How to Create Claude Code Agent Skills in 2026 | Code with Beto

Every time you re-explain the same context to Claude, you're wasting time you could save with a skill: a markdown file in that Claude Code picks up automatically when the task matches. I create skills from scratch in the video, including one that explained a full production app (Inkigo) with a data flow diagram, and a generator that writes new skills for you.

Once you build your first one, you'll start spotting skill-shaped tasks everywhere.
