Bounded Context

Part 1: Context Engineering — Domain-Driven Design for AI Agents

Answer-first: Applying Domain-Driven Design principles to Context Engineering partitions large enterprise codebases into isolated Bounded Contexts, preventing Large Language Model attentional decay and context window poisoning through scoped Abstract Syntax Tree (AST) extraction and dependency subgraphs, substantially improving the structural precision of AI-generated microservice code and eliminating dangerous cross-domain data leakage across distributed systems. Prerequisite: Familiarity with Domain-Driven Design (DDD) strategic design patterns, Bounded Contexts, and microservice boundary definition. ...
