claw-mem: Three-Tier Memory System
Local-first memory system with three memory layers and intelligent retrieval.
Prerequisites
pip3 install git+https://github.com/opensourceclaw/claw-mem.git
Quick Start
Search Memory
python3 {baseDir}/scripts/search.py "project deadlines" --limit 10
Store Memory
python3 {baseDir}/scripts/store.py "User preference" --category preference
Start Bridge (for OpenClaw integration)
python3 {baseDir}/scripts/bridge.py --workspace ~/.openclaw/workspace
Memory Layers
| Layer | Purpose | Example |
|---|---|---|
| Episodic | Event sequences | Session context |
| Semantic | Knowledge facts | User preferences |
| Procedural | Rules | Best practices |
Retrieval Modes
| Mode | Description | Use Case |
|---|---|---|
keyword |
Simple keyword match | Quick lookup |
bm25 |
BM25 ranking | Relevance ranking |
hybrid |
BM25 + Keyword | Balanced retrieval |
enhanced_smart |
Full pipeline | Best quality |
Set mode via environment:
export CLAW_MEM_SEARCH_MODE=enhanced_smart
Configuration
