**TL;DR** — Write notes that capture a single idea each, link them densely to related notes. Your vault becomes a self-organizing knowledge graph instead of a folder of essays.

## What makes a Zettel

A Zettelkasten note (German for "slip box"):

- **Captures one idea.** Not a topic — an idea. Not "Productivity" — "Why mornings are best for hard work."
- **Is written in your own words.** Quoting sources is fine; but the synthesis is yours.
- **Links to related Zettels.** Liberally. Every concept that connects.
- **Has a stable, unique title.** Future-you can find it.
- **Stands alone.** Re-read it 3 years from now and it should still make sense.

## Why bother

The point isn't taking notes. The point is the **connections between notes**, which only become visible when notes are atomic. A 2000-word essay-style note hides 5–10 ideas inside it. Each of those ideas could link to different things. Atomic notes surface those links.

After a year of consistent Zettel writing, the graph view becomes useful for thinking — not just pretty art.

## How it pairs with Claude Code

Several skills become more powerful with atomic notes:

- **[Research Synthesizer](/workflows/07-research-synthesizer/)** — works better when source notes are already atomic
- **[Spaced Repetition](/workflows/09-spaced-repetition/)** — atomic notes make 1–2 perfect flashcards; essays make 20 mediocre ones
- **Orphan detection** — atomic + densely linked means orphans really *are* orphans. The MOC Maintainer can flag them honestly.

Claude can also help atomize: paste an essay, ask "split this into atomic Zettels" — get back 5–10 candidate notes with suggested links.

## Where to put them

Either:

- **Dedicated folder:** `40-Resources/zettels/` — clean separation
- **Mixed in `40-Resources/`** with a `#zettel` tag — looser

Start with dedicated. Move to mixed once you have ~100 notes and start craving cross-pollination with the rest of your vault.
