Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Major AI Skills

Installable GitHub library of agentic skills / AI agent skills (SKILL.md playbooks) for Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, and more - focused on professional apps, token efficiency, and practical prompting habits.

Current release: V2.3.0. 402 canonical skills, including ten new AI evaluation, retrieval, privacy, and reliability workflows. Install the latest npm package or select a focused Claude/Codex plugin.

Coding agents can install exact skill IDs into the directory their host watches. You keep control: preview with --dry-run, filter by --skills / --category, or install a specialized pack.

Project / task
  -> you (or the agent) pick exact skill IDs from the catalog
  -> npx major-ai-skills --<host> --skills <ids> --dry-run
  -> review the plan
  -> install without --dry-run
  -> invoke with @skill-id

This is an independent community project. Product names (SolidWorks, Raycast, Claude, Cursor, Antigravity, etc.) are referenced only to describe compatibility and skill scope.

Why This Repo

  • Agentic skills that are installable, not just inspirational: npx major-ai-skills --claude|--cursor|--codex|--gemini|--antigravity places SKILL.md where your AI coding assistant already looks.
  • Product-depth skill library: CAD, video, 3D, GIS, medical, music, ERP, forensics, PLC, desktop utilities - not only generic coding tips.
  • Efficiency + common sense: token-saving techniques and plain-English prompting habits in the same catalog.
  • Built for major agent workflows: Claude Code skills, Cursor skills, Codex CLI skills, Gemini CLI skills, Antigravity skills, Kiro, OpenCode, and custom paths.
  • Focused delivery: specialized plugins and bundles so you do not overload Antigravity / Cursor context windows.
  • Inspect before installing: --dry-run, CATALOG.md, and skills_index.json.

Why not only browse folders?

A flat SKILL.md skill library with stable IDs, an index, and a host-aware installer turns prose into reproducible local agent capability - the distribution pattern popular search traffic expects from modern agent-skill repos, applied to our genuine skills.

Table of Contents

Installation

Prefer an exact reviewed set. Full Antigravity installs can exhaust context because the host watches ~/.agents/skills.

npx skills add alivirgo/Major-AI-Skills --list
npx skills add alivirgo/Major-AI-Skills --skill blender --skill figma -g -y

Individual listings are discovered through telemetry-enabled installs with the Vercel CLI. --list only previews discovery. Our separate major-ai-skills installer does not register installs with skills.sh. The generated skills.sh.json groups the repository page by category; it does not submit skills.

Quick FAQ

What are agentic skills / AI agent skills?

Agentic skills (also called AI agent skills, Claude Code skills, Cursor skills, or SKILL.md playbooks) are reusable instruction packages that teach coding agents how to run a workflow with clearer constraints. Major AI Skills is an installable skill library of those playbooks focused on professional apps and efficient prompting.

What is Major AI Skills?

A curated, installable GitHub library of 402+ agent skills for Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, and related AI coding assistants - covering CAD, video, 3D, design, desktop utilities, devops tools, token efficiency, and common-sense habits.

How do I install Claude Code skills or Cursor skills from this repo?

npx major-ai-skills --claude --skills <ids>
npx major-ai-skills --cursor --skills <ids>

See claude-code-skills.md and cursor-skills.md.

Should I install everything?

No. Prefer --skills or --category, or a specialized plugin. Antigravity watches ~/.agents/skills - a full dump can exhaust context. Use --all only when you intentionally accept that risk.

Where did the old folders go?

Application, efficiency, and common-sense skills now live under skills/<id>/SKILL.md. Optional model variants remain as gpt.md / gemini.md inside the same folder.

How do I browse?
