OpenAgentSkills

A community-driven library of reusable AI agent skills — drop one in and your agent gains a new superpower.

GitHub is where you contribute. SimplyUtils is where you discover.

Skills work across multiple agent environments: Claude Code, Cursor, Codex, Cline, Antigravity, and more.

Why OpenAgentSkills?

• Saves you time. Stop writing the same "review this component" or "write a commit message" prompts from scratch. Proven, battle-tested skills are ready to drop in.
• Agent-agnostic. You can use the same skill in Claude Code today and Cursor tomorrow. Skills are just robust instructions.
• Community-owned. Skills are contributed by real developers who use them in production. No vendor lock-in, no paywalls.
• Discoverable. Browse, search, and filter the entire library at simplyutils.com/ai-resources without digging through folders.

Quick Start

Get up and running in under 2 minutes:

# 1. Find a skill you need
npx openagentskills search "unit test"

# 2. Copy the skill into your project
mkdir -p .agents/skills/unit-test-writer
curl -o .agents/skills/unit-test-writer/SKILL.md \
  https://raw.githubusercontent.com/Notysoty/openagentskills/main/skills/unit-test-writer/SKILL.md

# 3. Tell your agent to use it
# "Write unit tests for src/auth.ts using the Unit Test Writer skill."

For Cursor: paste the ## The Prompt / Instructions section into your .cursorrules file.

How It Works

Step 1 — Find a skill
Browse the table above, run npx openagentskills search <query>, or visit simplyutils.com/ai-resources.

Step 2 — Drop it into your project
Copy the skill folder into your agent's skills directory:

your-project/
└── .agents/
    └── skills/
        └── git-commit-writer/
            └── SKILL.md

For Cursor, add the contents to your .cursorrules file or paste it as a custom prompt.

Step 3 — Use it
Tell your agent to use the skill by name. For example:

"Write a commit message for my staged changes using the Git Commit Writer skill."

# Your Skill Name

## What this skill does

## How to use

### Claude Code / Cline

Copy this file to `.agents/skills/your-skill-name/SKILL.md` in your project.

Skill Quality Standards

To be accepted, a skill must:

• Have a clear, specific use case (not too vague or too narrow)
• Include at least one real input → output example
• Be original (not a duplicate of an existing skill)
• Use the YAML frontmatter format correctly with all required fields

Why Tags?

• Tags: Define the capabilities, frameworks, or topics the skill relates to (e.g., react, seo, python, git). They let people easily find the right workflow for their current problem space.

Roadmap

• Web UI for searching and filtering skills at simplyutils.com/ai-resources
• Skill versioning so agents can pin to a specific version
• Automated CI validation of SKILL.md frontmatter on every PR
• Skill rating and usage stats from the community
• One-click install for supported agent environments
