A naming guide for files and folders in TypeScript and JavaScript projects. It recommends kebab-case, with documented exceptions for React components and custom hooks.

Use it when creating files or directories, especially modules, React component files, and custom hook files.

It prevents inconsistent names and avoids case-related problems between operating systems such as Windows and macOS.

file-naming — Skill for Claude Code by ncaq

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add ncaq/konoka --skill file-naming

Clone the repo

git clone --depth 1 https://github.com/ncaq/konoka

Made for: Claude Code.

Or install web-tasuke, the plugin that ships this one along with the rest of its 17 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.00720
Opus 5	$0.00013	$0.00360
Sonnet 5	$0.00005	$0.00144
Haiku 4.5	$0.00003	$0.00072

Security

Grade A, and why

file-naming scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ファイル名とディレクトリ名の規約

基本ルール

ディレクトリ名やファイル名はkebab-caseを使います。

src/
  api/
    customer-query.ts

kebab-caseを基本とする理由は以下の通りです。

URLやnpmパッケージ名などweb標準のエコシステムではkebab-caseが一般的です。それに従ってTypeScript/JavaScriptのプロジェクトでもkebab-caseが広く採用されています。

ファイルシステムの大文字小文字の扱いがOS間で異なります。 macOSやWindowsはデフォルトでcase-insensitiveなので、 UserList.tsxとuserList.tsxを区別できません。 kebab-caseならこの問題が発生しません。

Reactコンポーネントファイル

Reactコンポーネントをエクスポートするファイルは、同じ名前のPascalCaseを使っても構いません。

メインの利用目的と一致しているため、対応関係が分かりやすくなります。

React公式もチュートリアルでそのような名前を使うこともあります。

src/
  components/
    SearchDialog.tsx    # SearchDialogコンポーネントをエクスポート
    UserList.tsx        # UserListコンポーネントをエクスポート

しかし全てをkebab-caseに統一するのも問題ありません。

ReactのカスタムHooksファイル

単一のReactのカスタムHooksをexportするファイルは、同じ名前のcamelCaseを使っても構いません。

関数名とファイル名が一致するため、対応関係が分かりやすくなります。

React公式もチュートリアルで使っています。

eslint-plugin-react-hooksはファイル名ではなく関数名のuseプレフィックスでHooksを検出するので、ファイル名は自由ですが、一致させた方がわかりやすいでしょう。

src/
  hooks/
    useAuth.ts          # useAuth関数をエクスポート
    useLocalStorage.ts  # useLocalStorage関数をエクスポート

しかし全てをkebab-caseに統一するのも問題ありません。

通常のTypeScript/JavaScriptモジュール

kebab-caseを使うことを推奨します。

単一のexportのモジュールでも、のちのち複数のexportが発生する可能性が割とあるので、 kebab-caseを使うことを推奨します。

プロジェクト内での一貫性

プロジェクト内で既に採用されている規約がある場合はそちらに従ってください。

プロジェクト内で混在している場合は、新規ファイルでは一貫した命名規則を採用して、既存ファイルは変更のついでに徐々に統一していくのが現実的です。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

file-naming is a skill published in the GitHub repository ncaq/konoka (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 25 tokens to every session and 720 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
