How to build per-vertical catalog schema validation for multi-vertical regulated operators

The 4-skill bundle on the catalog-schema-validator agent

One agent. Four coordinated skills. The Validate + Map + Gate + Audit bundle runs above the commerce + marketplace + schema-validation substrate and writes one canonical per- SKU per-marketplace catalog-compliance record.

Compliance overlay

Five anchors run per-SKU per-marketplace before any catalog entry publishes. The first anchor is operationally distinctive: Product + Offer + AggregateRating + Review schema + per-marketplace catalog format + per-vertical FDA + FTC Health Products + DEA + alcohol/ converge on every SKU.

FAQ

What is per-vertical catalog schema validation — and what is the Product-schema-times-per-marketplace-catalog-format-times-per-vertical-FDA-DEA-alcohol-age-restriction problem distinctive to this skill?

A multi-vertical regulated operator with 50,000-2M SKUs across health products + supplements + alcohol + tobacco + + cosmetics + medical devices + food ships product catalog across 8-15 marketplaces (Google Merchant Center + Bing Shopping + Meta Shop Catalog + Amazon Seller Central + Etsy + Walmart Marketplace + TikTok Shop + Pinterest Catalog + Instagram Shop + YouTube Shopping + Google Manufacturer Center). Each marketplace ships its own catalog format spec + restricted-products policy. Each vertical ships its own FDA + FTC + DEA + state-board compliance requirement. The four-skill bundle on the catalog-schema-validator agent — Validate, Map, Gate, Audit — sits above the commerce + marketplace + schema-validation substrate (Shopify + WooCommerce + Magento + BigCommerce + Salesforce Commerce Cloud + commercetools + Saleor + Medusa + Schema App + Yoast + RankMath + Google Rich Results Test + Schema.org Validator + Sitebulb + Screaming Frog + OnCrawl + Botify + Conductor + Ahrefs + SEMrush + Moz Pro) and writes a per-SKU per-marketplace catalog-compliance canonical record. The operationally distinctive anchor: Product + Offer + AggregateRating + Review + ProductGroup + Brand + Manufacturer + Variant schema + per-marketplace catalog format (Google Merchant Center Product Specification + Bing Shopping Feed Spec + Meta Shop Catalog Spec + Amazon Listing Quality + ASIN match + Etsy + Walmart + TikTok Shop Product API + Pinterest Catalog Spec + Instagram Shop API + YouTube Shopping Spec + Google Manufacturer Center Spec) + per-vertical product compliance (FDA Food + FDA Drug + FDA Nutritional Facts + FDA OPDP + FTC Health Products + FTC Fake Review Rule + DEA Controlled Substances + alcohol TTB/TABC/CalABC + state-board + tobacco state-board + supplement DSHEA + cosmetic FDA + medical device FDA + per-state pharmacy board).

Why do Shopify + WooCommerce + Magento + Google Merchant Center + Amazon Seller Central + Schema App + Google Rich Results Test break at multi-vertical-regulated-catalog scale?

Each commerce platform ships per-account flat product-catalog primitive at single-marketplace level. Each marketplace ships its own catalog format spec (Google Merchant Center Product Specification + Bing Shopping Feed Spec + Meta Shop Catalog Spec + Amazon Listing Quality + Etsy + Walmart + TikTok Shop + Pinterest + Instagram + YouTube Shopping). None handles per-vertical FDA + FTC Health Products + DEA + alcohol TTB/TABC/CalABC + state-board + tobacco + supplement DSHEA + cosmetic FDA + medical device FDA convergence on a per-SKU basis. None gates against FTC Fake Review Rule 16 CFR Part 465 ($51,744 per-violation) + per-vertical age-restriction (21+ alcohol/ + 18+ tobacco) + COPPA + per-vertical recall management. None enforces SOX 302/404/906 + COSO + Exchange Act 13(b)(2) when public-company catalog material. None writes a per-SKU per-marketplace catalog-compliance audit trail with regulatory-defense retention. The four-skill bundle Validate + Map + Gate + Audit sits above the commerce + marketplace + schema-validation substrate — it does not replace it.

How does Validate + Map work?

