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.

Traditional approaches suffer from two fatal failure modes:

1. The Prompt Monolith: Stuffing all domain knowledge and rules into AGENTS.md or CLAUDE.md creates massive context bloat and causes attention drift (agents ignore critical instructions).
2. The RAG Blindspot: Dumping behavioral rules into vector databases fails because agents never semantically search for operational constraints (e.g. formatting or security rules) during general tasks.

OKF Agent Memory resolves this dilemma with the Dual-Memory Agent Architecture (DMAA):

The Universal Composition Model

In DMAA, every agent configuration is structured by a universal composition:

$$\text{AGENTS.md} = \underbrace{\text{Domain Codex (AAG)}}{\text{Project Invariants, Tone, Guardrails}} + \underbrace{\text{OKF Memory Bridge}}{\text{Standardized Triggers: Search-Before-Write}}$$

• Layer 1: Normative Working Memory (Push Layer): A permanent, ultra-compact behavioral codex (~100–150 tokens) expressed in Agent Action Grammar (AAG). Loaded at session start, enforcing zero-tolerance invariants.
• Layer 2: Semantic Domain Memory (Pull Layer): An OKF v0.2 knowledge bundle (knowledge/) that consumes 0 tokens at baseline and is queried on-demand in microseconds.

⚡ Key Highlights

• Dual-Memory Cognitive Architecture (DMAA): Separates normative push working memory (AGENTS.md codex) from semantic pull domain memory (knowledge/ bundle), completely eliminating prompt bloat.
• Agent Action Grammar (AAG): Ultra-compact, deterministic ASCII micro-syntax saving ~78–85% tokens compared to natural language prompt instructions.
• 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.
• Governance & Code-to-Knowledge Binding: Bind architecture decisions directly to source files via code_refs and query active constraints/holds via --for-path before modifying code.
• 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:

[!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

# Discover constraints and active holds governing a specific source file before editing
./bin/okf search --for-path pkg/okf/types.go 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

# Zero-Knowledge Sync: initialize vault and print Emergency Kit
./bin/okf hub init-vault knowledge

# Zero-Knowledge Sync: push or sync changes with the Hub (optional: --token or OKF_HUB_TOKEN)
./bin/okf hub push knowledge --password "pass" --secret-key "XXXX-..." --auth-token "my-token"
./bin/okf hub sync knowledge --password "pass" --secret-key "XXXX-..."

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"]
    }
  }
}
