Callers don't know if they're calling a web search API or a complex research system. This enables arbitrary composition and nesting.\n\n## Workflow\n\n### 1. Gather Requirements\n\nAsk the user:\n\n1. **Purpose**: What should this agent accomplish?\n2. **Inputs/Outputs**: What data goes in and comes out?\n3. **Tools**: What capabilities does it need? (existing tools or other agents)\n4. **Success Criteria**: How do we know the output is good?\n5. **Evaluator Types**: What quality dimensions matter? (see [evaluators.md](references/evaluators.md))\n\n### 2. Generate Agent Structure\n\nCreate this NestJS module structure:\n\n```\nsrc/agents/{agent-name}/\n├── {agent-name}.module.ts           # NestJS module\n├── {agent-name}.tool.ts             # Tool interface (public API)\n├── services/\n│   ├── orchestrator.service.ts      # Workflow coordination\n│   ├── planner.service.ts           # Plan generation\n│   ├── executor.service.ts          # Tool execution\n│   └── state.service.ts             # State management\n├── evaluators/\n│   ├── evaluator.registry.ts        # Registry service\n│   └── {type}.evaluator.ts          # Per evaluator type\n├── tools/\n│   └── tool.registry.ts             # Available tools\n├── entities/                         # TypeORM entities\n├── dto/                              # Input/output DTOs\n├── prompts/                          # LLM prompts\n├── config/\n│   └── {agent-name}.config.ts\n└── interfaces/\n```\n\n### 3. Implement Components\n\nFor each component, follow the patterns in:\n- [architecture.md](references/architecture.md) - Core interfaces, component roles, loops\n- [nestjs-patterns.md](references/nestjs-patterns.md) - NestJS service templates\n- [prompts.md](references/prompts.md) - System prompts for planner/executor/evaluators\n- [evaluators.md](references/evaluators.md) - Built-in evaluator types\n\n### 4. Wire Up Module\n\n```typescript\n@Module({\n  imports: [TypeOrmModule.forFeature([...entities])],\n  providers: [\n    OrchestratorService,\n    PlannerService,\n    ExecutorService,\n    StateService,\n    EvaluatorRegistry,\n    ...evaluators,\n    ToolRegistry,\n    AgentTool,\n  ],\n  exports: [AgentTool], // Only export the Tool interface\n})\nexport class AgentNameModule {}\n```\n\n## Key Architecture Rules\n\n1. **Uniform Interface**: Agent's public API is always `Tool.execute(input, context)`\n2. **Planning Loop**: plan → evaluate plan → revise → repeat (max iterations)\n3. **Execution Loop**: execute step → evaluate → retry with feedback → repeat\n4. **DAG Plans**: Steps declare dependencies; independent steps run in parallel\n5. **State Persistence**: All context, messages, plans, executions stored in PostgreSQL\n6. **Composition**: Agents can use other agents as tools transparently\n\n## Quick Reference\n\n### Tool Interface\n\n```typescript\ninterface Tool {\n  id: string;\n  name: string;\n  description: string;\n  inputSchema: JSONSchema;\n  outputSchema: JSONSchema;\n  execute(input: any, context?: ExecutionContext): Promise<ToolResult>;\n}\n```\n\n### Plan Structure\n\n```typescript\ninterface Plan {\n  id: string;\n  goal: string;\n  success_criteria: string[];\n  steps: PlanStep[];\n}\n\ninterface PlanStep {\n  id: string;\n  description: string;\n  tool_id: string;\n  input: any;\n  success_criteria: string[];\n  evaluator_type: string;\n  depends_on: string[];  // DAG dependencies\n}\n```\n\n### Default Config\n\n```typescript\nexport const agentConfig = {\n  maxDepth: 3,\n  maxPlanIterations: 3,\n  maxStepRetries: 3,\n  timeoutMs: 300000,\n  llm: { model: 'claude-sonnet-4-20250514', maxTokens: 4096 },\n};\n```\n\n## Composition Example\n\nAfter creating `research-agent` and `document-generator`:\n\n```typescript\n// document-generator/tools/tool.registry.ts\n@Injectable()\nexport class ToolRegistry {\n  constructor(private readonly researchTool: ResearchTool) {\n    this.register(this.researchTool);\n  }\n}\n```\n\nThe document generator's planner can now create steps using `research-system-v1` as a tool_id.\n","tagline":"Create composable AI agent systems in NestJS projects following the \"tools all the way down\" architecture.

Use this skill when users want to: (1) Create new AI agents with orchestrator/planner/executor/evaluator components, (2) Build agentic systems that can call other agents as tools, (3) Implement DAG-based planning with parallel execution, (4) Add database-backed state persistence for agent runs, (5) Create custom evaluators for quality assurance.
