At a glance

Build standalone Angular components with Signals inputs, OnPush change detection, Control Flow, and Smart/Dumb patterns.

  • Building standalone Angular components
  • SKILL.md covers Priority: P0 (CRITICAL), Standalone & Structure, Signals & Change Detection and Control Flow, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Implementing @if/@for control flow

What it does

Angular Components is an agent skill from HoangNguyen0403/agent-skills-standard. Build standalone Angular components with Signals inputs, OnPush change detection, Control Flow, and Smart/Dumb patterns. Use when building standalone Angular components, implementing @if/@for control flow, applying OnPush change detection, or implementing Signals in Angular components.

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/control-flow.md` and `references/standalone-pattern.md`).

It sits in Data & Analytics, covering Anomaly detection. It works with Angular. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Building standalone Angular components
  • Implementing @if/@for control flow
  • Applying OnPush change detection
  • Implementing Signals in Angular components

Example prompts

  • “/angular-components”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Angular Components loads about 723 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~723
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Angular Components

Priority: P0 (CRITICAL)

Standalone & Structure

  • Standalone: standalone: true. Import all deps in imports array. No NgModule. (Angular 20+: standalone default.)
  • Smart/Dumb Split: Smart (Container) → inject services, manage state. Presentational (Dumb) → accept inputs and emit events via outputs only; no service dependencies.
  • Host Bindings: Define in host: { } on @Component (e.g., '[class.active]': 'isActive()') — never use @HostBinding/@HostListener.
  • View Encapsulation: Default Emulated. Use None carefully.

Signals & Change Detection

  • OnPush: ALWAYS use ChangeDetectionStrategy.OnPush. No exceptions.
  • Signal Inputs: input.required<T>() or input<T>() not @Input(). Access as functions: {{ userId() }}. Use booleanAttribute/numberAttribute transforms.
  • Signal Outputs: output<T>() (v17.3+) not @Output() EventEmitter. Two-way binding: model().
  • State: signal() local, computed() derived, effect() side effects only.
  • Cleanup: toSignal() (auto-unsubscribes), takeUntilDestroyed(), or DestroyRef. Never subscribe() without cleanup.

Control Flow

  • Use @if (condition), @for (item of items; track item.id), @switch, @empty { } instead of *ngIf/*ngFor (new control flow syntax, Angular 17+).

Anti-Patterns

  • No default CD: OnPush only — default re-checks every component every event.
  • No functions in templates: {{ calculate() }} re-evaluates every cycle → computed() instead.
  • No manual subscribe: async pipe or toSignal. Never subscribe() without cleanup.
  • No ElementRef mutation: Directives or Renderer2.
  • No class inheritance: Compose with Directives and Services.

Canonical response anchors

When this skill applies, preserve the following domain terminology or equivalent concrete examples in the answer when relevant:

  • @empty { }

  • Never use @HostBinding

  • Signal inputs

  • inputs and emit events via outputs

  • Additional task-grounded exact anchors: @if (condition); @for (item of items; track item.id); booleanAttribute; model(); Smart (Container); toSignal()
