design-an-interface

You compare API designs by generating multiple radically different interface approaches for the same module, then evaluating trade-offs in simplicity, flexibility, and implementation depth to select the optimal direction.

Exploring module boundaries involves generating competing interface designs for the same capability and analyzing their trade-offs, revealing how callers should interact with the module before you commit to a specific contract.

Generating multiple interface designs prevents settling on a first API idea by forcing parallel sub-agent ideation, making it easier to choose a module shape that is simple, flexible, and hard for callers to misuse.

Analyzing trade-offs between competing module architectures requires comparing radically different designs by their simplicity, generality, implementation fit, and depth, then synthesizing the strongest ideas into a balanced final direction.

Yes, you can synthesize a final API direction by combining the strongest ideas from multiple competing interface designs, balancing simplicity, flexibility, and implementation depth into a cohesive module shape.

Parallel sub-agent ideation for interface design is needed when defining an API, revisiting a module boundary, or deciding how callers interact with a new capability, allowing you to compare competing shapes before committing.
