Skill: Fast Unified Memory

A high-performance unified memory system that integrates OpenClaw memory with semantic memory storage using Ollama's nomic-embed-text model for ultra-fast embeddings.

Overview

This skill provides a unified memory layer that combines:

• OpenClaw Memory: Standard file-based memory storage
• Semantic Memory: Vector-based memory using Ollama embeddings

Features

• ⚡ Ultra-fast: ~130ms for combined search (embedding ~40ms + search ~90ms)
• 🔒 Private: All processing done locally via Ollama
• 💰 Free: No API costs - uses local Ollama instance
• 🧠 Semantic: Uses nomic-embed-text for intelligent similarity matching

Requirements

• Ollama installed and running

• nomic-embed-text

  model pulled:

  ollama pull nomic-embed-text

Installation

# Install Ollama first
curl -fsSL https://ollama.ai/install.sh | sh

# Pull the embedding model
ollama pull nomic-embed-text

# Start Ollama
ollama serve

Usage

Commands

# Search both memory systems
node fast-unified-memory.js search "your query"

# Add a memory
node fast-unified-memory.js add "User prefers concise responses"

# List all memories
node fast-unified-memory.js list

# Show system stats
node fast-unified-memory.js stats

Performance

Metric	Value
Embedding generation	~40ms
Vector search	~50ms
File search	~40ms
Total search	~130ms

Configuration

The skill uses these defaults:

• Ollama URL:

  http://localhost:11434

• Embedding model:

  nomic-embed-text

• Memory storage:

  ~/.mem0/fast-store.json

• OpenClaw memory:

  ~/.openclaw/workspace/memory/

Files

• fast-unified-memory.js

  - Main CLI tool

• SKILL.md

  - This documentation

Troubleshooting

Ollama not running:

ollama serve

Model not found:

ollama pull nomic-embed-text

Port conflict: The skill assumes Ollama is on port 11434. Update the

OLLAMA_URL

constant if using a different port.
