Wiki Brain Skill — Documentation skill for Claude Code

Wiki-Brain

A Claude Code Skill by [@tenfoldmarc](https://www.instagram.com/tenfoldmarc)

Turn Claude Code into a knowledge base that *compounds.* Every conversation you have from now on feeds a personal wiki you browse in Obsidian. Claude gets smarter about YOUR stuff over time — and answers questions faster by querying a knowledge graph instead of re-reading files every time.

Built on Andrej Karpathy's [LLM Wiki pattern](https://gist.github.com/karpathy) and powered by [Graphify](https://github.com/tenfoldmarc/graphify-skill).

What It Does

1. Walks you through installing Obsidian + a vault (or uses your existing one)
2. Installs Graphify — the tool that builds a knowledge graph from your notes so Claude can query it
3. Creates your wiki structure — raw/ for sources, wiki/ for Claude-maintained pages, log.md for a timeline
4. Patches your CLAUDE.md with instructions so Claude knows to use the wiki in every session
5. Installs a SessionEnd hook — automatically rebuilds your knowledge graph on a cadence you pick (3 days, 7 days, or manual only)
6. Gives you commands to ingest sources, query the wiki, health-check it, and recall recent activity

Every conversation becomes compound interest. Drop articles, transcripts, papers, screenshots into `raw/` — Claude reads them, extracts key info, writes wiki pages, cross-links everything, and keeps it all maintained. You browse the results in Obsidian with graph view.

Requirements

• A Mac, Linux, or Windows computer
• Claude Code installed and working
• Python 3 (comes pre-installed on most systems)
• Obsidian (free — the skill walks you through installing it if you don't have it)

Don't worry about connecting these manually — the skill walks you through everything on first run.
