## What it does

This skill directs AI assistants to follow official Angular, SASS, and TypeScript style conventions. It instructs the model to create standalone components, inject dependencies via the `inject` function, and handle reactivity through Angular signals. Every file follows kebab-case naming with explicit suffixes like `.component.ts` or `.service.ts`.

Template recommendations focus on rendering efficiency. The agent applies deferrable views, utilizes `NgOptimizedImage`, and supplies `trackBy` functions for `ngFor` loops. Because the rules ban `any` completely, the agent will rewrite untyped data into explicit interfaces across your services.

Security standards restrict direct DOM access and forbid `innerHTML` to prevent XSS. For tests, the skill mandates `.spec.ts` files structured around the Arrange-Act-Assert pattern. Code style stays consistent with 2-space indentation and single quotes.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill angular -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/angular/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/angular/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill angular -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/angular/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill angular -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/angular/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills angular
```

2. **Manually: put the files in place**
- File: `.github/skills/angular/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill angular -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path angular
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/angular/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill angular -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- Refactor state management to Angular signals and the inject function
- Enforce interface-based data models while eliminating the any type
- Speed up template rendering using NgOptimizedImage and trackBy
- Generate unit tests formatted with the Arrange-Act-Assert pattern

## Example prompts
- Generate a standalone user profile component using signals and the inject function
- Refactor this list view to use trackBy and deferrable views
- Create a typed authentication service with custom error types and no any

# Angular

You are an Angular, SASS, and TypeScript expert creating scalable, high-performance web applications with strict type safety and Angular's official style guide adherence.

## Core Principles

- Provide concise, precise examples with clear explanations
- Apply immutability and pure functions throughout services and state management
- Favor component composition over inheritance for enhanced modularity
- Use descriptive naming conventions (e.g., `isUserLoggedIn`, `fetchData()`)
- Enforce kebab-case file naming with appropriate suffixes

## TypeScript Standards

- Define data models using interfaces; avoid `any` type entirely
- Structure files with imports first, followed by class definition, properties, methods
- Leverage optional chaining (`?.`) and nullish coalescing (`??`) operators
- Use standalone components appropriately for code reusability
- Utilize Angular's signals system for efficient reactive state management
- Employ the `inject` function for direct service injection

## File Organization

- Components: `*.component.ts`
- Services: `*.service.ts`
- Directives: `*.directive.ts`
- Pipes: `*.pipe.ts`
- Tests: `*.spec.ts`

## Code Standards

- Single quotes for string literals
- 2-space indentation
- Prefer `const` for immutable variables
- Use template literals for interpolation

## Angular-Specific Guidelines

- Use `async` pipe for observable subscriptions in templates
- Enable lazy loading for feature modules
- Ensure accessibility with semantic HTML and ARIA attributes
- Implement deferrable views for non-essential components
- Use `NgOptimizedImage` for efficient image loading
- Apply trackBy functions with `ngFor` for optimized rendering

## Performance Optimization

- Optimize list rendering with trackBy functions
- Use pure pipes for computationally heavy operations
- Avoid direct DOM manipulation; rely on Angular's templating engine
- Leverage signals to reduce unnecessary re-renders
- Focus on Web Vitals optimization (LCP, INP, CLS)

## Error Handling & Security

- Implement robust error handling with custom error types
- Use Angular's form validation system for input validation
- Prevent XSS through Angular's sanitization; avoid `innerHTML`
- Follow Arrange-Act-Assert pattern for unit tests
```
