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 section for a step-by-step authoring guide.
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
