React AI
summary
Live demo across five frontier models (ChatGPT 5.1, Copilot, Claude, Grok, Gemini) shows raw AI output produces dangerous React patterns: unvalidated hrefs and dangerouslySetInnerHTML usage, missing URL validation, and unsafe event handlers; a single rule set applied as a system prompt fixes outputs to safe patterns using a validateAndSanitizeURL utility, DOMPurify, Zod and trusted types, converting failing samples to secure, idiomatic React 19.2 code and eliminating the one‑third JavaScript‑URL bypass risk.
