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.

Featured Workflows

Pick a concrete task, inspect its instructions, and install only that skill. Each walkthrough includes prerequisites, a ready-to-use prompt, expected outputs, and acceptance checks.

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.

Installation

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

Browse the repository on skills.sh. Choose exact skill IDs from CATALOG.md:

Browse the web catalog, with a direct link for every skill, such as FFmpeg.

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. See the maintainer indexing guide for verification and publishing steps.

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?

• CATALOG.md
• skills_index.json
• Hosted site
