- Remove verbatim Nate Herk transcript from .raw/ (copyright) - Rewrite wiki/sources page as synthesis + attribution + link to original - Keeps all original concept/entity pages (our synthesis, not third-party content) - .raw/ folder preserved for users to add their own sources - This repo is now safe to share publicly as a plugin/skill library

- "Hot cache (~500 words) enables cross-project context without crawling the full wiki"
|

- "One article generates 15-25 wiki pages with full cross-references"
|
|
- "One user dropped token usage by 95% switching from inline context files to a wiki"
|
|
- "Obsidian is the IDE, Claude is the programmer, the wiki is the codebase"
|
|
- "Index file is sufficient at small scale (~100 sources) — no RAG infrastructure needed"

# Nate Herk — Obsidian + Karpathy Just 10x'd Claude Code Projects
|
|
|
|
**Original:** [Watch on YouTube →](https://youtube.com/@nateherk)
|
|
**Credit:** All ideas in this summary belong to Nate Herk and Andrej Karpathy.
|
|
|
|
> This page is a wiki-style synthesis of the source — an example of what cosmic-brain produces after ingesting a video/transcript. The raw source is not included in the repo.

## What This Source Is
|
|
|
|
Nate Herk demonstrates the [[LLM Wiki Pattern]] in practice using Claude Code and Obsidian. He shows two live vaults: a YouTube transcript archive (36 videos) and a personal second brain. He breaks down [[Andrej Karpathy]]'s original post and walks through a 5-minute setup.

## Key Insights
|
|
|
|
**The wiki compounds.** Normal AI chat is ephemeral — knowledge disappears when the session ends. The wiki pattern changes this: every source ingested, every answer filed back, every connection made persists permanently. See [[Compounding Knowledge]].
|
|
|
|
**The hot cache is the force multiplier.** A ~500-word file (`wiki/hot.md`) captures what happened recently. New sessions read it first. Cross-project references read it first. It saves crawling dozens of wiki pages just to answer "where were we?" See [[Hot Cache]].
|
|
|
|
**The stack is intentionally simple.** Claude Code + Obsidian + a folder of markdown files. No vector databases, no embeddings, no infrastructure. The index file alone navigates hundreds of pages.
|
|
|
|
**Cross-project power.** Other Claude Code projects can reference this vault via their CLAUDE.md. Nate's executive assistant reads from his personal brain vault. Token usage dropped significantly vs inline context files.
|
|
|
|
**95% token reduction.** One X user turned 383 scattered files and 100+ meeting transcripts into a compact wiki and dropped token usage by 95% when querying with Claude.
|
|
|
|
**At scale.** The index file alone is sufficient for hundreds of pages. Vector RAG only becomes necessary at millions of documents.

## The Live Demo
|
|
|
|
Nate ingested one article (AI 2027) and Claude produced 23 wiki pages in ~10 minutes:
|
|
- 1 source summary
|
|
- 6 entity pages (people)
|
|
- 5 organization pages
|
|
- 1 AI systems page
|
|
- Multiple concept pages
|
|
- 1 analysis
|
|
- Open questions
|
|
|
|
This is what one ingest looks like when the wiki pattern is applied correctly.

## Obsidian as IDE
|
|
|
|
Obsidian serves as the visual layer. Key features used:
|
|
- **Graph view** — see which pages are hubs and which are orphans
|
|
- **Backlinks** — follow relationships between pages
|
|
- **Dataview** — query pages by frontmatter
|
|
- **Web Clipper** — send articles to `.raw/` from any browser in one click
|
