Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.
Guide for building applications with Apollo Kotlin, the GraphQL client library for Android and Kotlin. Use this skill when: (1) setting up Apollo Kotlin in a Gradle project for Android, Kotlin/JVM, or KMP, (2) configuring schema download and codegen for GraphQL services, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions,
Guide for building GraphQL servers with Apollo Server 5.x. Use this skill when: (1) setting up a new Apollo Server project, (2) writing resolvers or defining GraphQL schemas, (3) implementing authentication or authorization, (4) creating plugins or custom data sources, (5) troubleshooting Apollo Server errors or performance issues.
Generates complete, branded Auth0 Advanced Custom Universal Login (ACUL) screen implementations using the React or Vanilla JS SDK. Use when a developer asks to create, add, or modify ACUL login screens with custom branding, social login, theming, or specific authentication flows. Triggers on requests like "generate a custom login screen", "add a signup screen to my ACUL project", "customize my Auth0 Universal Login with our brand colors", "apply our theme to all ACUL screens", or any task involving Auth0 Universal Login customization with @auth0/auth0-acul-react or @auth0/auth0-acul-js.
Migrates Auth0.swift v2.x integrations to v3.x. Pass a target v3 tag as an argument (e.g. auth0-swift-major-migration 3.0.0-beta.2) to pin a specific version, or omit it to auto-resolve the latest v3 release. Detects the current version, fetches the new SDK's actual source to confirm signatures, audits which Auth0 APIs the project actually uses, and applies only the breaking changes that affect real call sites — nothing else. Builds until green, then summarises what changed.
Upgrade Datadog Browser SDK from v6 to v7. Use when encountering removed options like betaEncodeCookieOptions, allowFallbackToLocalStorage, trackBfcacheViews, usePciIntake, or when a project references datadoghq-browser-agent.com CDN with /v6/ paths.
Configures Flutter Driver for app interaction and converts MCP actions into permanent integration tests. Use when adding integration testing to a project, exploring UI components via MCP, or automating user flows with the integration_test package.
Adds interactive widget previews to the project using the previews.dart system. Use when creating new UI components or updating existing screens to ensure consistent design and interactive testing.
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Add `flutter_localizations` and `intl` dependencies, enable "generate true" in `pubspec.yaml`, and create an `l10n.yaml` configuration file. Use when initializing localization support for a new Flutter project.
