New Here? Start Here!

If you searched for Claude Code skills, Cursor skills, Codex CLI skills, Gemini CLI skills, or AI agent skills on GitHub, this is the fastest path to installing a serious working library and using it the same day.

1. 🐣 Context: What is this?

Antigravity Awesome Skills (Release 8.7.1) is a large, installable skill library for AI coding assistants. It includes onboarding docs, bundles, workflows, generated catalogs, and a CLI installer so you can move from discovery to actual usage without manually stitching together dozens of repos.

AI agents are smart, but they still need task-specific operating instructions. Skills are focused markdown playbooks that teach an agent how to perform a workflow repeatedly and with better context, whether that means deployment, API design, testing, product strategy, SEO, or documentation.

2. ⚡️ Quick Start (1 minute)

Install once; then use Starter Packs in docs/users/bundles.md to focus on your role.

1. Install:

   # Default: ~/.gemini/antigravity/skills (Antigravity global). Use --path for other locations.
   npx antigravity-awesome-skills
   

2. Verify:

   test -d ~/.gemini/antigravity/skills && echo "Skills installed in ~/.gemini/antigravity/skills"
   

3. Run your first skill:

   "Use @brainstorming to plan a SaaS MVP."

4. Pick a bundle:

   • Web Dev? start with Web Wizard.
   • Security? start with Security Engineer.
   • General use? start with Essentials.

3. 🧠 How to use

Once installed, just ask your agent naturally:

"Use the @brainstorming skill to help me plan a SaaS." "Run @lint-and-validate on this file."

Compatibility & Invocation

These skills follow the universal SKILL.md format and work with any AI coding assistant that supports agentic skills.

[!TIP] Default installer path: ~/.gemini/antigravity/skills (Antigravity global). Use --path ~/.agent/skills for workspace-specific install. For manual clone, .agent/skills/ works as workspace path for Antigravity. OpenCode Path Update: opencode path is changed to .agents/skills for global skills. See Place Files directive on OpenCode Docs.

[!TIP] Windows Users: use the standard install commands. The legacy core.symlinks=true / Developer Mode workaround is no longer required for this repository.

Installation

To use these skills with Claude Code, Gemini CLI, Codex CLI, Kiro CLI, Kiro IDE, Cursor, Antigravity, OpenCode, or AdaL:

Option A: npx (recommended)

npx antigravity-awesome-skills

2. Verify the default install:

test -d ~/.gemini/antigravity/skills && echo "Skills installed"

3. Use your first skill:

Use @brainstorming to plan a SaaS MVP.

4. Browse starter collections in docs/users/bundles.md and execution playbooks in docs/users/workflows.md.

Option B: Claude Code plugin marketplace

If you use Claude Code and prefer the plugin marketplace flow, this repository now ships a root .claude-plugin/marketplace.json:

/plugin marketplace add sickn33/antigravity-awesome-skills
/plugin install antigravity-awesome-skills

This installs the same repository-backed skill library through Claude Code's plugin marketplace entrypoint.

Choose Your Tool

Best Skills By Tool

If you want a faster answer than "browse all 1,311+ skills", start with a tool-specific guide:

• Claude Code skills: install paths, starter skills, prompt examples, and plugin marketplace flow.
• Cursor skills: best starter skills for .cursor/skills/, UI-heavy work, and pair-programming flows.
• Codex CLI skills: planning, implementation, debugging, and review skills for local coding loops.
• Gemini CLI skills: starter stack for research, agent systems, integrations, and engineering workflows.
• AI agent skills guide: how to evaluate skill libraries, choose breadth vs curation, and pick the right starting point.

Security Posture

These skills are continuously reviewed and hardened, but the collection is not "safe by default". They are instructions and examples that can include risky operations by design.

