#381 of 783 by Stars among GitHub repos
Cross-CLI skill for Obsidian: turn your vault into a living AI-first second brain across Claude Code, Codex, Gemini, OpenCode, Hermes, and Pi. 44 commands - self-rewriting notes, local+hybrid semantic search, key-less web research, /obsidian-architect codebase docs, and scheduled agents that maintain the vault while you sleep.
About

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.

write-time AI-first validator · /create-command interview flow · multilingual trigger schema
