At a glance

Build custom Angular attribute directives, HostDirectives, and pure pipes.

  • Angular directive
  • SKILL.md covers Priority: P2 (MEDIUM), Principles, Guidelines and Anti-Patterns, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Pipe implementation

What it does

Angular Directives Pipes is an agent skill from HoangNguyen0403/agent-skills-standard. Build custom Angular attribute directives, HostDirectives, and pure pipes. Use for Angular directive or pipe implementation, including custom attribute directives; defer React/CSS middleware and unrelated framework work.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/composition.md`).

It works with Angular and React. 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

  • Angular directive
  • Pipe implementation
  • Including custom attribute directives
  • Defer React/CSS middleware and unrelated framework work

Example prompts

  • “/angular-directives-pipes”

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 Directives Pipes loads about 591 tokens when it runs, and up to ~726 if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~591
With references · SKILL.md plus every file in references/, read only if the agent opens them
~726

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.

Directives & Pipes

Priority: P2 (MEDIUM)

Principles

  • Composition: Use hostDirectives: [TooltipDirective] on @Component or @Directive decorators to compose behaviors without inheritance. Expose inputs/outputs via hostDirectives: [{ directive: TooltipDirective, inputs: ['text'] }].
  • Pure Pipes: Decorate with @Pipe({ name: 'truncate', standalone: true, pure: true }). Implement PipeTransform with transform(value: string, limit = 50) method. Pipes must pure: true (default) to cache results by input reference — Angular only re-runs them when reference changes. ** not set pure: false** unless handling Observables/Arrays that mutate.
  • Directive Logic: Encapsulate reusable DOM manipulation or behavioral logic in standalone: true Directives (e.g., selector: '[appHighlight]'). Inject ElementRef/Renderer2 for DOM access.

Guidelines

  • Signal Inputs: Directives and Pipes support signal inputs.
  • Standalone: All Pipes and Directives must standalone. ** not declare in NgModule**; import directly in component imports array. Use ng generate directive to scaffold.

Anti-Patterns

  • No @HostBinding/@HostListener: Use host: {} object in @Directive decorator — not with @HostBinding or @HostListener (e.g., '(mouseenter)': 'show()', '[attr.aria-label]': 'text()') — these decorators deprecated patterns.
  • No impure pipes for static transforms: Keep pure: true (default); use async pipe for Observables.
  • No structural directives for conditionals: Use native @if/@for/@switch block syntax.
