hexagonal-architecture SKILL.md skillA

hexagonal-architecture from hashgraph-online/awesome-codex-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add hashgraph-online/awesome-codex-plugins/hexagonal-architecture@git:20260512.6523792

Pins git:20260512.6523792 in mdr.lock. Pin the fingerprint instead.

Design, implement, and refactor Ports & Adapters systems with clear domain boundaries, dependency inversion, and testable use-case orchestration across TypeScript, Java, Kotlin, and Go services.

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

# Hexagonal Architecture

Hexagonal architecture (Ports and Adapters) keeps business logic independent from frameworks, transport, and persistence details. The core app depends on abstract ports, and adapters implement those ports at the edges.

## When to Use

- Building new features where long-term maintainability and testability matter.
- Refactoring layered or framework-heavy code where domain logic is mixed with I/O concerns.
- Supporting multiple interfaces for the same use case (HTTP, CLI, queue workers, cron jobs).
- Replacing infrastructure (database, external APIs, message bus) without rewriting business rules.

Use this skill when the request involves boundaries, domain-centric design, refactoring tightly coupled services, or decoupling application logic from specific libraries.

## Core Concepts

- **Domain model**: Business rules and entities/value objects. No framework imports.
- **Use cases (application layer)**: Orchestrate domain behavior and workflow steps.
- **Inbound ports**: Contracts describing what the application can do (commands/queries/use-case interfaces).

How to install

The exact contents, by fingerprint

mdr add hashgraph-online/awesome-codex-plugins/hexagonal-architecture@sha256:aebd20d983a894af

The line at the top of this page pins the label git:20260512.6523792, 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.
