CSSI Claude Skills

A curated collection of Claude Code skills developed by Northwestern University's Center for Science of Science & Innovation (CSSI).

Getting Started

Install as a Claude Code Plugin

Connect your Claude Code instance to this skills marketplace by running:

claude skill add-marketplace https://github.com/Northwestern-CSSI/cssi-claude-skills

This registers the repository as a skill source, making all available skills accessible from your Claude Code environment.

Enable Auto-Update

claude skill enable-auto-update cssi-skills

With auto-update enabled, Claude Code will periodically sync with this repository and pull any new or updated skills automatically.

Browse Available Skills

After installation, view all available skills with:

claude skill list

Or invoke any skill directly by name during a Claude Code session using the /<skill-name> syntax.
