The brain is self-contained — ships with the full book text and all 72 mental models bundled. The 72-skill pack is a derived .zip artifact built from the same source.

Downloads

Install the brain (recommended)

unzip elons-brain.skill
cp -R elon ~/.claude/skills/

One skill installed. It ships with the book text at ~/.claude/skills/elon/corpus/book-of-elon.txt, all 72 mental models at ~/.claude/skills/elon/skills/<name>/MODEL.md, and recipes at ~/.claude/skills/elon/recipes/. The elon skill reads from those paths on demand via Read and Grep tools.

Install the pack (alternative)

unzip elons-brain-pack.zip -d ~/.claude/skills/

72 individual skills extracted directly into ~/.claude/skills/, each as a fully-formed Claude Code skill.

What /elon actually does

1. Identify 1-3 relevant mental models from the inline catalog
2. Read ./skills/<name>/MODEL.md for the actual how-to + quotes
3. Grep ./corpus/book-of-elon.txt for book passages with page numbers
4. Apply lenses to user's specifics, synthesize, cite

The book

Distilled from The Book of Elon by Eric Jorgenson (Scribe Media, 2026). Full plaintext (411KB, 8178 lines, page-marked) ships with the brain under the author's free-distribution release. Buying the physical or digital copy is still encouraged — the included text is for the AI to read, not a replacement for human reading.
