What problem does it solve? AI assistants forget everything between sessions, forcing you to reintroduce yourself repeatedly. This Skill gives the AI a persistent, structured memory of you—your experiences, personality, values, decisions, and recent life events—stored in a local Markdown knowledge base that you fully own. ## Core Features & Use Cases - Tiered Retrieval Strategy: A four-level (L0–L3) decision tree determines when and how deeply to read the knowledge base before each reply, balancing context depth against cost. - Three Update Triggers: Manual commands ("记一下"), automatic summaries every 10 conversation turns, and proactive AI observations of your behavioral patterns written to an observations file. - Dedup & Contradiction Handling: Merges repeated facts, upgrades confidence levels, and preserves contradictory statements as evolution history rather than deleting old judgments. - Cognitive Companionship: When you feel stuck, it replays your past decisions and stated values to offer grounded options instead of generic advice. - Use Case: After weeks of chatting, you ask "Should I take this job offer?" The AI reads your values file and past major decisions, then shows how this choice aligns or conflicts with what you said mattered most. ## Quick Start Say "记一下:我今天决定接受新公司的 offer" and the AI will archive the decision into the knowledge base with confidence tagging and follow-up questions.
