memsearch

Cross-platform semantic memory for AI coding agents.

📰 What's New

- Optional Jev reranking — rerank memory search results with Jev through the TypeSafe API, with no local model download. See configuration and the Chinese/English evaluation.

- DeepSeek Harness support — MemSearch now brings automatic capture, recall hints, native skill-based recall, background maintenance, and a read-only memory browser to DeepSeek Harness (DSH).
- Skills from memory — MemSearch now distills the workflows you repeat into reusable, installable agent skills (a third "procedural memory" layer) and keeps them up to date in the background. See Skills from Memory.
- Advanced memory maintenance — optional background tasks keep durable PROJECT.md and USER.md notes current across sessions. See Advanced Memory Maintenance.

Why memsearch?

- 🌐 All Platforms, One Memory — memories flow across Claude Code, Codex, DeepSeek Harness, OpenClaw, and OpenCode. A conversation in one agent becomes searchable context in all others — no extra setup
- 👥 For Agent Users, install a plugin and get persistent memory with zero effort; for Agent Developers, use the full CLI and Python API to build memory and harness engineering into your own agents
- 📄 Markdown is the source of truth — inspired by OpenClaw. Your memories are just .md files — human-readable, editable, version-controllable. Milvus is a "shadow index": a derived, rebuildable cache
- 🔍 Progressive retrieval, hybrid search, smart dedup, live sync — 3-layer recall (search → expand → transcript); dense vector + BM25 sparse + RRF reranking; SHA-256 content hashing skips unchanged content; file watcher auto-indexes in real time

How plugins work

A plugin bundles slash commands, subagents, skills, hooks, MCP servers and status lines so they install together.
Add the marketplace inside Claude Code with /plugin marketplace add zilliztech/memsearch, then run /plugin to pick what to install.
You can turn a plugin off again from /plugin without deleting anything.
