Agent Harness Engineering
Building Systems That Build Systems
The model is a commodity. The harness is the product. Eight lessons on the deterministic infrastructure that makes multi-agent systems reliable in production — context engineering, session spawning, directive routing, till-done semantics, agent memory, multi-agent coordination, and self-healing observability. Every lesson is extracted from a production build session.
