### AI overview

The article explains how large codebases impose a context cost on coding agents when they repeatedly search and reread files. It describes Sonar Vortex and its SemSitter codebase graph, which provides precise nodes and typed relationships to reduce context carried per task, round-trips, and missed call sites during refactoring.
