  • Tasks that involve Design patterns
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Android Architecture is an agent skill from Moustachauve/WLED-Android. Expert guidance on setting up and maintaining a modern Android application architecture using Clean Architecture and Hilt. Use this when asked about project structure, module setup, or dependency injection.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Design patterns. It works with Android and Kotlin. The repository describes itself as: Native Android application for WLED. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Design patterns

Example prompts

  • “/android-architecture”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. High-Level Layers
  2. Dependency Injection with Hilt
  3. Modularization Strategy
  4. Checklist for implementation

What it can do on your machine

Read from SKILL.md and the folder at commit 7e164a8. 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

Android Architecture loads about 757 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~757

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.

Android Modern Architecture & Modularization

Instructions

When designing or refactoring an Android application, adhere to the Guide to App Architecture and Clean Architecture principles.

1. High-Level Layers

Structure the application into three primary layers. Dependencies must strictly flow inwards (or downwards) to the core logic.

  • UI Layer (Presentation):
    • Responsibility: Displaying data and handling user interactions.
    • Components: Activities, Fragments, Composables, ViewModels.
    • Dependencies: Depends on the Domain Layer (or Data Layer if simple). Never depends on the Data Layer implementation details directly.
  • Domain Layer (Business Logic) [Optional but Recommended]:
    • Responsibility: Encapsulating complex business rules and reuse.
    • Components: Use Cases (e.g., GetLatestNewsUseCase), Domain Models (pure Kotlin data classes).
    • Pure Kotlin: Must NOT contain any Android framework dependencies (no android.* imports).
    • Dependencies: Depends on Repository Interfaces.
  • Data Layer:
    • Responsibility: Managing application data (fetching, caching, saving).
    • Components: Repositories (implementations), Data Sources (Retrofit APIs, Room DAOs).
    • Dependencies: Depends only on external sources and libraries.
2. Dependency Injection with Hilt

Use Hilt for all dependency injection.

  • @HiltAndroidApp: Annotate the Application class.
  • @AndroidEntryPoint: Annotate Activities and Fragments.
  • @HiltViewModel: Annotate ViewModels; use standard constructor injection.
  • Modules:
    • Use @Module and @InstallIn(SingletonComponent::class) for app-wide singletons (e.g., Network, Database).
    • Use @Binds in an abstract class to bind interface implementations (cleaner than @Provides).
3. Modularization Strategy

For production apps, use a multi-module strategy to improve build times and separation of concerns.

  • :app: The main entry point, connects features.
  • :core:model: Shared domain models (Pure Kotlin).
  • :core:data: Repositories, Data Sources, Database, Network.
  • :core:domain: Use Cases and Repository Interfaces.
  • :core:ui: Shared Composables, Theme, Resources.
  • :feature:[name]: Standalone feature modules containing their own UI and ViewModels. Depends on :core:domain and :core:ui.
4. Checklist for implementation
  • Ensure Domain layer has no Android dependencies.
  • Repositories should default to main-safe suspend functions (use Dispatchers.IO internally if needed).
  • ViewModels should interact with the UI layer via StateFlow (see android-viewmodel skill).
