Second Brain
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.

Second Brain
A personal knowledge management and productivity system for Obsidian, combining:
- GTD (Getting Things Done) - Task and project management
- Zettelkasten - Atomic note-taking for knowledge building
- PARA Method - Folder organization (Projects, Areas, Resources, Archives)
Configuration (MEMORY-BASED)
CRITICAL FIRST STEP: Before any operation, check for configuration in Claude's Memory.
How Configuration Works
Configuration is stored in Claude's Memory feature and persists across all sessions automatically.
Why Memory? Skills in Claude Desktop run in a sandboxed environment with no file system access. Memory is the only way to persist configuration across sessions.
Once set up, Claude remembers:
- Your vault path
- Your name
- Whether setup is complete
- Your preferences
Configuration Check Flow
- Check Claude Memory for "Second Brain vault path"
- If found in Memory: Use the remembered vault path for all operations
- If NOT found in Memory: This is first-time setup - ask user for vault path
Checking Memory
At the start of ANY Second Brain operation, check if you remember the vault path:
