The Era of the Chatbot is Over. The Era of the Agent has Begun.
Stop asking LLMs to summarize text. Start building Reasoning Engines that plan, execute, and self-correct. This book bridges the gap between passive “Prompt Engineering” and active “Agentic Engineering”. It takes you from your very first API call to a monumental finale: building Sovereign, Air-Gapped Systems that run offline and manage themselves.
What you will build:
- The Cognitive Architecture: Stop guessing. Master the OODA Loop (Observe-Orient-Decide-Act). Learn to architect the Brain (LLM), Body (Tools), Memory (Vector Stores), and Planner to create systems that can “think” before they act.
- Tool Use & Function Calling: Break the text barrier. Build agents that can browse the live web, read PDF resumes, analyze CSV data, and send real emails—turning the AI into a true digital worker.
- Multi-Agent Orchestration: One agent is a worker; a team is a company. Master CrewAI to manage squads of agents (Managers, Researchers, Writers) that collaborate, supervise, and hand off tasks autonomously.
- The “Ironclad” Protocol: Build for the real world. Implement Retry Logic, Circuit Breakers, and Hallucination Guardrails to ensure your agents are robust, reliable, and production-ready.
- On-Device AI & Sovereignty: Cut the cord. Learn to deploy Air-Gapped Agents using Ollama and Docker, allowing you to run private, secure AI models entirely on your local hardware.
Master the professional stack:
- Core: Python 3.14+, VS Code, Git, Docker
- AI Models: Google Gemini, OpenAI, Groq, Ollama (for offline open-source models like Llama 3)
- Agent frameworks: CrewAI, Google GenAI SDK, Tenacity (Retry Logic)
- Memory & data: ChromaDB (Vector Store), Pandas, Pydantic, JSON, Tabulate
- Web integration: FastAPI, BeautifulSoup, DuckDuckGo Search, Uvicorn, Requests, IMAP, SMTP, Streamlit
- File Handling & Utilities: PyPDF2, Python-Dotenv, Rich, Pytest
