SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill bridges the gap between high-level ideas and concrete, implementable software specifications, ensuring clarity and reducing ambiguity in the development process.

Core Features & Use Cases

  • Specification Generation: Converts plans, feature descriptions, or user requests into structured, detailed specifications.
  • Requirement Definition: Automatically generates user stories, functional requirements, and acceptance criteria.
  • Use Case: You have a rough idea for a new feature. Use this Skill to turn that idea into a formal specification document that developers can use to build the feature accurately.

Quick Start

Use the spec-writer skill to create a specification for the feature described in the attached document 'new-feature-plan.md'.

FAQPage Schema
How do I generate software specifications from unstructured feature plans?

To generate software specifications from unstructured feature plans, you input your rough feature descriptions or plans. The system then transforms these ideas into comprehensive, implementable specifications following the Spec-Driven Development methodology, producing structured user stories and functional requirements.

What is spec-driven development and how does it handle requirement definition?

Spec-driven development is a methodology that bridges high-level ideas and concrete software specifications. It handles requirement definition by automatically generating structured user stories, functional requirements, and acceptance criteria from unstructured plans, ensuring all outputs are testable and technology-agnostic.

Can I create technology-agnostic acceptance criteria for my user stories?

Yes, you can create technology-agnostic acceptance criteria for your user stories. The specification generation process ensures that all derived functional requirements and acceptance criteria remain completely testable and independent of specific underlying technologies or frameworks.

How do I turn a rough feature idea into testable user stories?

You turn a rough feature idea into testable user stories by processing your unstructured feature descriptions through the specification transformation. This automatically extracts and generates structured user stories and functional requirements, ensuring clarity and reducing ambiguity for developers.

What is the best way to write functional requirements for a new feature?

The best way to write functional requirements for a new feature is using spec-driven development to transform high-level ideas into formal specification documents. This approach converts unstructured plans into detailed, testable functional requirements and acceptance criteria, reducing development ambiguity.

Do I need a specific framework to generate specification documents?

No, you do not need a specific framework to generate specification documents. The generated specifications are explicitly designed to be technology-agnostic, meaning the resulting user stories and acceptance criteria can be implemented by developers using any technology stack.
