At a glance

ABP project layer dependency rules - which projects can reference which, domain/application/infrastructure separation, cross-layer violations to avoid.

  • Works in 4 steps: Domain logic never depends on… → Use abstractions (interfaces) for… → Higher layers depend on lower layers,… → …
  • Reviewing project structure
  • SKILL.md covers Core Principles (All Templates), Layered Template Structure, Critical Rules and Repository Pattern Enforcement, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Abp Dependency Rules is an agent skill from abpframework/abp. ABP project layer dependency rules - which projects can reference which, domain/application/infrastructure separation, cross-layer violations to avoid. Use when reviewing project structure, adding new project references, or checking if a dependency direction is correct.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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.

When your agent uses it

  • Reviewing project structure
  • Adding new project references
  • Checking if a dependency direction is correct

Example prompts

  • “/abp-dependency-rules”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Domain logic never depends on infrastructure (no DbContext in domain/application)
  2. Use abstractions (interfaces) for dependencies
  3. Higher layers depend on lower layers, never the reverse
  4. Data access through repositories, not direct DbContext

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).

    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

Abp Dependency Rules loads about 1.2k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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 project layer dependency rules - which projects can reference which, domain/application/infrastructure separation, cross-layer violations to avoid. Use when reviewing project structure, adding new project references, or checking if a dependency direction is correct.

ABP Dependency Rules

Core Principles (All Templates)

These principles apply regardless of solution structure:

  1. Domain logic never depends on infrastructure (no DbContext in domain/application)
  2. Use abstractions (interfaces) for dependencies
  3. Higher layers depend on lower layers, never the reverse
  4. Data access through repositories, not direct DbContext

Layered Template Structure

Note: This section applies to layered templates (app, module). Single-layer and microservice templates have different structures.

Domain.Shared    → Constants, enums, localization keys
       ↑
    Domain       → Entities, repository interfaces, domain services
       ↑
Application.Contracts → App service interfaces, DTOs
       ↑
  Application    → App service implementations
       ↑
   HttpApi       → REST controllers (optional)
       ↑
     Host        → Final application with DI and middleware
Layered Dependency Direction
ProjectCan ReferenceReferenced By
Domain.SharedNothingAll
DomainDomain.SharedApplication, Data layer
Application.ContractsDomain.SharedApplication, HttpApi, Clients
ApplicationDomain, ContractsHost
EntityFrameworkCore/MongoDBDomainHost only
HttpApiContracts onlyHost

Critical Rules

❌ Never Do
csharp
// Application layer accessing DbContext directly
public class BookAppService : ApplicationService
{
    private readonly MyDbContext _dbContext; // ❌ WRONG
}

// Domain depending on application layer
public class BookManager : DomainService
{
    private readonly IBookAppService _appService; // ❌ WRONG
}

// HttpApi depending on Application implementation
public class BookController : AbpController
{
    private readonly BookAppService _bookAppService; // ❌ WRONG - Use interface
}
✅ Always Do
csharp
// Application layer using repository abstraction
public class BookAppService : ApplicationService
{
    private readonly IBookRepository _bookRepository; // ✅ CORRECT
}

// Domain service using domain abstractions
public class BookManager : DomainService
{
    private readonly IBookRepository _bookRepository; // ✅ CORRECT
}

// HttpApi depending on contracts only
public class BookController : AbpController
{
    private readonly IBookAppService _bookAppService; // ✅ CORRECT
}

Repository Pattern Enforcement

Interface Location
csharp
// In Domain project
public interface IBookRepository : IRepository<Book, Guid>
{
    Task<Book> FindByNameAsync(string name);
}
Implementation Location
csharp
// In EntityFrameworkCore project
public class BookRepository : EfCoreRepository<MyDbContext, Book, Guid>, IBookRepository
{
    // Implementation
}

// In MongoDB project
public class BookRepository : MongoDbRepository<MyDbContext, Book, Guid>, IBookRepository
{
    // Implementation
}

Multi-Application Scenarios

When you have multiple applications (e.g., Admin + Public API):

Vertical Separation
MyProject.Admin.Application      - Admin-specific services
MyProject.Public.Application     - Public-specific services
MyProject.Domain                 - Shared domain (both reference this)
Rules
  • Admin and Public application layers MUST NOT reference each other
  • Share domain logic, not application logic
  • Each vertical can have its own DTOs even if similar

Enforcement Checklist (Layered Templates)

When adding a new feature:

  1. Entity changes? → Domain project
  2. Constants/enums? → Domain.Shared project
  3. Repository interface? → Domain project (only if custom queries needed)
  4. Repository implementation? → EntityFrameworkCore/MongoDB project
  5. DTOs and service interface? → Application.Contracts project
  6. Service implementation? → Application project
  7. API endpoint? → HttpApi project (if not using auto API controllers)
