The Antigravity Skills ecosystem on GitHub exploded in 2026. There are now hundreds of public repositories offering pre-built SKILL.md playbooks for every domain imaginable — from security auditing and Kubernetes deployments to SEO optimization and SaaS metrics coaching. The problem is no longer finding skills; it is knowing which repositories are actually worth your time. This guide ranks and reviews the 10 best GitHub repositories for Antigravity Skills, with install commands, skill counts, star counts, and honest use-case assessments for each.

Why the GitHub Skills Ecosystem Matters in 2026

When Google Antigravity launched its agent-first IDE in late 2025, the SKILL.md format emerged as the universal language for packaging AI expertise. Within three months, GitHub became the de facto marketplace for skills — thousands of developers sharing, forking, and improving playbooks for every engineering and business domain.

The result: you no longer need to write every skill from scratch. The community has already built high-quality, battle-tested SKILL.md playbooks for the most common workflows. Your job as a developer in 2026 is less about authoring and more about curation — knowing which repositories to trust, which bundles fit your role, and how to layer community skills with your own custom ones.

The best skill repositories share three traits: they install cleanly with a single command, their skills have precise semantic trigger descriptions that actually fire reliably, and they are actively maintained with version numbers you can pin. The repos in this guide meet all three criteria.

New to Antigravity Skills entirely? Start with our complete guide on how to use Antigravity Skills before diving into this repository roundup. It covers SKILL.md authoring, semantic triggering, and the two-scope install system.

How to Evaluate an Antigravity Skills Repository

Before installing skills from any GitHub repo, check these five signals:

1. Stars and fork ratio: Stars signal popularity; forks signal that developers are actually using and customizing the skills — not just starring and forgetting. A healthy ratio is 1 fork per 5–8 stars.
2. Last commit date: The Antigravity skills format and best practices evolve quickly. Any repo not updated in 90+ days may have stale SKILL.md structures that trigger poorly on newer model versions.
3. Does it have a one-command installer?: Repos with an npx or npm CLI installer are far easier to update and maintain than manual clone-and-copy setups. Prefer repos with versioned installers.
4. Description quality in SKILL.md files: Open two or three skills at random. If the description fields are short, vague, or use passive language ("this skill does X"), semantic triggering will fail frequently. Good descriptions use active verbs and include example trigger phrases.
5. License: MIT or Apache-2.0 is essential for commercial projects. Some repos use CC-BY-NC which prohibits commercial use. Check before building a team workflow on top of a skill.

1. sickn33/antigravity-awesome-skills — The Master Library

GitHub: github.com/sickn33/antigravity-awesome-skills
Stars: 28,000+ | Forks: 4,700+ | License: MIT | Skills: 1,340+
Last updated: March 29, 2026 (v9.2.0)

This is the starting point for every developer building an Antigravity skill library. Antigravity Awesome Skills is an installable GitHub library of 1,340+ agentic skills for Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, Kiro, OpenCode, Copilot, and more — covering development, testing, security, infrastructure, product, and marketing domains.

What makes it stand out from every other repository on this list is not just the volume of skills — it is the infrastructure around them. The repo ships with a built-in npx CLI installer, role-based bundles (Web Wizard, Security Engineer, Essentials, TDD Architect, Loki Mode, Growth & Product), multi-skill Workflow files, and detailed documentation that answers the questions most beginners actually have: What do I do after installation? What should my prompts look like? How do I avoid context overload?

Who Should Install This

Every Antigravity user, without exception. Even if you only use 20 of the 1,340 skills, having the full catalog available means the agent can semantically discover the right skill for unexpected tasks you didn't plan for.

