SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the common issue of implementing features based on unclear or incomplete requirements, leading to wasted effort and incorrect implementations. It ensures clarity and alignment before any code is written.

Core Features & Use Cases

  • Requirement Clarification: Guides users on when and how to write specifications for new features.
  • Ambiguity Resolution: Provides a structured approach to asking clarifying questions one at a time.
  • Traceability: Ensures code is directly linked to its specification for maintainability.
  • Use Case: When starting a complex new feature with multiple potential approaches, use this skill to document the exact requirements, inputs, outputs, and edge cases before writing any code, ensuring everyone is aligned on the desired outcome.

Quick Start

Use the specification-first-development skill to define requirements for a new feature.

FAQPage Schema
How do I define clear requirements before coding a new feature?

Defining requirements before coding involves writing unambiguous specifications that clarify inputs, outputs, and edge cases. This structured approach ensures alignment on desired outcomes and prevents wasted effort from incorrect implementations before development begins.

What is the best way to resolve ambiguity in software requirements?

Resolving ambiguity in software requirements is best achieved through a structured, question-driven process. By asking clarifying questions one at a time, you can systematically address uncertainties and ensure complex feature development is fully understood before implementation.

How does a specification-first workflow handle feature development?

A specification-first workflow handles feature development through a 4-phase process: Specify, Research, Implement, and Verify. This ensures natural language clarity and traceability, directly linking the final code back to its original specification for maintainability.

When should I write specifications for software development instead of coding immediately?

You should write specifications before coding immediately when starting a complex new feature with multiple potential approaches. Documenting exact requirements beforehand addresses complexity by clarifying edge cases and uncertainties, ensuring everyone is aligned on the outcome.

Why do I need to document edge cases before implementing code?

Documenting edge cases before implementing code is needed to prevent incorrect implementations and wasted effort. By clarifying these uncertainties in a specification first, you ensure the exact requirements are well-defined and understood before any development starts.

Can I ensure traceability between my code and its original requirements?

Ensuring traceability between code and requirements is possible by following a specification-first workflow. This approach guarantees that implemented code is directly linked to its initial specification, improving maintainability and verifying that outcomes match the defined inputs and outputs.
