Install
Skills CLI
npx skills add oribarilan/97
Asks which skills and agents to install. Just one: npx skills add oribarilan/97 --skill api-design — add -g for every project.
Claude Code
git clone https://github.com/oribarilan/97cp -r "97/skills/api-design" ~/.claude/skills/

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.
