Claude Skills Explained - Step-by-Step Tutorial for Beginners

About this video

Presented by David, who works with Kevin, this tutorial explains Claude Agent Skills for Claude, Claude Desktop and Claude Code. A paid Pro or Team account is required; in Settings > Capabilities you turn on skills such as Skill Creator, Theme Factory, Canvas Design and Artifacts Builder. Built-in skills trigger automatically from a prompt: a PowerPoint skill reads its skill file to build a deck from an outline, and Theme Factory then applies brand colors, patterns and a theme — no custom instructions or Project needed, because the workflow is packaged once and reused anywhere. To create a custom skill, start a new chat and type ‘make a new skill’; Skill Creator asks what workflow it should handle, for concrete trigger examples, and what makes it unique. The example AI FOMO summarizer uses personal context to judge new AI tools, may ask up to three follow-up questions, and the presenter advises asking ‘what else should I clarify?’ before building. After about 45 seconds the skill file is downloaded and installed via Settings > Capabilities > Upload Skill, then tested: it returns a FOMO score of 6 out of 10 and a ‘worth exploring’ recommendation for OpenAI’s Atlas browser. Skills are revised by asking Claude in the creation chat for changes, then re-downloading and re-uploading. Skills can also call MCP servers — examples connect Gmail to summarize unread emails from yesterday and draft replies, and a QuickBooks Online MCP server to summarize monthly finances.
