Claude Code skills for building Sitecore Marketplace apps — scaffolding, SDK integration, Blok UI, and deployment
LABSCO SUMMARY
Summary
Seven skills that walk one specific build end to end — scaffolding, wiring the SDK, building UI, and deploying a Sitecore Marketplace app — and nothing outside that path.
Together they cover the whole lifecycle: marketplace-scaffold asks about architecture, auth, and optional packages before running the matching npx shadcn@latest add setup; marketplace-sdk-reference is the API reference across all three SDK packages (client, xmc, ai); marketplace-build-component works in Blok, Sitecore's own shadcn-based design system; marketplace-deploy ships the app to Vercel with the CSP headers a Marketplace iframe needs; marketplace-add-extension adds one of five extension-point types; marketplace-add-xmc wires in XM Cloud's Sites, Pages, Authoring, Content Transfer, Search, and Agent APIs; and marketplace-add-ai adds the Brand Review API for text, image, or document input.
This is for a developer building specifically a Sitecore Marketplace app on SDK v0.4 against a Next.js App Router project, deploying to Vercel — the README states that target stack directly. Anyone doing other Sitecore work (classic CMS templates, XM Cloud outside the Marketplace SDK) gets nothing from vercel-labs/sitecore-skills; this is one vertical done completely rather than a wide surface done thinly.
READ THE FULL ANALYSIS
Who wrote it, and its shelf life. This comes from Vercel Labs, Vercel's own experimental team, not from Sitecore — it is third-party tooling for someone else's product, and it is pinned to SDK v0.4 by name. The README makes no maintenance commitment beyond the current version, so a Sitecore SDK major bump is the kind of change this package would need someone to notice and update for.
What it costs to start. One skill (the SDK reference) is pure documentation with nothing to install. Most of the rest need a local project and toolchain already in place to scaffold, build, or deploy into. Two of the seven — the XM Cloud and Brand Review integrations — need their own account credentials on top of that.

Creating it, placing it in Sitecore
marketplace-add-extension
A Sitecore Marketplace app can show up in several places inside Sitecore — beside a content field, as a tile on the dashboard, in a side panel, or as a full page — and this builds the starting page for whichever one you pick.
marketplace-scaffold
Creates the starting project for an app that runs inside Sitecore, after asking whether it needs a server side of its own, how people will sign in, and which Sitecore data it will touch.
Reaching Sitecore's content and its AI
marketplace-add-ai
Marketing copy, an image or a PDF can be checked against the brand guidelines automatically; this is the wiring that connects a Sitecore app to the service that does the checking.
marketplace-add-xmc
Opens the content side of Sitecore up to an add-on: which sites and pages exist, editing them, searching them, and moving content from one environment to another.
marketplace-sdk-reference
The lookup desk for Sitecore's Marketplace toolkit — which call does what, which of the three packages it lives in, and a TypeScript example to copy.
Screens, and getting it live
marketplace-build-component
Sitecore publishes its own set of buttons, cards and form controls; building an add-on's screens out of those makes it look like part of the product rather than something bolted on, and keeps each screen inside the space it is given.
marketplace-deploy
Puts a finished Sitecore add-on online on Vercel and tells Sitecore where to find it — including the one header setting without which Sitecore refuses to display it at all.
No skill in this package matches that.
