└─────────────────┘ └─────────────────┘ │ +│ 后端服务 │ +└─────────────────────────────────────────────────────────────────────┘ +``` + +## 二、版本切换机制 + +### 2.1 后端配置 + +在 App 配置中新增 `agent_version` 字段： + +```python +# GptsApp 模型新增字段 +class GptsApp: + app_code: str + app_name: str + agent_version: str = "v1" # 新增: "v1" 或 "v2" + # ... 其他字段 +``` + +### 2.2 前端自动检测 + +```typescript +// 自动检测版本 +function detectVersion(config: ChatConfig): AgentVersion { + // 1. 优先使用配置 + if (config.agent_version) return config.agent_version; + + // 2. 根据 app_code 前缀 + if (config.app_code?.startsWith('v2_')) return 'v2'; + + // 3. 默认 V1 + return 'v1'; +} +``` + +## 三、前端使用方式 + +### 3.1 方式一：使用统一 Chat 服务 (推荐) + +```tsx +import { getChatService } from '@/services/unified-chat'; + +const chatService = getChatService(); + +// 发送消息 - 自动切换版本 +await chatService.sendMessage( + { + app_code: 'my_app', + agent_version: 'v2', // 可选，不填自动检测 + conv_uid: 'xxx', + user_input: '你好', + }, + { + onMessage: (msg)

+chatService.abort(); +``` + +### 3.2 方式二：直接使用 V2 组件 + +```tsx +import V2Chat from '@/components/v2-chat'; + + console.log('Session:', id)} +/> +``` + +### 3.3 方式三：在现有页面集成 + +修改 `chat-context.tsx`： + +```tsx +import { getChatService } from '@/services/unified-chat'; + +// 在 ChatContextProvider 中添加 +const chatService = getChatService(); + +// 修改发送消息逻辑 +const sendMessage = async (input: string) => { + await chatService.sendMessage( + { + app_code: currentDialogInfo.app_code, + agent_version: currentDialogInfo.agent_version, // 新增 + conv_uid: chatId, + user_input: input, + }, + { + onMessage: (msg) => { /* 更新 UI */ }, + onChunk: (chunk) => { /* V2 特殊渲染 */ }, + onDone: () => { /* 完成 */ }, + } + ); +}; +``` + +## 四、应用构建集成 + +### 4.1 后端修改 + +修改 `CreateAppParams`: + +```python +class CreateAppParams: + app_name: str + team_mode: str + agent_version: str = "v1" # 新增 + # ... +``` + +### 4.2 前端应用构建页面 + +新增版本选择： + +```tsx + + + + V1 (经典版) + 稳定的 PDCA Agent + + + V2 (Core_v2) + 新版架构，支持 Canvas 可视化 + + + +``` + +## 五、文件清单 + +### 5.1 后端新增/修改文件 + +``` +packages/derisk-core/src/derisk/agent/ +├── core_v2/ # Core_v2 核心 +│ └── integration/ # 集成层 +│ ├── adapter.py +│ ├── runtime.py +│ ├──

V2AgentRuntime → V2PDCAAgent → Tool/Gateway + → Canvas + Progress → GptsMemory + → SSE Stream → 前端渲染 (支持 Canvas Block) +``` + +## 七、启动方式 + +### 7.1 后端启动 + +```bash +# 方式一：作为现有服务的一部分 +# Core_v2 组件会在服务启动时自动初始化 + +# 方式二：独立启动 V2 服务 +cd packages/derisk-serve +python start_v2_agent.py --api +``` + +### 7.2 前端启动 + +```bash +cd web +npm run dev + +# 访问 V2 Agent 页面 +# http://localhost:3000/v2-agent +``` + +## 八、API 对比 + +| 功能 | V1 API | V2 API | +|-----|--------|--------| +| 创建会话 | 隐式创建 | POST /api/v2/session | +| 发送消息 | POST /api/v1/chat/completions | POST /api/v2/chat (SSE) | +| 获取状态 | - | GET /api/v2/status | +| 关闭会话 | - | DELETE /api/v2/session/{id} | + +## 九、迁移指南 + +### 9.1 从 V1 迁移到 V2 + +1. **后端**: 在 App 配置中设置 `agent_version = "v2"` +2. **前端**: 无需修改，统一服务自动切换 +3. **测试**: 验证消息流和 Canvas 渲染 + +### 9.2 兼容性 + +- V1 和 V2 可以共存 +- 同一会话应使用同一版本 +- 历史数据通过 conv_uid 继承 + +## 十、调试 + +```typescript +// 前端调试 +localStorage.setItem('debug', 'v2-chat:*'); + +// 查看当前版本 +console.log(chatService.getVersion()); +``` + +```python +# 后端调试 +import logging +logging.getLogger("derisk.agent.core_v2").setLevel(logging.DEBUG) +``` diff --git a/VIS_COMPLETE_REPORT.md

