Requirements Engineering is a structured skill designed to bridge the gap between abstract project ideas and concrete technical implementation. Using the Easy Approach to Requirements Syntax (EARS), this skill helps developers, product managers, and technical leads translate stakeholder requests into clear, testable, and unambiguous documentation. By focusing on standard linguistic patterns, the skill ensures that system behaviors are defined consistently, minimizing miscommunication between cross-functional teams and reducing development rework.

The skill guides you through a four-stage process: defining user stories using the classic 'As a, I want, so that' format; generating detailed acceptance criteria using EARS event-response patterns; identifying critical edge cases such as boundary conditions, error states, and concurrency conflicts; and validating the requirements against a strict quality checklist. It is particularly effective for teams adopting spec-driven development, ensuring that every feature is thoroughly understood before a single line of code is written.

• Capture requirements using structured EARS syntax: Event-Response, Conditional, State-Based, and Performance patterns.

• Develop clear user stories that focus on user roles, features, and business benefits.

• Systematically identify and document edge cases, including error handling, boundary conditions, and concurrent access scenarios.

• Use a rigorous validation checklist to ensure completeness, clarity, consistency, and testability of specifications.

• Prevent common pitfalls such as vague language, implementation-heavy requirements, and missed error paths.

• Ideal for software engineers, product managers, and systems architects working on complex feature sets.

• Essential for clarifying ambiguous stakeholder requests or documenting system behavior for automated testing frameworks.

• Use this skill at the initiation phase of any new project or feature lifecycle to ensure shared understanding.

• Expected output is a comprehensive, markdown-ready specification that can serve as the foundation for the Design and Task phases in spec-driven development.

• Avoid using this for unstructured brainstorming; it is designed for creating rigorous documentation suitable for technical implementation.
