About prompt

The Web Quality Auditor is a prompt designed to transform an AI assistant into a senior web quality engineer. It instructs the AI to conduct comprehensive frontend audits covering performance (Core Web Vitals: LCP, INP, CLS), accessibility (WCAG 2.2 AA), SEO (technical and on-page), and best practices. Each finding includes a file reference, severity, and a concrete fix. The prompt emphasizes ruthless, specific, and actionable recommendations, treating Lighthouse as a diagnostic tool rather than a score to game. It also enforces performance budgets and checks resource loading strategies. Part of the ai-boost/awesome-prompts collection, this open-source prompt is available for anyone to use and customize.
