Agent Skills are folders of instructions, scripts, and resources that Claude loads dynamically to improve performance on specialized tasks.
Think of them as onboarding guides that transform Claude from a general assistant into a domain expert — whether creating documents, analyzing data, or automating workflows.
"Skills extend Claude's capabilities by packaging your expertise into composable resources… transforming general-purpose agents into specialized agents that fit your needs."
