System Design for Agent Systems: Tools, Memory, and Evaluation
kmeanskaran · x · 2026-08-20
This article details the system design for agent systems, arguing that placing a frontier model in a poorly designed system results in articulate failure. It emphasizes that most engineering effort lies outside the model, in the "agent harness." The post covers five essential components: Tools, Prompts, Memory, Orchestration, and Human-in-the-loop. It also highlights the need for distinct evaluation frameworks, as agent systems are not testable like ordinary code.
