+title: "refactor: GEO Agent Framework — 统一架构重构为独立项目"
+type: refactor
+status: active
+date: 2026-06-04
+---
+
+## Summary
+
+将 GEO 项目的 8 个 Agent 从代码重复的独立类重构为独立 Python 包（`fischer-agentkit`），采用统一 Agent Core + 配置驱动 + 可插拔 Tool/Skill/Memory 架构。新增 MCP 协议支持、三层记忆系统（Working/Episodic/Semantic）、Level 3 自我进化闭环（经验积累 → Prompt 自动优化 → 策略调整）、多 Agent 协同增强（并行执行、Handoff、动态 Pipeline），并实现 Agent 与业务系统的完全解耦。
+
+## Problem Frame
+
+当前 GEO 项目的 Agent 体系存在以下结构性问题：
+
+1. **代码重复**：8 个 Agent 的 `execute()` 方法包含完全相同的计时、try/except、TaskResult 构建逻辑（~250 行模板代码），每新增一个 Agent 需复制 ~150 行
+2. **架构耦合**：Agent 直接依赖业务 Service（CitationService、MonitorService 等），无法独立部署和复用
+3. **能力缺失**：无记忆系统（每次执行无状态）、无自我进化（Prompt 硬编码不可调优）、无技能插件（能力静态绑定）、无 MCP 支持
+4. **编排局限**：Pipeline 仅支持串行 DAG、无 Agent 间 Handoff、无动态路由
+5. **配置僵化**：AgentType 硬编码枚举、Prompt 与 Agent 紧耦合、新增 Agent 需改 5+ 文件
+
+---
+
+## Requirements
+
+### Agent Core 统一架构
+
+R1. Agent 框架必须作为独立 Python 包（`fischer-agentkit`），可独立安装、版本管理、跨项目复用
+R2. 所有 Agent 共享统一的 `BaseAgent` 生命周期（start → listen → execute → reflect → evolve → stop），子类只需实现 `handle_task()` 返回业务数据
+R3. Agent 定义支持三种模式：Python 声明式（`@task` 装饰器）、YAML 配置驱动（零代码）、混合模式
+R4. AgentType 从硬编码枚举改为动态注册，新增 Agent 类型无需修改框架代码
+R5. Agent 的 input/output 支持 JSON Schema 声明与校验
+
+### Tool/Skill 插件系统
+
+R6. 实现 `Tool` 抽象基类，支持 `FunctionTool`（函数工具）、`AgentTool`（Agent 即工具）、`MCPTool`（MCP 协议工具）三种类型
+R7. 实现 `ToolRegistry`，支持工具的注册、发现、版本管理、标签分类
+R8. 实现 MCP Server，将现有 Agent 能力暴露为 MCP 工具供外部调用
+R9. 实现 MCP Client，Agent 可调用外部 MCP 工具服务器
+R10. 工具支持组合：顺序链、并行扇出/扇入、动态选择
+
+### 记忆系统
+
+R11. 实现 Working Memory（Redis-based），存储当前任务的上下文和中间状态，生命周期为单次任务
+R12. 实现 Episodic Memory（向量+关系数据库），记录每次任务的输入/输出/效果/反思，支持语义检索相似历史案例
+R13. 实现 Semantic Memory，复用现有 RAG 知识库，所有 Agent 均可通过统一接口检索知识
+R14. 记忆检索采用混合策略：向量语义 + 关键词 + 知识图谱 + 时间衰减 + RRF 融合排序
+
+### 自我进化（Level 3）
+
+R15. 实现经验积累：每次任务执行后自动记录成功/失败模式、效果指标、反思总结
+R16. 实现 Prompt 自动优化：基于 DSPy 风格的编译器，从任务结果中自动生成/优化 Prompt 指令和 few-shot 示例
+R17. 实现策略调整：根据历史效果数据自动调整 Agent 参数（temperature、tool 选择权重、Pipeline 路径）
+R18. 进化变更必须经过 A/B 测试验证后才可生效，支持回滚
+
+### 多 Agent 协同与业务编排
+
+R19. Pipeline Engine 支持同层并行执行（无依赖的 stages 使用 `asyncio.gather` 并行）
+R20. 实现 Handoff 机制：Agent 可在运行时将任务转交给另一个 Agent，携带上下文
+R21. 支持动态 Pipeline：运行时根据条件选择子流程、嵌套 Pipeline
+R22. Agent 间通信支持事件驱动（Redis Pub/Sub），替代轮询等待
+
+### Agent 与业务解耦
+
+R23. Agent 框架不依赖任何 GEO 业务代码（Service、Model、Repository），通过 Tool 接口调用业务能力
