Anthropic has introduced Claude Skills, a new feature that allows users to create and share skills, which are folders containing instructions, scripts, and resources that Claude can load when needed to improve its performance on specific tasks. Skills are conceptually simple, consisting of a Markdown file with optional scripts and documents, and can be easily shared and used with other models. The author believes that Skills have the potential to be a bigger deal than Model Context Protocol (MCP) due to their simplicity and flexibility. Skills can be used to automate tasks, such as data journalism, and can be easily iterated upon to improve their performance.
