SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing interfaces for APIs, services, hooks, or components is often stuck at the first idea. This Skill generates multiple radically different designs in parallel and surfaces clear trade-offs to compare.

Core Features & Use Cases

  • Parallel exploration: spawn three sub-agents to produce distinct interface designs.
  • Comparative evaluation: side-by-side analysis of trade-offs, constraints, and hidden assumptions.
  • Guided synthesis: synthesize insights to select or blend a final design.
  • Use cases include API design, service contracts, hooks, or component interfaces across backend and frontend stacks.

Quick Start

Describe your module and constraints to trigger three parallel design explorations for interfaces.

FAQPage Schema
How do I generate multiple API designs in parallel to avoid fixating on the first idea?

To generate parallel API designs, describe your module and constraints to trigger three sub-agents that produce distinct interface designs simultaneously. This parallel exploration surfaces clear trade-offs and hidden assumptions, allowing you to compare radically different approaches instead of relying on a single idea.

What is parallel interface design and how does it help with service contracts?

Parallel interface design is the process of generating multiple radically different service contracts or hooks simultaneously. It helps by producing structured side-by-side comparisons of trade-offs and constraints, enabling a guided synthesis to select or blend the best final design for your backend or frontend context.

Can I use this approach for both frontend component interfaces and backend service contracts?

Yes, you can use this approach for both frontend component interfaces and backend service contracts. The process applies to APIs, service contracts, hooks, and component interfaces across backend and frontend stacks, generating distinct designs and comparative evaluations for any of these contexts.

What's the best way to compare trade-offs between different hook or component designs?

The best way to compare trade-offs is through structured side-by-side analysis of distinct designs generated in parallel. This process evaluates constraints and hidden assumptions for each interface, culminating in a guided synthesis that selects or blends insights into a final recommended design.

How do I start a design review for a new module interface?

To start a design review, describe your module and constraints to trigger three parallel design explorations. The generated interfaces undergo comparative evaluation against your criteria, leading to a guided synthesis that recommends a final design.

When should I use multi-agent exploration for interface design instead of a single draft?

You should use multi-agent exploration when you are stuck at the first idea and need to avoid reliance on a single design. It is ideal for generating radically different APIs or component interfaces, evaluating trade-offs, and synthesizing insights for a robust final design.
