What it does

Abp Core is an agent skill from abpframework/abp. Core ABP Framework conventions - module system, DI registration, base classes (ApplicationService, DomainService), IClock, BusinessException, localization, async patterns. Use when working on any ABP project, asking about ABP fundamentals, or unsure which skill applies.

Its SKILL.md is about 1.7k 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 Frontend & Design, covering Internationalization. The repository describes itself as: Open-source web application framework for ASP.NET Core! Offers an opinionated architecture to build enterprise software solutions with best practices on top of the .NET. Provides… The licence is LGPL-3.0.

Example prompts

“/abp-core”

What it can do on your machine

Read from SKILL.md and the folder at commit a54b599. 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 (its code samples are csharp and json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- abp.io
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

Abp Core loads about 1.7k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 450 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~70
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

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.

ABP Core Conventions

Documentation: https://abp.io/docs/latest API Reference: https://abp.io/docs/api/

Key Rules

Use IClock / Clock.Now instead of DateTime.Now / DateTime.UtcNow
Use ITransientDependency / ISingletonDependency instead of AddScoped/AddTransient/AddSingleton
Use IRepository<T> instead of injecting DbContext directly
Check base class properties (Clock, CurrentUser, GuidGenerator, L) before injecting services
Use BusinessException with namespaced error codes for domain rule violations

Module System

Every ABP application/module has a module class that configures services:

csharp

[DependsOn(
    typeof(AbpDddDomainModule),
    typeof(AbpEntityFrameworkCoreModule)
)]
public class MyAppModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        // Service registration and configuration
    }
}

Note: Middleware configuration (OnApplicationInitialization) should only be done in the final host application, not in reusable modules.

Dependency Injection Conventions

Automatic Registration

ABP automatically registers services implementing marker interfaces:

ITransientDependency → Transient lifetime
ISingletonDependency → Singleton lifetime
IScopedDependency → Scoped lifetime

Classes inheriting from ApplicationService, DomainService, AbpController are also auto-registered.

Repository Usage

You can use the generic IRepository<TEntity, TKey> for simple CRUD operations. Define custom repository interfaces only when you need custom query methods:

csharp

// Simple CRUD - Generic repository is fine
public class BookAppService : ApplicationService
{
    private readonly IRepository<Book, Guid> _bookRepository; // ✅ OK for simple operations
}

// Custom queries needed - Define custom interface
public interface IBookRepository : IRepository<Book, Guid>
{
    Task<Book> FindByNameAsync(string name); // Custom query
}

public class BookAppService : ApplicationService
{
    private readonly IBookRepository _bookRepository; // ✅ Use custom when needed
}

Exposing Services

csharp

[ExposeServices(typeof(IMyService))]
public class MyService : IMyService, ITransientDependency { }

Important Base Classes

Base Class	Purpose
`Entity<TKey>`	Basic entity with ID
`AggregateRoot<TKey>`	DDD aggregate root
`DomainService`	Domain business logic
`ApplicationService`	Use case orchestration
`AbpController`	REST API controller

ABP base classes already inject commonly used services as properties. Before injecting a service, check if it's already available:

Property	Available In	Description
`GuidGenerator`	All base classes	Generate GUIDs
`Clock`	All base classes	Current time (use instead of `DateTime`)
`CurrentUser`	All base classes	Authenticated user info
`CurrentTenant`	All base classes	Multi-tenancy context
`L` (StringLocalizer)	`ApplicationService`, `AbpController`	Localization
`AuthorizationService`	`ApplicationService`, `AbpController`	Permission checks
`FeatureChecker`	`ApplicationService`, `AbpController`	Feature availability
`DataFilter`	All base classes	Data filtering (soft-delete, tenant)
`UnitOfWorkManager`	`ApplicationService`, `DomainService`	Unit of work management
`LoggerFactory`	All base classes	Create loggers
`Logger`	All base classes	Logging (auto-created)
`LazyServiceProvider`	All base classes	Lazy service resolution

Useful methods from base classes:

CheckPolicyAsync() - Check permission and throw if not granted
IsGrantedAsync() - Check permission without throwing

Async Best Practices

Use async all the way - never use .Result or .Wait()
All async methods should end with Async suffix
ABP automatically handles CancellationToken in most cases (e.g., from HttpContext.RequestAborted)
Only pass CancellationToken explicitly when implementing custom cancellation logic

Time Handling

Never use DateTime.Now or DateTime.UtcNow directly. Use ABP's IClock service:

csharp

// In classes inheriting from base classes (ApplicationService, DomainService, etc.)
public class BookAppService : ApplicationService
{
    public void DoSomething()
    {
        var now = Clock.Now; // ✅ Already available as property
    }
}

// In other services - inject IClock
public class MyService : ITransientDependency
{
    private readonly IClock _clock;

    public MyService(IClock clock) => _clock = clock;

    public void DoSomething()
    {
        var now = _clock.Now; // ✅ Correct
        // var now = DateTime.Now; // ❌ Wrong - not testable, ignores timezone settings
    }
}

Tip: Before injecting a service, check if it's already available as a property in your base classes.

Business Exceptions

Use BusinessException for domain rule violations with namespaced error codes:

csharp

throw new BusinessException("MyModule:BookNameAlreadyExists")
    .WithData("Name", bookName);

Configure localization mapping:

csharp

Configure<AbpExceptionLocalizationOptions>(options =>
{
    options.MapCodeNamespace("MyModule", typeof(MyModuleResource));
});

Localization

In base classes (ApplicationService, AbpController, etc.): Use L["Key"] - this is the IStringLocalizer property
In other services: Inject IStringLocalizer<TResource>
Always localize user-facing messages and exceptions

Localization file location: *.Domain.Shared/Localization/{ResourceName}/{lang}.json

json

// Example: MyProject.Domain.Shared/Localization/MyProject/en.json
{
  "culture": "en",
  "texts": {
    "Menu:Home": "Home",
    "Welcome": "Welcome",
    "BookName": "Book Name"
  }
}

❌ Never Use (ABP Anti-Patterns)

Don't Use	Use Instead
Minimal APIs	ABP Controllers or Auto API Controllers
MediatR	Application Services
`DbContext` directly in App Services	`IRepository<T>`
`AddScoped/AddTransient/AddSingleton`	`ITransientDependency`, `ISingletonDependency`
`DateTime.Now`	`IClock` / `Clock.Now`
Custom UnitOfWork	ABP's `IUnitOfWorkManager`
Manual HTTP calls from UI	ABP client proxies (`generate-proxy`)
Hardcoded role checks	Permission-based authorization
Business logic in Controllers	Application Services
