"Current state: {len(state['messages'])} messages\")\n    print(f\"Iteration: {state.get('iteration', 0)}\")\n\n    return {\"next\": decision}\n```\n\n### 3. Validate Graph Structure\n\n```bash\n# Detect common issues\nuv run scripts/validate_agent_graph.py my_agent/graph.py:graph\n\n# Check for:\n# - Unreachable nodes\n# - Infinite loops\n# - Dead ends\n```\n\n### 4. Visualize Flow\n\n```bash\n# Generate diagram\nuv run scripts/visualize_graph.py my_agent/graph.py:graph -o flow.md\n```\n\n## Performance Optimization\n\n### Latency Optimization\n\n**Supervisor Pattern:**\n- Use faster models for routing (gpt-4o-mini)\n- Cache routing decisions\n- Implement early termination\n\n**Router Pattern:**\n- Use keyword matching for simple cases\n- Cache routing for similar queries\n- Avoid LLM calls when possible\n\n**Orchestrator-Worker:**\n- True parallelization already optimal\n- Limit worker count to avoid rate limits\n- Stream results to aggregator\n\n**Handoffs:**\n- Minimize context size\n- Skip unnecessary handoffs\n- Use cheaper models where appropriate\n\n### Cost Optimization\n\n**Token Usage:**\n- Summarize context regularly\n- Use structured output for reliability\n- Employ cheaper models for simple tasks\n\n**LLM Calls:**\n- Cache routing decisions\n- Use deterministic logic when possible\n- Batch similar requests\n\n**Pattern Selection:**\n- Router < Handoffs < Orchestrator < Supervisor (cost)\n\n## Testing Multi-Agent Patterns\n\n### Unit Test Routing Logic\n\n```python\ndef test_supervisor_routing():\n    \"\"\"Test supervisor routes correctly.\"\"\"\n    state = {\n        \"messages\": [HumanMessage(content=\"Need research\")],\n        \"next\": \"\",\n        \"current_agent\": \"\"\n    }\n\n    result = supervisor_node(state)\n    assert result[\"next\"] == \"researcher\"\n```\n\n### Integration Testing\n\n```python\ndef test_full_workflow():\n    \"\"\"Test complete multi-agent workflow.\"\"\"\n    graph = create_supervisor_graph()\n\n    result = graph.invoke({\n        \"messages\": [HumanMessage(content=\"Write article about AI\")]\n    })\n\n    # Verify agents were called in correct order\n    assert \"researcher\" in result[\"agent_history\"]\n    assert \"writer\" in result[\"agent_history\"]\n```\n\n### Test Graph Structure\n\n```bash\n# Validate before deployment\npython3 scripts/validate_agent_graph.py graph.py:graph\n```\n\n## Migration Between Patterns\n\n### Router to Supervisor\n\nWhen routing logic becomes complex:\n\n```python\n# Before: Complex router\ndef route(query):\n    if complex_rules(query):\n        return category\n\n# After: Supervisor with LLM\ndef supervisor(state):\n    return llm_routing_decision(state)\n```\n\n### Handoffs to Supervisor\n\nWhen need dynamic routing:\n\n```python\n# Before: Fixed sequence\nAgent1 → Agent2 → Agent3\n\n# After: Dynamic routing\nSupervisor ⇄ Agent1/Agent2/Agent3\n```\n\n### Sequential to Parallel\n\nWhen tasks become independent:\n\n```python\n# Before: Sequential\nAgent1 → Agent2 → Agent3\n\n# After: Parallel\nOrchestrator → [Agent1, Agent2, Agent3] → Aggregator\n```\n\n## Common Use Cases\n\n### Customer Support System\n\n**Pattern:** Router + Supervisor\n```\nRouter → Sales Supervisor → Sales Agents\n     ↓\n     Support Supervisor → Support Agents\n```\n\n### Research & Writing Pipeline\n\n**Pattern:** Supervisor or Handoffs\n```\nSupervisor ⇄ Researcher\n         ⇄ Writer\n         ⇄ Editor\n```\n\n### Data Analysis Pipeline\n\n**Pattern:** Orchestrator-Worker\n```\nOrchestrator → Data Collectors → Aggregator\n```\n\n### Document Processing\n\n**Pattern:** Orchestrator-Worker + Supervisor\n```\nRouter → PDF Orchestrator → Workers → Aggregator\n     ↓\n     DOCX Orchestrator → Workers → Aggregator\n```\n\n## Scripts Reference\n\n### generate_supervisor_graph.py\n\nGenerate supervisor-subagent boilerplate:\n\n```bash\nuv run scripts/generate_supervisor_graph.py <name> [options]\n\nOptions:\n  --subagents AGENTS    Comma-separated list (default: researcher,writer,reviewer)\n  -","tagline":"Implement multi-agent coordination patterns (supervisor-subagent, router, orchestrator-worker, handoffs) for LangGraph applications.