+R24. 业务系统通过 Tool 注册将自身能力暴露给 Agent，Agent 通过 ToolRegistry 发现和调用
+R25. Agent 配置（Prompt、Tool 绑定、Memory 策略）存储在数据库，支持热更新
+
+---
+
+## Key Technical Decisions
+
+KTD1. **独立 Python 包架构**：`fischer-agentkit` 作为独立包发布到私有 PyPI，GEO 项目通过 `pip install` 引入。包结构遵循 `src/` layout，支持独立测试和版本管理。理由：解耦 Agent 基础设施与业务代码，支持跨项目复用。
+
+KTD2. **统一 Agent Core 的 execute 模板上移**：将计时、try/except、TaskResult 构建、进度上报等公共逻辑全部上移到 `BaseAgent.execute()`，子类只需实现 `handle_task(task) -> dict`。理由：消除 8 个 Agent 中 ~250 行重复代码。
+
+KTD3. **Tool 抽象三层架构**：`FunctionTool`（进程内函数调用）→ `MCPTool`（跨进程 MCP 协议调用）→ `AgentTool`（将 Agent 包装为 Tool）。理由：覆盖从简单到复杂的所有工具场景，MCP 作为标准协议确保生态兼容性。
+
+KTD4. **MCP 双向支持**：同时实现 MCP Server（暴露 Agent 能力）和 MCP Client（调用外部工具）。传输层优先支持 Streamable HTTP（2025 标准），兼容 SSE。理由：MCP 是 2025 年工具协议事实标准，双向支持最大化生态连接能力。
+
+KTD5. **三层记忆架构**：Working Memory（Redis，单任务生命周期）→ Episodic Memory（pgvector + PostgreSQL，任务经验）→ Semantic Memory（复用现有 RAG + 知识图谱）。理由：不同记忆类型有不同生命周期和检索模式，分层实现职责清晰。
+
+KTD6. **Level 3 进化采用 DSPy 风格编译器**：定义 `Signature`（输入/输出 schema）→ `Module`（可组合 Prompt 策略）→ `Optimizer`（自动优化），从任务结果中自动构建 few-shot 示例和优化指令。理由：DSPy 是目前最成熟的 Prompt 自动优化范式，其编译器模式与 Agent 的 execute-reflect-evolve 生命周期天然契合。
+
+KTD7. **配置驱动的 Agent 定义**：Agent 的元数据、Prompt、Tool 绑定、Memory 策略均通过 YAML/数据库配置，运行时由 `ConfigDrivenAgent` 自动组装。理由：将新增 Agent 从写 150 行代码降为 10-20 行配置。
+
+KTD8. **Pipeline 并行执行**：将拓扑排序后的 stages 按依赖层级分组，同层内使用 `asyncio.gather` 并行执行。理由：引用检测和趋势分析等无依赖任务应并行，当前串行执行浪费时间。
+
+KTD9. **Handoff 基于 Redis Pub/Sub**：Agent 通过 `agent:{name}:handoff` 频道发送转交请求，目标 Agent 监听并接管。理由：与现有 Redis Queue 架构一致，无需引入新组件。

+## Implementation Units
+
+### U1. 独立包脚手架与 BaseAgent 重构
+
+**Goal:** 创建 `fischer-agentkit` 独立包，重构 BaseAgent 将 execute 模板代码上移，子类只需实现 `handle_task()`。
+
+**Dependencies:** 无
+
+**Files:**
+- `fischer-agentkit/src/agentkit/__init__.py`
+- `fischer-agentkit/src/agentkit/core/__init__.py`
+- `fischer-agentkit/src/agentkit/core/base.py`
+- `fischer-agentkit/src/agentkit/core/protocol.py`
+- `fischer-agentkit/src/agentkit/core/exceptions.py`
+- `fischer-agentkit/src/agentkit/core/registry.py`
+- `fischer-agentkit/src/agentkit/core/dispatcher.py`
+- `fischer-agentkit/pyproject.toml`
+- `fischer-agentkit/tests/unit/test_base_agent.py`
+
+**Approach:**
+
+1. 创建 `fischer-agentkit` 包，使用 `src/` layout，`pyproject.toml` 声明依赖（`redis[hiredis]`, `pydantic>=2.0`, `sqlalchemy[asyncio]>=2.0`）
