1-Sentence Summary

Installable library of 1,450+ agentic skills to supercharge any AI coding assistant.

🔥 Key Capabilities & USP

• Installable CLI Library: Run npx antigravity-awesome-skills to instantly install 1,450+ SKILL.md playbooks directly into your AI assistant's expected directory. This solves the critical pain point of manually copying or configuring skills, turning a tedious setup into a single command.
• Tool-Agnostic Support: Supports 10+ major AI coding tools (Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, Kiro, OpenCode, GitHub Copilot) with dedicated installation flags (--claude, --cursor, --gemini, etc.). This eliminates the fragmentation of having different skill formats for different tools, providing a unified skill ecosystem.
• Role-Based Bundles & Workflows: Pre-packaged bundles and ordered execution playbooks for development, testing, security, infrastructure, product, and marketing roles. This reduces onboarding time from "discovery" to "first skill usage" by providing ready-to-use, curated collections.
• Plugin-Safe Distribution: Supports both full-library installs and marketplace-style plugin distributions for Claude Code and Codex CLI. This gives teams flexibility to adopt either a comprehensive library or a lightweight, curated plugin model.
• Hosted Web UI & Catalog: Includes a generated CATALOG.md and a GitHub Pages web UI for browsing the skill library. This solves the discoverability problem, allowing users to search and explore skills without needing to clone the repository.

Technical Architecture

Component	Technology / Approach
CLI Tool	npm-installable package, executed via npx
Installation Mechanism	Shallow clone of the GitHub repository to a target directory
Default Target Path	~/.gemini/antigravity/skills
Tool Detection	CLI flags (--claude, --cursor, --gemini, --codex, --antigravity, --kiro, --path)
Skill Format	SKILL.md playbooks
Registry System	Version 11.0.0 with registry sync for updates
Catalog Generation	Auto-generated CATALOG.md and hosted GitHub Pages web UI
Filtering	Category and risk-level flags (--category, --risk)

Quick Start Guide

# Full library install (default: ~/.gemini/antigravity/skills)
npx antigravity-awesome-skills

# Verify the install
test -d ~/.gemini/antigravity/skills && echo "Skills installed in ~/.gemini/antigravity/skills"

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

# Advanced: filtered install
npx antigravity-awesome-skills --path .agents/skills --category development,backend --risk safe,none

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

Pros, Cons & Use Cases

Pros

• Massive, curated library of 1,450+ skills covering a wide range of development and operational tasks.
• Extremely easy installation via a single npx command with tool-specific flags.
• Active and growing community with 37k+ GitHub stars and regular version updates (V11.0.0).
• Flexible deployment supporting both full-library and plugin-based installations.

Cons

• GitHub Copilot requires manual paste of skills/rules (no automated installer).
• Full library install uses shallow clone by default, which may lack full git history for debugging or rollback.
• Requires CLI familiarity and basic knowledge of AI coding assistant configuration.

Who should NOT use this?

• Developers who only use GitHub Copilot and want an automated installation experience (requires manual setup).
• Teams with strict security policies that prohibit executing npx commands from external repositories without review.
• Users who prefer minimal, hand-curated skill sets and find 1,450+ skills overwhelming or unnecessary.

Ideal Use Cases

• Onboarding new team members to AI-assisted development with a standardized, pre-configured skill library.
• Multi-tool development environments where engineers switch between Claude Code, Cursor, and Codex CLI.
• DevOps and security teams needing structured playbooks for infrastructure, testing, and security tasks.
• Rapid prototyping where developers want to immediately leverage AI agents for common coding tasks without manual setup.

Community & Activity

This project is on a meteoric trajectory with 37,009 GitHub stars and active maintenance (last updated May 2026). The V11.0.0 release with registry sync and the hosted web UI demonstrate a mature, rapidly evolving project. The combination of a large skill library, multi-tool support, and an active community makes this a must-watch project for anyone serious about AI-assisted development. The momentum suggests this is quickly becoming the de facto standard for agentic skill management.
