Use when designing, building, or refactoring backend features, APIs, controllers, services, repositories, or database migrations following clean layered domain architecture and TDD principles.
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
# Layered Domain Architecture & Development Guidelines ## Overview This skill provides a standardized, battle-tested framework for building clean, maintainable, and scalable backend applications using **Layered Domain Architecture** and **Test-Driven Development (TDD)**. All code is strictly separated into distinct layers with clear boundaries: transport handling, domain logic, data access, and API serialization. --- ## When to Use - When scaffolding or implementing a new backend feature, API endpoint, or domain module. - When refactoring "fat controllers" or business logic scattered across models and request handlers. - When isolating database access into clean repository abstractions. - When establishing or reviewing TDD test coverage for endpoints and services. - When writing database migrations that require strict reversibility and referential integrity. ### When NOT to Use - For trivial one-off utility scripts or developer CLI scratchpads with no persistence layer. - When the project explicitly enforces a different design paradigm (e.g., pure micro-functions or event sourcing without repositories). --- ## The Layered Architecture Blueprint ``` …

How to install
mdr add abbasjaber/skill-layered-domain-architecture/layered-domain-architecture@sha256:8b318bbae2fc8c8eThe line at the top of this page pins the label git:20261022.bb4a96e, 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.