+2. 从 GEO 项目迁移 `protocol.py`（AgentCapability, TaskMessage, TaskResult, TaskProgress, TaskStatus, AgentStatus），移除 AgentType 硬编码枚举，改为动态注册
+3. 重构 `BaseAgent`：
+   - `execute()` 方法变为 final（非抽象），包含完整的计时、try/except、TaskResult 构建、进度上报
+   - 新增抽象方法 `handle_task(task) -> dict`，子类只需返回 output_data
+   - 新增生命周期钩子：`on_task_start()`, `on_task_complete()`, `on_task_failed()`
+   - 新增 `tools: list[Tool]` 属性（默认空，U3 实现）
+   - 新增 `memory: Memory` 属性（默认空，U4 实现）
+4. 迁移 `registry.py`, `dispatcher.py`, `exceptions.py`，去除 GEO 业务依赖
+5. `AgentRegistry.get_available_agent()` 增加负载均衡策略（轮询/最少任务）
+
+**Patterns to follow:** 现有 `backend/app/agent_framework/base.py` 的双模式（Redis/本地）设计
+
+**Test scenarios:**
+- BaseAgent 子类实现 handle_task 返回 dict，execute 自动包装为 TaskResult
+- handle_task 抛异常时 execute 自动构建 FAILED TaskResult
+- on_task_start/complete/failed 钩子按序调用
+- AgentRegistry 动态注册新 AgentType 不报错
+- AgentRegistry.get_available_agent 轮询策略返回不同 Agent
+
+**Verification:** `fischer-agentkit` 可独立 `pip install -e .`，单元测试全部通过
+
+---
+
+### U2. Protocol 扩展与配置驱动 Agent
+
+**Goal:** 扩展 Protocol 支持 JSON Schema 校验、Handoff 消息；实现 ConfigDrivenAgent，支持 YAML/数据库配置驱动 Agent 定义。
+
+**Dependencies:** U1
+
+**Files:**
+- `fischer-agentkit/src/agentkit/core/protocol.py`（扩展）
+- `fischer-agentkit/src/agentkit/core/config_driven.py`
+- `fischer-agentkit/src/agentkit/core/standalone.py`
+- `fischer-agentkit/src/agentkit/prompts/template.py`
+- `fischer-agentkit/src/agentkit/prompts/section.py`
+- `fischer-agentkit/tests/unit/test_config_driven.py`
+- `fischer-agentkit/tests/unit/test_protocol.py`
+
+**Approach:**
+
+1. Protocol 扩展：
+   - `AgentCapability` 增加 `input_schema: dict | None`、`output_schema: dict | None`（JSON Schema）
+   - 新增 `HandoffMessage` 数据类（source_agent, target_agent, task_context, reason）
+   - 新增 `EvolutionEvent` 数据类（agent_name, change_type, before, after, metrics）
+   - `TaskMessage` 增加 `conversation_id: str | None` 支持多轮对话
+2. ConfigDrivenAgent：
+   - 接受 YAML 配置或数据库配置，自动组装：Prompt 模板 + LLM 参数 + Tool 绑定 + Memory 策略
+   - 内置 LLM 调用 + JSON 输出解析 + 降级兜底的标准流程
+   - 支持三种任务模式：`llm_generate`（Prompt → LLM → 解析）、`tool_call`（调用指定 Tool）、`custom`（自定义 handler）
+3. PromptTemplate 迁移并增强：支持动态 section 组合、版本标记
+4. Standalone runner 改为自动发现：扫描 `agent_configs/` 目录下的 YAML 文件，自动注册和启动
