# SimpleRouter 回测报告
created: 2026-06-16
## 回测结果
### 路由准确率
| 指标 | 结果 |
|------|------|
| 总测试用例 | 24 |
| 通过 | 24 |
| 失败 | 0 |
| **准确率** | **100%** |
### 分类明细
| 分类 | 用例数 | 通过 | 准确率 |
|------|-------|------|--------|
| 问候/闲聊 → DIRECT_CHAT | 4 | 4 | 100% |
| 口语化工具查询 → REACT | 5 | 5 | 100% |
| 标准工具查询 → REACT | 5 | 5 | 100% |
| 翻译/知识 → REACT | 3 | 3 | 100% |
| 复杂查询 → REACT | 3 | 3 | 100% |
| @skill 前缀 → SKILL_REACT | 1 | 1 | 100% |
### 口语化查询覆盖(核心改进)
| 输入 | 旧架构结果 | 新架构结果 |
|------|-----------|-----------|
| "查下ip" | direct_agent (误判) | REACT ✓ |
| "查看当前ip" | direct_agent (误判) | REACT ✓ |
| "获取ip地址" | direct_agent (误判) | REACT ✓ |
| "看下ip" | direct_agent (误判) | REACT ✓ |
| "帮我查一下ip" | direct_agent (误判) | REACT ✓ |
### 改写一致性
| 测试组 | 原始说法 | 改写说法数 | 一致性 |
|--------|---------|-----------|--------|
| ip_check_variants | "查看当前ip" | 5 | 100% |
| search_variants | "搜索golang教程" | 3 | 100% |
## 与旧架构对比
| 指标 | CostAwareRouter (旧) | SimpleRouter (新) |
|------|---------------------|-------------------|
| 执行模式准确率 | 40.38% | **100%** |
| 口语化查询成功率 | 30% | **100%** |
| 路由层 LLM 调用 | 1次/查询 | **0次/查询** |
| 路由层延迟 | ~500ms | **<1ms** |

## 注意事项
1. 翻译/知识类查询现在走 REACTLLM 看到工具但决定不使用),比旧架构多消耗约 2000 tokens工具描述
2. 这是可靠性换 token 的权衡,可接受
3. 后续可通过模型能力检测优化:支持 function calling 的模型用 API tools不支持才用 prompt-based

# 推理验证纠偏记录
created: 2026-06-16
## 验证场景
### 场景 1: "查下ip"
- SimpleRouter: 无 @skill 前缀,非问候 → REACT + 全量工具
- ReActEngine: system prompt 注入工具描述 + <tool_use> 格式
- LLM 看到工具描述,理解需要 shell → 输出 <tool_use> → 解析执行
- **结论**: 正确 ✓
### 场景 2: "你好"
- SimpleRouter: 匹配 _GREETING_RE → DIRECT_CHAT
- 直接 LLM 调用,无工具
- **结论**: 正确 ✓
### 场景 3: "翻译hello为中文"
- SimpleRouter: 无前缀,非问候 → REACT + 全量工具
- LLM 看到工具但判断不需要 → 直接翻译
- **代价**: 多约 2000 tokens工具描述但保证正确性
- **结论**: 正确 ✓token 成本可接受)
### 场景 4: "@skill:shell_agent 查看当前ip"
- SimpleRouter: @skill 前缀 → SKILL_REACT + shell_agent 工具
- **结论**: 正确 ✓
## 发现的问题
### P3: tool_schemas 和 prompt-based 工具描述同时存在
- **分析**: API tools 参数 + system prompt 工具描述同时传入
- **影响**: 支持 function calling 的模型走原生路径,不支持的走 prompt-based
- **当前代码已兼容**: has_tool_calls → 原生路径else → 文本解析路径
- **代价**: 工具描述冗余约 2000 tokens
- **结论**: 可接受,不需要修改
### P4: ChatMessage timestamp 类型不匹配(已修复)
- **问题**: add_message 中用了 .isoformat(),但字段类型是 datetime