Validate runs per-SKU per-marketplace per-vertical Product + Offer + AggregateRating + Review + ProductGroup + Brand + Manufacturer + ProductCollection + ItemList + Variant schema validation against Schema.org spec + per-marketplace catalog format spec (Google Merchant Center Product Specification + Bing Shopping Feed Spec + Meta Shop Catalog Spec + Amazon Listing Quality + ASIN match + Etsy + Walmart + TikTok Shop Product API + Pinterest Catalog Spec + Instagram Shop API + YouTube Shopping Spec + Google Manufacturer Center Spec) + per-vertical FDA + FTC Health Products + DEA + alcohol TTB/TABC/CalABC + state-board + tobacco + supplement DSHEA + cosmetic FDA + medical device FDA. Per-SKU per-marketplace per-vertical validation result. Map runs per-SKU per-marketplace catalog-format mapping: Shopify-canonical SKU -> Google Merchant Center feed entry + Bing Shopping feed entry + Meta Shop Catalog entry + Amazon ASIN match + Etsy + Walmart + TikTok Shop + Pinterest + Instagram + YouTube Shopping + Google Manufacturer Center. Per-SKU per-marketplace per-vertical field-translation (GTIN + MPN + brand + manufacturer + category + condition + availability + price + sale price + identifier_exists + age_group + gender + size + color + material + pattern + product_type + google_product_category + custom_label). Per-SKU per-marketplace per-vertical restricted-products check (Amazon Restricted Products + Etsy Prohibited + Walmart Restricted + TikTok Shop Prohibited + Pinterest Acceptable Use).

Audit writes a per-SKU per-marketplace WORM catalog-compliance record: SKU snapshot + per-marketplace catalog-format mapping + per-vertical compliance applicability + per-anchor gate-pass + per-marketplace publish-block decision + AI-ML provenance + EU AI Act FRIA. Storage: AWS S3 Object Lock + Azure Blob immutable + GCS + Wasabi WORM.

What does this skill connect to on the catalog-schema-validator agent and across the swarm?

On the catalog-schema-validator agent: catalog-schema-validation (parent commercial pillar) + per-marketplace catalog feed orchestration + per-SKU per-marketplace AI-generated product copy gating + per-SKU product-recall propagation. Across the swarm: continuous schema audit (#596 UPSTREAM canonical of schema-state) + schema auto-remediation (#582 DOWNSTREAM consumer) + rich-result eligibility scoring (#563 UPSTREAM canonical) + integration-drift-monitor agent (#562 + #569 + #570) + tiered pre-filter deterministic gates for AI content + per-vertical compliance overlay + multi-location-seo-architecture (#575 + #579). Commercial-pillar parent: /catalog-schema-validation. Cross-vertical pairing: this skill is the DTC-ecommerce analog to the multi-location LocalBusiness schema-audit cluster (#596 + #582 + #563).

What does the 6-workstream pre-engagement-baseline reporting cycle look like for this skill?

Every two weeks during the Tier 3 Fractional CMO with AI Swarm engagement, six workstreams report against the pre-engagement baseline. Workstream 1: per-catalog per-SKU per-marketplace catalog-compliance coverage — SKUs monitored + marketplaces covered + verticals covered + per-marketplace catalog format absorbed. Workstream 2: Validate per-SKU per-marketplace per-vertical validation flow — Schema.org schema validation + per-marketplace catalog format validation + per-vertical FDA/DEA/alcohol//tobacco/DSHEA validation. Workstream 3: Map per-SKU per-marketplace catalog-format mapping flow — per-SKU per-marketplace field-translation + per-marketplace restricted-products check. Workstream 4: Gate per-SKU per-marketplace publish-block decision flow — per-anchor gate-pass result + per-marketplace policy enforcement + per-vertical age-restriction enforcement. Workstream 5: Regulatory-defense audit coverage — Product/Offer/AggregateRating/Review + per-marketplace catalog format + per-vertical FDA + FTC Fake Review + DEA + alcohol/ + age-restriction + EU AI Act Article 50 + SOX. Workstream 6: FBC feedback-loop pattern-learning — per-SKU per-marketplace realized-vs-predicted catalog-compliance + per-marketplace policy enforcement retrospective + per-vertical recall retrospective.