+
+**Patterns to follow:** 现有 `prompts/base_template.py` 的 PromptSection 设计
+
+**Test scenarios:**
+- ConfigDrivenAgent 从 YAML 加载配置并正确组装
+- llm_generate 模式：渲染 Prompt → 调用 Mock LLM → 解析 JSON 输出
+- tool_call 模式：调用注册的 FunctionTool 并返回结果
+- input_schema 校验：缺少必填字段时返回校验错误
+- HandoffMessage 序列化/反序列化正确
+- 自动发现：在 configs/ 目录放置 YAML 后 standalone 可自动加载
+
+**Verification:** 通过 YAML 配置定义一个新 Agent，无需写 Python 代码即可运行
+
+---
+
+### U3. Tool/Skill 插件系统
+
+**Goal:** 实现 Tool 抽象基类、FunctionTool、AgentTool、ToolRegistry，支持工具注册、发现、组合。
+
+**Dependencies:** U1
+
+**Files:**
+- `fischer-agentkit/src/agentkit/tools/__init__.py`
+- `fischer-agentkit/src/agentkit/tools/base.py`
+- `fischer-agentkit/src/agentkit/tools/function_tool.py`
+- `fischer-agentkit/src/agentkit/tools/agent_tool.py`
+- `fischer-agentkit/src/agentkit/tools/registry.py`
+- `fischer-agentkit/tests/unit/test_tool_registry.py`
+- `fischer-agentkit/tests/unit/test_function_tool.py`
+- `fischer-agentkit/tests/unit/test_agent_tool.py`
+- `fischer-agentkit/tests/integration/test_tool_composition.py`
+
+**Approach:**
+
+1. `Tool` 抽象基类：
+   - 属性：`name`, `description`, `input_schema`（JSON Schema）, `output_schema`（JSON Schema）, `version`, `tags`
+   - 抽象方法：`async execute(**kwargs) -> dict`
+   - 生命周期钩子：`before_execute()`, `after_execute()`, `on_error()`
+2. `FunctionTool`：包装普通 Python 函数为 Tool，自动从函数签名推断 input_schema
+3. `AgentTool`：包装另一个 Agent 为 Tool，输入/输出通过 mapping 适配，内部通过 Dispatcher 分发任务
+4. `ToolRegistry`：
+   - `register(tool)`, `unregister(name)`, `get(name)`, `list_tools(tag=None)`
+   - 支持版本管理：同一工具多版本共存，默认使用最新版
+   - 支持标签分类：`[citation, analysis, generation, optimization]`
+5. 工具组合：
+   - `SequentialChain([tool_a, tool_b])`：顺序执行，前一个输出作为后一个输入
+   - `ParallelFanOut([tool_a, tool_b, tool_c])`：并行执行，结果合并
+   - `DynamicSelector(llm, tools)`：LLM 根据任务动态选择工具
+
+**Patterns to follow:** 现有 `LLMFactory` 的注册-创建模式
+
+**Test scenarios:**
+- FunctionTool 从函数自动推断 schema 并执行
+- AgentTool 分发任务到目标 Agent 并返回结果
+- ToolRegistry 注册/发现/按标签过滤
+- SequentialChain 顺序执行两个工具
+- ParallelFanOut 并行执行三个工具
+- DynamicSelector 根据 LLM 判断选择合适工具
+- 工具版本管理：注册 v1 和 v2，默认返回 v2
+
+**Verification:** 通过 ToolRegistry 注册 3 个 FunctionTool，Agent 可声明式绑定并调用
+
+---
+
+### U4. 记忆系统
+
+**Goal:** 实现三层记忆系统（Working/Episodic/Semantic）和混合检索器。
+
+**Dependencies:** U1