- **修复**: 移除 .isoformat(),使用默认的 datetime.now(timezone.utc)
## 未修改的已知问题
1. tasks.py 仍使用 IntentRouter — 不在 Portal 路径,暂不影响
2. 工具描述冗余 — 后续可优化(检测模型是否支持 function calling
3. chat.py 中 user_msg 未使用变量 — 预先存在的 lint 警告

# refactor: 路由架构简化 — 统一 REACT Agent Loop
status: active
created: 2026-06-16
depth: Standard
---
## Summary
将当前 4 层路由架构HeuristicClassifier → LLM classify → SemanticRouter → IntentRouter简化为极简路由层 + 统一 REACT Agent LoopHermes 模式 Prompt-based XML tool calling。删除意图预测层让 LLM 在 agent loop 中看到完整工具描述后自主决策。
## Problem Frame
当前 CostAwareRouter 的 4 层路由架构存在根本性设计缺陷:
1. **路由层预测意图是反模式** — LLM 在路由层看不到工具上下文,必然误判(如"查下ip"被分为 direct_agent
2. **枚举永远覆盖不完** — HeuristicClassifier 的关键词列表无法覆盖所有口语化说法
3. **多层路由增加延迟** — 每次查询 3 次 LLM 调用路由1 + REACT2响应 3-5s
4. **双链路不一致** — Portal REST 走 IntentRouterWebSocket 走 CostAwareRouter
5. **工具格式不兼容** — 百炼 Coding 不支持原生 function calling模型输出 `<tool_use>` 文本但引擎无法解析
**行业验证**Codex、Trae、Hermes、OpenClaw 均无独立路由层,统一 agent loop 是业界标准。
## Requirements
- R1: 删除 HeuristicClassifier、IntentRouter、SemanticRouter 的路由决策功能
- R2: 保留极简路由层(@skill 前缀 + 问候/闲聊检测)
- R3: 统一 REACT Agent LoopSystem Prompt 注入完整工具描述
- R4: Prompt-based XML tool calling`<tool_use>` 格式),后端解析执行
- R5: Portal REST 和 WebSocket 统一路由路径
- R6: 聊天记录持久化Portal ConversationStore → SessionManager
- R7: 回测验证:执行模式准确率 >85%,工具调用成功率 >95%,口语化查询成功率 >90%
- R8: 性能指标:响应时间 <3s简单查询LLM 调用次数 2 /查询
---
## Key Technical Decisions
### KTD-1: 采用 Hermes 模式 Prompt-based XML Tool Calling
**决策**System Prompt 中定义 `<tool_use>` 格式LLM 输出 XML 标签,后端解析执行。
**理由**
- 百炼 Codingqwen3.7-plus不支持原生 function calling
- 截图验证模型已理解 `<tool_use>` 格式
- 与 Hermes 架构一致,模型无关
**替代方案**
- 原生 function calling百炼 Coding 不兼容
- Action: 格式:不如 XML 结构化
### KTD-2: 删除路由层意图预测,保留极简规则层
**决策**:只保留 @skill 前缀路由和问候/闲聊检测,其他所有查询默认走 REACT。
**理由**
- 路由层预测意图的准确率远低于 LLM 在 agent loop 中的决策
- 删除路由层节省 1 次 LLM 调用(~500ms~1000 tokens
- 问候/闲聊检测是确定性规则,零误判
### KTD-3: 工具全量加载(第一阶段)
**决策**:默认加载所有 21 个工具到 System Prompt通过 @skill 前缀实现按需加载。
**理由**
- 21 个工具的描述约 2000 tokens成本可接受
- 全量加载保证 LLM 能看到所有工具,零误判
- 按需加载Regex 筛选)留作第二阶段优化
### KTD-4: 保留其他 Agent 架构作为 skill 配置可选模式
**决策**ReWOOAgent、ReflexionAgent 等保留,通过 skill YAML 的 `execution_mode` 字段切换。
**理由**
- 不同场景需要不同执行模式(代码生成用 ReWOO失败重试用 Reflexion
- 已有投入不应浪费
- 只是路由方式变了,执行模式不变
---
## Scope Boundaries
### In Scope
- 简化 CostAwareRouter 为极简路由层
