name: memory-lancedb-pro description: This skill should be used when working with memory-lancedb-pro, a production-grade long-term memory MCP plugin for OpenClaw AI agents. Use when installing, configuring, or using any feature of memory-lancedb-pro including Smart Extraction, hybrid retrieval, memory lifecycle management, multi-scope isolation, self-improvement governance, or any MCP memory tools (memory_recall, memory_store, memory_forget, memory_update, memory_stats, memory_list, self_improvement_log, self_improvement_extract_skill, self_improvement_review).

memory-lancedb-pro

Production-grade long-term memory system (v1.1.0-beta.8) for OpenClaw AI agents. Provides persistent, intelligent memory storage using LanceDB with hybrid vector + BM25 retrieval, LLM-powered Smart Extraction, Weibull decay lifecycle, and multi-scope isolation.

For full technical details (thresholds, formulas, database schema, source file map), see `references/full-reference.md`.

Applying the Optimal Config (Step-by-Step Workflow)

When the user says "help me enable the best config", "apply optimal configuration", or similar, follow this exact procedure:

Step 1 — Present configuration plans and let user choose

Present these three plans in a clear comparison, then ask the user to pick one:

---

**Plan A — 🏆 Full Power (Best Quality)**

• Embedding: Jina jina-embeddings-v5-text-small (task-aware, 1024-dim)
• Reranker: Jina jina-reranker-v3 (cross-encoder, same key)
• LLM: OpenAI gpt-4o-mini (Smart Extraction)
• Keys needed: JINA_API_KEY + OPENAI_API_KEY
• Get keys: Jina → https://jina.ai/api-key · OpenAI → https://platform.openai.com/api-keys
• Cost: Both paid (Jina has free tier with limited quota)
• Best for: Production deployments, highest retrieval quality

**Plan B — 💰 Budget (Free Reranker)**

• Embedding: Jina jina-embeddings-v5-text-small
• Reranker: SiliconFlow BAAI/bge-reranker-v2-m3 (free tier available)
• LLM: OpenAI gpt-4o-mini
• Keys needed: JINA_API_KEY + SILICONFLOW_API_KEY + OPENAI_API_KEY
• Get keys: Jina → https://jina.ai/api-key · SiliconFlow → https://cloud.siliconflow.cn/account/ak · OpenAI → https://platform.openai.com/api-keys
• Cost: Jina embedding paid, SiliconFlow reranker free tier, OpenAI paid
• Best for: Cost-sensitive deployments that still want reranking

**Plan C — 🟢 Simple (OpenAI Only)**

• Embedding: OpenAI text-embedding-3-small
• Reranker: None (vector+BM25 fusion only, no cross-encoder)
• LLM: OpenAI gpt-4o-mini
• Keys needed: OPENAI_API_KEY only
• Get key: https://platform.openai.com/api-keys
• Cost: OpenAI paid only
• Best for: Users who already have OpenAI and want minimal setup

**Plan D — 🖥️ Fully Local (Ollama, No API Keys)**

• Embedding: Ollama mxbai-embed-large (1024-dim, recommended) or nomic-embed-text:v1.5 (768-dim, lighter)
• Reranker: None — Ollama has no cross-encoder reranker; retrieval uses vector+BM25 fusion only
• LLM: Ollama via OpenAI-compatible endp
