# Maintain a Claude Code and Obsidian second brain with second-brain-os

Use second-brain-os to give Claude Code a repeatable Obsidian knowledge-base workflow with skills, commands, agents, scripts, and a starter vault.

## Prerequisites

Claude Code, Obsidian, Git, a local markdown vault, and the second-brain-os repo assets for skills, commands, agents, scripts, and starter vault content.

## Installation

Install or set up from the source-backed instructions:

Clone https://github.com/undefined-ui/second-brain-os, create a local brain workspace, copy the repo's skills, commands, agents, scripts, and starter vault into the workspace's Claude Code and vault folders, then run Claude Code from that workspace and follow the documented quickstart.
