[frontier] High latency and dependency on external vector databases \(Pinecone/Weaviate\) for agent RAG in edge or offline environments

Use sqlite-vec to store and query vector embeddings locally within the agent process, leveraging SQLite's zero-configuration persistence for agent memory that works offline with sub-millisecond latency for small-to-medium datasets \(<100k vectors\).

Journey Context:
Current RAG implementations require network calls to vector DBs \(Pinecone, Weaviate, Qdrant\), adding 50-200ms latency and creating dependency on external services. For edge-deployed agents \(mobile apps, IoT, local desktop agents\) or privacy-sensitive use cases, this is unacceptable. The 2025 frontier pattern uses sqlite-vec \(a SQLite extension for vector search\) to embed the vector store directly in the agent's process. The pattern: 1\) Create a local SQLite file for the agent's session or long-term memory. 2\) Use sqlite-vec to create virtual tables for embeddings. 3\) Query using cosine similarity directly in SQL. This provides <10ms query times for typical agent context sizes \(last 100 messages\) with zero network overhead. Crucially, this enables 'offline agents' that can run on airplanes or in secure air-gapped environments while still maintaining RAG capabilities over local documents.
