Install
Skills CLI
npx skills add nextlevelbuilder/skillx
Asks which skills and agents to install. Just one: npx skills add nextlevelbuilder/skillx --skill hol-guard — add -g for every project.
Claude Code
git clone https://github.com/nextlevelbuilder/skillxcp -r "skillx/.claude/skills/hol-guard" ~/.claude/skills/
Copies the hol-guard skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add nextlevelbuilder/skillx
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.

marketing-mindset
Use when the user needs a professional marketer's operating mindset for any marketing, growth, or client-acquisition task — finding first customers, writing an ad or landing page, designing ad creatives and visuals (how the eye works: background, scene, hero, movement), evaluating an idea, deciding whether to do X to get Y, positioning or launching a B2B or SaaS product, running cold outreach, se…

skillx
Find, compare, vet and use AI agent skills from the SkillX.sh catalog. Use when the user asks to discover, search, compare, evaluate, install or run an agent skill (a SKILL.md package) for a task, or asks whether a skill exists for something. Do not use for ordinary coding, writing or research tasks that do not involve finding or managing agent skills.

full-tree-94
Regression fixture with 94 nested files (modules, assets, references, scripts) for whole-tree releases.
apps/web/ on GitHub (opens in a new tab)tests/ fixtures/ full-tree-94/ SKILL.md
No skill matches that filter.
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.
