Cross-language code-quality heuristics -- function size, nesting depth, magic numbers, comment intent, naming -- for reviewing or writing code in any language. Use when reviewing code for maintainability, setting up lint rules, or onboarding conventions. For Go-specific idioms use go-service-idioms, for API contracts use api-design, for Laravel use laravel-patterns, for Vue/Nuxt use vue-nuxt-frontend-patterns -- this skill is the language-agnostic layer underneath those.
