Authoring and configuration guidance for building React/Next.js frontend applications well from the start — component composition, UX/interaction recipes, Vite config, HeroUI setup, and AI-slop detection (see the Reference files table below for the full breakdown). A companion to language-code-review-edho-ferdian (which reviews code after it's written) — use this when DESIGNING or WRITING new frontend code, not when reviewing existing code. Trigger phrases: \"bagaimana cara structure component ini\", \"best practice React untuk X\", \"setup Vite untuk Y\", \"biar UI-nya gak keliatan AI banget\", \"kok hasil desainnya generic/template banget\", or when starting a new frontend feature.

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
