AI agents read code with basic tools, incurring higher token costs

A new article explains how AI agents interact with code differently than human developers. Unlike humans who leverage IDEs for instant navigation and conceptual pattern matching, agents rely on basic tools like grep and glob. This fundamental difference in how agents 'read' code leads to a higher token cost for tasks that humans perform with ease, as agents lack persistent memory and rely on literal pattern recognition. AI