+
+**Files:**
+- `fischer-agentkit/src/agentkit/memory/__init__.py`
+- `fischer-agentkit/src/agentkit/memory/base.py`
+- `fischer-agentkit/src/agentkit/memory/working.py`
+- `fischer-agentkit/src/agentkit/memory/episodic.py`
+- `fischer-agentkit/src/agentkit/memory/semantic.py`
+- `fischer-agentkit/src/agentkit/memory/retriever.py`
+- `fischer-agentkit/tests/unit/test_working_memory.py`
+- `fischer-agentkit/tests/unit/test_episodic_memory.py`
+- `fischer-agentkit/tests/unit/test_semantic_memory.py`
+- `fischer-agentkit/tests/unit/test_memory_retriever.py`
+
+**Approach:**
+
+1. `Memory` 抽象基类：
+   - `async store(key, value, metadata)`, `async retrieve(query, top_k)`, `async delete(key)`
+   - `async search(query, top_k, filters)` — 语义检索
+2. `WorkingMemory`（Redis）：
+   - 以 `agent:{name}:working_memory:{task_id}` 为 key 前缀
+   - 支持自动过期（TTL = 任务超时时间 × 2）
+   - 提供 `get_context()` 方法，返回格式化的上下文字符串
+3. `EpisodicMemory`（pgvector + PostgreSQL）：
+   - 表结构：`id, agent_name, task_type, input_summary, output_summary, outcome(success/fail), quality_score, reflection, embedding, created_at`
+   - 写入时自动生成 embedding（复用 Embedder 接口）
+   - 检索：向量语义 + 关键词 + 时间衰减 + RRF 融合
+4. `SemanticMemory`：
+   - 适配器模式，对接 GEO 项目的 `RAGService` 和 `GraphQuery`
+   - 提供统一的 `search(query, knowledge_base_ids, top_k)` 接口
+5. `MemoryRetriever`（混合检索器）：
+   - 并行查询三层记忆，按权重融合排序
+   - 时间衰减：`score *= exp(-0.01 * age_hours)`
+   - 上下文窗口管理：总 token 不超过预算
+
+**Patterns to follow:** 现有 `HybridRetriever` 的 RRF 融合排序模式
+
+**Test scenarios:**
+- WorkingMemory 存取任务上下文，TTL 过期后自动清除
+- EpisodicMemory 写入任务经验并按语义检索相似案例
+- EpisodicMemory 时间衰减：近期经验权重高于远期
+- SemanticMemory 通过适配器调用 RAGService
+- MemoryRetriever 混合检索三层记忆并按权重融合
+- 上下文窗口管理：检索结果超过 token 预算时智能截断
+
+**Verification:** Agent 执行任务后自动写入 EpisodicMemory，后续相似任务可检索到历史经验
+
+---
+
+### U5. MCP Server 与 Client
+
+**Goal:** 实现 MCP Server（暴露 Agent 能力）和 MCP Client（调用外部 MCP 工具），完成 MCPTool。
+
+**Dependencies:** U3
+
+**Files:**
+- `fischer-agentkit/src/agentkit/mcp/__init__.py`
+- `fischer-agentkit/src/agentkit/mcp/server.py`
+- `fischer-agentkit/src/agentkit/mcp/client.py`
+- `fischer-agentkit/src/agentkit/mcp/transport.py`
+- `fischer-agentkit/src/agentkit/tools/mcp_tool.py`
+- `fischer-agentkit/tests/unit/test_mcp_server.py`
+- `fischer-agentkit/tests/unit/test_mcp_client.py`