Install Commands

# Install all skills to Antigravity global path
npx antigravity-awesome-skills

# Install only the Essentials bundle (recommended first install)
npx antigravity-awesome-skills --bundle essentials

# Install for Claude Code
npx antigravity-awesome-skills --tool claude-code

# Install for Gemini CLI
npx antigravity-awesome-skills --tool gemini

# Install for Cursor
npx antigravity-awesome-skills --tool cursor

# Specify a custom path
npx antigravity-awesome-skills --path ./my-skills

Standout Skills in This Repo

brainstorming — turns rough ideas into structured MVP plans through structured questioning
security-auditor — OWASP-based security review for API endpoints and auth flows
analyze-project — forensic root cause analyzer that classifies scope deltas, rework patterns, and hotspots in Antigravity sessions
angular — modern Angular v20+ expert with Signals, Standalone Components, and SSR
active-directory-attacks — comprehensive AD penetration testing and red-team reconnaissance techniques

One Caveat

Installing all 1,340 skills to a single scope will cause context overload. When Antigravity loads metadata from every installed skill at session start, too many skills increase token usage and raise the chance of irrelevant auto-activation. Prefer targeted installs via search, tags, or bundles — install all is advanced and not recommended for most projects. Use bundles for your primary role and add individual skills as you discover needs.

2. VoltAgent/awesome-agent-skills — Official Vendor Skills

GitHub: github.com/VoltAgent/awesome-agent-skills
Stars: 13,300+ | License: MIT | Skills: 1,000+
Last updated: March 29, 2026

While sickn33 is the community aggregator, VoltAgent is the official vendor hub. This is where major technology companies publish and maintain their own Antigravity-compatible skill sets. The quality bar is higher because the skills are maintained by the same teams that built the products they describe.

Compatible with Claude Code, Codex, Antigravity, Gemini CLI, Cursor, GitHub Copilot, OpenCode, Windsurf, and more — the most contributed Agent Skills repository, built and maintained together with the community.

Official Vendor Skills Included

3. alirezarezvani/claude-skills — 192 Skills + 268 Python Scripts

GitHub: github.com/alirezarezvani/claude-skills
Stars: 5,200+ | License: MIT | Skills: 192 | Python tools: 268
Last updated: March 28, 2026

This is the most executable skill library on this list. Where other repos provide instruction files, alirezarezvani packs 268 Python CLI scripts alongside each skill — all using the standard library, zero pip installs required. This means skills can genuinely do things: calculate SaaS metrics, analyze brand voice, score tech debt, scaffold landing pages, and run RICE prioritization — not just give advice about them.

Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, and converts to 8 more tools via scripts/convert.sh. All 268 Python tools run anywhere Python runs.

Domain Coverage

Engineering: Security auditor, tech debt analyzer, API design, code review
Product: Senior PM agent with 6 knowledge domains, 12 templates, 30+ frameworks, SaaS metrics
Marketing: Content production, brand voice analysis, landing page scaffolder (TSX + Tailwind)
Finance: SaaS health check — MRR, churn, customer metrics calculator
C-Level Advisory: CTO advisor with tech debt scoring; product strategy frameworks
Compliance: GDPR, SOC2, regulatory checklist automation

Who Should Install This

Developers building full-stack SaaS products who want skills that actually compute things — not just advise. The Python tool bundle is uniquely valuable: you can run the scripts directly in the terminal, pipe their output into other commands, or use them as standalone utilities outside Antigravity.

Install Command

# Clone the repository
git clone https://github.com/alirezarezvani/claude-skills ~/claude-skills

# Convert for Antigravity
cd ~/claude-skills && ./scripts/convert.sh --tool antigravity

# Install
./scripts/install.sh --tool antigravity

# Or symlink the skills directory
ln -s ~/claude-skills/skills/* ~/.gemini/antigravity/skills/

Standout Scripts

# SaaS health check — calculate MRR, churn, and customer metrics
python3 finance/saas-metrics-coach/scripts/metrics_calculator.py \
  --mrr 80000 --customers 200 --churned 3 --json

