What are the INVEST criteria supported by this skill?

INVEST stands for Independent, Negotiable, Valuable, Estimable, Small, and Testable. This skill evaluates your requirements against these six pillars to ensure they are ready for development.

Can I use this for Gherkin or BDD style criteria?

Yes, it includes specific patterns for refining acceptance criteria into Given/When/Then formats, ensuring they are atomic and independently testable.

How does this skill detect ambiguity in my specs?

The skill scans for subjective or vague terms like 'quickly', 'user-friendly', or 'appropriate' and suggests specific, measurable alternatives to make the requirement objective.

How does the quality scoring system work?

It uses a scoring system (0-2) for each INVEST criterion. A score of 10-12 indicates a high-quality requirement, while lower scores trigger specific refinement suggestions.

Learning & Documentation

Validates and improves software requirements using INVEST criteria and MoSCoW prioritization to ensure clear, testable, and high-quality specifications.

This skill empowers developers and product managers to elevate the quality of project requirements by applying industry-standard frameworks like INVEST (Independent, Negotiable, Valuable, Estimable, Small, Testable). It identifies ambiguous language, provides scoring for requirement readiness, and helps refine acceptance criteria into precise Given/When/Then formats. By automating the assessment and refinement process, it ensures that specifications are complete, actionable, and ready for implementation, reducing downstream development friction and preventing scope creep.
