Context Engineering for Multi-Agent Systems
By :
In this chapter, we elevated the Context Engine from a functional prototype to a pre-production system. By refactoring and rebuilding its architecture, we enforced professional engineering principles that made the engine robust, transparent, and reliable, a practical blueprint for developing resilient multi-agent systems.
The most impactful change was the introduction of dependency injection, which removed reliance on global variables and made every component self-contained and explicitly aware of its dependencies. This decoupled design dramatically improved the engine’s flexibility, testability, and maintainability.
We also hardened each subsystem, from helper functions to agents, by adding structured logging and precise error handling. These upgrades created a fully auditable, fault-tolerant workflow. Finally, we demonstrated how to refactor a monolithic notebook into a modular application, showing how separate library files and clear inter-module communication create...
