兼容的 ChatModel 实现，可以直接替换现有的 `github.com/sashabaranov/go-openai`。 + +**Q: Redis 是必须的吗?** +A: 不是。Redis 是可选的缓存层，未配置时会降级到纯 SQLite 模式，性能略有下降但功能完整。 + +**Q: 如何回滚到旧实现?** +A: 通过配置项 `agent.use_eino: false` 即可切换回旧实现（需要在阶段三保留旧代码）。 + +**Q: 向量检索是否必须?** +A: 不是。可以只使用 FTS5 全文检索，向量检索是可选的增强功能（需要 sqlite-vec 扩展）。 + +**Q: 现有的 MCP Server 需要改造吗?** +A: 不需要。MCP Server 保持不变，只需要通过 Adapter 包装为 Eino Tool。 + +--- + +## 16.

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 实现了完整的 Eino Agent 系统，包括： ## 核心组件 - Stream Handler: 流式对话处理器，支持多轮工具调用 - Agent Orchestrator: 简化版编排器（完整 Graph 实现留待未来） - MCP Tool Adapter: MCP 工具适配到 Eino Tool 接口 - Agent 初始化系统: 统一的启动和配置管理 ## Redis 支持 - 在配置文件中添加 Redis 连接配置 - Memory Manager 自动使用 Redis 作为 L1 缓存（如果启用） - 优雅降级：Redis 不可用时回退到纯 SQLite 模式 ## 集成点 - 在应用启动时自动初始化 Agent 系统 - 全局 Agent 实例可供 HTTP 服务使用 - 与现有 MCP Server 完美集成 ## 技术细节 - 使用 Eino ChatModel 进行 LLM 调用 - 支持流式输出到 IM 客户端 - 工具调用支持多次迭代（最多 10 轮） - QA 缓存、对话历史、用户上下文完整支持 🤖 Generated with [Claude Code](https://claude.com/claude-code)

StreamHandler 替换旧的 llm.Client - Agent 内部已处理消息保存，移除重复保存逻辑 - 保留会话标题生成和时间更新逻辑 - 会话标题生成也切换为使用 Agent ## 钉钉机器人 (DingTalk Stream Mode) - 使用新的 Agent 系统替换旧的 llm.Client - 移除 LLM 客户端初始化代码 - 重写消息处理流程使用 processAgentMessage - 简化代码逻辑，Agent 统一处理消息保存 ## 优点 - 统一的对话处理逻辑 - 自动支持 MCP 工具调用 - 多轮推理能力 - QA 缓存和知识库检索 - Redis 缓存支持（如果启用） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By:

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **问题**: Agent 初始化时只从 config.yaml 读取 LLM 配置， 忽略了数据库 llm_configs 表中的配置，导致用户在 Web UI 中配置的 LLM 无法生效。 **修复**: - 在 initializeStreamHandler 中优先从数据库读取配置 - 使用 ConfigService.GetDefaultLLMConfig() 获取第一个启用的配置 - 如果数据库没有启用的配置，回退到 config.yaml - 增加日志输出，明确显示使用的配置来源 **配置优先级**: 1. 数据库 llm_configs 表（第一个 enabled=true 的记录） 2. config.yaml 中的 llm 配置（回退方案） **日志示例**: ``` 📦 Using LLM config from database: provider=openai, model=gpt-4, base_url=https://api.example.com ``` 或 ``` 📦 Using LLM config from config.yaml: model=gpt-3.5-turbo,

Content-Transfer-Encoding: 8bit **问题**: 之前的错误响应（如 LLM 超时）也会被缓存，导致修复问题后 仍然返回缓存的错误信息，用户体验很差。 **解决方案**: 1. **错误检测** - 在保存缓存前检测答案质量 - 检测错误关键词：❌、失败、错误、timeout 等 - 检测答案长度（<10字符的不缓存） - 错误响应不会被保存到缓存 2. **缓存清理** - 提供手动清理工具 - ClearQACache(username, questionHash) - 清理特定缓存 - ClearErrorCache() - 批量清理所有错误缓存 - 同时清理 SQLite 和 Redis 3. **调试优化** - 增加日志 - 缓存保存时记录 question_hash - 跳过错误响应时输出 debug 日志 **错误关键词列表**: - ❌, LLM 调用失败, Agent 调用失败 - i/o timeout, connection refused, dial tcp - error:, Error:, 失败:, 错误:, 异常: **使用示例**: ```go // 手动清理特定缓存 memoryMgr.ClearQACache("user1", "abc123") // 清理所有错误缓存 count, _ :=