• Runtime hardening now protects the /api/refresh-skills mutation flow (method/host checks and optional token gate) before any repo mutation.
• Markdown rendering in the web app avoids raw HTML passthrough (rehype-raw) and follows safer defaults for skill content display.
• A repo-wide SKILL.md security scan checks for high-risk command patterns (for example curl|bash, wget|sh, irm|iex, command-line token examples) with explicit allowlisting for deliberate exceptions.
• Pull requests that touch SKILL.md files now also run an automated skill-review GitHub Actions check, so contributors and maintainers get a second pass focused on skill structure and review quality.
• Maintainer-facing tooling has additional path/symlink checks and parser robustness guards for safer sync, index, and install operations.
• Security test coverage for endpoint authorization, rendering safety, and doc-risk patterns is part of the normal CI/release validation flow.

Curated Collections

Bundles are curated groups of skills for a specific role or goal (for example: Web Wizard, Security Engineer, OSS Maintainer).

They help you avoid picking through the full catalog one by one.

⚠️ Important: Bundles Are NOT Separate Installations!

Common confusion: "Do I need to install each bundle separately?"

Answer: NO! Here's what bundles actually are:

What bundles ARE:

• ✅ Recommended skill lists organized by role
• ✅ Curated starting points to help you decide what to use
• ✅ Time-saving shortcuts for discovering relevant skills

What bundles are NOT:

• ❌ Separate installations or downloads
• ❌ Different git commands
• ❌ Something most users need to activate during normal install

How to use bundles:

1. Install the repository once (you already have all skills)
2. Browse bundles in docs/users/bundles.md to find your role
3. Pick 3-5 skills from that bundle to start using in your prompts
4. Reference them in your conversations with your AI (e.g., "Use @brainstorming...")

If Antigravity starts hitting context limits with too many active skills, the optional activation scripts in docs/users/agent-overload-recovery.md can materialize only the bundles or skill ids you want in the live Antigravity directory.

For detailed examples of how to actually use skills, see the Usage Guide.

Examples:

• Building a SaaS MVP: Essentials + Full-Stack Developer + QA & Testing.
• Hardening production: Security Developer + DevOps & Cloud + Observability & Monitoring.
• Shipping OSS changes: Essentials + OSS Maintainer.

Documentation

Troubleshooting

Windows install note

Use the normal install flow on Windows:

git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills

If you have an older clone created around the removed symlink workaround, reinstall into a fresh directory or rerun the npx antigravity-awesome-skills installer.

Windows truncation or context crash loop

If Antigravity or a Jetski/Cortex-based host keeps reopening into a truncation error, use the dedicated recovery guide:

• docs/users/windows-truncation-recovery.md

That guide includes:

• backup paths before cleanup
• the storage folders that usually need to be cleared
• an optional batch helper adapted from issue #274

Linux and macOS agent overload

If Antigravity becomes unstable only when too many skills are active at once, use the cross-platform overload guide:

• docs/users/agent-overload-recovery.md

Fixing agent overload (activation scripts)

If your agent is struggling with context window limits due to too many loaded skills, use the activation scripts. They keep the full library in a separate archive folder and only activate the bundles or skills you need into the live Antigravity skills directory.

Important Usage Instructions:

1. First, manually close the repository (e.g., exit your AI agent or close your IDE).
2. Open a terminal inside the folder where you cloned this repository (NOTE: repository has to be cloned).
3. Run the script located in the scripts folder.

macOS/Linux examples:

# Activate specific bundles
./scripts/activate-skills.sh "Web Wizard" "Integration & APIs"

# Activate literal skill ids
./scripts/activate-skills.sh brainstorming systematic-debugging

# Clear and reset (archives the live directory first)
./scripts/activate-skills.sh --clear

Windows examples:

:: Activate specific bundles
.\scripts\activate-skills.bat "Web Wizard" "Integration & APIs"

:: Clear and reset (removes all skills except the Essentials bundle)
.\scripts\activate-skills.bat --clear

Web App

The web app is the fastest way to navigate a large repository like this.

Run locally:

npm run app:install
npm run app:dev

That will copy the generated skill index into apps/web-app/public/skills.json, mirror the current skills/ tree into apps/web-app/public/skills/, and start the Vite development server.

Hosted online: The same app is available at https://sickn33.github.io/antigravity-awesome-skills/ and is deployed automatically on every push to main. To enable it once: Settings → Pages → Build and deployment → Source: GitHub Actions.