# Tech debt scoring for a codebase
python3 c-level-advisor/cto-advisor/scripts/tech_debt_analyzer.py /path/to/codebase

# Brand voice analysis
python3 marketing-skill/content-production/scripts/brand_voice_analyzer.py article.txt

# RICE prioritization from CSV
python3 product-team/product-manager-toolkit/scripts/rice_prioritizer.py features.csv

4. guanyang/antigravity-skills — Auto-Syncing Multi-Source Aggregator

GitHub: github.com/guanyang/antigravity-skills
Stars: 3,000+ | License: MIT | Skills: 300+
Last updated: January 26, 2026

This repository solves a specific problem: staying current. Rather than manually watching upstream repos, guanyang/antigravity-skills ships with a skills_sources.json config and sync scripts that automatically pull the latest versions from all upstream skill sources. When you run git pull on this repo, every skill from every tracked upstream is updated at once.

The skills_sources.json file in the root directory is pre-configured with the upstream repositories for major skills and usually does not need manual adjustment. Run sync_skills.sh to sync all configured sources or just a specific one.

The repo also includes skills_index.json — a metadata index of all available skills with tags, descriptions, and cross-references — making it possible to discover skills programmatically rather than manually browsing directories.

Directory Structure

Who Should Install This

Teams who want a single maintained skills repo that stays current without manual intervention. Ideal for DevOps teams who need reproducible environments — pin the repo to a specific commit in CI, then control when to pull upstream updates.

Install Command

# Clone to a fixed location
git clone https://github.com/guanyang/antigravity-skills ~/antigravity-skills

# Global symlink for Antigravity
mkdir -p ~/.gemini/antigravity/skills
ln -s ~/antigravity-skills/skills/* ~/.gemini/antigravity/skills/

5. rmyndharis/antigravity-skills — Claude Code Agents Ported to Antigravity

GitHub: github.com/rmyndharis/antigravity-skills
Stars: 1,800+ | License: MIT (Original: © Claude Code Agents) | Skills: 300+
Last updated: January 19, 2026

This repository ports the entire Claude Code Agents ecosystem — domain skills, specialist agents, and orchestration workflows — into the Antigravity SKILL.md format. It is the most faithful adaptation of the Anthropic Claude Code skill architecture for Antigravity users.

This vault transforms the extensive Claude Code ecosystem into Antigravity Skills, providing your agent with repeatable workflows, domain expertise, and specialized tools across software development, operations, security, and business domains. Three types of Claude Code components are unified into the Antigravity format: Domain Skills, Specialist Agents, and Commands and Workflows.

Available Bundles

core-dev — foundational development skills including backend-architect, api-design-principles, code-review
security-core — security-auditor, security-scanning-security-hardening, pen-test scaffold
k8s-core — k8s-manifest-generator, cluster management, Helm chart skills
data-core — database optimization, schema migration, query performance
ops-core — deployment automation, infrastructure as code, monitoring setup

Semantic Trigger Examples from This Repo

These are actual semantic trigger matches from the catalog — useful for understanding how to phrase prompts:

"Help me design a REST API for a user service" → activates api-design-principles and backend-architect
"Scaffold a new FastAPI project" → activates python-development-python-scaffold
"Review this PR for security issues" → activates security-scanning-security-hardening or security-auditor
"Start a new feature track for login" → activates conductor-new-track

Install Command

# Search skills before installing
npx @rmyndharis/antigravity-skills search kubernetes

# Install a single skill
npx @rmyndharis/antigravity-skills install k8s-manifest-generator

# Install globally
npx @rmyndharis/antigravity-skills install bash-pro --global

# Install by tag
npx @rmyndharis/antigravity-skills install --tag kubernetes

# Install a bundle
npx @rmyndharis/antigravity-skills install --bundle k8s-core

# List what you have installed
npx @rmyndharis/antigravity-skills installed
npx @rmyndharis/antigravity-skills installed --global

6. BehiSecc/awesome-claude-skills — Security and Privacy Focus

GitHub: github.com/BehiSecc/awesome-claude-skills
Stars: 2,100+ | License: MIT | Focus: Security, privacy, and compliance
Last updated: March 31, 2026

This is the most comprehensive security-focused skills repository on GitHub. Where other repos treat security as one category among many, BehiSecc treats it as a first-class discipline — covering OWASP Top 10, ASVS 5.0, Trail of Bits auditing, secret management, PII sanitization, and prompt injection defense.

