SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill transforms unstructured natural language requirements into precise, formal specifications and constraints, ensuring clarity and testability.

Core Features & Use Cases

  • Requirement Parsing: Extracts structured information from user stories, verbal descriptions, and business rules.
  • Constraint Identification: Detects and categorizes various constraint types (data, business, temporal, etc.).
  • Specification Generation: Outputs formal specifications in BDD, JSON Schema, and structured plain text formats.
  • Use Case: Convert a vague user story like "Users should be able to reset their password easily" into a set of clear, testable requirements and constraints, including password complexity rules and expiration times.

Quick Start

Use the nl-to-constraints skill to convert the following user story into BDD-style specifications: "As a user, I want to be able to log in with my email and password so that I can access my account."

How do I convert natural language requirements into BDD scenarios?

To convert natural language requirements into BDD scenarios, this Skill uses structured parsing and pattern matching to transform informal user stories into formal, testable specifications. It identifies constraints and outputs structured BDD format documentation.

What is the best way to generate JSON schemas from user stories?

Generating JSON schemas from user stories involves extracting structured information and categorizing constraints from informal business rules. This Skill processes verbal descriptions to output formal JSON Schema specifications for automated testing.

Can I extract business constraints from plain text documents?

Yes, you can extract business constraints from plain text documents. The Skill performs requirement parsing on unstructured text to detect and categorize various constraint types like data, business, and temporal rules.

Does this tool work for converting verbal descriptions into formal specifications?

Yes, this tool works for converting verbal descriptions into formal specifications. It addresses the need for precise documentation by transforming unstructured natural language requirements into clear constraints and structured plain text formats.

How do I identify testable constraints from vague product requirements?

To identify testable constraints from vague product requirements, the Skill uses structured parsing to extract information from unstructured text. It categorizes detected constraints to ensure clarity and testability in software engineering documentation.
