This official skill from Amazon Selling Partner helps a Fulfilled by Amazon seller stay ahead of stockouts. It pulls current FBA inventory and sales through the Selling Partner API MCP tools, works out days of cover for each SKU, checks whether inbound shipments will arrive in time and suggests what to restock first. Any write action, such as a price change to slow sales, is drafted for your approval and never applied silently. It needs an Amazon seller account connected through the Selling Partner MCP, and it is not for listings, advertising or order fulfillment.
Diagnose Amazon Ads ACOS and plan one testThis skill helps an agent work out why an Amazon Ads campaign's ACOS is high and what single change to test next. It starts from the goal of the campaign, locks the scope of the data, and recalculates CTR, CPC, conversion rate, order value, ACOS, ROAS and TACOS with a bundled script instead of trusting a report's own numbers. It then traces the problem to bids, conversion, order value or traffic mix and judges profit using contribution margin rather than gross margin. By default it only reads and drafts, and any change to bids, budgets or targets needs approval for each object.CommerceAmazon advertisingEcommerce analytics
Cut return rates for an online storeNexscope's skill helps an online seller look into why products come back and lower the return rate. It compares your rate with category benchmarks, digs into return reasons, and suggests changes to the returns policy, the reverse-logistics process and product listings such as size guides and photos. It also works out what returns cost and how to keep customers after a return. It asks one round of follow-up questions, then gives a summary with ranked actions, marking estimates made on thin data.CommerceEcommerce
Find what separates people who convert in a PostHog funnelPostHog's analyzing-funnel-correlation skill helps an agent explain why people finish or abandon a funnel. It splits everyone who entered the funnel into those who completed it and those who did not, then measures which events and person properties go with each outcome using odds ratios written in HogQL. It checks its totals against the funnel itself first and reports the strongest signals on both sides with counts. It reminds you that correlation does not prove cause and suggests testing strong signals with an experiment.Commerceproduct analyticsPostHog
Audit a Shopify store for accessibility and blame theme or appThis skill checks a Shopify store's live pages against the WCAG 2.2 AA standard, pairing automated scanners (pa11y, which runs two rule engines, plus Lighthouse if wanted) with the agent's own review of what scanners cannot judge. It first confirms the site is on Shopify, samples pages by theme template, and assigns every failure to either the theme or the app that injected it, such as a reviews or email widget. The result is a ranked report with concrete fixes, and tasks in your tracker if you ask. It never claims compliance from a clean scan, marks unchecked criteria as undetermined, and does not edit code unless asked.CommerceWeb accessibilityShopify
Audit a product feed for Shopping and catalog ad problemsThis skill audits ecommerce product feed exports, Google Merchant Center diagnostics, catalog screenshots and sample product pages for data problems that can hurt Shopping ads, catalog ads or product approvals. You give it a feed sample, any diagnostics and the affected product URLs, and it checks fields such as titles, prices, availability, images, GTINs and categories for Google Shopping, Meta, TikTok or marketplace catalogs. Use it when products are disapproved, when Shopping results drop without a clear campaign cause, or before pushing a catalog to a new channel. You get a list of feed issues and what to fix.Commerce
Build ecommerce storefronts with Medusa best practicesThis skill gives an agent best-practice guidance for building online store front ends, including checkout, cart, product pages, navigation and SEO. It tells the agent to load the right reference file for each task, check existing design choices before adding any component, and fetch categories, products and prices from the backend instead of hard-coding them. It covers connecting to a Medusa backend and making a store readable by shopping agents, with server-rendered prices and a plain add-to-cart form. It works with Next.js, SvelteKit, React, Vue and similar frameworks.CommerceEcommerceStorefront development
