port-adapter-designer
Design Rust Port and Adapter Boundaries
External services can leak infrastructure concerns into domain code. This skill helps design Rust traits and adapters that keep dependencies isolated and testable.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "port-adapter-designer" from https://skillstore.io/skills/emillindfors-port-adapter-designer.md and its manifest at https://skillstore.io/api/skills/emillindfors-port-adapter-designer/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "port-adapter-designer". A Rust service calls SQLx queries directly from domain logic.
Expected outcome:
The skill identifies a repository port, a PostgreSQL adapter, an in-memory test adapter, and domain error mapping.
Using "port-adapter-designer". A payment workflow needs Stripe integration without coupling the domain layer to reqwest.
Expected outcome:
The skill proposes a payment gateway port, a Stripe adapter outline, error categories, and test double guidance.
Using "port-adapter-designer". A notification feature must support email now and SMS later.
Expected outcome:
The skill suggests a focused notification port with separate adapters for each provider and shared domain results.
Security Audit
SafeAll static findings were adjudicated as false positives tied to Markdown Rust examples or normal adapter design text. No evidence found of executable commands, live network behavior by the skill, credential exfiltration, obfuscation, or prompt injection. The skill declares only Read and Grep tools.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Decouple Persistence
Move direct SQLx usage behind repository traits and keep domain logic independent from the database.
Plan Hexagonal Architecture
Define ports and adapters before adding external APIs, queues, file stores, or payment services.
Improve Testability
Create in-memory adapters or mocks so application services can be tested without production infrastructure.
Try These Prompts
Find the external dependency in this Rust module and suggest the smallest useful port trait for it.
Design a Rust adapter for this port. Include construction, error mapping, async behavior, and ownership choices.
Suggest in-memory or mock adapters for these ports and explain which behaviors each test should cover.
Review this Rust service and propose a step-by-step refactor to ports and adapters without changing behavior.
Best Practices
- Keep port traits focused on domain actions, not vendor APIs.
- Use domain types and domain errors at every boundary.
- Add test adapters before wiring production infrastructure.
Avoid
- Expose database rows or HTTP response types through domain traits.
- Create large gateway traits that combine unrelated external systems.
- Let adapters return raw infrastructure errors to application services.
