From the README
Your vault is the memory. Claude, Grok Bot, Codex - same brain.
Your vault outlives whichever CLI you switch to.
Crew works without Obsidian. Claude Code, Codex, Cursor, and Grok Bot share job records in any plain folder. Each agent sees what the others finished and can leave a lesson for review.
Restart Claude Code, then type
/crew setup. Pick~/creworwiki/team/inside your Obsidian vault. Codex users run/hooksonce to trust Crew's hooks. Setup prints a Grok Bot profile block to paste.Setup, exact commands, and limits. Python 3.10 or later; no extra packages for Crew. Shared agent memory isn't new. What Crew adds is the three parts above.
An evolution of Karpathy's LLM Wiki pattern: a vault that rewrites itself.
Every source updates existing pages instead of just appending new ones. Contradictions reconcile automatically. Your vault compounds while you sleep.
Powered by OKM - Open Knowledge Metabolism: every stored fact is timeless, dated, or a pointer - so your knowledge base never fills with facts that used to be true.
