Move beyond prompting to build a Context Engine in a transparent architecture of context and reasoning

Universal Context Engine Blueprint [**🎞️▶️**](https://denis2054.github.io/Context-Engineering-for-Multi-Agent-Systems/media/player.html) **In 21st‑century Agentic AI, Natural‑Language‑Programmed LLMs are the execution agents, and the domain‑agnostic dual‑RAG MAS is the environment they operate in.** This repository provides a production-ready blueprint for the Agentic Era, allowing you to replace rigid, hard-coded workflows with a dynamic, **transparent**, **observable**, and **sovereign** **Context Engine**. By building universal, domain-agnostic Multi-Agent Systems through high-level semantic orchestration, you can save thousands of lines of code while maintaining 100% observability.

About the book

Context Engineering  for Multi-Agent Systems, First Edition Generative AI is powerful, yet often unpredictable. This guide shows you how to turn that unpredictability into reliability by thinking beyond prompts and approaching AI like an architect. At its core is the Context Engine, a glass-box, multi-agent system you’ll learn to design, strengthen, and apply across real-world scenarios. Written by an AI guru and author of various cutting-edge AI books, this book takes you on a hands-on journey from the foundations of context design to building a fully operational Context Engine. Instead of relying on brittle prompts that give only simple instructions, you’ll begin with semantic blueprints that map goals and roles with precision, then orchestrate specialized agents using the Model Context Protocol (MCP). As the engine evolves, you’ll integrate memory and high-fidelity retrieval with citations, implement safeguards against data poisoning and prompt injection, and enforce moderation to keep outputs aligned with policy. You’ll also harden the system into a resilient architecture, then see it pivot seamlessly across domains, from legal compliance to strategic marketing, proving its domain independence. By the end of this book, you’ll be equipped with the skills needed to engineer an adaptable, verifiable architecture you can repurpose across domains and deploy with confidence.

📣 The Live Workshop Session Cohort 2 Takeaways

April 2026 Workshop was a productive move forward ✅ The Levels of Efficient Context · ✅ Dual RAG · ✅ Agent Orchestration · ✅ Compliance & Risk **Stop tinkering with prompts. Start engineering context.** Most AI implementations fail at scale because they rely on black-box prompting — sending a request into the void and hoping for a coherent reply. Following the success of our January session, **Cohort 2** of this hands-on workshop is now open. We move beyond simple instructions to build a Context Engine: a transparent, glass-box architecture where agents don't just guess — they execute a precise, structured plan. The workshop frames the new software stack as a **delegation gradient** across four runtimes — from the human running a context engine in their head, through embedded copilots, configured platforms, and engineered systems. Mastery of the underlying tiers is what makes any of them deployable. We close with the question that sits underneath every enterprise AI decision in 2026: which tier does this problem belong in, and what does compliance actually require? Save thousands of lines of code by building universal, domain-agnostic Multi-Agent Systems (MAS) using the ultimate new programming language: **natural language, engineered as context.** [**🧭 The Tiers of Context Engines — Tier 3 → Tier 2 → Tier 1.5 → Tier 1**](https://denis2054.github.io/Context-Engineering-for-Multi-Agent-Systems/media/three_tier_context_engines.html) [**⚖️ Compliance & Risk Management — GDPR · HIPAA · SOC 2 · ISO · FedRAMP**](https://denis2054.github.io/Context-Engineering-for-Multi-Agent-Systems/media/compliance_risk_management.html)

Requirements for this book

Before running the code, ensure your development environment is properly set up. All hands-on chapters use reproducible Python-based environments, tested in **Google Colab** and **VS Code**. > **A Note on Latency:** The Context Engine built in this book and repository performs complex, multi-step reasoning, not simple, single-shot answers. The delay you observe in Colab is the "thinking" time, as the engine dynamically plans and executes a sequence of API calls (e.g., planning, then RAG, then generation). This is the same reason advanced platforms like Gemini or ChatGPT require a moment to "think" for complex requests, even though they benefit from significantly more powerful environments. ### ✅ Prerequisites - **Python**: Version **3.10+** - **Environment Options:** - Google Colab **or** - Local Python environment with: - `openai` - `pinecone-client` - `tiktoken` - `tenacity` - `fastapi` ### 🚀 Quick Start Get up and running using cloud-based virtual machines using the Google Colab links provided for each notebook. No local installation is required. #### 1. Get Your API Keys Before running the notebooks, you will need valid API keys for the underlying services: * **OpenAI**: Sign up and generate a key at [platform.openai.com](https://platform.openai.com/). * **Pinecone**: Sign up and generate a free API key at [pinecone.io](https://www.pinecone.io/). ### 2. Run the Notebooks Click the badges below to launch the notebooks directly in a pre-configured Google Colab VM. You will be asked to add your API keys to the Colab Secrets Manager upon launch. | Chapter | Notebook | Launch | | :--- | :--- | :--- | | **Chapter 4** | **Context Engine** | [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/YOUR_USERNAME/YOUR_REPO/blob/main/Context_Engine.ipynb) | | **Chapter X** | *Another Notebook* | [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/YOUR_USERNAME/YOUR_REPO/blob/main/FILENAME.ipynb) | ### ✅ Project Structure Create a GitHub or local workspace containing at least: - `helpers.py` - `agents.py` - `registry.py` - `engine.py` - Notebook files for each chapter ### ✅ Required API Keys - **OpenAI** – model access and moderation - **Pinecone** – vector database storage and retrieval - **(Optional)** Google Cloud or AWS – for deployment sections in Chapter 10 ### ✅ System Requirements | Requirement | Minimum | Recommended | |------------|---------|--------------| | CPU | Dual-core | Any modern multi-core | | RAM | 8 GB | 16 GB or Google Colab Pro | | GPU | Optional, but helpful for embeddings and token-heavy operations | > **Note:** From **Chapter 5 onward**, modular components depend on earlier notebooks. Ensure your environment is configured correctly, as setup steps may not be repeated in later chapters. ### ✅ Additional Notes - Local execution may incur **token and API costs** with large contexts. - The **Summarizer Agent** (Chapter 6) helps reduce token usage. - Familiarity with **RAG workflows** and **MCP-based agent orchestration** is recommended. - Refer to **Appendix: Context Engine Reference Guide** for quick lookup of component structures and explanations.

A graduate of Sorbonne University and Paris‑Diderot University, he designed one of the earliest patented *word2matrix* numerical encoding systems which was a precursor to modern embedding techniques. He designed one of the first industrial conversational agents, deployed as an automated language teacher for Moët & Chandon and other global companies. Throughout his career, Denis has built large‑scale AI systems across industries, from IBM resource optimizers to worldwide Advanced Planning and Scheduling (APS) solutions, always focusing on transparent, explainable, and production‑ready architectures. Building on decades of applied AI engineering, he has become a leading voice in the agentic era of AI, authoring influential books on transformers, RAG pipelines, business‑ready generative AI, and now *Context Engineering for Multi‑Agent Systems*. His work emphasizes model‑agnostic engineering, semantic design, and the construction of resilient, domain‑independent AI systems that go far beyond prompting. Denis continues to publish hands‑on frameworks, open‑source architectures, and practical guides that help engineers, researchers, and organizations build the next generation of verifiable, context‑driven AI systems.
