SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill generates multiple interface designs for APIs, modules, CLI, protocols, and data contracts, ensuring the first design is not the final one.

Core Features & Use Cases

  • Multiple Design Generation: Produce several different interface designs for a given system.
  • Design It Twice Practice: Apply the "Design It Twice" principle to interface design.
  • Use Case: When you need to design an API, module, CLI, protocol, or data contract and want to explore multiple options before implementation.

Quick Start

Use the design-an-interface skill to generate alternative designs for the new API endpoint.

FAQPage Schema
What is the Design It Twice principle for API design?

The Design It Twice principle for API design involves generating multiple alternative interface designs before implementation. This approach ensures the first design is not the final one, allowing you to explore varied options for APIs, modules, and CLIs.

How do I generate multiple interface designs for a new module or CLI?

You can generate multiple interface designs by applying the Design It Twice practice. This process produces several diverse design options for software components like modules, CLIs, and protocols before you begin actual implementation.

Can I use this approach for protocol and data contract design?

Yes, you can use this approach for protocol and data contract design. The method specifically targets the creation of varied interface designs across APIs, modules, CLIs, protocols, and data contracts.

What is the best way to explore alternative API endpoint designs before coding?

The best way to explore alternative API endpoint designs is to generate multiple varied interface options upfront. This ensures you evaluate diverse design choices for your system components before committing to implementation.

Why should I create multiple designs instead of implementing the first API interface?

Creating multiple designs prevents the first interface design from being the final one. Generating varied alternatives for your API, module, or CLI reveals different architectural possibilities, leading to a more robust final implementation.
