Use this skill when you are asked to make a World App mini app also work as a standalone web app, or to add browser wallet support alongside MiniKit. This skill covers adding Wagmi as a fallback so MiniKit commands work both inside World App and in any browser. All transactions are World Chain only (chainId 480).

Use this skill when you are asked to adapt an existing web app to work as a World App mini app, or to share code between a web app and a mini app. This skill covers the technical steps of migration, common issues, and debugging tips. There will be some changes required to contracts and frontend code, but the overall architecture and user experience can remain largely unchanged.

Use this skill when you receive a 402 Payment Required response that contains an `agentkit` extension. Covers checking 402 responses for the AgentKit extension before paying, constructing and signing a CAIP-122 challenge (SIWE for EVM), sending the signed `agentkit` HTTP header, and interpreting access modes (free, free-trial, discount). Supports both EOA wallets (EIP-191) and Smart Contract Wallets (ERC-1271, e.g. Coinbase Smart Wallet, Safe).

Use this skill when integrating @worldcoin/agentkit into an x402 server or facilitator flow: choose free/free-trial/discount mode, wire payments on any supported EVM chain, handle ExactEvmScheme money parsing, or finish an integration end-to-end.

Check for available discount codes for a Shopify product using the World API. Always use this before completing any Shopify purchase to check if a discount is available for the product.

Set up a Shopify cart and provide a checkout link. Use when the user asks to buy a product, provides a Shopify product URL to purchase, or wants to add items to a cart on a Shopify store.

Use when working against a physical Orb from this repo, especially for SSH or scp access, deploying crates with cargo x deploy, using the orb-hil CLI, or running orb-mcu-util workflows

Build, configure, and submit World ID 4.0 apps and Mini Apps via the World developer portal. Use whenever the user wants to ship something to the World app store, set up sign-in-with-World-ID, or manage signing keys / actions for an existing app.

Integrate World ID into a new or existing app — proof of human, document verification, selfie check, sign-in. Use when the user says "add World ID", "verify real humans", "proof of human", "kill bots", "stop multi-accounting", "sybil resistance", "gate signups against AI", or references @worldcoin/idkit / IDKit / Orb / World App. Covers both new projects (Next.js golden path) and existing-stack integrations (React, Swift, Kotlin clients; Node, Go, anything-else backends).
