## AI overview

This article explains context layers for AI-driven software development. A context layer consolidates continuously updated information about services, ownership, dependencies, runtime state, permissions, and organizational relationships so agents can query one accurate model instead of repeatedly combining data from separate tools and APIs. It discusses what to include, whether to build or buy, possible uses, return on investment, measurement, and implementation, while reporting an 80% reduction in per-query agent cost in Port's measurements.
