How does it ensure every Gherkin scenario is tested?

The skill performs a mandatory coverage check at the start of the process, counting Scenario blocks in the .feature file against test shells and halting if there is a discrepancy.

What are the 'James Refactor' principles it follows?

These principles include rules like zero private methods, method responsibility limits, pure domain layers with no framework imports, and mandatory fluent method chaining for business logic.

What is the main purpose of the gti-impl skill?

GTI-Impl is the implementation engine of the GTI workflow. It reads Gherkin specs and test shells to produce complete test assertions and the production code required to make them pass.

Does it support specific testing frameworks?

It is designed to be flexible but prefers fluent assertion styles (like Jest or Chai) and requires specific naming conventions for helper methods to ensure readability.

セキュリティとテスト

Enforces a closed-loop BDD→TDD workflow by generating fluent test assertions and implementing production code based on Gherkin specifications.

GTI-Impl is a specialized Claude Code skill designed for the third phase of the Gherkin-Test-Implement (GTI) workflow. It automates the transition from test shells to production-ready software by analyzing Gherkin feature files, generating comprehensive fluent assertions, and writing the underlying source code to satisfy those tests. By strictly adhering to 'James Refactor' principles—such as zero private methods and pure domain layers—this skill ensures that your codebase remains clean, modular, and highly maintainable while maintaining 100% coverage of defined behavior scenarios.
