O que configurar antes de deixar a IA programar por você?
Rocketseat
Jun 16, 2026
Desenvolvedores cometem o erro de delegar toda a arquitetura inicial para IAs, resultando em códigos desorganizados e difíceis de manter. Ao definir manualmente o boilerplate e as regras de estilo antes de usar a IA, você garante um código previsível e evita que o modelo degrade a performance devido ao excesso de contexto aleatório.
Key insight: Quanto mais regras, exemplos e estrutura bem definidos na sua codebase, melhor a IA performa, pois ela começa a copiar o seu padrão de excelência em vez de inventar soluções de baixo nível ("slop").

El paso que te falta antes de pedirle código a la IA no son los Spec.md
HolaMundo
Jun 1, 2026
El desarrollo asistido por IA falla cuando se salta de la especificación directamente al código, consumiendo contexto innecesario y generando resultados erráticos. Al integrar wireframes funcionales en React antes de aplicar diseño o lógica compleja, los desarrolladores logran validar la estructura y acelerar el proceso, ahorrando tokens y evitando retrabajos masivos.
Key insight: Los wireframes permiten validar la distribución y experiencia de usuario desde el primer minuto; al construirlos en React, ese mismo código base sirve de cimiento para la implementación final sin desperdiciar trabajo previo.
