GitHub - okf-memory/okf-agent-memory: Git-native persistent memory for AI coding agents. Implements Google OKF v0.2 with sub-300µs in-memory BM25 search, embedded MCP server, and progressive disclosure. Slashes token bloat by 80% with zero external databases or dependencies. Built in pure Go.

OKF Agent Memory is a vendor-neutral, Git-native persistent memory system for AI agents built on Google's Open Knowledge Format (OKF) v0.2. The project, available on GitHub, stores agent knowledge as plain Markdown files with YAML frontmatter inside a repository's knowledge/ directory. A zero-dependency Go CLI provides BM25 search (under 300µs), bundle validation, and a Model Context Protocol server, with no external database or embedding API costs.