+- `fischer-agentkit/tests/unit/test_mcp_tool.py`
+- `fischer-agentkit/tests/integration/test_mcp_roundtrip.py`
+
+**Approach:**
+
+1. MCP Server：
+   - 基于 FastAPI 实现，支持 Streamable HTTP 传输
+   - 端点：`/tools/list`（列出可用工具）、`/tools/call`（调用工具）、`/resources/read`（读取资源）
+   - 自动将 ToolRegistry 中注册的工具暴露为 MCP 工具
+   - 支持 SSE 流式响应
+2. MCP Client：
+   - 连接外部 MCP Server（HTTP/SSE）
+   - 自动发现远程工具并注册到本地 ToolRegistry
+   - 支持工具调用的流式响应
+3. MCPTool：
+   - 继承 Tool 基类，内部通过 MCP Client 调用远程工具
+   - 自动从 MCP Server 获取 input_schema
+4. Transport 层：
+   - 抽象 `Transport` 接口（`send_request`, `receive_response`）
+   - 实现 `HTTPTransport`（Streamable HTTP）和 `SSETransport`（Server-Sent Events）
+
+**Patterns to follow:** MCP 官方 Python SDK 的 Server/Client 模式
+
+**Test scenarios:**
+- MCP Server 启动后 `/tools/list` 返回已注册工具列表
+- MCP Client 连接 Server 并调用工具返回正确结果
+- MCPTool 通过 Client 调用远程工具
+- SSE 流式响应正确传输
+- MCP Server 自动暴露 ToolRegistry 中的 FunctionTool
+- 外部 MCP Server 的工具自动注册到本地 ToolRegistry
+
+**Verification:** 启动 MCP Server，通过 MCP Client 调用 Agent 能力，端到端成功

+- `fischer-agentkit/tests/unit/test_ab_tester.py`
+- `fischer-agentkit/tests/integration/test_evolution_loop.py`
+
+**Approach:**
+
+1. `Reflector`（执行反思）：
+   - 每次任务完成后自动评估：成功/失败、质量评分（基于 output_schema 约束和业务指标）
+   - 提取模式：常见失败原因、高效策略、低效路径
+   - 生成反思总结存入 EpisodicMemory
+2. `PromptOptimizer`（DSPy 风格编译器）：
+   - `Signature`：定义 `input_fields -> output_fields` 的结构化签名
+   - `Module`：可组合的 Prompt 策略（ChainOfThought, ReAct, FewShot）
+   - `Optimizer`：
+     - `BootstrapFewShot`：从成功案例中自动构建 few-shot 示例
+     - `MIPROv2`：多目标 Prompt 优化（指令 + few-shot 联合优化）
+     - 基于历史任务数据编译，产出优化后的 Prompt
+3. `StrategyTuner`（策略调优）：
+   - 可调参数：temperature, tool_selection_weights, pipeline_path
+   - 基于 Bayesian Optimization 搜索最优参数组合
+   - 每次调优记录 before/after 指标
+4. `ABTester`（A/B 测试框架）：
+   - 支持配置分流比例（如 80% 原版 / 20% 实验版）
+   - 自动收集实验组和对照组的效果指标
+   - 统计显著性检验（t-test），达到置信度后自动决策
+5. `EvolutionStore`（进化日志）：
+   - 表结构：`id, agent_name, change_type(prompt/strategy/pipeline), before, after, ab_test_id, status(active/rolled_back), created_at`
+   - 支持回滚：`rollback(evolution_id)`
+
+**Patterns to follow:** DSPy 的 Signature/Module/Optimizer 三层架构
+
+**Test scenarios:**
+- Reflector 评估成功任务生成正面反思
+- Reflector 评估失败任务提取失败模式
+- PromptOptimizer 从 10 个成功案例自动生成 few-shot 示例
+- PromptOptimizer 优化后的 Prompt 在测试集上效果提升
