Welcome to Agentic Harness Engineering: Harness Design for AI Engineers, the definitive, production-grade masterclass for developers ready to build the infrastructure that makes artificial intelligence truly useful. As Vivek Trivedy of LangChain noted, “The model contains the intelligence. The harness is the system that mFikayo Adepojuakes that intelligence useful.” While most developers are stuck building fragile, prompt-dependent wrappers, this course focuses on the system design discipline of agent engineering—teaching you how to design, build, and optimize a custom agent harness from scratch.
Through a rigorous, step-by-step curriculum, you will incrementally build a complete, production-ready infrastructure layer from scratch using Python and Docker. You’ll start by constructing a robust conversation skeleton and a secure filesystem layer using a versioned Git workspace and custom memory patterns. From there, you will escalate to creating a secure code execution engine inside isolated Docker sandboxes, incorporating advanced self-verification test loops and network isolation.
