About obsidian-wiki
obsidian wiki is a Python package and agent skill framework for maintaining a personal knowledge base in Obsidian. It lives in the Obsidian, markdown, and AI agent ecosystem, where agents can read and run skills from a shared .skills/ directory. The project presents itself as a digital brain that remembers what a user figures out, connects new material to existing notes, and answers questions from that knowledge.
