How does this skill prevent AI hallucinations?

It employs strict anti-hallucination rules, including a mandatory 1:1 mapping between Acceptance Criteria and artifacts, and explicitly forbids adding any scenarios not present in the source specification.

What is Forward Derivation in software development?

Forward Derivation is a methodology used to generate technical testing artifacts like BDD features or TDD skeletons directly from approved design specifications to ensure implementation alignment.

What are the prerequisites for running a derivation?

The source specification file must be in a 'spec-approved' state to ensure that the AI is deriving tests from finalized and verified requirements.

Does it support different programming languages?

Yes, as part of the Universal Dev Standards, it produces language-agnostic artifacts like Gherkin .feature files and generic test skeletons compatible with various environments.

Can I generate only specific types of test files?

Yes, the skill supports subcommands such as /derive bdd, /derive tdd, or /derive atdd to generate only the specific artifacts required for your current workflow.

セキュリティとテスト

Automates the generation of BDD, TDD, and ATDD artifacts directly from approved software design specifications.

The Forward Derivation skill streamlines the transition from requirements to implementation by programmatically deriving testing frameworks—including BDD scenarios, TDD skeletons, and ATDD tables—from Software Design Documents (SDD). By enforcing a strict 1:1 mapping between Acceptance Criteria (AC) and generated artifacts, it ensures full traceability and eliminates AI hallucinations or invented requirements during the development phase. This skill is essential for teams following Behavior-Driven Development or Test-Driven Development workflows who want to maintain high fidelity between documentation and codebase.
