Agent基类 ```typescript interface AgentConfig { name: string; role: string; capabilities: string[]; llm: LLMConfig; tools: Tool[]; instructions: string; } class BaseAgent { protected config: AgentConfig; protected memory: AgentMemory; constructor(config: AgentConfig) { this.config = config; this.memory = new AgentMemory(config.name); } async think(task: Task): Promise { const context = await this.memory.buildContext(task.description); const prompt = this.buildPrompt(task, context); const response = await this.callLLM(prompt); await this.memory.add({ type: 'semantic', content: task.description + ' -> ' + response.content, importance: 8 }); return response; } protected buildPrompt(task: Task, context: string): Message[] { return [ { role: 'system', content: this.config.instructions }, { role: 'system', content: context }, { role: 'user', content: task.description } ]; } protected async callLLM(messages: Message[]): Promise { const res = await fetch('https://api.openai.com/v1/chat/completions', { method: 'POST', headers: { 'Authorization': `Bearer ${process.env.OPENAI_API_KEY}` }, body: JSON.stringify({ model: this.config.llm.model, messages, tools: this.config.tools.map(t => t.definition) }) }); return res.json(); } } ``` ### 2. 编排器 ```typescript interface TaskResult { agentId: string; status: 'pending' | 'running' | 'done' | 'failed'; output?: string; dependencies: string[]; startTime?: number; endTime?: number; } class Orchestrator { private agents: Map = new Map(); private taskGraph: DAG; constructor(private llmRouter: LLMRouter) {} registerAgent(agent: BaseAgent) { this.agents.set(agent.config.name, agent); } async execute(goal: string): Promise { // 1. 任务分解 const plan = await this.decompose(goal); // 2. 构建DAG this.taskGraph = this.buildDAG(plan); // 3. 执行调度 const results = await this.schedule(); // 4. 汇总结果 return this.summarize(goal, results); } private async decompose(goal: string): Promise { const response = await this.llmRouter.route({ prompt: `将以下任务分解为可执行的子任务，返回JSON数组：目标: ${goal} 要求： - 每个子任务只由一个Agent负责 - 明确任务依赖关系 - 返回格式: [{"id":"t1","description":"...","agent":"researcher","depends":[]},...]`, system: '你是任务分解专家。' }); return JSON.parse(response.content); } private async schedule(): Promise> { const results = new Map(); const pending = new Set(this.taskGraph.nodes); const running: Promise[] = []; const maxConcurrent = 3; while (pending.size > 0 || running.length > 0) { // 启动可并行的任务 while (running.length < maxConcurrent) { const next = this.findNextRunnable(pending, results); if (!next) break; pending.delete(next.id); const p = this.runTask(next, results).catch(console.error); running.push(p); } // 等待一个完成 await Promise.race(running); running.splice(running.findIndex(p => false), 1); } return results; } private async runTask(task: Task, results: Map) { results.set(task.id, { agentId: task.agent, status: 'running', dependencies: task.depends || [], startTime: Date.now() }); try { // 等待依赖完成 for (const depId of task.depends || []) { const dep = results.get(depId); if (dep?.status !== 'done') { await this.waitFor(depId, results); } } const agent = this.agents.get(task.agent); const context = this.buildContext(task, results); const response = await agent.think({ id: task.id, description: task.description, context }); results.set(task.id, { ...results.get(task.id)!, status: 'done', output: response.content, endTime: Date.now() }); } catch (error) { results.set(task.id, { ...results.get(task.id)!, status: 'failed', output: String(error), endTime: Date.now() }); } } private buildContext(task: Task, results: Map): string { return (task.depends || []).map(depId => { const dep = results.get(depId); return dep?.output || ''; }).join('\n\n'); } } ``` ### 3. 消息总线 ```typescript class MessageBus { private subscriptions = new Map(); publish(channel: string, message: Message) { const subs = this.subscriptions.get(channel) || []; for (const sub of subs) { sub.handler(message); } } subscribe(channel: string, handler: (msg: Message) => void): () => void { if (!this.subscriptions.has(channel)) { this.subscriptions.set(channel, []); } const sub = { id: crypto.randomUUID(), handler }; this.subscriptions.get(channel)!.push(sub); return () => this.unsubscribe(channel, sub.id); } unsubscribe(channel: string, subId: string) { const subs = this.subscriptions.get(channel) || []; const idx = subs.findIndex(s => s.id === subId); if (idx >= 0) subs.splice(idx, 1); } } // 消息类型 interface Message { id: string; type: 'request' | 'response' | 'broadcast' | 'event'; from: string; to?: string; content: any; timestamp: number; } ``` ### 4. 状态机 ```typescript type AgentState = 'idle' | 'thinking' | 'waiting' | 'acting' | 'error'; interface AgentSession { id: string; agentId: string; state: AgentState; currentTask?: string; history: Turn[]; sharedContext: Record; } class StateManager { private sessions = new Map(); transition(sessionId: string, newState: AgentState) { const session = this.sessions.get(sessionId); if (!session) return; const oldState = session.state; session.state = newState; // 状态转换钩子 this.onTransition(sessionId, oldState, newState); } // 状态转换规则 private canTransition(from: AgentState, to: AgentState): boolean { const rules: Record = { idle: ['thinking'], thinking: ['waiting', 'acting', 'error', 'idle'], waiting: ['thinking', 'error', 'idle'], acting: ['thinking', 'error', 'idle'], error: ['idle', 'thinking'] }; return rules[from]?.includes(to) || false; } } ``` ## 通信模式 | 模式 | 说明 | 适用场景 | |------|------|----------| | 广播 | 所有Agent接收 | 全局通知 | | 点对点 | 指定Agent接收 | 任务分配 | | 发布/订阅 | 按主题分发 | 事件驱动 | | 黑板 | 共享知识空间 | 协作推理 | ## 常见模式 ### 角色扮演（Role Play） ```typescript class RolePlayOrchestrator extends Orchestrator { async execute(goal: string) { // 分配角色 const planner = this.getAgent('planner'); const executor = this.getAgent('executor'); const critic = this.getAgent('critic'); const plan = await planner.think({ description: goal }); const result = await executor.think({ description: plan.output, context: '' }); const review = await critic.think({ description: result.output, context: '' }); return review.output; } } ``` ### 辩论（Debate） ```typescript async debate(topic: string, rounds = 3) { const pro = this.getAgent('pro'); const con = this.getAgent('con'); const judge = this.getAgent('judge'); let context = ''; for (let i = 0; i < rounds; i++) { const proArg = await pro.think({ description: `正方论点 (第${i+1}轮): ${topic}`, context }); context += `\n正方: ${proArg.output}`; const conArg = await con.think({ description: `反方论点 (第${i+1}轮): ${topic}`, context }); context += `\n反方: ${conArg.output}`; } return judge.think({ description: `裁决: ${topic}`, context }); } ``` ## 最佳实践 1. **单一职责**：每个Agent有明确的专业领域 2. **松耦合**：通过消息总线通信，避免直接依赖 3. **超时控制**：防止某个Agent卡死 4. **熔断机制**：失败次数过多自动降级 5. **可观测性**：完整日志和追踪 ## Usage 1.
