A new open-source tool called Writ uses a hybrid retrieval pipeline with BM25, ONNX vectors, and Neo4j graph traversals to provide context rules for AI coding agents, reducing token bloat by 726x and enforcing plan approval via bash hooks.
A detailed architectural guide for building long-running AI agents that handle changing user preferences over time by combining a vector store, graph DB, and temporal edges instead of overwriting data.
A user shares a custom harness for Claude Code that uses RAG with a graph database and bash script hooks to prevent context stuffing, saving tokens.
pgGraph is a high-performance, open-source graph traversal extension for PostgreSQL, written in Rust, designed to give AI agents fast relationship queries without migrating data to a separate graph database.
HelixDB is a new open-source database built in Rust that combines vector, graph, and other data models into a single engine, backed by Y Combinator. It aims to replace separate vector, graph, and application databases for AI stacks, offering native vector search, graph traversal, and MCP support.
The article promotes a custom-built 3D knowledge graph tool inspired by Andrej Karpathy, claiming to surpass standard note-taking apps like Notion and Obsidian by creating a persistent, AI-connected 'second brain'.
Codemix open-sources @codemix/graph, a type-safe, CRDT-backed graph database with TypeScript-native schema validation and realtime offline-first sync via Yjs.
