This repository implements a persistent memory server for AI agents, designed to solve the problem of agent amnesia across sessions, devices, and team members. The production system is a Rust-based HTTP server (Axum) that exposes a RESTful API with 48+ endpoints, backed by LanceDB for vector storage and supporting both hosted and self-hosted deployments. It ingests conversational or document data via an LLM-powered pipeline that extracts atomic facts, filters noise, scores admission, and reconciles with existing memories using seven operations (CREATE, MERGE, SUPERSEDE, etc.). The system manages a full memory lifecycle with Weibull decay, tier-based promotion/demotion, and auto-forgetting, and provides a multi-stage retrieval pipeline that combines vector search, BM25, cross-encoder reranking, decay boosting, and MMR diversity. Plugins for Claude Code, OpenCode, OpenClaw, and MCP allow client-side integration, and a GitHub connector ingests commits, issues, and PRs as memories. The architecture is multi-tenant with personal, team, and organization spaces, each isolated in separate LanceDB directories, and supports versioned, provenance-tracked sharing with staleness detection.
This is a production-grade long-term memory plugin for the OpenClaw AI agent platform, built as a TypeScript/ESM module. It provides a complete memory lifecycle: LLM-powered extraction from conversation transcripts (6-category classification with L0/L1/L2 layering), hybrid vector+BM25 retrieval with cross-encoder reranking, Weibull decay-based importance scoring, tier management (core/working/peripheral), and multi-scope isolation (global, agent, user, project). The plugin integrates deeply into OpenClaw via lifecycle hooks, agent tools, CLI commands, and a dreaming engine for periodic consolidation. It stores all data in LanceDB and supports multiple embedding providers, LLM backends, and OAuth flows. The codebase is large and complex, with extensive test coverage (100+ tests) and many edge-case handlers, but exhibits significant technical debt in a single massive index.ts file and multiple fallback/legacy migration paths. It is not a research project; it is a highly functional, actively maintained plugin with a clear engineering focus on correctness, resilience, and performance.
This repository is a comprehensive collection of examples, tutorials, and applications demonstrating how to use LanceDB (a vector database) for various AI/ML applications. It showcases patterns for retrieval-augmented generation (RAG), multimodal search, chatbots, recommendation systems, and AI agents. The repository contains both Python and JavaScript/TypeScript implementations, with many examples featuring web interfaces using Streamlit, Gradio, or React. While it serves as a valuable resource for learning LanceDB integration patterns, the quality varies across examples, and some content is marked as archived.
