About this skill

フロントエンド実装スキル

github/awesome-copilotweb-coder を参考にした、Webフロントエンド実装向けの軽量スキルです。

  • 既存の構成、命名、スタイル方針を先に確認する
  • React + TypeScriptでは型安全にし、不要な any や大きな抽象化を避ける
  • CSSはモバイルファーストで、はみ出し、折り返し、タップしやすさを優先する
  • UIは意味のあるHTML、ラベル、フォーカス状態、十分なコントラストを保つ
  • アニメーションや装飾は、デモの理解を助ける最小限にする
  • 変更後は npm run build と主要画面のブラウザ確認を行う

When not to use it

  • When avoiding type-safe code or large abstractions

Prerequisites

npm

Limitations

  • Requires existing style and naming conventions to be checked first

How it compares

This approach enforces specific frontend quality standards like mobile-first CSS and accessibility patterns during the coding process instead of as a post-development step.
