--- name: graph-rag-memory description: > Graph-RAG memory system using Graphiti temporal knowledge graph + FalkorDB + local Ollama embeddings. Provides persistent, queryable long-term memory for OpenClaw agents via a MoE-style (Mixture-of-Experts) multi-embedding router. Use when: setting up persistent agent memory, querying past conversations or facts, ingesting documents into the memory graph, checking memory system status, or integrating graph-rag memory into an OpenClaw agent. Triggers on: "memory system", "graph rag", "graphiti", "persistent memory", "ingest memory", "query memory", "what do you remember", "memory upgrade". --- # Graph-RAG Memory Skill Persistent, queryable agent memory via a temporal knowledge graph. Facts are extracted from episodes (conversations, documents, notes), stored as typed entities and relationships in FalkorDB, and retrieved via hybrid BM25 + cosine similarity search with domain-expert routing. ## Architecture Overview ``` Write path: content → DomainRouter → expert embedder → Graphiti.add_episode() ↓ FalkorDB (workspace graph) 39+ nodes, 73+ RELATES_TO edges fact_embedding: 768-dim cosine index Read path: query → DomainRouter → expert embedder → query_vector ↓ graphiti_search() [BM25 + cosine RRF] ↓ ranked EntityEdge objects with .fact ``` **Routing layers:** 1. Hard routing (metadata/source_type → domain, confidence=1.0) 2. Centroid routing (cosine similarity to domain centroids, threshold=0.02) 3. Fanout fallback (parallel expert queries + RRF fusion) **Domains:** `personal`, `episodic`, `project`, `technical`, `research`, `meta`, `general` ## Prerequisites See `references/setup.md` for full installation and environment details. **Quick check:** ```python # Verify services (write to a temp script, don't use python3 -c inline) import falkordb, httpx r = falkordb.FalkorDB(host='172.18.0.1', port=6379) print("FalkorDB OK:", r.list_graphs()) # nomic-embed-text must be loaded on NVIDIA Ollama ``` **Python packages** (reinstall after container restart — ephemeral layer): ```bash export PATH=$PATH:/home/node/.local/bin curl -sS https://bootstrap.pypa.io/get-pip.py -o /tmp/get-pip.py python3 /tmp/get-pip.py --user --break-system-packages pip3 install --user --break-system-packages graphiti-core falkordb sentence-transformers ``` ## File Layout All skill scripts live at: `memory-upgrade/` (workspace root) ``` memory-upgrade/ config.py # Service URLs + model names embedder.py # OllamaEmbedderClient + expert registry router.py # DomainRouter (hard + centroid + fanout) setup_graphiti.py # Graphiti factory (defaults to 'workspace' graph) write_path.py # ingest_memory(), ingest_workspace_memories() read_path.py # query_memory() — hybrid BM25+vector phase3_ingest.py # Seed ingestion (checkpoint-aware, re-runnable) phase4_query_test.py # Read path validation (7 test queries) phase6_full_ingest.py # Full workspace ingestion + centroid recalibration checkpoints/ # Phase state (JSON, safe to re-run) scripts/ # Skill scripts (install, ingest, query, status) ``` ## Common Tasks ### Query memory ```python # Write to a .py file, then run it import asyncio, sys sys.path.insert(0, '/path/to/memory-upgrade') from setup_graphiti import init_graphiti from read_path import query_memory from router import DomainRouter async def main(): g = await init_graphiti("workspace") router = DomainRouter(ollama_base_url="http://172.18.0.1:11436") edges, routing = await query_memory(g, router, "your question here", group_ids=["workspace"], limit=5) for e in edges: print(e.fact) await g.close() asyncio.run(main()) ``` Or use the convenience script: ```bash python3 memory-upgrade/scripts/query_memory.py "your question here" ``` ### Ingest new content ```bash python3 memory-upgrade/scripts/ingest.py --file path/to/file.md --domain project python3 memory-upgrade/scripts/ingest.py --text "Jebadiah decided X because Y" --domain personal ``` ### Check system status ```bash python3 memory-upgrade/scripts/status.py ``` ### Re-seed from workspace memory files ```bash python3 memory-upgrade/phase3_ingest.py # daily notes + MEMORY.md python3 memory-upgrade/phase6_full_ingest.py # broader workspace docs ``` ## Configuration Edit `memory-upgrade/config.py` to change endpoints or models: ```python OLLAMA_URL = "http://172.18.0.1:11436" # NVIDIA — embeddings AMD_OLLAMA_URL = "http://172.18.0.1:11437" # AMD — LLM (gemma4:e4b) LLM_MODEL = "gemma4:e4b" # entity extraction LLM EMBED_GENERAL = "nomic-embed-text" # 768-dim general embedder ``` ## Known Gotchas - **Data graph name = group_id**: Graphiti names the FalkorDB graph after the `group_id` passed to `add_episode()`. Always use `group_id="workspace"` and `init_graphiti("workspace")`. - **sim_min_score must be 0.0**: The default 0.6 blocks almost all results. Always set to 0.0. - **No `python3 -c` inline**: OpenClaw's obfuscation detector fires on it. Write to a temp file. - **Packages reinstall needed**: `/home/node/.local` is ephemeral. Re-run pip install after restart. - **Vector index**: Created in Phase 5. If the workspace graph is reset, re-run `phase5_vector_index.py`. ## Research Foundations See `references/research.md` for full citations.
