angular-signals は何をしますか？
Angular v20+ でシグナルベースのリアクティブ状態管理を実装します。signal() による状態作成、computed() による派生状態、linkedSignal() による依存状態、effect() による副作用を利用します。状態管理に関する質問、BehaviorSubject/Observable パターンからシグナルへの変換、またはリアクティブデータフローの実装時にトリガーされます。
Angular v20+ でシグナルベースのリアクティブ状態管理を実装します。 signal() による状態作成、computed() による派生状態、linkedSignal() による依存状態、effect() による副作用に対応し、BehaviorSubject/Observable パターンからシグナルへの移行やリアクティブデータフロー実装の質問に応答します。
このスキルは、Angular v20 以降のアプリケーションにおいて、シグナル（Signal）を用いたリアクティブな状態管理を支援します。従来の RxJS の BehaviorSubject や Observable を用いたパターンから、より宣言的で簡潔なシグナルベースのパターンへの移行を容易にします。具体的には、`signal()` による可変状態の作成、`computed()` による派生状態の定義、`linkedSignal()` による他のシグナルへの同期、`effect()` による副作用の管理といった、Angular シグナルの主要な API を活用したコードの実装をガイドします。状態管理に関する質問や、リアクティブデータフローの実装において自動的にトリガーされ、開発者が効率的にシグナルを導入できるよう支援します。対応プラットフォームは主に Angular CLI を用いたウェブアプリケーション開発です。

This repo contains 9 individual skills — each has its own dedicated page.
Create modern Angular standalone components following v20+ best practices. Use for building UI components with signal-based inputs/outputs, OnPush change detection, host bindings, content projection, and lifecycle hooks. Triggers on component creation, refactoring class-based inputs to signals, adding host bindings, or implementing accessible interactive components.
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 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.
Send and manage iMessages via BlueBubbles, including attachments, tapbacks, edits, replies, and groups.
Control Eight Sleep pods (status, temperature, alarms, schedules).
BluOS CLI (blu) for discovery, playback, grouping, and volume.
Create, search, and manage Bear notes via grizzly CLI.
Capture frames or clips from RTSP/ONVIF cameras.
Search GIF providers with CLI/TUI, download results, and extract stills/sheets.
