Presented by CodexEurope’s first agent skill hackathonOne evening. One mission: use Codex to build a reusable agent skill that does a real go-to-market job - and the evals that prove it works.An agent skill is a reusable set of instructions that teaches a coding agent to perform a specific job reliably. At GTM Skillathon, you’ll turn a GTM workflow into a skill you can run with Codex, improve over time, and share with others.We’ll begin with a live Codex workflow demo. Then you’ll build, evaluate, and demo your own skill before the night ends.GTM is full of jobs waiting to become skills.Pick your battlegroundDominate AI search: Help companies appear in the answers people now ask AI models for.Build 1:1 growth engines: Create outreach or onboarding that adapts to each account in real time.Detect churn early: Catch the signals that a customer may leave before the cancellation email arrives.Create synthetic ICP twins: Test positioning and messaging against simulated buyers.Put virality on autopilot: Build product-led loops that identify and act on growth opportunities.Orchestrate your GTM agents: Create the skill that helps every other GTM agent work as one system.Or bring your own GTM problem.Who it’s forFounders, engineers, growth people, and marketers.You don’t need to have built an agent skill - or used Codex - before. You only need a real problem you want to automate.Come with a problem. Leave with a working skill and evidence that it works.What to bringA laptopA chargerA GTM problem worth solvingWhatever coding agent you already useWe’ll show you the complete skill-building and evaluation workflow in Codex at the event.Schedule17:00 — Doors and check-in
