Architecting efficient context-aware multi-agent framework for production- Google Developers Blog

This post introduces a new architectural paradigm for managing agent context, treating it as a compiled view over a stateful system. ADK's tiered model separates storage (Sessions, Memory, Artifacts) from presentation (Working Context), utilizing Flows and processors as a compilation pipeline. Context compaction and filtering are applied at the Session layer to manage long-running conversations, and context caching is optimized by treating context as a stable prefix.
