Frontend Typescript Rules is an agent skill from shinpr/ai-coding-project-boilerplate. React/TypeScriptの型安全性、コンポーネント設計、状態管理ルールを適用。Reactコンポーネント実装時に使用。
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design. It works with TypeScript and React. The repository describes itself as: Agentic coding TypeScript boilerplate for Claude Code: sub-agent workflows with built-in quality checks and context engineering. The licence is MIT.
Read from SKILL.md and the folder at commit 56913a2. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Frontend Typescript Rules loads about 1.1k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 201 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/frontend-typescript-rules/SKILL.md (or your agent's skills folder).実装向けの frontend 固有 React/TypeScript ルール: しきい値、境界での型安全性、コンポーネント/状態の設計、エラーハンドリング、プロジェクト規約。
プロジェクト規約を適用する前に、TypeScript、bundler/framework、lint・format、path alias、React Compiler、代表的なコンポーネントの設定を確認する。設定またはリポジトリで確立済みのパターンに裏付けられた規約を確認済みとして扱い、限られた例から導いた結論には推測であることを明記する。競合するパターンによって公開される振る舞い、互換性、コンポーネント境界が変わる場合は作業を止め、必要な情報源または判断を具体的に示す。
設計変更を促すシグナル:
信頼できない型または取得できない型はunknownで受け、型ガードで絞り込む。asは、runtime/frameworkの不変条件によって対象の型が保証される場合にのみ使用し、その不変条件を近くのコメントに記録する。既存の生成コードまたはサードパーティの型宣言に含まれるanyは、ラップすべき境界入力であり、アプリケーションの契約へanyを広げる根拠にはならない。
アプリ内部では React の Props/State は型保証されており unknown は不要。外部境界では必ず unknown で受け、使用前に型ガードで絞り込む: API レスポンス、localStorage/sessionStorage、URL パラメータ、パースした JSON。制御コンポーネントのフォーム入力は React 合成イベントを通じて型安全に保たれる。
const raw: unknown = await (await fetch(url)).json()
if (!isUser(raw)) throw new ValidationError('invalid user')
const user = raw // User に絞り込み済みfunction UserCard({ user, onSelect }: UserCardProps)。propsを関数に直接型付けしてProps契約を明示するuseState ではなく discriminated union の action 型を用いた useReducer にする"use client" 境界の内側に隔離する。ブラウザ専用 API(window、localStorage、イベントハンドラ)はクライアントコンポーネント内に留める。サーバーコンポーネントで呼ぶとレンダリングが壊れるためである。クライアントのみの SPA(例: Vite)では N/A であり、サーバーコンポーネントランタイムが無いプロジェクトではスキップするResult 型で値として表現する。throw は想定外/回復不能なケースに限るcode を持つ基底 AppError を継承する(例: ValidationError, ApiError, NotFoundError)AppError を上位へ伝播する。Error Boundary はレンダリング時のエラーを捕捉しフォールバック UI を表示するuseEffect 内のデータ取得は、順序が入れ替わった応答とアンマウント後の状態更新に対してガードする。具体的には、AbortController か mounted フラグで stale な結果を中断・無視するか、キャンセルと重複排除を行うサーバー状態ライブラリ(React Query/SWR)を使う。try-catch だけではこれをカバーできないtype Result<T, E> = { ok: true; value: T } | { ok: false; error: E }
class AppError extends Error {
constructor(message: string, readonly code: string, readonly statusCode = 500) {
super(message); this.name = this.constructor.name
}
}Error Boundary — class component が必要となる唯一の箇所:
class ErrorBoundary extends React.Component<{ children: React.ReactNode; fallback: React.ReactNode }, { hasError: boolean }> {
state = { hasError: false }
static getDerivedStateFromError() { return { hasError: true } }
render() { return this.state.hasError ? this.props.fallback : this.props.children }
}import.meta.env.VITE_*、Next.jsの公開変数はprocess.env.NEXT_PUBLIC_*、CRAはprocess.env.REACT_APP_*。フロントエンドのバンドルには公開設定だけを含め、シークレットはサーバー側の境界内に置くbuild スクリプトでプロジェクトの予算に対して監視する。React.lazy + Suspense でコード分割する。再レンダリングを最小化する状態構造にする。メモ化: React Compiler が有効なときはそれに任せる。手動の React.memo/useMemo/useCallback は、プロファイラの実測または参照同一性の必要性で裏付けられる場合に限る(実測されたボトルネック、またはサードパーティ API や effect 依存に対する安定した参照同一性)PascalCase、変数/関数は camelCase、hook は use 接頭辞、定数は SCREAMING_SNAKE_CASEtsconfig、lint設定、代表的なファイルから確認したaliasとimport順序に従う。src/からの絶対pathは設定済みのaliasが対応している場合にのみ使用する© shinpr, MIT.

React/TypeScriptの型安全性、コンポーネント設計、状態管理ルールを適用。Reactコンポーネント実装時に使用。. Frontend Typescript Rules is an agent skill from shinpr/ai-coding-project-boilerplate.
Frontend Typescript Rules fits situations like: frontend & Design work in your project.
Run `npx skills add shinpr/ai-coding-project-boilerplate --skill frontend-typescript-rules -a claude-code`. Or copy the skill folder (.claude/skills-ja/frontend-typescript-rules in shinpr/ai-coding-project-boilerplate) into .claude/skills/frontend-typescript-rules in your project. Claude Code loads it when a task matches its description.
Run `npx skills add shinpr/ai-coding-project-boilerplate --skill frontend-typescript-rules -a codex`. Or copy the skill folder (.claude/skills-ja/frontend-typescript-rules in shinpr/ai-coding-project-boilerplate) into .agents/skills/frontend-typescript-rules in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add shinpr/ai-coding-project-boilerplate --skill frontend-typescript-rules -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/frontend-typescript-rules, .gemini/skills/frontend-typescript-rules, .github/skills/frontend-typescript-rules and .opencode/skills/frontend-typescript-rules in your project.
SKILL.md names no scripts, command-line tools or credentials: Frontend Typescript Rules is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Frontend Typescript Rules is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
