Skills at Scale

Write once, run in Claude, Codex, Cursor, and your own agents

An 80-minute hands-on workshop at AIE Europe 2026 by Nick Nisi & Zack Proser.

What You’ll Do

Build one reusable skill — a Repo Roast (repo health assessment) — progressively layering techniques across three acts:

1. Build the foundation — constraints, scripts (! backtick inline execution), structure
2. Make it smarter — phased workflow, confidence scoring
3. Skills beyond the editor — advanced scripts, portability, eval, composition

Quick Start (Attendees)

git clone https://github.com/workos/aie-europe-skills-at-scale.git
cd aie-europe-skills-at-scale
./setup.sh        # installs the starter skill
claude             # or codex, or cursor

Then ask your agent: Roast this repo

Prerequisites

Bring a laptop with Claude Code, Codex, or Cursor.

Sharing Your Skill (Live Workshop)

During the workshop, you can share your skill with the presenter to have it run live on stage:

./share.sh --name "Your Name"

This reads your skill from .claude/skills/repo-roast/SKILL.md and sends it to the workshop server. No accounts, no setup — just run the command.

Running the Slides

cd slides
pnpm install
pnpm dev

Opens at http://localhost:3030. Press P for presenter mode.

Presenter: Reviewing Shared Skills

./review.sh            # list all submitted skills
./review.sh 3          # load skill #3 (backs up your current SKILL.md)
./review.sh --restore  # restore your original skill from backup
./review.sh --clear    # clear all submissions (requires secret)

Clearing Submissions

From the script (uses the API):

./review.sh --clear    # prompts for secret (default: roast-2026)

Directly via curl (e.g. from any machine):

curl -X DELETE https://skill-share.YOURSUBDOMAIN.workers.dev/skills \
  -H "X-Clear-Secret: roast-2026"

Nuclear option — wipe the entire KV store (if the API isn’t cooperating):

cd worker
npx wrangler kv key list --binding SKILLS | npx wrangler kv bulk delete --binding SKILLS

The clear secret is configured in worker/wrangler.toml under [vars].CLEAR_SECRET.

Deploying the Sharing Server

The sharing system uses a Cloudflare Worker with KV storage.

cd worker
npm install
npx wrangler kv namespace create SKILLS   # copy the ID into wrangler.toml
npx wrangler deploy                        # copy the deployed URL into .share-config

Update .share-config in the repo root with the deployed Worker URL. This file is checked into git so attendees get it on clone.

The clear secret is set in worker/wrangler.toml under [vars].
