AI Harness Engineering

Tell your AI teacher what agent you want to build, and build it together, lesson by lesson: the loop, tools, MCP, context, prompts, memory, helper agents, safety, testing, skills, hooks, self-checking, streaming and production. You do not write code. Your teacher writes it, and explains every part.
