Here are the correct answers to your questions: * To create an AI system that analyzes data, makes decisions, and stores memory * To decide which execution path should be followed * Traffic controller deciding routes * To simplify user interaction and hide system complexity * User Query → Intent → Routing → Analysis/Decision → Memory → Output * It includes routing, tools, agents, and memory * Intent detection and conditional routing * Persistent business decisions stored in a database * Pydantic structured output * Task type (analysis / decision / summary) * Sentiment analysis with urgency * Type safety and predictable structure * RunnableLambda * System switches to summary or safe path * Chain * Understanding what the user wants * Choose execution path based on conditions * task == decision * Mimic departments working simultaneously * Customer and financial analysis * Outputs merged and returned * Chains * Agents are slower and expensive * Training * Conditional chains * Dictionary of outputs * Turns a function into an LLM-callable tool * Prevent unsafe SQL hallucinations * Fetch enterprise data * Acts like normal function * Empty dictionary {} * SQLite table * decision_memory * Persistent and auditable * store_decision_memory * SQL runs inside tools * Only complex decisions * Reason and decide * Record final action * RunnableLambda * Tools require input * Runtime error * groq_llm.py * Load environment variables * SQLite decision memory * Controlled interfaces to systems * Complexity hidden behind chains * Clear responsibility & maintainability * Tool layer * Decision-oriented AI system using LangChain
