SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Produces multiple, radically different interface designs and compares them so teams can choose clear, well-scoped API or module shapes without implementing each option first. It reduces decision paralysis by forcing diverse trade-offs and surfacing the simplest, most robust design for the primary use case.

Core Features & Use Cases

  • Parallel design generation: Spawns 3+ sub-agents with distinct constraints to produce diverse interface shapes.
  • Structured outputs: Each design includes interface signatures, usage examples, hidden internals, and trade-offs.
  • Design comparison & synthesis: Compares options on simplicity, depth, efficiency, and correctness, then synthesizes a recommended design.
  • Use Case: Ideal when designing APIs, libraries, or modules and when exploring "design it twice" alternatives to prevent premature commitment.

Quick Start

Run the command /design-an-interface payment-processor to generate three radically different interface designs and a final recommendation.

FAQPage Schema
How do I compare different API design options before writing code?

To compare different API design options before implementation, you can generate multiple radically different interface designs with distinct constraints, then evaluate them on simplicity, depth, efficiency, and correctness to choose the most robust shape.

What is the design it twice approach for library and module architecture?

The design it twice approach for library and module architecture involves generating multiple diverse interface shapes with different constraints, analyzing their trade-offs, and synthesizing a recommendation to prevent premature commitment to a single design.

How do I generate alternative interface signatures and usage examples for abstraction scenarios?

You can generate alternative interface signatures and usage examples by spawning parallel sub-agents with distinct constraints, which produce diverse interface shapes, hidden internals, and trade-off analyses for your abstraction scenarios.

Does this interface design method work for evaluating module and API correctness without full implementation?

Yes, this method works for evaluating module and API correctness without full implementation by comparing generated interface designs on simplicity, depth, efficiency, and correctness, then synthesizing a final recommended design.

What is the best way to eliminate decision paralysis when choosing an API shape?

The best way to eliminate decision paralysis when choosing an API shape is to force diverse trade-offs by generating multiple radically different interface designs, comparing them structurally, and synthesizing a clear recommendation for the primary use case.
