Does this skill work with popular Rust crates like sqlx and reqwest?

Yes, it provides specific implementation patterns for sqlx (PostgreSQL) and reqwest (HTTP) that follow the adapter pattern.

How does it handle asynchronous code?

It uses the #[async_trait] pattern by default and ensures all traits are Send + Sync to remain compatible with multi-threaded runtimes like Tokio.

What is the primary benefit of the port-adapter-designer skill?

It automates the creation of architectural boundaries in Rust, allowing you to swap out databases or external APIs without changing your core business logic.

Can I use this for unit testing?

Yes, the skill specializes in generating in-memory adapters that allow you to test your logic in isolation without any external infrastructure.

API Development

Architects decoupled Rust applications by designing clean port traits and infrastructure adapter patterns.

About

The Port & Adapter Designer skill helps Rust developers implement hexagonal architecture by creating clear abstractions between core business logic and external dependencies. It automatically identifies when code is tightly coupled to databases, APIs, or file systems and proactively suggests trait-based 'ports' and implementation 'adapters.' By enforcing domain-driven types, async-first patterns, and robust error mapping, this skill ensures your Rust codebase remains highly testable, maintainable, and adaptable to infrastructure changes.
