Combines GTD, Zettelkasten, and PARA into a unified Obsidian system with six workflows: quick capture for dumping thoughts into daily inbox notes, inbox processing that routes items to projects or permanent notes, daily planning that generates prioritized tasks based on your energy and context, evening closeout for reflection and tomorrow's draft, and Excalidraw diagram creation. The setup is clever: configuration persists in Claude's memory across sessions, which solves the sandboxing problem elegantly. It'll proactively offer to capture insights during conversations, which feels a bit pushy at first but becomes useful when you're researching something and want to preserve what you learned. Best for people who actually commit to a knowledge system rather than collecting productivity porn.
