ABP Studio AI Coding Agent addresses this through three harness components: Rules (always-on conventions injected every turn), Skills (on-demand procedural checklists loaded only when relevant), and Lessons (corrections the agent records itself after mistakes). Together they form a persistent knowledge layer that accumulates solution-specific context over time. The post explains the distinction between model, harness, and agent, argues that most AI coding failures are harness gaps rather than model limitations, and provides practical guidance on when to use each mechanism and how to manage context window budget across all three. ## Full article daily.dev links to this article rather than hosting it.
