Install

Skills CLI

npx skills add fcsouza/agent-skills

Asks which skills and agents to install. Just one: npx skills add fcsouza/agent-skills --skill engineering-betterauth-integration — add -g for every project.

Claude Code

git clone https://github.com/fcsouza/agent-skillscp -r "agent-skills/skills/betterauth-integration" ~/.claude/skills/

Copies the engineering-betterauth-integration skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add fcsouza/agent-skills

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