Introduction

AI coding assistants have exploded in 2025-2026. Claude Code, Cursor, Gemini CLI, GitHub Copilot, Codex CLI — the list keeps growing. But here's the dirty secret: out of the box, these tools are generalists. They know a lot about everything, but they don't know your company's deployment protocol, your preferred testing framework, or your team's architecture patterns.

That's where agentic skills come in. And one project has assembled the largest open-source collection of them: Antigravity Awesome Skills.[1]

With 946+ battle-tested skills that work across 10+ AI coding tools, this is the single biggest upgrade you can make to your AI-assisted development workflow — and it installs in under 60 seconds.

1. What Are Agentic Skills?

Agentic skills are small markdown files that teach AI agents how to perform specific tasks. Think of them as instruction manuals — not code that runs automatically, but knowledge the AI reads and applies contextually.

When you use Claude Code and type /brainstorming help me plan a SaaS, the agent reads the brainstorming skill file to understand exactly how to structure creative ideation. When you ask Cursor @react-best-practices review my component, it loads the React skill and applies battle-tested patterns.

The key insight: skills are declarative, not imperative. They contain expert knowledge — best practices, step-by-step workflows, command examples, error handling patterns — that the AI agent applies using its own reasoning. This makes them incredibly flexible compared to rigid plugins or extensions.

Why this matters for developers:

• Consistency — Your AI follows the same patterns every time, not hallucinating different approaches per session
• Team alignment — Share skills across your team so everyone's AI codes the same way
• Expertise on demand — Don't know CloudFormation? The skill does. Don't know penetration testing? There's a skill for that.
• Tool-agnostic — Write once, use across Claude Code, Cursor, Gemini CLI, and more

The standard format across tools is a SKILL.md file (or AGENTS.md, CLAUDE.md, .cursorrules depending on the tool). Antigravity standardizes on SKILL.md and maps it to each tool's expected path.[2]

2. The Antigravity Collection

Antigravity Awesome Skills (currently at Release 6.3.1) is a curated, open-source library of 946 high-performance agentic skills designed to work across all major AI coding assistants.[1] It's maintained by sickn33 and includes official skills from Anthropic, OpenAI, Google, Microsoft, Vercel, and Supabase.

The project's tagline says it all: "Transform your AI assistant into a full-stack digital agency."

Supported Tools (10+)

This cross-tool compatibility is a massive advantage. You write skills once and they work everywhere. If you switch from Claude Code to Gemini CLI, your skills come with you.

Skill Categories (9 Domains)

The 946 skills are organized into specialized domains covering the entire software development lifecycle:

3. Installation & Setup

Installation is remarkably simple. One command, works for any tool:

Option A: npx (Recommended)

# Default: installs to ~/.gemini/antigravity/skills
npx antigravity-awesome-skills

# Tool-specific installs:
npx antigravity-awesome-skills --claude     # → .claude/skills/
npx antigravity-awesome-skills --cursor     # → .cursor/skills/
npx antigravity-awesome-skills --gemini     # → .gemini/skills/
npx antigravity-awesome-skills --codex      # → .codex/skills/
npx antigravity-awesome-skills --kiro       # → .kiro/skills/

# Custom path:
npx antigravity-awesome-skills --path ./my-skills

That's it. One command. No API keys, no configuration, no build step. The installer handles everything, and if you've already installed, running it again does a git pull to update.[3]

Option B: Git Clone

# For Claude Code:
git clone https://github.com/sickn33/antigravity-awesome-skills.git .claude/skills

# For Cursor:
git clone https://github.com/sickn33/antigravity-awesome-skills.git .cursor/skills

Option C: Kiro IDE GUI Import

Kiro IDE users can import individual skills through the GUI: open the Agent Steering & Skills panel, click + → Import a skill → GitHub, and paste the skill URL.[4]

4. Notable Skills & Bundles

With 946 skills, finding what you need could be overwhelming. That's where bundles come in — curated collections organized by role.[5]

Curated Bundles

Important: Bundles are NOT separate installations. When you install the repo, you get all 946 skills. Bundles are just curated recommendations to help you know which skills to start using first.[5]

Standout Individual Skills

5. How to Actually Use Them

Once installed, using skills is dead simple. You just reference them naturally in conversation with your AI agent:[6]

# Claude Code
>> /brainstorming help me plan a SaaS for restaurant inventory management

# Cursor
@react-best-practices review this component for performance issues

# Gemini CLI
Use the systematic-debugging skill to help me find the memory leak in this server

# Codex CLI
Use lint-and-validate on the src/ directory

The AI reads the referenced skill file, loads the expert knowledge, and applies it to your request. No special syntax — just tell the AI what skill to use and what you need.

Workflows: Skills in Sequence

Beyond individual skills, Antigravity also supports workflows — ordered sequences of skills for complex goals:[7]

• Ship a SaaS MVP — brainstorming → architecture → senior-fullstack → testing-patterns → git-pushing
• Security Audit — ethical-hacking-methodology → vulnerability-scanner → api-security → security-auditor
• Build an AI Agent System — rag-engineer → prompt-engineer → langgraph → testing-patterns

Workflows are documented in docs/WORKFLOWS.md and also available as machine-readable JSON for automation.

6. Why This Is a Game-Changer

If you're using Claude Code or Cursor without agentic skills, you're leaving massive productivity on the table. Here's why the Antigravity collection specifically matters:

1. Instant expertise across 9 domains. You don't need to be a security expert to run a thorough security audit. You don't need to know CloudFormation to write production-ready templates. The skills carry the expert knowledge; the AI applies it.

2. Consistency at scale. Without skills, every AI session starts fresh. The AI might structure a React component differently each time. With skills, you get consistent, battle-tested patterns — every time, every team member.

3. Cross-tool portability. Switch from Claude Code to Gemini CLI? Your skills come with you. This is huge in a market where new AI coding tools launch monthly.

4. Official backing. These aren't random community scripts. The collection includes official skills from Anthropic (Claude's creator), OpenAI, Google DeepMind, Vercel, and Supabase. That's production-grade quality.[1]

5. Zero lock-in. It's MIT-licensed, open-source, and installable in one command. No vendor lock-in, no subscriptions, no API keys needed for the skills themselves.

7. Alternatives & Competitors

Antigravity's main advantages over alternatives: sheer scale (946 vs 380), curated bundles for different roles, workflow support for multi-step processes, and the widest tool compatibility (10+ tools vs 5-6). It also includes a local interactive web app for browsing and searching skills.

8. Community & Contributing

Antigravity Awesome Skills is fully open-source under the MIT license.[10] The project welcomes contributions:

• Submit new skills — Follow the SKILL.md format and submit a PR
• Improve existing skills — Better instructions, more examples, bug fixes
• Create bundles — Curate skill collections for new roles or use cases
• Build workflows — Design multi-skill execution sequences
• Report issues — Found a skill that doesn't work? Open an issue

The project also accepts support via Buy Me a Coffee and GitHub stars. Given the scope of the collection (946 skills across 9 domains), community contribution is essential for keeping skills current as tools and frameworks evolve.
