Summary
Claude Skills are specialized folders containing instructions, scripts, and resources that enable Claude to perform repeatable tasks across its products, from the web interface to Claude Code CLI to the API.
They use progressive disclosure architecture to load metadata first (~100 tokens), then full instructions (<5k tokens) only when relevant, allowing multiple Skills to remain available without overwhelming the context window. The repository provides official Skills for documents (Word, PDF, PowerPoint, Excel), design, development, and communication, plus community-contributed Skills ranging from iOS app testing to security analysis, with tools for creating custom Skills tailored to specific workflows.
