zettelkasten

zettelkasten is a skill for Claude Code, Codex from malue-ai/dazee-small. It costs 25 tokens per session (783 once invoked), scanned A, original, MIT.

A note-taking system that stores small Markdown files, each focused on one idea, with links to related notes. It is based on the Zettelkasten method, a way to build a connected personal knowledge base over time.

In plain words
What is it for?
Use it to create atomic notes, tag and search them, link related concepts, and generate an overview of connections in a knowledge network.
Why use it?
It removes the problem of keeping notes as isolated pages that are hard to revisit or connect. Links, tags, and searches help surface relationships between ideas.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

zettelkasten scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

卡片笔记法(Zettelkasten)

用卢曼卡片笔记法管理知识:原子化笔记、双向链接、渐进式涌现洞察。

使用场景

  • 用户说「帮我做读书笔记」「用卡片笔记法整理这个概念」
  • 用户说「这个概念和之前那个有什么关联」
  • 用户说「看看我的笔记之间有什么联系」
  • 用户在学习新知识时想建立系统化的知识网络

执行方式

卡片结构

每张卡片存储为 Markdown 文件,放在 ~/Documents/xiaodazi/zettelkasten/ 目录:

---
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。
参见 [[202602201530]] Anki 间隔算法。

核心操作

创建卡片

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
→ 回复:卡片已创建 ✅「间隔重复的遗忘曲线」
  可能相关:「主动回忆」「Anki 间隔算法」,要链接吗?

发现关联

用户:看看我关于学习方法的笔记有什么联系
→ 检索标签为「学习方法」的所有卡片
→ 分析内容相关性
→ 生成知识图谱概览:

  主动回忆 ←→ 间隔重复
       ↓           ↓
  费曼技巧 ←→ 遗忘曲线

搜索与浏览

# 全文搜索
grep -rl "间隔重复" ~/Documents/xiaodazi/zettelkasten/

# 按标签
grep -l "tags:.*学习方法" ~/Documents/xiaodazi/zettelkasten/*.md

卡片原则

  1. 原子性:每张卡片只包含一个概念
  2. 用自己的话写:不要直接复制粘贴
  3. 建立链接:每张新卡片至少链接一张已有卡片
  4. 持续增长:不追求完美,先写再完善

输出规范

  • 创建时自动建议关联卡片
  • 每张卡片简短(100-300 字)
  • 链接使用 [[ID]] 格式
  • 定期生成知识图谱概览,帮助用户发现意外关联

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