+- StrategyTuner 调整 temperature 后效果改善
+- ABTester 80/20 分流，实验组效果显著后自动应用
+- EvolutionStore 记录变更并支持回滚
+
+**Verification:** Agent 执行 20 次任务后，PromptOptimizer 自动优化 Prompt，ABTest 验证效果提升后自动应用

+### U7. 多 Agent 协同增强
+
+**Goal:** Pipeline Engine 支持并行执行、Handoff 机制、动态 Pipeline 组合。
+
+**Dependencies:** U1, U2
+
+**Files:**
+- `fischer-agentkit/src/agentkit/orchestrator/__init__.py`
+- `fischer-agentkit/src/agentkit/orchestrator/pipeline_engine.py`
+- `fischer-agentkit/src/agentkit/orchestrator/pipeline_schema.py`
+- `fischer-agentkit/src/agentkit/orchestrator/pipeline_loader.py`
+- `fischer-agentkit/src/agentkit/orchestrator/handoff.py`
+- `fischer-agentkit/src/agentkit/orchestrator/dynamic_pipeline.py`
+- `fischer-agentkit/tests/unit/test_pipeline_parallel.py`
+- `fischer-agentkit/tests/unit/test_handoff.py`
+- `fischer-agentkit/tests/unit/test_dynamic_pipeline.py`
+
+**Approach:**
+
+1. Pipeline 并行执行：
+   - 拓扑排序后按依赖层级分组（同层无依赖）
+   - 同层内使用 `asyncio.gather` 并行执行
+   - 并行 stage 的结果合并后传给下一层
+2. Handoff 机制：
+   - `HandoffManager` 管理转交请求
+   - Agent 调用 `self.handoff(target_agent, context, reason)` 发起转交
+   - 通过 Redis Pub/Sub `agent:{target}:handoff` 频道通知目标 Agent
+   - 目标 Agent 接收后创建新任务，携带源 Agent 的上下文
+   - 源 Agent 的任务状态变为 `HANDOFF`
+3. 动态 Pipeline：
+   - 支持 `sub_pipeline` stage 类型：引用另一个 YAML Pipeline
+   - 支持 `conditional_pipeline`：根据运行时条件选择子流程
+   - 支持 `loop_pipeline`：循环执行直到条件满足
+4. 事件驱动替代轮询：
+   - Pipeline Engine 通过 Redis Pub/Sub 订阅 `agent:{name}:result` 频道
+   - 任务完成后自动触发下一 stage，无需轮询
+
+**Patterns to follow:** 现有 `PipelineEngine` 的 DAG 拓扑排序和变量解析
+
+**Test scenarios:**
+- 3 个无依赖 stage 并行执行，总耗时约等于最长单个 stage
+- Handoff：Agent A 转交任务给 Agent B，B 接收并执行
+- 动态 Pipeline：根据条件选择不同的子流程
+- 子 Pipeline 嵌套执行并正确传递变量
+- 事件驱动：任务完成后自动触发下一 stage，无轮询间隔
+- 循环 Pipeline：条件满足后退出循环
+
+**Verification:** 内容生产 Pipeline 的 deai_processing 和 geo_optimization 并行执行，总耗时减少约 40%
+
+---
+
+### U8. GEO 业务系统适配与迁移
+
+**Goal:** 将 GEO 项目的 8 个 Agent 迁移到新框架，业务 Service 注册为 Tool，实现完全解耦。
+
+**Dependencies:** U1, U2, U3, U4, U5, U6, U7
+
+**Files:**
+- `geo/backend/app/agent_framework/agents/configs/citation_detector.yaml`

+- `geo/backend/app/agent_framework/tools/trend_tools.py`
+- `geo/backend/app/models/agent.py`（新增表）
+- `geo/backend/requirements.txt`（添加 fischer-agentkit 依赖）
