Install

Skills CLI

npx skills add briiirussell/cybersecurity-skills

Asks which skills and agents to install. Just one: npx skills add briiirussell/cybersecurity-skills --skill ai-risk-management — add -g for every project.

Claude Code

git clone https://github.com/briiirussell/cybersecurity-skillscp -r "cybersecurity-skills/skills/ai-risk-management" ~/.claude/skills/

Copies the ai-risk-management skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add briiirussell/cybersecurity-skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