可以识别并保护代码块、思维链、文件路径等关键内容 +- **原子组感知**: `_select_messages_to_compact()` 已经实现了 tool-call 原子组保护逻辑 +- **关键信息提取**: KeyInfoExtractor 能自动识别重要性高的信息并优先保留 +- **自适应触发**: 基于 token 增长率的自适应触发策略比简单阈值更智能 +- **兼容两种消息格式**: 已同时处理 `msg.tool_calls` 和 `msg.context.get("tool_calls")` + +相比之下，v1 的 `SessionCompaction`（503 行）功能更简单，缺少内容保护和关键信息提取。 + +### 9.2 为什么采用章节化归档而非仅保留总结？ + +仅保留总结（lossy compression）会导致细节不可逆丢失。在 SRE/RCA 场景中，Agent 经常需要回顾之前读取的日志片段、配置文件内容、执行结果等。 + +章节化归档的优势： +- **可逆性**: 原始消息完整保存在 AgentFileSystem 中，Agent 可随时加载回来 +- **按需加载**: 仅在需要时通过工具加载，不占用常驻上下文 +- **可搜索**: 通过章节总结和关键词可快速定位相关信息 +- **空间效率**: 利用已有的 AgentFileSystem 存储体系，支持 OSS 等远程存储 + +### 9.3 为什么使用适配器模式而非修改 AgentMessage？ + +v1 和 v2 的 `AgentMessage` 在整个系统中被深度使用： + +- v1 `AgentMessage` (dataclass) 被 `ConversableAgent`, `Agent`, `ActionOutput`, `GptsMemory` 等数十个类引用 +- v2 `AgentMessage` (Pydantic BaseModel) 被 `AgentBase`, `BaseBuiltinAgent`, `EnhancedAgent` 等使用 + +直接修改基类会导致： +- 大量已有代码需要适配 +- 序列化/反序列化格式变化的兼容性风险 +- 两个版本之间的依赖混乱 + +适配器模式的优势： +- 零侵入：不修改任何现有类 +- 单点维护：格式差异集中在适配器中处理 +- 安全：任何错误只影响新功能，不影响现有逻辑 + +### 9.4 为什么坚持使用 AgentFileSystem V3 作为存储后端？ + +`AgentFileSystem` V3 已经在 v1 架构中得到充分验证： + +- **统一接口**: 一套 API 支持本地存储和 OSS 远程存储 +- **元数据追踪**: 通过 `FileMetadataStorage` 记录每个文件的完整元数据 +- **会话隔离**: 按 `conv_id` 隔离文件，避免跨会话污染 +- **文件恢复**: 支持通过 `sync_workspace()` 从远程恢复文件 +- **已有集成**: v1 的 Truncator, WorkLogManager 已经使用它 + +将同一套存储体系引入 v2 可以： +- 共享文件管理基础设施 +- 实现跨架构的文件互通 +- 避免重复造轮子 + +### 9.5 为什么设计三层而非两层或一层？ + +三层压缩对应三种不同粒度的内存管理需求： + +| 层 | 粒度 | 触发频率 | 作用 | +|---|---|---|---| +| Layer 1 截断 | 单次工具输出 | 每次工具调用 | 防止单次输出撑爆上下文 | +| Layer 2 剪枝 | 消息级别 | 每 N 轮 | 渐进式释放旧内容空间 | +| Layer 3 归档 | 会话级别 | Token 接近上限 | 大规模压缩 + 持久化 | + +如果只有 Layer 3，在长对话中会出现： +- 前期：大量冗余的旧工具输出占据上下文 +- 触发压缩时：需要一次性压缩大量消息，延迟高 +- 压缩后：丢失大量中间细节 + +三层设计的渐进式策略确保上下文始终保持健康状态。 + +--- +

search_history, get_tool_call_history, get_history_overview）仅在首次 compaction 发生后才动态注入到 Agent 的工具集中。通过 `pipeline.has_compacted` 属性控制。这避免了在短会话中暴露无意义的空工具。 + +2. **v1 Core `all_tool_message` 修正**: v1 架构的 `thinking()` 方法已重写，确保传递给 LLM 的 `tool_messages`（即 kwargs 中的 `all_tool_message`）来自压缩后的记忆（经过 Layer 2 剪枝 + Layer 3 压缩），而非原始未压缩的消息列表。 + +3. **FunctionTool 构造方式**: 使用 `FunctionTool(name=..., func=..., description=...)` 直接构造，而非 `FunctionTool.from_function()`。内部函数引用通过 `_func` 属性访问。 + +4. **v2 工具注册方式**: v2 使用 `ToolRegistry.register_function(name, description, func, parameters)` 注册历史工具，该方法内部创建兼容的 `ToolBase` 包装器。 + +5. **适配器模式**: `UnifiedMessageAdapter` 通过静态方法统一读取 v1 (dataclass)、v2 (Pydantic) 和 plain dict 三种消息格式，不修改任何现有 AgentMessage 类。角色名通过 `_ROLE_ALIASES` 归一化（ai→assistant, human→user）。 + +7. **Skill 保护机制**: 在 Layer 2 (Prune) 阶段，通过 `prune_protected_tools=("skill",)` 配置项，保护 skill 工具输出不被剪枝。在 Layer 3 (Compaction) 阶段，skill 输出被提取到 `chapter.skill_outputs` 并在摘要消息中重新注入，确保 compaction 后 Agent 仍能访问完整的 skill 指令。 + +8. **向后兼容**: 所有新参数默认关闭 (`enable_compaction_pipeline=False`)，`fallback_to_legacy=True` 确保 pipeline 异常时自动回退到现有逻辑。 + +### 测试覆盖 + +- **UnifiedMessageAdapter**: 35+ 测试 —
