SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps in producing a structural design document for systems before coding, reducing complexity and ensuring clarity in the development process.

Core Features & Use Cases

  • Systematic Design Commitment: Forges a commitment to the shape of a system before coding, with a focus on module boundaries, contracts, and data shapes.
  • Pre-Coding Analysis: Triggered when discussing new features, services, or codebases, to avoid sprawl and ensure a clear development path.
  • Audit and Raising Issues: Identifies under-specification in prompts, asking clarifying questions to ensure a complete design.

Quick Start

Start the design-doc skill by initiating it in the conversation when planning a new feature or system design.

FAQPage Schema
How do I create a system design document before coding to define module boundaries?▼

System design documents clarify module boundaries and contracts before coding, reducing development complexity. This pre-coding analysis prevents sprawl and ensures a clear development path when planning new features or services.

Why does my system architecture sprawl when I start coding without a design document?▼

Your system architecture sprawls without a design document because module boundaries and data contracts remain undefined. Generating a pre-coding structural commitment clarifies the system shape and prevents uncontrolled complexity during implementation.

Can I use this pre-coding system design approach for complex system specifications?▼

Yes, this pre-coding system design approach handles complex system specifications. It audits under-specified prompts by asking clarifying questions, ensuring your architectural design captures complete module contracts and data shapes.

Does the generated design document work with any programming language?▼

Yes, the generated design document works with any programming language because it utilizes language-neutral terminology for system architecture specifications. This ensures compatibility across different tech stacks during your pre-coding analysis.

What is the best way to define data contracts and module boundaries for a new service?▼

The best way to define data contracts and module boundaries is generating a comprehensive design document before implementation. This pre-coding analysis identifies under-specification early and asks clarifying questions to ensure complete system specifications.

When do I need to generate a design document for system architecture?▼

You need to generate a design document for system architecture when discussing new features, services, or codebases. This pre-coding step avoids sprawl and ensures clarity in module boundaries and contracts before development starts.
