868 Agentic Skills, One Command: Antigravity Awesome Skills Becomes the Cross-Tool Skill Standard

As the AI coding assistant landscape fragments across Claude Code, Gemini CLI, Codex CLI, Cursor, and GitHub Copilot, one open-source repository is emerging as a shared skill layer for all of them. Antigravity Awesome Skills (v5.4.0, “Workflows Edition”) bundles 868+ curated agentic skills into a single MIT-licensed repository, consolidating official skills from Anthropic, Vercel Labs, OpenAI, Supabase, Microsoft, and Google DeepMind alongside a large community contribution base.

The Problem It Solves

AI coding agents are powerful general-purpose systems, but they lack context-specific knowledge: your company’s deployment protocol, the exact syntax for AWS CloudFormation, or how your team writes commit messages. Skills—small markdown files that teach agents how to do specific tasks—fill this gap.

The challenge is that skills created for Claude Code don’t automatically work in Cursor, and Gemini CLI has its own conventions. Antigravity Awesome Skills addresses this with a universal SKILL.md format that works across eight tools:

# Install once—covers all tools
npx antigravity-awesome-skills

# Use naturally in any supported tool
"Use @brainstorming to plan a SaaS MVP."
"Run @sql-injection-testing on this endpoint."

Cross-Tool Compatibility

The v5.4.0 release supports eight AI coding assistants:

Tool	Type	Invocation
Claude Code	CLI	>> /skill-name
Gemini CLI	CLI	Use skill-name...
Codex CLI	CLI	Use skill-name...
Antigravity IDE	IDE	Agent Mode: Use skill...
Cursor	IDE	@skill-name in Chat
GitHub Copilot	Extension	Paste content manually
OpenCode	CLI	opencode run @skill-name
AdaL CLI	CLI	Auto (on-demand load)

The recommended universal installation path is ~/.agent/skills/, with tool-specific paths available through installer flags:

npx antigravity-awesome-skills --claude   # → .claude/skills/
npx antigravity-awesome-skills --gemini   # → .gemini/skills/
npx antigravity-awesome-skills --cursor   # → .cursor/skills/
npx antigravity-awesome-skills --codex    # → .codex/skills/

Official Skills from Major Vendors

What distinguishes this from a typical community curations is the inclusion of official skills from the companies building the tools themselves:

• anthropics/skills — Document manipulation (DOCX, PDF, PPTX, XLSX), Brand Guidelines, Internal Communications
• vercel-labs/agent-skills — React Best Practices, Web Design Guidelines
• openai/skills — Agent skills, Skill Creator, Concise Planning
• supabase/agent-skills — Postgres Best Practices
• microsoft/skills — Azure cloud services, Bot Framework, Cognitive Services, enterprise patterns across .NET, Python, TypeScript, Go, Rust, and Java
• google-gemini/gemini-skills — Gemini API and SDK interactions
• remotion-dev/skills — Video creation in React, 28 modular rules

Having these official vendor skills consolidated in a single installable package means a developer can access Anthropic’s official document manipulation skills and Microsoft’s Azure patterns through the same npx command as community security testing skills.

868 Skills Across Nine Domains

Category	Focus	Example Skills

Development	Language mastery, framework patterns	typescript-expert, python-patterns, react-patterns
General	Planning, docs, product ops, writing	brainstorming, doc-coauthoring, writing-plans
Infrastructure	DevOps, cloud, serverless, CI/CD	docker-expert, aws-serverless, vercel-deployment
Security	AppSec, pentesting, vulnerability analysis	api-security-best-practices, sql-injection-testing, vulnerability-scanner
Testing	TDD, test design, QA workflows	test-driven-development, testing-patterns, test-fixing
Workflow	Automation, orchestration, agents	workflow-automation, inngest, trigger-dev

v5.4.0: Bundles vs. Workflows

The “Workflows Edition” designation in v5.4.0 reflects a distinction between two organizational layers:

Bundles are curated skill lists organized by developer role—Web Wizard, Security Engineer, OSS Maintainer, and so on. They help narrow down which skills to use from a catalog of 868+.

Workflows are step-by-step execution sequences for concrete goals. Current workflows include:

• Ship a SaaS MVP
• Security Audit for a Web App
• Build an AI Agent System
• QA and Browser Automation (with optional @go-playwright for Go stacks)

The distinction matters for agents: bundles answer “which skills should I have?” while workflows answer “in what order should I execute them?”

The SKILL.md Standard

All skills follow a universal SKILL.md format with required frontmatter (name and description). The repository ships a validation script (python3 scripts/validate_skills.py) that contributors must run before submitting PRs.

This standardization is what enables cross-tool portability. The same markdown file that Claude Code reads from .claude/skills/ can be placed in .gemini/skills/ for Gemini CLI or .cursor/skills/ for Cursor without modification. The format abstraction decouples skill content from tool-specific invocation conventions.

Community Scale

With 40+ named contributors and skills sourced from over 20 community repositories, this is well past the single-maintainer stage:

• rmyndharis/antigravity-skills: 300+ enterprise skills and the catalog generation logic that structures the entire repository
• zebbern/claude-code-guide: ~60 security-focused skills
• VoltAgent/awesome-agent-skills: 61 high-quality skills including official team contributions from Sentry, Trail of Bits, Expo, and Hugging Face
• affaan-m/everything-claude-code: Skills from an Anthropic hackathon winner

Relevance to Today’s Gemini CLI Announcement

This repository’s name is directly connected to Google DeepMind’s Antigravity IDE, announced yesterday alongside Gemini CLI. The repository explicitly supports Antigravity IDE as one of its eight target platforms, placing Google’s new agent development environment on equal footing with Claude Code.

This matters structurally: if a developer builds a skill library in Antigravity Awesome Skills, that library works whether they’re using Claude Code, Gemini CLI, or Antigravity IDE. In a market where Anthropic’s OAuth ban is pushing some users toward OpenAI’s Codex (as reported yesterday), having a portable skill layer that isn’t tool-locked has direct practical value.