Security Skills Included

owasp-security — OWASP Top 10:2025, ASVS 5.0, and Agentic AI security (2026) with code review checklists, secure patterns, and language-specific quirks for 20+ programming languages
systematic-debugging — structured debugging protocol before proposing fixes for any bug, test failure, or unexpected behavior
Trail of Bits Security Skills — static analysis with CodeQL and Semgrep, variant analysis, code auditing, and fix verification (official Trail of Bits maintained)
varlock-claude-skill — secure environment variable management ensuring secrets never appear in Claude sessions, terminals, logs, or git commits
sanitize — detect and redact PII from text files across 15 categories (SSNs, credit cards, API keys, etc.), zero dependencies, all processing local
webapp-testing — toolkit for testing local web applications using Playwright
ironclaw-agent-guard — security review skill and CLI/MCP companion for risky tool calls, prompt injection, secret redaction, and audit-friendly agent workflows

Who Should Install This

Any team shipping software that handles user data, financial information, health records, or authentication. Also essential for any developer who is nervous about prompt injection in agent workflows — the ironclaw-agent-guard skill specifically addresses this attack vector.

Install Command

git clone https://github.com/BehiSecc/awesome-claude-skills ~/security-skills
ln -s ~/security-skills/skills/* ~/.gemini/antigravity/skills/

7. travisvn/awesome-claude-skills — Curated Claude Workflow List

GitHub: github.com/travisvn/awesome-claude-skills
Stars: 49,500+ | License: MIT | Type: Curated awesome-list (not an installer)
Last updated: February 19, 2026

With nearly 50,000 stars, travisvn/awesome-claude-skills is the most-starred repository on this list — but it is fundamentally different from the others. It is not an installable skill library; it is a curated awesome-list of the best Claude skills, tools, and resources across the entire ecosystem. Think of it as the index to find every other repo.

A curated list of awesome Claude Skills, resources, and tools for customizing Claude AI workflows — particularly Claude Code. The list is organized by category: official skills, community skills, MCP integrations, workflow tools, CLAUDE.md templates, and productivity utilities.

Why This List Is Worth Bookmarking

When you need a skill for a very specific use case — say, translating books, generating Excalidraw diagrams, or building a crypto data dashboard — travisvn's list is the fastest way to find if someone has already built it. The list is updated weekly and links directly to the install command for each entry.

Notable discoveries from this list include: CoinPaprika & DexPaprika Skills (real-time crypto data, no API key needed), RoundTable02/tutor-skills (transform any codebase into Obsidian quizzes), and deusyu/translate-book (parallel sub-agent book translation with resume support).

8. heraspec — Specs-as-Code for Antigravity

GitHub: github.com/topics/heraspec (multiple maintainers)
Stars: 4,200+ (main repo) | License: MIT | Focus: Specification-driven development
Last updated: March 28, 2026

Heraspec is a distinct approach to Antigravity development: instead of giving the agent open-ended instructions, you write structured spec files in Markdown and Heraspec skills interpret them. The philosophy is specs-as-code — your product requirements, API contracts, and architecture decisions become machine-readable specifications that the agent uses as a source of truth during implementation.

The core workflow: write a SPEC.md in your project, tell Antigravity to implement it, and the heraspec skill ensures the agent follows the specification contract exactly — checking implementation against spec at each step rather than drifting based on conversational context.

