title: 'Full Walkthrough: Writing & Using Skills — Nick Nisi and Zack Proser'
description: >-
  Write once, run in Claude, Codex, Cursor, and your own agents Every developer
  using AI tools has the same problem: they prompt the same way, for the same
  tasks, over and over. Skills fix this. A skill is a portable unit of agent
  behavior that teaches any AI tool how to do a specific job. Write one, drop it
  into your editor, and it just works. Across tools. Across teams. Most people
  don't know this primitive exists. In this hands-on workshop, you'll write real
  skills, test them live, and see how one file can power Claude.ai, Claude Code,
  Cursor, and Codex without changing a line. Then we'll go deeper. You'll see
  how one CLI uses this same pattern to power 15 framework integrations — each
  one a skill composed with others, wired into an agent that installs and
  configures auth! What you'll do: Write 2+ skills for tasks you actually do at
  work Install and test them across AI tools in real time Learn the craft of
  good skill writing — specificity, constraints, composability See how skills
  compose and scale inside a real CLI powered by the Claude Agent SDK Speaker
