package-layer

What problem does it solve?

This Skill enforces best practices for shared Go packages (pkg/), ensuring they are reusable, maintainable, and adhere to strict interface design, error handling, and security standards.

Core Features & Use Cases

• Interface Design Validation: Verifies that all services are defined as interfaces.
• Constructor Pattern Enforcement: Ensures New() functions return interface types.
• Error Handling & Context Propagation: Checks for consistent error wrapping and context usage.
• Security Audits: Detects hardcoded secrets and direct environment variable access.
• Use Case: When developing a new microservice, this skill automatically audits the pkg/ directory to guarantee that shared components like HTTP clients, queue producers, or utility functions are implemented according to the project's established clean architecture principles.

Quick Start

Run the package-layer skill to audit the shared packages in the current project.
