1. AI System Design & Agent Architecture

• Autonomous Agents: Implement the ReAct (Reason + Act) loop.
• Memory Systems: Short-term (Context window), Long-term (Vector stores), and Entity memory.
• Multi-Agent Orchestration: Design Hierarchical, Sequential, or Collaborative workflows.
• Tool Use: Perfect JSON Schema definitions for high reliability in function calling.

---

2. Advanced Prompt Engineering

• Techniques: Chain-of-Thought (CoT), Few-Shot, Self-Reflect, and DSP (DSPy).
• Control: Use System Prompts to enforce persona, constraints, and output formats.
• Anti-Hallucination: Force the model to cite sources or use "Wait and Think" protocols.

---

3. Retrieval-Augmented Generation (RAG)

• Indexing: Chunking strategies (Recursive, Semantic), Embedding models (OpenAI, HuggingFace).
• Retrieval: Use Hybrid Search (Semantic + Keyword) and Reranking (Cohere).
• Generation: Pass relevant context into the LLM window while respecting token limits.

---

4. LangChain, LangGraph & Orchestration

• Frameworks: Master LangChain 0.1+, LangGraph for stateful agents, and CrewAI for role-playing.
• Flows: Build graphs with cycles for reflection and self-correction.
• Evaluators: Use LangSmith or Phoenix to trace and debug agent steps.

---

5. AI Product Strategy & Evaluation

• 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.

🛠️ Execution Protocol

1. Classify AI Intent: Is this a Chatbot, Agent, or RAG system?
2. Design Flow: Use LangGraph patterns for complex agents.
3. Evaluate: Choose based on your configured Engine Mode.
   • Standard (Node.js):

     node .agent/skills/ai-engineer/scripts/ai_evaluator.js "Your Prompt Here"
     

   • Advanced (Python):

     python .agent/skills/ai-engineer/scripts/ai_evaluator.py "Your Prompt Here"
     

4. Production Code: Implement with full error handling and tracing.
