Claude Code Tutorial: How to Create & Use Custom Skills
In this video, we explore Agent Skills, a standardized way to give AI coding agents (like Claude Code, Cursor AI, and Codex) specific capabilities on demand. Instead of loading every rule at once, Skills allows the agent to load instructions, scripts, and assets only when they are actually needed for the task at hand.
We walk through how to find existing skills, how to install them via the Anthropic marketplace, and how to write your own custom skills to automate your workflow.
