Memory Pro

Memory Pro Skill

A highly efficient semantic search engine for your OpenClaw workspace memory, powered by FAISS and Sentence-Transformers.

This skill indexes Markdown files and key agent files (e.g. MEMORY.md, SOUL.md) to provide meaning-based context retrieval instead of exact keyword matching.

🚀 Installation

This skill can be installed on any OpenClaw host.

# Clone or copy the folder
cd memory-pro-export
chmod +x install.sh
./install.sh

The installation script will:

1. Copy the skill to ~/.openclaw/skills/memory-pro
2. Set up a Python virtual environment using uv
3. Configure and start a systemd user service (memory-pro.service)

⚙️ Architecture

• Engine: FAISS + sentence-transformers (all-MiniLM-L6-v2)
• API: FastAPI running on port 8001
• Data Source: Configurable via environment variables (Defaults to ~/.openclaw/workspace/memory/ and MEMORY.md, SOUL.md, etc.)
• Service: Runs safely in the background, rebuilding the index on startup to ensure consistency.

💻 Usage (For Agents)

Use the client script to query the running service.

1. Semantic Search (Recommended)

# Basic search
python ~/.openclaw/skills/memory-pro/scripts/search.py "What did I do yesterday?"

# JSON output (for better tool parsing)
python ~/.openclaw/skills/memory-pro/scripts/search.py "project updates" --json

2. Manual Index Rebuild

The index is automatically rebuilt when the background service restarts. If you need to force an immediate update:

systemctl --user restart memory-pro.service

(Note: Service restart takes ~15-20 seconds to rebuild index and load models. The client script has auto-retry logic.)

🔧 Environment Configuration

The service behavior can be customized by editing ~/.config/systemd/user/memory-pro.service:

• MEMORY_PRO_WORKSPACE_DIR: The root of your workspace (e.g., ~/.openclaw/workspace/)
• MEMORY_PRO_DATA_DIR: Directory containing .md files to index.
• MEMORY_PRO_CORE_FILES: Comma-separated list of core files to always index.
• MEMORY_PRO_PORT: The port for the API (default 8001).

🩺 Troubleshooting

"Connection failed"

• The service might be stopped or restarting.
• Check status: systemctl --user status memory-pro.service
• If restarting, wait 15 seconds. The client script retries automatically for up to 20s.

"Address already in use"

• Port 8001 is taken by a zombie process.
• Fix: kill $(lsof -t -i:8001) then restart service.