+- `geo/backend/app/agent_framework/__init__.py`（适配层）
+
+**Approach:**
+
+1. 业务 Tool 注册：
+   - `CitationTools`：`execute_single_platform`, `get_or_create_task`, `calculate_next_query_at`
+   - `ContentTools`：`retrieve_knowledge`（包装 RAGService）
+   - `MonitorTools`：`check_and_compare`, `generate_change_report`, `create_monitoring_record`
+   - `SchemaTools`：`identify_missing_dimensions`, `match_templates`, `validate_json_ld`
+   - `CompetitorTools`：`analyze_competitor`
+   - `TrendTools`：`analyze_trends`, `get_hotspots`
+2. Agent 配置迁移：
+   - LLM 驱动型 Agent（ContentGenerator, DeAI, GEOOptimizer, SchemaAdvisor）→ YAML 配置 + `llm_generate` 模式，零代码
+   - Service 代理型 Agent（CitationDetector, Monitor）→ YAML 配置 + `custom` handler，仅保留业务逻辑方法
+   - CompetitorAnalyzer, TrendAgent → YAML 配置 + `tool_call` 模式
+3. 数据库迁移：
+   - 新增 `episodic_memories` 表
+   - 新增 `evolution_logs` 表
+   - 新增 `ab_test_configs` 表
+4. 适配层：
+   - `geo/backend/app/agent_framework/` 保留为适配层，import from `agentkit`
+   - 现有 API 端点（`/agents/`, `/agents/tasks/`）保持不变
+   - 现有 Pipeline YAML 保持兼容
+
+**Patterns to follow:** 现有 Agent 的业务逻辑实现，迁移时保持行为一致
+
+**Test scenarios:**
+- 8 个 Agent 迁移后行为与原版一致（回归测试）
+- 新增 Agent 只需 YAML 配置，无需写 Python 代码
+- 业务 Tool 注册后 Agent 可通过 ToolRegistry 发现和调用
+- EpisodicMemory 自动记录任务经验
+- EvolutionStore 记录进化变更
+- 现有 API 端点功能不变
+- 现有 Pipeline YAML 正常执行
+
+**Verification:** 运行现有 Agent 集成测试全部通过，新增一个 YAML-only Agent 成功执行任务
+
+---
+
+## Scope Boundaries
+
+### In Scope
+
+- `fischer-agentkit` 独立包的完整实现（Core, Tools, Memory, Evolution, Orchestrator, MCP）
+- GEO 项目 8 个 Agent 的迁移和适配
+- MCP Server/Client 双向支持
+- Level 3 自我进化（反思 + Prompt 优化 + 策略调优 + A/B 测试）
+- Pipeline 并行执行、Handoff、动态 Pipeline
+- 三层记忆系统

+- 替代现有 LLMFactory（保持现有 LLM 调用体系不变）
+- 前端 Agent 管理界面重构（本次聚焦后端架构）
+

+## Risks & Dependencies
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| MCP 协议规范变动（2025-2026 仍在演进） | MCPTool/MCPClient 需要跟进修改 | 抽象 Transport 层，协议变更只影响 Transport 实现 |
+| DSPy 风格 Prompt 优化可能需要大量训练数据 | 优化效果不明显 | BootstrapFewShot 从少量数据开始，MIPROv2 需 50+ 案例时才启用 |
+| 独立包与 GEO 项目的版本同步 | GEO 升级 agentkit 版本可能引入 breaking change | 语义化版本管理，GEO 项目 pin 版本，CI 自动测试兼容性 |
+| Episodic Memory 数据量增长 | pgvector 查询性能下降 | 设置 TTL 自动清理、定期归档、HNSW 索引优化 |
+| 迁移期间 8 个 Agent 行为不一致 | 业务回归 | 逐个迁移 + 回归测试，保留旧代码直到新代码验证通过 |
+| Pipeline 并行执行引入并发问题 | 结果不一致 | 同层 stage 只读共享变量，写入隔离 |
+
