Claude Skills GitHub Repository: Browse & Contribute
A practical guide to the main GitHub repositories people reference when learning about Claude Skills, including Anthropic's public repo and a few community resources that should be verified before use. Find skills, learn from examples, and contribute your own.
Primary Public Repository to Check First
The main public reference point is Anthropic's anthropics/skills repository.
anthropics/skills
What's inside:
The repo is organized into two main areas:
1
skills/ — Skill implementations
2
spec/ — Agent Skills Specification
The open standard specification file (agent-skills-spec.md) is also hosted in this repo, alongside the reference implementation at agentskills.io.
How to install skills from this repo
Using the currently supported Claude Code plugin flow or manual installation:
Bash
You can usually install skills either through the supported plugin or install source flow in your environment, or by cloning a repository and placing the skill folder in your personal or project skills directory such as ~/.claude/skills/ or .claude/skills/. Always verify the current installation method in the official documentation or repository README before use. /plugin install example-skills@anthropic-agent-skills
Manual installation: Clone the repo and copy the skill folder to your skills directory:
- Personal: ~/.claude/skills/
- Project: .claude/skills/
Reference: check the current anthropics/skills README for installation details and licensing notes.
What's in the Official Repo — Full Skills Catalog
A detailed breakdown of every skill category in the anthropics/skills repository.
Document Skills (Source-Available)
These skills power Claude's built-in file creation capabilities on Claude.ai. They are source-available for reference but not open source.
Example Skills (Apache 2.0)
Open-source skills that demonstrate patterns and possibilities. These are the skills most useful for learning how to build your own.

Community Skills Repositories & Tools
Beyond Anthropic's official repo, the community has built a growing ecosystem of skills, curated lists, and tooling.
obra/superpowers — Highlight
The superpowers library by Jesse Vincent is one of the most comprehensive community skills collections. It provides:
- A broad collection of community-maintained skills for daily development work
- Built-in commands: /brainstorm, /write-plan, /execute-plan
- Skills-search tool for finding relevant skills
- Community-editable companion repo (superpowers-skills)
- Plugin install source installation for Claude Code
OpenSkills — Community Installer
OpenSkills is a community tool built around the SKILL.md format. Installation commands and compatibility may change, so verify current usage in the repository before adopting it in production.
Bash
npx openskills install anthropics/skills # Install official skills npx openskills install anthropics/skills --universal # Universal format npx openskills sync # Refresh installed skills npx openskills read skill-creator # Read a specific skill
How to Contribute Skills to GitHub
Whether you're contributing to Anthropic's official repo or publishing your own, here's how.
Contributing to anthropics/skills
The official repo accepts contributions. Follow these steps:
Publishing your own skills repository
You can publish skills in any public GitHub repo. Other developers can install them via:
Bash
# Claude Code plugin install /plugin install your-skill-name@your-github-username # Or via OpenSkills npx openskills install your-username/your-repo
Best practices for publishable skills
Security reminder
Skills can execute arbitrary code in Claude's environment. Anthropic recommends using skills only from trusted sources — those you created yourself or obtained from Anthropic. Always review community skills before installing, just like any open-source code.

Frequently Asked Questions
Where is the official Claude Skills GitHub repository?
The official public repository is github.com/anthropics/skills, maintained by Anthropic. It includes Claude-compatible skills, examples, and related resources, and is a useful public reference point for understanding how skills are structured.
Are Claude Skills on GitHub open source?
It depends on the skill. Example skills in the repository (algorithmic-art, brand-guidelines, internal-comms, etc.) are licensed under Apache 2.0 — fully open source. Document skills (docx, pdf, pptx, xlsx) are source-available for reference but not open source.
How do I install a skill from GitHub?
In Claude Code, use the plugin flow command: You can usually install skills either through the supported plugin or install source flow in your environment, or by cloning a repository and placing the skill folder in your personal or project skills directory such as ~/.claude/skills/ or .claude/skills/. Always verify the current installation method in the official documentation or repository README before use.. Alternatively, clone the repository and copy the skill folder to ~/.claude/skills/ (personal) or .claude/skills/ (project). Skills may be discovered automatically depending on the environment and installation method.
Are there community-built skills outside the official repo?
Yes. The community ecosystem includes obra/superpowers, travisvn/awesome-claude-skills, numman-ali/openskills, and SkillsMP.com. These are community tools and aggregators rather than Anthropic official resources, so verify current scope and installation details before relying on them.
How does Verdent work with Claude Skills from GitHub?
Verdent supports Claude Skills through its Claude Code integration. Install skills from any GitHub repo via Claude Code plugins, and Verdent's multi-agent architecture lets you run multiple skill-powered tasks in parallel. Each agent operates in an isolated workspace with its own installed skills, making it ideal for testing and comparing different skills simultaneously.
