🧠 m2-memory

Semantic memory on steroids for OpenClaw agents.

"What did the user prefer?" → Finds it even if you never said "prefer"

---

🚀 Why This Exists

Traditional agent memory = grep through markdown files.

m2-memory = semantic understanding + vector search + importance decay.

You Ask	Markdown Search	m2-memory
"what does master like?"	❌ No match	✅ "Master prefers minimal communication"
"deployment setup"	⚠️ Weak match	✅ "Docker container via Coolify"
"name origin"	❌ No match	✅ "m2 = machine-machine"

📊 Benchmarks

Speed vs Relevance

Method	Latency	Semantic Understanding	Exact Match
Grep/Regex	0.1ms ⚡	❌ None	✅ Perfect
Keyword Search	0.2ms ⚡	⚠️ Weak	✅ Good
m2-memory (dense)	70ms	✅ Excellent	⚠️ Weak
m2-memory (hybrid)	95ms	✅ Excellent	✅ Good

Real Query Results

Query: "what does the user prefer?"

📊 VECTOR SEARCH
   [0.504] Master prefers minimal communication... ✅ CORRECT

📄 MARKDOWN SEARCH  
   [0.20] About Master: Location Poland...       ❌ WRONG SECTION

Hybrid Search Magic

Query: "coolify machinemachine"

[0.862] Coolify running at cool.machinemachine.ai
        ├─ dense score:   0.803 (semantic match)
        └─ keyword score: 1.000 (exact terms)

✨ Features

🔍 Semantic Search

Find memories by meaning, not just keywords.

📝 Auto-Ingest Conversations

python3 scripts/conversation_ingest.py turn "Important decision made" --role user

🔄 MEMORY.md Sync

# Import existing memories
python3 scripts/memory_sync.py import MEMORY.md

# Export back to markdown (human-readable backup)
python3 scripts/memory_sync.py export memories_export.md

🎯 Hybrid Search

Dense embeddings + keyword matching = best of both worlds.

python3 scripts/hybrid_search.py "error code 0x123" --mode hybrid

📊 Importance Scoring

Memories decay over time. Important stuff stays. Noise fades.

🛠️ Quick Start

1. Install

# Copy to OpenClaw skills
cp -r openclaw-m2-memory-skill ~/.openclaw/skills/m2-memory

2. Store a Memory

python3 scripts/memory_client.py store "User loves cyberpunk aesthetics" \
  --importance 0.9 \
  --entities "user,preferences,design"

3. Search

python3 scripts/memory_client.py search "what style does the user like?"
# → [0.78] User loves cyberpunk aesthetics

4. Benchmark Against Markdown

python3 scripts/benchmark.py "query" --markdown MEMORY.md
