Install
Skills CLI

Asks which skills and agents to install. Just one: npx skills add alice-dot-io/caterpillar --skill code-reviewer — add -g for every project.
Claude Code
git clone https://github.com/alice-dot-io/caterpillarcp -r "caterpillar/example_skills/code-reviewer" ~/.claude/skills/

Plugin
/plugin marketplace add alice-dot-io/caterpillar
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.

In the author's own words, from each skill's SKILL.md.

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.