Who Should Install This

Engineering teams practicing specification-driven or contract-first development. Particularly valuable for: API-first teams defining OpenAPI specs before code, product teams bridging PRDs to implementation, and any project where "the agent did something reasonable but not what we specified" is a recurring complaint.

Install Command

# Install the heraspec skill for Antigravity
git clone https://github.com/heraspec/heraspec-antigravity-skill .agent/skills/heraspec

# Verify
cat .agent/skills/heraspec/SKILL.md | head -10

10. vudovn/antigravity-kit — Templates with Skills, Agents, and Workflows

GitHub: github.com/vudovn/antigravity-kit
Stars: 800+ | License: MIT | Skills: 33
Last updated: March 2026

antigravity-kit takes a different philosophy from the large aggregators: instead of 1,000+ skills, it ships 33 carefully composed templates that include Skills, Agent configurations, and Workflow files in a single installable kit. The focus is depth over breadth — each template covers a complete end-to-end pattern rather than a single skill.

This is the repo to use when you want to understand the relationship between Skills, Agents, and Workflows in practice. Each template shows how a skill feeds into an agent persona, which then executes a multi-step workflow. It is the best learning resource for developers building their own custom Antigravity agent architectures.

What's Included

33 pre-built skill definitions
Agent configuration templates for 5 roles (Reviewer, Builder, Researcher, Optimizer, Communicator)
10 Workflow files showing multi-skill execution chains
Full documentation on composing Skills + Agents + Workflows together

Install Command

git clone https://github.com/vudovn/antigravity-kit ~/antigravity-kit

# Install skills
ln -s ~/antigravity-kit/skills/* ~/.gemini/antigravity/skills/

# Copy agent configs
cp ~/antigravity-kit/agents/* ~/.gemini/antigravity/agents/

Honorable Mentions Worth Bookmarking

These repos did not make the main list for one reason or another — niche focus, smaller scale, or an early-access state — but are genuinely useful for specific use cases:

ComposioHQ/awesome-claude-skills (28,900+ stars): Another large curated list, similar to travisvn but maintained by the Composio team. Heavy on MCP integration skills — particularly useful if you are building workflows that connect agents to external SaaS tools via Composio's 1,000+ app integrations.
orchestra-research/ai-research-skills: Comprehensive open-source library of AI research and engineering skills maintained by Orchestra Research. Covers machine learning, HuggingFace, vLLM, and LLM training workflows. Package the skills and your agent will be an AI research agent with full horsepower.
ReScienceLab/opc-skills: Skills for solopreneurs — SEO, geo-targeting, and LLM-optimized content production. Small but very well-written trigger descriptions that fire reliably.
affaan-m/everything-claude-code: Complete Claude Code configuration collection from the Anthropic hackathon winner. Only 8 skills but each one is exceptional quality and carefully maintained.
sstklen/claude-api-cost-optimization: Skills focused on reducing Claude API token costs by 50–90% through smart context compression, model routing, and caching strategies. Useful for teams with significant API bills.
NeoLabHQ/write-concisely: Applies the principles from The Elements of Style to make documentation clearer and more professional by eliminating wordiness and improving structure. Surprisingly useful for technical writing tasks.

Best Install Strategy: Don't Install Everything

After reviewing 1,340+ skills across 10 repositories, the single most common mistake is installing everything. When Antigravity loads metadata from every installed skill at session start, more skills means more token usage and a higher chance of irrelevant auto-activation. A context-overloaded agent performs worse than one with 20 well-chosen skills.

