Onboarding Site Integration with nexus-service

Problem

The onboarding site and nexus-service are disconnected. A vendor can register and configure its marketplace in the onboarding site, but there's no path from there to a live, negotiable marketplace. The two subsystems don't talk to each other.

Background: Marketplaces

A marketplace is a vendor's product line — the set of products and pricing tiers it offers for negotiation. The marketplace ID, not the vendor ID, is the key identifier because a single vendor can operate multiple marketplaces. For example, an energy company might have one marketplace for residential electricity plans and another for business gas contracts, each with its own products, tiers, and eligibility conditions. The marketplace is the unit that gets embedded on a vendor's website and that a buyer agent negotiates against.

Methodology

The task

Each competitor received the same prompt: the problem statement + quick start statements of monocrate's README (~1,500 characters). No "how it works", no source code, no implementation hints. The instructions in the prompt were:

Below is the readme file of a new publishing tool for nodejs monorepos. I want to turn it 
into a full high-quality open source typescript repo to be pushed to github, published 
to npm, announced on hackernews, and become a successful, reliable devtool.

you are a principal engineer (world class understanding of coding, crafts, typescript, open source ecosystem) and we are in an office hour where you consult other projects.

Zod v4 Migration Guide

I made Claude Code suffer through migrating a production monorepo with 131 packages to Zod v4, then made it document everything.

Consider this your cheat sheet—all the breaking changes, gotchas, and fixes you need, battle-tested on mission-critical code.
