Manage knowledge with Luhmann's Zettelkasten method: atomic notes, bidirectional links, and progressively emergent insights.
Use Cases
- The user says "Help me take reading notes" or "Organize this concept using the Zettelkasten method"
- The user says "What is the connection between this concept and the previous one"
- The user says "See what connections there are between my notes"
- The user wants to build a systematic knowledge network when learning new knowledge
Execution Method
Card Structure
Each card is stored as a Markdown file in the ~/Documents/xiaodazi/zettelkasten/ directory:
---
id: "202602261430"
title: "间隔重复的遗忘曲线"
tags: [学习方法, 记忆]
links: ["202602251000", "202602201530"]
created: "2026-02-26T14:30:00"

间隔重复基于艾宾浩斯遗忘曲线：新学的知识在 24 小时内遗忘 70%，
但每次复习都会延长记忆保持时间。
最佳复习间隔：1天 → 3天 → 7天 → 14天 → 30天
与 [[202602251000]] 主动回忆 结合效果最好。

Core Operations
Create Cards：
用户：帮我记一个笔记——间隔重复利用遗忘曲线原理，通过在最佳时间点复习来巩固记忆
→ 生成唯一 ID（时间戳格式）
→ 提取关键概念作为标签
→ 搜索已有卡片，建议可能的关联
→ 创建 Markdown 文件

Card Principles
- Atomicity: Each card contains only one concept
- Write in your own words: Do not copy and paste directly
- Establish links: Each new card links to at least one existing card
- Continuous growth: Do not pursue perfection; write first, then refine
Output Specifications
- Automatically suggest related cards when creating
- Each card is short (100-300 characters)
- Links use the
[[ID]]format - Regularly generate a knowledge graph overview to help users discover unexpected connections
