Does this skill support Behavior-Driven Development (BDD)?

Yes, it is highly proficient in Gherkin syntax, helping you write Given-When-Then scenarios that can be used directly for BDD workflows and automated testing.

Can it help with API documentation?

Absolutely. It includes structured templates for API specifications, covering endpoints, request/response bodies, validation rules, and business logic.

What is the INVEST criteria used by this skill?

It follows the Independent, Negotiable, Valuable, Estimable, Small, and Testable (INVEST) framework to ensure that every user story generated is of high quality and ready for development.

What is the Spec Kit Expert skill?

Spec Kit Expert is a specialized capability for Claude Code that provides expert guidance and templates for writing technical requirements, user stories, and specifications.

How does it improve requirement precision?

The skill utilizes RFC 2119 standard keywords like MUST, SHALL, and SHOULD NOT to ensure that requirement levels are clear and non-ambiguous for engineering teams.
