## What Are Agent Skills
|
|
|
|
Agent Skills are modular, standardized `SKILL.md` packages that give agents on-demand capabilities via progressive disclosure: lightweight metadata can load early, full instructions load only when relevant, and supporting resources are accessed when needed.
|
|
|
|
`agent-skills` · `ai-agents` · `skill-md` · `progressive-disclosure` · `context-management`.

## Frequently Asked Questions
|
|
|
|
### What are Agent Skills
|
|
|
|
Agent Skills are modular `SKILL.md` packages that provide on-demand capabilities without loading all knowledge up front.
|
|
|
|
### How do Agent Skills differ from fine-tuning
|
|
|
|
Fine-tuning changes model weights, while skills provide runtime knowledge and workflows that you can update instantly.
|
|
|
|
### What is the difference between Agent Skills and MCP
|
|
|
|
Agent Skills focus on workflows and capabilities, while MCP focuses on secure, structured data and tool access.
|
|
|
|
### How do I create my first Agent Skill
|
|
|
|
See the [How to Build Skills](#how-to-build-skills) section for a step-by-step authoring guide.
|
|
|
|
### Which AI platforms support Agent Skills
|
|
|
|
Support varies by platform, but major tools include Claude (Claude.ai and Claude Code), OpenAI Codex, GitHub Copilot, Cursor, VS Code, and more.
|
|
|
|
### Can I use Agent Skills with ChatGPT or other LLMs
|
|
|
|
If a platform does not support the format natively, you can often integrate skills via a loader or by adapting the `SKILL.md` instructions into that platform's prompt workflow.
|
|
|
|
### Are Agent Skills secure
|
|
|
|
Treat skills like code: review them before using, avoid installing from untrusted sources, and prefer audited skill libraries.
|
|
|
|
### How do I share Agent Skills with my team
|
|
|
|
The most common approach is to version skills in Git (in a shared repo) and let your supported tools discover them from a standard directory.
