okf-memory/okf-agent-memory ? reverse-engineered prompt

Build me a Go tool for AI agent memory that keeps project knowledge in git instead of a database.

I want a small command line app that can validate a knowledge bundle, search it fast, show a concept and its links, and create or update entries while keeping the bookkeeping files in sync. It should use a compact OKF style markdown knowledge folder, support progressive disclosure with index files, and make it easy for an agent to look up facts before writing new ones. I also want an embedded MCP server so coding agents can query the memory directly, plus a simple way to check rules for a specific source file before editing it.

Please keep it pure Go, local only, and fast. If you need to look up current OKF or MCP docs online, do that. Make the result feel like a polished developer tool with good error messages, examples, and a clean README.
