What problem does it solve? AI chat characters forget past conversations across sessions and channels. This Skill bridges a local Qdrant vector database to WebChat, QQ Bot, and Telegram Bot so each character retains isolated long-term memories that can be searched and injected into the LLM prompt every turn. ## Core Features & Use Cases - Vector Memory Search: Queries Qdrant with embeddings from a local server (port 9999, all-MiniLM-L6-v2) and returns relevance-scored memories for prompt injection. - Memory Write & List: Extracts key facts from conversation messages, embeds them, and stores them per character via user_id isolation. - Behavior Engine Integration: Adjusts search queries and result limits based on relationship stage, affection, and conflict state, then tier-injects memories by score (>=0.7 required, >=0.5 natural, >=0.3 optional). - Use Case: When a user asks their AI girlfriend "do you remember what I like?", the Skill searches Qdrant for that character's stored preferences and injects the relevant memories into the system prompt before the LLM responds. ## Quick Start Ask the AI to search mem0 memories for character natsume with the query "今天心情怎么样" and inject the results into the conversation context.