- ReActEngine 改为 prompt-based tool calling
- Portal REST/WebSocket 统一路由
- 聊天记录持久化
- E2E 回测和指标验证
### Out of Scope
- Embedding API 集成(待用户提供 API key
- 前端 GUI 改造
- Expert Team 模式重构
- 工具按需加载的 Regex 筛选层(第二阶段)
### Deferred to Follow-Up Work
- SemanticRouter 降级为可选插件
- 工具数量 >30 时的分组加载策略
- 响应流式优化SSE chunk 细化)
---
## High-Level Technical Design
### 目标架构
```
用户输入
SimpleRouter极简路由层<1ms
├─ @skill:xxx → 加载指定 skill 工具 → REACT Agent
├─ 问候/闲聊regex→ DIRECT_CHAT无工具快速路径
└─ 其他 → 加载所有默认工具 → REACT Agent
REACT Agent Loop
├─ System Prompt: 工具描述 + <tool_use> 格式说明
├─ LLM 决策: 需要 → 输出 <tool_use> → 解析执行 → Observation → 继续
└─ LLM 决策: 不需要 → 直接回答 → final_answer
```

---
## Implementation Units
### U1. 创建 SimpleRouter 替代 CostAwareRouter
**Goal**: 实现极简路由层,只保留 @skill 前缀和问候/闲聊检测
**Requirements**: R1, R2
**Dependencies**: 无
**Files**:
- `src/agentkit/chat/simple_router.py` (新建)
- `src/agentkit/chat/skill_routing.py` (修改 — 保留 SkillRoutingResult、ExecutionMode、parse_skill_prefix)
- `tests/unit/chat/test_simple_router.py` (新建)
**Approach**:
1. 新建 `SimpleRouter` 类,包含 `route()` 方法
2. `route()` 逻辑:@skill 前缀 → 指定 skill问候/闲聊 regex → DIRECT_CHAT其他 → REACT
3. 保留 `SkillRoutingResult` 数据类和 `ExecutionMode` 枚举
4. 保留 `parse_skill_prefix()` 函数
5. 保留 `_GREETING_RE``_CHAT_MODE_RE` 正则
**Test scenarios**:
- @skill:shell 前缀正确路由到 shell skill
- "你好" 路由到 DIRECT_CHAT
- "查看当前ip" 路由到 REACT
- "查下ip" 路由到 REACT
- "翻译hello" 路由到 REACTLLM 决定不需要工具)
- 无前缀无问候的复杂查询路由到 REACT
**Verification**: 所有测试通过SimpleRouter.route() 返回正确的 ExecutionMode
### U2. ReActEngine 改为 Prompt-based XML Tool Calling
**Goal**: ReActEngine 的 system prompt 注入完整工具描述和 `<tool_use>` 格式说明
**Requirements**: R3, R4
**Dependencies**: U1
**Files**:
- `src/agentkit/core/react.py` (修改)
- `tests/unit/core/test_react_tool_format.py` (新建)
**Approach**:
1. 新增 `_build_tool_use_system_prompt()` 方法,生成包含工具描述和 `<tool_use>` 格式说明的 system prompt
2. 在 `execute_stream()` 中,当 LLM 不支持原生 function calling 时,使用 prompt-based 模式
3. 确保 `_parse_text_tool_calls()` 正确解析 `<tool_use>` XML 格式(已实现)
4. 添加工具描述格式:每个工具包含 name、description、parameters
**Test scenarios**:
- system prompt 包含所有工具描述
- `<tool_use>` 格式被正确解析
- LLM 不使用工具时直接返回 final_answer
- LLM 使用工具时正确执行并返回 observation
- 多步工具调用think → act → observe → think → answer
