-# @page-agent/llms
-
-LLM client with a **reflection-before-action** mental model for page-agent.
-
-## Why This Package Exists
-
-The LLM module and the agent logic are inherently coupled. This package exists not to decouple them, but to **define the interface contract** between the LLM and the agent.
-
-The core abstraction is the `MacroToolInput` — a structured output format that **forces the model to reflect before acting**.
-
-## The Reflection-Before-Action Model
-
-Every tool call must first output its reasoning state before the actual action:
-
-```typescript
-interface MacroToolInput {
-  // Reflection (mandatory before any action)
-  evaluation_previous_goal?: string  // How well did the previous action work?
-  memory?: string                     // Key information to remember
-  next_goal?: string                  // What to accomplish next
-
-  // Action (the actual operation)
-  action: Record<string, any>
-}
-```
-
-This design ensures that:
-
-1. **The model evaluates its previous action** before deciding the next step
-2. **Working memory is explicitly maintained** across conversation turns
-3. **Goals are clearly stated**, making the agent's reasoning transparent and debuggable
-
-## Key Components
-
-| Export | Description |
-|--------|-------------|
-| `LLM` | Main LLM client class with retry logic |
-| `MacroToolInput` | The reflection-before-action input schema |
-| `AgentBrain` | Agent's thinking state (eval, memory, goal) |
-| `LLMConfig` | Configuration for LLM connection |
-| `parseLLMConfig` | Parse and apply defaults to config |

- * @topic LLM 与主流程的隔离
- * @reasoning
- * 将 llm 的调用和主流程分开是复杂的，
- * 因为 agent 的 tool call 通常集成在 llm 模块中，而而先得到 llm 返回，然后处理工具调用
- * tools 和 llm 调用的逻辑不可避免地耦合在一起，tool 的执行又和主流程耦合在一起
- * 而 history 的维护和更新逻辑，又必须嵌入多轮 tool call 中
- * @reasoning
- * - 放弃框架提供的自动的多轮调用，每轮调用都由主流程发起
- * - 理想情况下，llm 调用应该获得 structured output，然后由额外的模块触发 tool call，目前模型和框架都无法实现
- * - 当前只能将 llm api 和 本地 tool call 耦合在一起，不关心其中的衔接方式
- * @conclusion
- * - @llm responsibility boundary:
- *   - call llm api with given messages and tools
- *   - invoke tool call and get the result of the tool
- *   - return the result to main loop
- * - @main_loop responsibility boundary:
- *   - maintain all behaviors of an **agent**
- * @conclusion
- * - 这里的 llm 模块不是 agent，只负责一轮 llm 调用和工具调用，无状态

-## 使用说明
-
-### 对于 Agent 开发者
-- 每个页面都包含了详细的状态指示器和反馈信息
-- 错误信息清晰明确，便于 Agent 理解和处理
-- 异步操作都有明确的完成标志
-- 所有交互元素都有适当的可访问性标记
-
-### 对于测试人员
-- 可以按照测试任务逐一验证 Agent 的能力
-- 每个页面都是独立的，可以单独测试
-- 包含了各种真实场景的模拟
-- 错误场景是随机的，确保测试的真实性
-
-### 技术特性
-- 使用 React + TypeScript 构建
-- 响应式设计，支持不同屏幕尺寸
-- 深色模式支持
-- 无需外部依赖，完全自包含
-- 模拟真实的网络延迟和错误
-
-## 扩展建议
-
-如需添加新的测试场景，建议考虑以下方面：
-- 特定行业的业务流程
-- 更复杂的数据可视化交互
-- 多媒体内容处理
-- 实时协作功能
-- 移动端特有的交互模式
-
-每个新页面都应该：
-- 有明确的测试目标
-- 包含多种难度级别的任务
-- 提供清晰的状态反馈
-- 模拟真实的用户场景
