FAQPage Schema

How do I generate a system design document from a PRD?▼

To generate a system design document from a PRD, you can use this automation Skill by providing the path to your PRD file. It converts the requirements into a detailed design overview, module specs, and API contracts.

What is automated module decomposition for system design?▼

Automated module decomposition breaks down a high-level system design into distinct modules for efficient implementation. This Skill processes your input to define specific interfaces and data models for each decomposed component.

Can I review and revise existing system design documents automatically?▼

Yes, you can review and revise existing system design documents automatically. This Skill processes document-based inputs to generate comprehensive review reports, helping identify errors and streamline revisions.

Do I need Python to automate interface definition and design generation?▼

Yes, you need Python installed to automate interface definition and design generation. Python is required to orchestrate the various sub-agents that execute the system design and review tasks.

What is the best way to define API contracts from product requirements?▼

The best way to define API contracts from product requirements is using an automation tool that parses PRDs to extract interface definitions. This Skill generates structured API contracts and data models directly from your input documents.

Can I use interactive input to create a system design without a PRD?▼

Yes, you can use interactive input to create a system design without a PRD. This Skill supports PRD-based, document-based, and interactive input modes to generate design overviews and module specifications.
