Does this skill support frontend testing?

Yes, it includes system specs using Capybara to test user flows and frontend interactions within a Rails environment.

How does it handle code quality?

In the verification step, it automatically runs Rubocop for linting and style consistency, and Brakeman for security vulnerability scanning.

What is Spec Driven Development (SDD)?

SDD is a development methodology where you define requirements through specifications (specs) first, ensure they fail, and then write the minimal amount of code necessary to make them pass.

Which testing frameworks does it use?

This skill is specifically configured for RSpec, the most popular testing framework for Ruby on Rails.

Can I use it with existing issues from GitHub?

Yes, the skill can take a GitHub issue number as an argument and will automatically fetch the issue details to inform the implementation process.

Security & Testing

Guides feature development through a strict Spec Driven Development (SDD) workflow to ensure high test coverage and code quality.

The SDD Feature Implementer is a specialized skill designed to enforce a disciplined development cycle within Ruby on Rails environments. By following the Spec Driven Development (SDD) methodology, it prevents 'code-first' shortcuts by requiring the exploration of existing patterns and the creation of failing RSpec tests before any implementation logic is written. This skill automates the transition between codebase analysis, test writing, minimal implementation, and final verification using industry-standard tools like Rubocop and Brakeman, making it an essential companion for building robust, secure, and well-tested applications.
