How does the INVEST scoring work?

The skill analyzes generated requirements to ensure they are Independent, Negotiable, Valuable, Estimable, Small, and Testable, providing a score to reflect quality.

What is the EARS format used in this skill?

EARS (Easy Approach to Requirements Syntax) is a structured language template that helps authors write requirements that are clear, concise, and easy to test.

Can I provide a file as a requirement source?

Yes, the specify skill can accept either a direct text description or a file path to an existing requirements document.

Where are my specifications saved?

All generated content is stored in a dedicated .specs/ directory in your project root, organized by feature name for easy navigation.

Productivity & Workflow

Generates professional, canonical specifications from feature requests and user stories using the EARS framework.

The specify skill automates the first phase of the Spec-Driven Development (SDD) workflow by transforming informal feature requests or requirements into structured, validated specifications. It utilizes the Easy Approach to Requirements Syntax (EARS) for clarity and evaluates requirements against INVEST criteria to ensure they are high quality and ready for implementation. By creating a standardized .specs/ directory, this skill provides a single source of truth that includes problem statements, scope boundaries, non-functional requirements, and acceptance criteria, laying a robust foundation for subsequent design and task breakdown phases.
