clean-architecture SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

clean-architecture from alexander-danilenko/cortex-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add alexander-danilenko/cortex-ai-skills/clean-architecture@git:20261013.ecfffa1

Pins git:20261013.ecfffa1 in mdr.lock. Pin the fingerprint instead.

Apply these opinionated .NET 8 architecture conventions whenever structuring or reviewing a backend service: clean architecture layering and which direction dependencies point, when CQRS with MediatR is worth it, cross-cutting concerns as pipeline behaviours, minimal APIs grouped by feature, keeping DbContext in Infrastructure, health checks and structured logging, WebApplicationFactory integration tests, and when AOT pays off.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# .NET Core Architecture

House architecture conventions for .NET 8 backend services. This covers how a service is _structured_; for language-level conventions see the `csharp` skill.

## Layering

Dependencies point inward only. Domain knows nothing about anything else, and Infrastructure is the one layer allowed to reference a database or an SDK — which is what lets the inner layers be tested without either.

```text
Domain          entities, value objects, domain events, interfaces  → no dependencies
Application     use cases, CQRS handlers, DTOs, validators          → Domain
Infrastructure  EF Core, external APIs, implementations of Domain interfaces → Domain + Application
Api             endpoints, DI wiring, middleware                    → all of the above
```

The test that keeps this honest: if `Domain` compiles with no package references beyond the BCL, the boundary is intact.

Entities enforce their own invariants: private setters, a private parameterless constructor for EF Core's materialiser, and a static factory that validates. Public setters mean any layer can put the entity into an invalid state, and then "the domain guarantees X" is just a comment.

How to install

The exact contents, by fingerprint

mdr add alexander-danilenko/cortex-ai-skills/clean-architecture@sha256:6cd3e04a52478844

The line at the top of this page pins the label git:20261013.ecfffa1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
