EARS Requirements Notation

About

Streamlines the requirements engineering process by implementing the EARS framework, a formal notation designed to eliminate ambiguity in software specifications. By guiding users through six specific patterns—Ubiquitous, Event-Driven, State-Driven, Optional, Error Handling, and Complex—it ensures every acceptance criterion is verifiable and consistent. This skill is particularly useful during the discovery and design phases of development, helping teams transition from vague user stories to rigorous, testable requirements that use mandatory keywords like "SHALL" and standardized system references to prevent misinterpretation.
