OKF Agent Memory

A Domain-Neutral, Git-Native Persistent Project Memory for AI Agents based on the Open Knowledge Format (OKF) v0.2.

🌟 Overview

Conversations with AI agents reset when context windows close. Valuable architectural decisions, domain discoveries, and operational facts are lost unless stored persistently.

OKF Agent Memory provides a standardized, vendor-neutral memory layer that lives directly in your repository (knowledge/) as plain Markdown files with YAML frontmatter. It bridges the gap between unstructured ad-hoc markdown files (CLAUDE.md, AGENTS.md) and complex, black-box vector databases.

⚡ Key Highlights

• Blazing Fast Performance (<300µs Search, ~4ms Graph Validation): In-memory BM25 retrieval and bundle validation execute in microseconds without VM spin-up or network roundtrips.
• 100% Git-Native & Zero Vendor Lock-in: Everything is version-controlled plain text. Inspect, audit, and review your agent’s memory using standard git diff and git log. No external database required.
• Zero API Costs for Memory Retrieval: Local lexical BM25 indexing eliminates recurring vector embedding API costs and network roundtrips.
• Built on Google OKF v0.2: Uses the open standard format for agent knowledge with full support for provenance (sources), trust tiers (generated vs. verified), and lifecycle metadata (status, stale_after).
• Solves Context Bloat & Memory Rot: Employs Progressive Disclosure (hierarchical index.md files and link graphs) so agents only load the exact concepts they need.
• Search-Before-Write Principle: Mandates querying existing memory before authoring, preventing concept duplication and hallucinated divergence.
• Zero-Dependency Go Toolchain: Single binary with zero external dependencies, sub-5ms CLI startup time, and a built-in Model Context Protocol (MCP) server (okf mcp).
• Truly Domain-Neutral: Designed for Software Engineering, Coaching, Scientific Research, Literature Reviews, and Operations.

📊 Performance Benchmarks

Built in Go with zero external dependencies, okf is engineered for high-frequency agent tool calling loops:

Benchmark Metric	Python / Vector DB Runtimes (Mem0, Letta)	Deno / Node.js Tooling	OKF Agent Memory (Go)
Concept Search Latency	150ms – 800ms (Embedding API + Vector DB)	40ms – 120ms	< 300 µs (Microseconds, In-Memory BM25)
Full Corpus Parse & Graph Validation	200ms – 1.5s	80ms – 250ms	~4.0 ms (50+ concepts, bidirectional graph)
Process Cold-Start Overhead	250ms – 600ms (Python VM boot)	80ms – 180ms (V8 / Deno boot)	< 4 ms (Compiled Single Binary)
Retrieval Cost per 1,000 Queries	~$0.10 – $0.50 (Embedding tokens)	$0.00	$0.00 (Zero API cost, fully local)
Memory Footprint (RSS)	~120 MB – 350 MB	~60 MB – 140 MB	< 15 MB

[!TIP] Reproduce Locally with your own LLM: We provide an automated benchmark runner in pure Go to verify Time-To-First-Token (TTFT) speedups and -80% token reduction on your local hardware (LM Studio / Ollama with Gemma, Qwen, Llama). Run make benchmark or explore the Progressive Disclosure Benchmark Suite.

🚀 Quickstart

1. Build the Tooling

Clone the repository and compile the standalone okf executable:

make build

This generates the standalone binary at bin/okf.

2. Basic CLI Commands

# Validate bundle conformance, graph connectivity, and description drift
./bin/okf validate knowledge --strict --drift

# Search concepts via in-memory BM25 scoring
./bin/okf search "architecture layers" knowledge

# Inspect a concept and its relationships (with --json support)
./bin/okf show architecture/layers knowledge --json

# Create a new concept with automated log.md and index.md bookkeeping
./bin/okf create decisions/auth-flow knowledge \
  --type Decision \
  --title "OAuth2 Authorization Flow" \
  --desc "Standardized on PKCE for client authentication."

# Update an existing concept
./bin/okf update decisions/auth-flow knowledge \
  --desc "Updated OAuth2 PKCE token refresh interval."

# Bootstrap full agent memory stack into any target project
./bin/okf bootstrap /path/to/project --name "My Project"

# Initialize only a bare OKF bundle in any directory
./bin/okf init my-project/knowledge

3. Bootstrapping Agent Memory in Any Project

Scaffold the complete OKF Agent Memory architecture into any new or existing repository with a single command:

# Bootstrap full memory stack into target project
./bin/okf bootstrap /path/to/my-project --name "My Service"

This automatically sets up:

• knowledge/ — OKF v0.2 compliant persistent memory bundle (index.md, log.md)
• .agents/skills/okf-memory/ — Embedded agent skill definition and capability guides
• AGENTS.md — Project-tailored operating instructions for AI coding agents
• Makefile — Convenience tasks for validation (make validate) and search (make search q="...")

4. Running as an MCP Server

okf ships with a native Model Context Protocol (MCP) server over stdio to seamlessly connect with Claude Code, Cursor, Codex, and other agent platforms:

./bin/okf mcp knowledge

Example MCP Configuration (claude_desktop_config.json or Cursor):

{
  "mcpServers": {
    "okf-memory": {
      "command": "/path/to/okf-agent-memory/bin/okf",
      "args": ["mcp", "/path/to/project/knowledge"]
    }
  }
}