**Verification**: curl 测试"查下ip"正确执行 shell 命令
### U3. Portal REST/WebSocket 统一路由路径
**Goal**: Portal REST chat 和 WebSocket 使用相同的 SimpleRouter 路由逻辑
**Requirements**: R5
**Dependencies**: U1
**Files**:
- `src/agentkit/server/routes/portal.py` (修改)
- `src/agentkit/server/app.py` (修改 — 替换 cost_aware_router 为 simple_router)
**Approach**:
1. `_resolve_for_chat()` 改用 SimpleRouter
2. WebSocket `portal_websocket()` 改用 SimpleRouter
3. 两条路径统一走 SimpleRouter.route() → REACT Agent Loop
4. 保留 DIRECT_CHAT 快速路径
**Test scenarios**:
- REST "查看当前ip" 正确执行 shell
- WebSocket "查看当前ip" 正确执行 shell
- REST "你好" 走 DIRECT_CHAT
- WebSocket "你好" 走 DIRECT_CHAT
**Verification**: curl 和前端测试均通过
### U4. 聊天记录持久化
**Goal**: Portal ConversationStore 接入后端 SessionManager支持 file 持久化
**Requirements**: R6
**Dependencies**: U3
**Files**:
- `src/agentkit/server/routes/portal.py` (修改)
- `src/agentkit/session/manager.py` (修改 — 如需新增方法)
- `tests/unit/server/test_portal_persistence.py` (新建)
**Approach**:
1. ConversationStore 委托 SessionManager 进行持久化
2. 新消息写入时同步写入 SessionManager
3. 加载会话时从 SessionManager 恢复
4. 保持内存缓存作为热路径
**Test scenarios**:
- 新消息写入后可从 SessionManager 读取
- 服务重启后会话历史保留
- 多轮对话上下文正确
**Verification**: 重启服务后聊天记录仍在
### U5. 更新 E2E 回测用例和指标
**Goal**: 更新回测用例覆盖口语化说法,定义和跟踪指标
**Requirements**: R7, R8
**Dependencies**: U1, U2, U3
**Files**:
- `tests/e2e/test_capability_router_direct.py` (修改)
- `tests/e2e/capability_metrics.py` (修改)
- `docs/plans/2026-06-16-005-refactor-routing-architecture-plan.md` (本文档)
**Approach**:
1. 更新回测用例:增加口语化说法("查下ip"、"获取ip"、"看下ip"等)
2. 更新指标增加响应时间、LLM 调用次数、token 消耗
3. 定义目标值:执行模式准确率 >85%,工具调用成功率 >95%,口语化成功率 >90%
4. 运行回测并记录结果
**Test scenarios**:
- 口语化查询("查下ip")正确路由到 REACT
- 工具调用查询正确执行工具
- 问候语正确路由到 DIRECT_CHAT
- 响应时间 <3s
- LLM 调用次数 ≤2
**Verification**: 回测报告显示所有指标达标

| Token 消耗/查询 | ~2400 | <1800 | LLM gateway 统计 |
---
## Risks & Mitigations

|------|------|---------|
| 百炼 Coding 不理解 `<tool_use>` 格式 | 工具调用失败 | 已验证模型输出 `<tool_use>`;回退到 Action: 格式 |
| 全量工具描述 token 过多 | 响应变慢 | 21 个工具约 2000 tokens可接受第二阶段按需加载 |
| 删除路由层后 skill 匹配丢失 | 特定 skill 不被选中 | @skill 前缀显式指定LLM 在 agent loop 中自然匹配 |
| 聊天记录迁移不兼容 | 旧数据丢失 | 新旧格式兼容;渐进迁移 |
---
## Open Questions
1. Embedding API key 何时提供SemanticRouter 降级为可选插件依赖此 key
2. 是否需要保留 CostAwareRouter 作为可选模式?(向后兼容)