Here is the three-layer install strategy used by experienced Antigravity developers:

Layer 1 — Global Foundation (15–25 skills)

Install the Essentials bundle from sickn33 globally. These are the skills you use every day across every project: git-commit-formatter, brainstorming, code-review, documentation-writer, and security-auditor.

npx antigravity-awesome-skills --bundle essentials

Layer 2 — Role Bundle (20–40 skills)

Add the bundle that matches your primary role:

# Frontend / full-stack
npx antigravity-awesome-skills --bundle web-wizard

# Security / DevSecOps
npx antigravity-awesome-skills --bundle security-engineer

# Backend / infrastructure
npx @rmyndharis/antigravity-skills install --bundle k8s-core

# SaaS product / marketing
npx skills add coreyhaines31/ai-seo

Layer 3 — Project-Specific Skills (5–10 skills)

For each project, add workspace-scope skills for project-specific workflows — your deployment script, your database health check, your team's code review standards. These live in .agent/skills/ and get committed to Git.

mkdir -p .agent/skills/deploy-staging
# Write your SKILL.md for this project's specific deploy workflow

This three-layer approach keeps your global context lean while giving you deep coverage for your daily role and project-specific precision where it matters. To learn how to write custom project-specific skills, see our complete Antigravity Skills guide.

Frequently Asked Questions

What is the single best GitHub repository for Antigravity Skills?: sickn33/antigravity-awesome-skills — 28k+ stars, 1,340+ skills, npx installer, role bundles, workflow files, and cross-agent compatibility. It is the starting point for every developer. Install with npx antigravity-awesome-skills --bundle essentials to avoid context overload.
How do I install skills from GitHub into Antigravity?: For the main library: npx antigravity-awesome-skills. For rmyndharis: npx @rmyndharis/antigravity-skills install [skill-name]. For repos without a CLI, clone and symlink: ln -s ~/cloned-repo/skills/* ~/.gemini/antigravity/skills/. See the skills install guide for full path details.
Can the same GitHub skills be used for Claude Code and Antigravity?: Yes. The SKILL.md format is a cross-agent open standard. The same file works with Claude Code, Cursor, Codex CLI, and Gemini CLI. Use the --tool claude-code or --tool cursor flags with the npx installer, or manually copy skills to each tool's path. For Claude Code specifically, see our Claude Code setup guide.
What is the difference between antigravity-awesome-skills and VoltAgent/awesome-agent-skills?: antigravity-awesome-skills is the largest community aggregator — breadth across all categories. VoltAgent is the official vendor hub — fewer skills but officially maintained by the companies that built the products (OpenAI, Figma, Supabase, Composio). Use both: sickn33 for coverage, VoltAgent for mission-critical integrations.
Are there Antigravity skills specifically for security or DevOps?: Yes. For security: BehiSecc/awesome-claude-skills has OWASP Top 10:2025, ASVS 5.0, Trail of Bits auditing, and prompt injection defense. For DevOps and Kubernetes: rmyndharis/antigravity-skills has the k8s-core bundle with manifest generation, Helm charts, and cluster management skills.
Do I need to restart Antigravity after installing new skills?: Yes. Antigravity reads skill metadata at session start. After installing new skills to either scope, close and reopen the Antigravity session (or run openclaw gateway restart if using OpenClaw) so the agent picks up the new skills. For more on managing skills post-install, see our OpenClaw CLI commands reference.

Conclusion

The GitHub skills ecosystem for Antigravity in 2026 is rich, fast-moving, and genuinely useful — but only if you approach it with a strategy rather than installing everything at once. Here is the recommended path based on this review:

Start with sickn33/antigravity-awesome-skills — install the Essentials bundle globally
Add your role bundle — Web Wizard, Security Engineer, TDD Architect, or Growth & Product
Browse travisvn/awesome-claude-skills — use it as a discovery index for niche skills
Install BehiSecc/awesome-claude-skills — if your project handles user data or requires OWASP compliance
Check VoltAgent/awesome-agent-skills — add official Figma, Supabase, or Composio skills if you use those platforms
Write 3–5 project-specific SKILL.md files — for your team's deployment workflow, code review standards, and recurring automation

The developers who build the best Antigravity skill libraries in 2026 are the ones who treat curation as a craft — not a one-time install. Every skill you add, test, and refine compounds over time.
