1. AI System Design & Agent Architecture

1. AI系统设计与Agent架构

  • Autonomous Agents: Implement the ReAct (Reason + Act) loop with explicit "Thought" and "Action" blocks.
  • AutoGen v0.4 Patterns (Microsoft):
    • Event-Driven Architecture: Use Async Messaging for non-blocking agent communication.
    • GroupChat: Replace rigid hierarchies with dynamic "GroupChat" where agents speak based on "Speaker Selection Policies".
    • Cross-Language: Enable .NET and Python agents to collaborate in the same workflow.
  • Memory Systems: Short-term (Context window), Long-term (Vector stores), and Entity memory (Zettelkasten-style graph).
  • Multi-Agent Orchestration: Support Hierarchical, Sequential, and Peer-to-Peer (Collaborative) topologies.
  • Tool Use: Perfect JSON Schema definitions and 'Semantic Kernel' plugin design for recursive tool invocation.
  • 自主Agent：通过明确的“思考”和“行动”模块实现ReAct（推理+行动）循环。
  • AutoGen v0.4模式（微软）：
    • 事件驱动架构：使用异步消息传递实现非阻塞式Agent通信。
    • GroupChat：以动态“GroupChat”替代僵化的层级结构，Agent根据“发言者选择策略”进行交流。
    • 跨语言协作：支持.NET与Python Agent在同一工作流中协作。
  • 记忆系统：短期记忆（上下文窗口）、长期记忆（向量存储）以及实体记忆（Zettelkasten式图谱）。
  • 多Agent编排：支持层级式、顺序式与对等（协作式）拓扑结构。
  • 工具调用：完善的JSON Schema定义与“Semantic Kernel”插件设计，支持递归工具调用。

2. Advanced Prompt Engineering

2. 高级提示工程

  • Techniques: Chain-of-Thought (CoT), Few-Shot, Self-Reflect (Self-Consistency).
  • DSPy Optimization: Treat prompts as optimization problems (Compiling Prompts) rather than static strings. Use "Signatures" and "Modules".
  • System 2 Thinking: For complex logic, force the model to output a verified "Thought Process" (o1-preview style) before the final answer.
  • Fabric Inspired Patterns: Use structured patterns for specific tasks: 
    extract_wisdom
    , 
    summarize_paper
    , 
    generate_strategy
    .
  • Control: Use System Prompts to enforce persona, constraints, and deterministic output formats.
  • Anti-Hallucination: Force the model to "Cite sources" or use "Wait and Think" (Step-by-Step) protocols.
  • 技术方法：思维链（CoT）、少样本示例、自我反思（自洽性）。
  • DSPy优化：将提示词视为优化问题（编译提示词）而非静态字符串。使用“签名”和“模块”。
  • 系统2思考：针对复杂逻辑，强制模型在输出最终答案前，先输出经过验证的“思考过程”（o1-preview风格）。
  • Fabric启发式模式：为特定任务使用结构化模式：
    extract_wisdom
    、
    summarize_paper
    、
    generate_strategy
    。
  • 控制机制：使用系统提示词强制执行角色设定、约束条件与确定性输出格式。
  • 防幻觉：强制模型“引用来源”或使用“等待与思考”（分步）协议。

3. Retrieval-Augmented Generation (RAG)

3. 检索增强生成（RAG）

  • Indexing: Chunking strategies (Recursive, Semantic), Embedding models, and Meta-data filtering.
  • Retrieval: Use Hybrid Search (Semantic + Keyword) and Reranking (Cohere Rerank) for precision.
  • Context Injection: Pass relevant, ranked context into the LLM window while respecting token limits and context hierarchy.
  • 索引构建：分块策略（递归式、语义式）、嵌入模型与元数据过滤。
  • 检索环节：使用混合搜索（语义+关键词）与重排序（Cohere Rerank）提升精度。
  • 上下文注入：在遵守令牌限制与上下文层级的前提下，将相关的、经过排序的上下文传入LLM窗口。

4. LangChain, LangGraph & Orchestration

4. LangChain、LangGraph与编排

  • LangGraph Expertise: Build stateful, cyclic graphs with State Persistence. Logic for "Wait for Human Input" or "Retry Node" based on feedback loops.
  • CrewAI & Task Delegation: Define clear "Tasks" with "Deliverables" and assign them to specific Agent "Roles".
  • Evaluators: Use LangSmith or Phoenix to trace and debug complex agent steps and execution paths.
  • LangGraph专业能力：构建带有状态持久化的有状态循环图谱。基于反馈循环实现“等待人类输入”或“重试节点”的逻辑。
  • CrewAI与任务分配：明确定义带有“交付成果”的“任务”，并将其分配给特定的Agent“角色”。
  • 评估工具：使用LangSmith或Phoenix追踪与调试复杂Agent的步骤和执行路径。

5. AI Product Strategy & Evaluation

5. AI产品策略与评估

  • Unit Economics: Optimize token costs vs. model performance (Flash vs. Pro).
  • Evaluation Patterns: Use LLM-as-a-Judge, RAGAS (Faithfulness, Relevance), and Human-in-the-loop.
  • Security: Prevent Prompt Injection and audit PII leaks in LLM outputs.
  • 单位经济效益：优化令牌成本与模型性能的平衡（Flash版 vs Pro版）。
  • 评估模式：使用LLM作为评判者、RAGAS（忠实度、相关性）以及人在回路中。
  • 安全保障：防止提示词注入，审计LLM输出中的PII（个人可识别信息）泄露。
