Can I use Claude-specific features with this standard?

Yes, while the standard defines a portable subset, Claude Code supports extensions for advanced features like hooks, context forks, and specific model selection.

What is the Agent Skills Open Standard?

It is a standardized format for extending AI agent capabilities using specialized knowledge and workflows, structured as a directory with a mandatory SKILL.md file and optional scripts or references.

How does progressive disclosure benefit AI performance?

It manages context efficiently by only loading metadata at startup, activation instructions when needed, and deep resources on demand, preventing the AI's context window from being overwhelmed.

Are there specific naming rules for Agent Skills?

Yes, skill names must be 1-64 characters, use only lowercase alphanumeric characters and hyphens, and must exactly match the parent directory name.

Which agents are compatible with these skills?

The standard is supported by over 25 products, including Anthropic's Claude Code, Cursor, Gemini CLI, OpenAI Codex, VS Code, and Roo Code.
