Skills at Scale

Resources from the hands-on workshop Zack Proser and I ran on writing portable AI skills. Let’s connect on LinkedIn and BlueSky.

Presented at AI Engineer Europe 2026

Abstract

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 — a markdown file 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 the WorkOS 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 AuthKit in under 60 seconds. That’s not a demo. That’s production code, shipping today.

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

What you’ll leave with

• Working skills installed in your AI tools, ready to use Monday morning
• A repeatable pattern for turning any recurring task into a portable skill
• The mental model for when a skill is enough and when you need a full agent
