Beyond Chat: Agentic Prompting
The era of the "Chatbot" is ending. The era of the Agent has begun. A chatbot answers your question. An agent does your work.
The ReAct Pattern
The fundamental loop of an agent is ReAct (Reason + Act):
- Thought: "The user wants to book a flight to Paris. I need to check prices first."
- Action:
call_tool("flight_search", { destination: "CDG" }) - Observation: "Flight AF123 is $800."
- Thought: "That's within the budget. I will book it."
- Action:
call_tool("book_flight", { flight_id: "AF123" })
Tool Use & Function Calling
LLMs are no longer just text generators; they are API Orchestrators.
- We define tools using JSON schemas (OpenAPI).
- The model outputs structured JSON to call these tools.
- This allows AI to interact with the real world: sending emails, querying databases, controlling smart homes.
Long-Term Memory
Chatbots have "context windows" (short-term memory). Agents need Long-Term Memory.
- Vector Databases (RAG): Storing past interactions and relevant documents as embeddings.
- Reflection: Agents that review their past actions to learn and improve ("I failed to find the file last time because I didn't check the archived folder. I will check there next time.").
Multi-Agent Systems
Complex tasks are solved not by one super-smart agent, but by a team of specialized agents.
- The Planner: Breaks the goal into subtasks.
- The Coder: Writes the script.
- The Reviewer: Checks the code for bugs.
- The Executor: Runs the code.
Frameworks like LangGraph and CrewAI are making this orchestration standard practice.
