Modernes Angular-Standalone-Komponenten erstellen nach Best Practices von v20+. Nutzen Sie Signal-basierte Eingänge/Ausgänge, OnPush-Change-Detection, Host-Bindings, Inhaltsprojektion und Lifecycle-Hooks. Auslösen bei der Komponentenerstellung, Refactoring von klassenbasierten zu Signal-Eingängen, Hinzufügen von Host-Bindings oder Implementierung barrierefreier interaktiver Komponenten.
Dieses Skill erstellt moderne, vollständig eigenständige Angular-Komponenten gemäß den Best Practices ab Angular v20+. Es ist ideal für Entwickler, die UI-Komponenten mit signalbasierten Eingängen (Inputs) und Ausgängen (Outputs), OnPush-Change-Detection, Host-Bindings, Inhaltsprojektion (Content Projection) und Lifecycle-Hooks (z.B. `ngOnInit`, `ngAfterViewInit`) bauen wollen. Das Skill wird automatisch ausgelöst, wenn ein Benutzer eine neue Komponente erstellt, eine bestehende Klasse mit `@Input()`-Dekoratoren in die moderne Signal-Syntax (`input.required()`) umwandelt, Host-Bindings (`@HostBinding`) hinzufügt oder barrierefreie, interaktive Komponenten (wie modale Fenster oder Tabs) implementiert. Es unterstützt alle Tools und Plattformen, die Angular CLI und die Standalone-API nutzen, wie z.B. Cursor, Codex oder Claude Code. Die Umsetzung erfolgt gemäß der in der SKILL.md-Dokumentation festgelegten Vorlagen, die die Linting-, Test- und Barrierefreiheitsstandards des Projekts einhalten.

Erstellen Sie moderne Angular-Standalone-Komponenten nach den Best Practices von v20+. Verwenden Sie es zum Bauen von UI-Komponenten mit Signal-basierten Eingängen/Ausgängen, OnPush-Change-Detection, Host-Bindings, Inhaltsprojektion und Lifecycle-Hooks. Es wird ausgelöst bei der Komponentenerstellung, beim Refactoring von klassenbasierten Eingängen zu Signalen, beim Hinzufügen von Host-Bindings oder beim Implementieren barrierefreier interaktiver Komponenten.
This repo contains 9 individual skills — each has its own dedicated page.
Implement dependency injection in Angular v20+ using inject(), injection tokens, and provider configuration. Use for service architecture, providing dependencies at different levels, creating injectable tokens, and managing singleton vs scoped services. Triggers on service creation, configuring providers, using injection tokens, or understanding DI hierarchy.
Create custom directives in Angular v20+ for DOM manipulation and behavior extension. Use for attribute directives that modify element behavior/appearance, structural directives for portals/overlays, and host directives for composition. Triggers on creating reusable DOM behaviors, extending element functionality, or composing behaviors across components. Note - use native @if/@for/@switch for control flow, not custom structural directives.
Build signal-based forms in Angular v21+ using the new Signal Forms API. Use for form creation with automatic two-way binding, schema-based validation, field state management, and dynamic forms. Triggers on form implementation, adding validation, creating multi-step forms, or building forms with conditional fields. Signal Forms are experimental but recommended for new Angular projects. Don't use for template-driven forms without signals or third-party form libraries like Formly or ngx-formly.
Implement HTTP data fetching in Angular v20+ using resource(), httpResource(), and HttpClient. Use for API calls, data loading with signals, request/response handling, and interceptors. Triggers on data fetching, API integration, loading states, error handling, or converting Observable-based HTTP to signal-based patterns.
Implement routing in Angular v20+ applications with lazy loading, functional guards, resolvers, and route parameters. Use for navigation setup, protected routes, route-based data loading, and nested routing. Triggers on route configuration, adding authentication guards, implementing lazy loading, or reading route parameters with signals.
Implement signal-based reactive state management in Angular v20+. Use for creating reactive state with signal(), derived state with computed(), dependent state with linkedSignal(), and side effects with effect(). Triggers on state management questions, converting from BehaviorSubject/Observable patterns to signals, or implementing reactive data flows.
Implement server-side rendering and hydration in Angular v20+ using @angular/ssr. Use for SSR setup, hydration strategies, prerendering static pages, and handling browser-only APIs. Triggers on SSR configuration, fixing hydration mismatches, prerendering routes, or making code SSR-compatible.
Write unit and integration tests for Angular v20+ applications using Vitest or Jasmine with TestBed and modern testing patterns. Use for testing components with signals, OnPush change detection, services with inject(), and HTTP interactions. Triggers on test creation, testing signal-based components, mocking dependencies, or setting up test infrastructure. Don't use for E2E testing with Cypress or Playwright, or for testing non-Angular JavaScript/TypeScript code.
Use Angular CLI and development tools effectively in Angular v20+ projects. Use for project setup, code generation, building, testing, and configuration. Triggers on creating new projects, generating components/services/modules, configuring builds, running tests, or optimizing production builds. Don't use for Nx workspace commands, custom Webpack configurations, or non-Angular CLI build systems like Vite standalone or esbuild direct usage.
Notion CLI/API for pages, Markdown content, data sources, files, comments, search, Workers, and raw API calls.
The agent engineering platform.
Use this skill when the user requests to generate, create, or produce podcasts from text content. Converts written content into a two-host conversational podcast audio format with natural dialogue.
Analyze and optimize tweets for maximum reach using Twitter's open-source algorithm insights. Rewrite and edit user tweets to improve engagement and visibility based on how the recommendation system ranks content.
Extracts and analyzes competitors' ads from ad libraries (Facebook, LinkedIn, etc.) to understand what messaging, problems, and creative approaches are working. Helps inspire and improve your own ad campaigns.
