​
Required for all skills

Every Brain OS skill requires:
  • Claude Code — the AI coding environment that runs the skills
  • An Obsidian vault — or any markdown-based vault that follows the expected structure
Most skills — all daily operations and thinking tools — work with just Claude Code and Obsidian. The Python setup below is only needed if you use /self-learn, /audit, or /chain for book learning.

​
Required for self-learn, audit, and chain only

The knowledge pipeline skills (/self-learn, /audit, /chain) require:
  • Python 3.12+
  • notebooklm-py CLI installed at ~/.local/bin/notebooklm
  • Python packages: ebooklib, beautifulsoup4
1

Install notebooklm-py

Follow the setup instructions at github.com/nicholasgasior/notebooklm-py. Confirm the CLI is available at ~/.local/bin/notebooklm after install.
2

Navigate to the scripts directory

cd ~/.brain-os/skills/self-learn/scripts
3

Create a virtual environment

python3 -m venv .venv
4

Activate the virtual environment

source .venv/bin/activate
5

Install the required packages

pip install ebooklib beautifulsoup4

The ebooklib package handles epub parsing for book extraction. beautifulsoup4 processes the HTML content inside epub files. Both are only used by the /self-learn pipeline scripts.
