What are Skills?

A lightweight, open format for extending AI agent capabilities with specialized knowledge and workflows.

Core Concept
At its core, a skill is a folder containing a SKILL.md file with metadata and instructions.
my-skill/
├── SKILL.md          # Required: instructions + metadata
├── scripts/          # Optional: executable code
├── references/       # Optional: documentation
└── assets/           # Optional: templates, resources

Discovery

Load only name and description at startup

Activation

Read full instructions when task matches

Execution

Follow instructions, load resources as needed

Why Agent Skills?

Agents are increasingly capable, but often lack the context they need to do real work reliably.

For Skill Authors

Build capabilities once and deploy them across multiple agent products.

For Compatible Agents

Support for skills lets end users give agents new capabilities out of the box.

For Teams and Enterprises

Capture organizational knowledge in portable, version-controlled packages.

What Can Skills Enable?

Extend agent capabilities with specialized knowledge and workflows

Domain Expertise

Package specialized knowledge into reusable instructions, from legal review processes to data analysis pipelines.

New Capabilities

Give agents new capabilities like creating presentations, building MCP servers, and analyzing datasets.

Repeatable Workflows

Turn multi-step tasks into consistent and auditable workflows.

Interoperability

Reuse the same skill across different skills-compatible agent products.

Supported By Leading Tools

Open Skills are supported by leading AI development tools

OpenCodeCursorAmpLettaGooseGitHubVS CodeClaude CodeClaude

The Skills format was originally developed by Anthropic, released as an open standard, and has been adopted by a growing number of agent products.

Simple & Powerful

The Skills format is designed to be easy to author and implement

Simple Format

A skill is just a folder with a SKILL.md file containing YAML frontmatter and Markdown instructions.

Progressive Disclosure

Load only metadata at startup, activate full instructions when needed.

Extensible

Include scripts, references, and assets to support complex workflows.

Portable

Skills are just files—easy to edit, version, and share.

SKILL.md Example
Every skill starts with a SKILL.md file containing YAML frontmatter
