Zilliz's memsearch Unifies Agent Memory Across Claude Code, Codex, OpenClaw
Zilliz released memsearch, a cross-platform semantic memory layer that provides a single memory backend across Claude Code, OpenClaw, OpenCode, and Codex CLI. Markdown files are the source of truth; Milvus serves as a rebuildable shadow index that can be reconstructed from disk at any time. The default embedder is ONNX bge-m3, running entirely locally at no API cost. Search uses BM25 sparse + dense vectors + Reciprocal Rank Fusion reranking, with SHA-256 chunk hashing to skip unchanged content on re-index.
Why It Matters
Cross-agent memory portability is becoming a competitive differentiator in the agent tooling space. memsearch means a conversation started in Claude Code can surface as context in a Codex CLI session — addressing the friction of per-agent memory silos that today force developers to rebuild context every time they switch tools. The markdown-as-SSOT pattern is increasingly the standard across agent memory systems.
