We built OKF Agent Memory because we were frustrated with how AI coding agents (Claude Code, Cursor, Windsurf, local models) handle long-term project context.

Every time a context window closes or a session resets, the agent forgets architectural decisions, domain discoveries, and operational rules. The existing solutions fall into two extremes: 1. Ad-hoc flat files (CLAUDE.md, AGENTS.md, .cursorrules) that inevitably balloon into 20k-token monoliths, degrade agent focus, and cause "lost-in-the-middle" attention failure. 2. Vector databases / background daemons (Mem0, Letta, Zep) that introduce heavy runtimes (Python/Node), docker containers, proprietary storage silos, and recurring embedding API costs (adding 200–800ms per retrieval call).

Our approach: The "LLM Wiki" in pure Go.

OKF Agent Memory (v0.1.0) is a single, zero-dependency Go binary that turns your Git repository into a structured, self-validating knowledge corpus based on Google's Open Knowledge Format (OKF) v0.2 specification:

• In-Memory BM25 Search (<300µs): Fast lexical ranking across titles, YAML metadata, tags, and bodies directly in memory. No embedding APIs, zero network overhead, zero runtime cost. • Progressive Disclosure: Slashes prompt overhead by up to 90%. Instead of loading thousands of lines of context, the agent searches the bundle index and pulls only the exact 300-token concept required for the current task. • 100% Git-Native: Everything lives in `knowledge/` as human-readable Markdown. You audit your agent's memory via `git diff`, `git blame`, and code reviews. • Built-In Stdio MCP Server: `okf mcp knowledge` exposes native Model Context Protocol tools (`okf_search`, `okf_show`, `okf_create`, `okf_validate`) directly to Claude Code and Cursor. • Trust Tiers: Distinguishes authoritative human law (`verified: human:...`) from agent-generated drafts (`generated: agent:...`). • Sub-4ms Cold Starts (<15MB RSS): Starts in milliseconds with no VM spin-up.

Try it in 30 seconds: $ brew install okf-memory/tap/okf $ cd your-project && okf bootstrap .

We'd love your feedback on the architecture, the Go implementation, and how your coding agents behave with progressive disclosure memory!
