The article emphasizes the importance of understanding the difference between Claude Skills and prompts, as treating Skills like prompts can lead to inefficiencies. A Skill, as defined by Anthropic, is a reusable capability that allows Claude to remember context and workflows across multiple interactions, unlike a prompt which only triggers a one-time response. The author illustrates this distinction using the example of a Skill created by Zara Zhang, called Frontend Slides, which automates the creation of interactive HTML presentations. This Skill asks for specific context before generating slides, eliminating the need for users to repeat instructions in every session. The article also outlines three ways to use Skills: utilizing built-in Skills that come with Claude, installing third-party Skills from platforms like GitHub, and creating custom Skills with Claude's assistance. This approach not only saves time but also enhances the overall user experience by ensuring that Claude operates with the necessary context and instructions.
