Install
Skills CLI
npx skills add levnikolaevich/claude-code-skills
Asks which skills and agents to install. Just one: npx skills add levnikolaevich/claude-code-skills --skill ln-21-system-design-baseline-builder — add -g for every project.
Claude Code
git clone https://github.com/levnikolaevich/claude-code-skillscp -r "claude-code-skills/plugins/architecture-suite/skills/ln-21-system-design-baseline-builder" ~/.claude/skills/
Copies the ln-21-system-design-baseline-builder skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add levnikolaevich/claude-code-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.
