Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
OpenAISkillopenai/plugins/plugins/shopify/skills/shopify-polaris-admin-extensions/SKILL.md
Add custom actions and blocks from your app at contextually relevant spots throughout the Shopify Admin. Admin UI Extensions also supports scaffolding new adminextensions using Shopify CLI commands.
OpenAISkillopenai/plugins/plugins/shopify/skills/shopify-polaris-app-home/SKILL.md
Build your app's primary user interface embedded in the Shopify admin. If the prompt just mentions `Polaris` and you can't tell based off of the context what API they meant, assume they meant this API.
OpenAISkillopenai/plugins/plugins/shopify/skills/shopify-polaris-checkout-extensions/SKILL.md
Build custom functionality that merchants can install at defined points in the checkout flow, including product information, shipping, payment, order summary, and Shop Pay. Checkout UI Extensions also supports scaffolding new checkout extensions using Shopify CLI commands.

OpenAISkillopenai/plugins/plugins/shopify/skills/shopify-storefront-graphql/SKILL.md
Use for custom storefronts requiring direct GraphQL queries/mutations for data fetching and cart operations. Choose this when you need full control over data fetching and rendering your own UI. NOT for Web Components - if the prompt mentions HTML tags like <shopify-store>, <shopify-cart>, use storefront-web-components instead.
OpenAISkillopenai/plugins/plugins/shopify/skills/shopify-use-shopify-cli/SKILL.md
Choose when the user needs **Shopify CLI** to run or fix something now: validate app or extension config on disk (`shopify.app.toml`, `shopify.app.<name>.toml`, `shopify.extension.toml`); run or troubleshoot store workflows (`shopify store auth`, `shopify store execute`); inventory or product changes by handle, SKU, or location name; or CLI setup, auth, upgrade issues. Emphasize **commands and operational steps**, not only authoring GraphQL. Skip for API-only understanding or codegen with no CLI execution. Examples: validate configuration before deploy; run an existing query via CLI; list products; missing `shopify store execute`.
OpenAISkillopenai/plugins/plugins/shopify/skills/ucp/SKILL.md
Use when the user wants to use the UCP CLI to find, compare, buy, or track products from online merchants, or to set up and troubleshoot the local UCP profile required for merchant-scoped operations. Covers global catalog search (\"find me X under $Y\"), named-merchant transactions (\"buy this from Z.com\"), order tracking, `ucp profile init`, `ucp doctor`, carts, checkout, orders, and UCP setup/help. Falls back to merchant-hosted handoff when direct in-protocol checkout isn't available.
OpenAISkillopenai/plugins/plugins/stripe/skills/connect-recommend/SKILL.md
Use this skill when the user asks about Stripe Connect configuration, charge patterns, Dashboard access, or how to get started with Connect, is building a marketplace, platform, multi-vendor store, gig platform, or subscription platform, needs to pay out sellers, vendors, or providers, mentions split payments, revenue sharing, multi-party payments, or similar payment distribution concepts, provides a company URL or business description for a recommendation, builds SaaS that routes money between parties (for example, POS, booking, invoicing — not operational SaaS without payment routing), asks about onboarding or KYC for merchants, sellers, and vendors, mentions connected account Dashboard or responsibility configurations, or asks about payment flows, white-label payments, or embedded payments.
OpenAISkillopenai/plugins/plugins/stripe/skills/stripe-apps/SKILL.md
Use when building, modifying, or reviewing a Stripe App — or when the user describes something that implies one (e.g. "add a panel to the customer page", "customize my Stripe Dashboard", "react to Stripe events from my app", "connect my service to Stripe without sharing API keys"). Covers the full app development workflow (scaffold, preview, upload, versioning), UI extension architecture (sandboxed iframe, Stripe UI toolkit, viewports), extension types (UI extensions, backend-only, extension interfaces, embedded apps), authentication (platform keys, OAuth, restricted API keys), stripe-app.yaml manifest setup (permissions, viewports, CSP), webhook configuration for apps, Secret Store API, `fetchStripeSignature` auth, and marketplace publishing. Use when the user mentions Stripe Apps, UI extensions, @stripe/ui-extension-sdk, stripe-app.yaml, Dashboard extensions, or customizing the Stripe Dashboard.
OpenAISkillopenai/plugins/plugins/stripe/skills/stripe-best-practices/SKILL.md
Guides Stripe integration decisions across API selection (Checkout Sessions vs PaymentIntents), Connect platform setup (Accounts v2, controller properties), billing/subscriptions, tax and registrations (Stripe Tax, automatic_tax, product tax codes), Treasury financial accounts, integration options (Checkout, Payment Element), migrating from deprecated Stripe APIs, and security best practices (API key management, restricted keys, webhooks, OAuth). Use when building, modifying, or reviewing any Stripe integration, including accepting payments, building marketplaces, integrating Stripe, processing payments, setting up subscriptions, collecting sales tax, VAT, or GST, creating connected accounts, or implementing secure key handling.
OpenAISkillopenai/plugins/plugins/stripe/skills/stripe-directory/SKILL.md
Use when the user wants to find businesses, software, service providers, or partners for a specific industry, workflow, pain point, capability, or job to be done. Also use when the agent needs to programmatically purchase or consume a service. Use Stripe Directory to build a short relevant shortlist, even if the user does not mention Stripe Directory explicitly.
OpenAISkillopenai/plugins/plugins/stripe/skills/stripe-docs/SKILL.md
Use when the user or agent needs to read, search, or look up Stripe documentation or API reference. Prefer this over curl or WebFetch for any docs.stripe.com content.
OpenAISkillopenai/plugins/plugins/stripe/skills/upgrade-stripe/SKILL.md
Guide for upgrading Stripe API versions and SDKs
OpenAISkillopenai/plugins/plugins/supabase/skills/supabase-postgres-best-practices/SKILL.md

OpenAISkillopenai/plugins/plugins/supabase/skills/supabase/SKILL.md

OpenAISkillopenai/plugins/plugins/superpowers/skills/brainstorming/SKILL.md

OpenAISkillopenai/plugins/plugins/superpowers/skills/dispatching-parallel-agents/SKILL.md

Use when implementation is complete, all tests pass, and you need to decide how to integrate the work
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
