efcore-abstractions

efcore-abstractions is a skill for Claude Code, Codex from baoduy/drunk-mcp-proxy. It costs 29 tokens per session (3,288 once invoked), scanned A, original, MIT.

A .NET package foundation for Entity Framework Core, the Microsoft data-access framework. It provides base entities and patterns for audit history, domain events, soft deletion, and handling concurrent updates.

In plain words
What is it for?
Use it when defining domain entities, tracking who changed records, raising domain events, hiding deleted records, and preventing conflicting updates.
Why use it?
It avoids rebuilding these common database behaviours for every entity and makes them consistent across an application.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

efcore-abstractions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

EF Core Abstractions Skill

This skill helps GitHub Copilot generate code using DKNet's EF Core Abstractions package (DKNet.EfCore.Abstractions) for creating domain entities with audit trails, events, and soft delete support.

🎯 Package Purpose

DKNet.EfCore.Abstractions provides:

  • Base Entity Classes - Generic entity foundations with various key types
  • Audit Interfaces - Automatic tracking of who/when records were created/modified
  • Event Management - Domain event support for entities
  • Soft Delete - Logical deletion without physical removal
  • Concurrency Control - Optimistic concurrency with row versions

NuGet Package: DKNet.EfCore.Abstractions

📦 Installation

dotnet add package DKNet.EfCore.Abstractions

🏗️ Base Entity Types

EntityBase (Simple Guid ID Entity)

using DKNet.EfCore.Abstractions;

/// <summary>
///     Product entity.
/// </summary>
public class Product : EntityBase
{
    /// <summary>
    ///     Initializes a new instance of the <see cref="Product"/> class.
    /// </summary>
    public Product()
    {
        Id = Guid.NewGuid();
    }
    
    public string Name { get; set; } = string.Empty;
    public decimal Price { get; set; }
    public int Stock { get; set; }
    public bool IsActive { get; set; } = true;
}

// Inherits: Guid Id, DateTime CreatedAt, DateTime? UpdatedAt

Entity (Custom Key Type)

using DKNet.EfCore.Abstractions;

/// <summary>
///     Order entity with integer key.
/// </summary>
public class Order : Entity<int>
{
    public Guid CustomerId { get; set; }
    public DateTime OrderDate { get; set; }
    public decimal TotalAmount { get; set; }
    public OrderStatus Status { get; set; }
}

// Inherits: int Id, DateTime CreatedAt, DateTime? UpdatedAt

AuditEntity (With Audit Trail)

using DKNet.EfCore.Abstractions;

/// <summary>
///     Customer entity with full audit trail.
/// </summary>
public class Customer : AuditEntity<Guid>
{
    public Customer()
    {
        Id = Guid.NewGuid();
    }
    
    public string Name { get; set; } = string.Empty;
    public string Email { get; set; } = string.Empty;
    public string Phone { get; set; } = string.Empty;
    public string Address { get; set; } = string.Empty;
}

// Inherits: Guid Id, DateTime CreatedAt, DateTime? UpdatedAt
//           string CreatedBy, string? UpdatedBy

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
