Lightweight open format for extending AI agent capabilities.

Overview

Agent Skills is an open standard for packaging procedural knowledge and context into portable folders that agents load on demand. It defines a simple SKILL.md format with metadata and instructions, enabling domain expertise and repeatable workflows across compatible AI agents.

# Agent Skills\n\n[](https://discord.gg/MKPE9g8aUy)\n\nA standardized way to give AI agents new capabilities and expertise.\n\n## What are Agent Skills?\n\nAgent Skills are a lightweight, open format for extending AI agent capabilities with specialized knowledge and workflows.\n\nAt its core, a skill is a folder containing a `SKILL.md` file. This file includes metadata (`name` and `description`, at minimum) and instructions that tell an agent how to perform a specific task. Skills can also bundle scripts, reference materials, templates, and other resources.\n\n```\nmy-skill/\n├── SKILL.md          # Required: metadata + instructions\n├── scripts/          # Optional: executable code\n├── references/       # Optional: documentation\n├── assets/           # Optional: templates, resources\n└── ...               # Any additional files or directories\n```\n\n## Why Agent Skills?\n\nAgents are increasingly capable, but often don't have the context they need to do real work reliably. Skills solve this by packaging procedural knowledge and company-, team-, and user-specific context into portable, version-controlled folders that agents load on demand. This gives agents:\n\n- **Domain expertise**: Capture specialized knowledge — from legal review processes to data analysis pipelines to presentation formatting — as reusable instructions and resources.\n- **Repeatable workflows**: Turn multi-step tasks into consistent, auditable procedures.\n- **Cross-product reuse**: Build a skill once and use it across any skills-compatible agent.\n\n## How do Agent Skills work?\n\nAgents load skills through **progressive disclosure**, in three stages:\n\n1. **Discovery**: At startup, agents load only the name and description of each available skill, just enough to know when it might be relevant.\n\n2. **Activation**: When a task matches a skill's description, the agent reads the full `SKILL.md` instructions into context.\n\n3. **Execution**: The agent follows the instructions, optionally exe
