WebSpark - Technical Summary WebSpark is a modular .NET 9 web application suite comprising three specialized tools: PromptSpark (LLM prompt optimization), RecipeSpark (recipe management), and TriviaSpark (quiz platform), all built with ASP.NET Core MVC and Bootstrap 5. The architecture is notably sophisticated, featuring seven modular areas with comprehensive SEO optimization including dynamic meta tags, JSON-LD structured data, canonical URL management, XML sitemaps, multi-engine verification, and Google Analytics 4 integration with Core Web Vitals tracking—backed by 47 passing SEO tests. The project implements a rigorous spec-driven development workflow through SpecKit commands that enforce quality gates: developers must create specifications, implementation plans, task breakdowns, and crucially, undergo adversarial risk assessment (the /speckit.critic command) before coding begins, with automated detection of showstoppers including ASP.NET anti-patterns, security vulnerabilities, and performance issues. The codebase is primarily C# (47%), HTML (40.4%), and SCSS (7%), maintained with strict branch protection rules and a constitutional governance framework, making it suitable for teams prioritizing risk mitigation and quality assurance in enterprise web development. The project remains actively maintained (14 commits in 90 days) despite minimal current adoption, suggesting it's either in early stages or represents internal tooling that could serve as a reference implementation for production-grade .NET applications.
