How projects scale through RAG

When you upload many documents to a project, a question may arise: what happens when context window limits are reached? Projects automatically scale through a feature called Retrieval Augmented Generation, or RAG. When a project's knowledge base approaches the context window limit, Claude smoothly activates RAG mode. Instead of loading all of the project's content into memory at once, Claude intelligently searches and retrieves only the most relevant information needed to answer your questions. This expands your project's capacity up to tenfold while preserving response quality. You will see a visual indicator when your project is operating in RAG mode, but the experience should feel the same: you can still upload documents, converse with Claude, and receive context-aware responses. This allows you to build truly large knowledge bases without worrying about technical limits. The main practical implication: the more precisely you name files, the better Claude finds the right information in RAG mode.
