variable-naming

variable-naming is a skill for Claude Code from ncaq/konoka. It costs 38 tokens per session (1,167 once invoked), scanned A, original, Apache-2.0.

A TypeScript and JavaScript naming guide that recommends camelCase for variables and most constants. camelCase joins words with a capital letter, such as userName.

In plain words
What is it for?
Use it when naming or reviewing variables, parameters, and constants in TypeScript or JavaScript.
Why use it?
It removes repeated debate about whether a value should use uppercase names and keeps naming consistent as code changes.

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.

Security

Grade A, and why

variable-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 4d 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.

変数の命名規則 (TypeScript/JavaScript)

TypeScript/JavaScriptのコードにおける変数の命名規則です。

ファイル名やディレクトリ名についてはfile-namingを参照してください。

基本のケース

変数・パラメータには基本的にcamelCaseを使います。

const taxedPrice = itemPrice * (1 + taxRate);
const userName = profile.displayName;

定数でもUPPER_SNAKE_CASEは避けてcamelCaseを使う

再代入されない定数のように見える変数でも、 基本的にはUPPER_SNAKE_CASEではなくcamelCaseを使ってください。

// 良い
const maxRetryCount = 3;
const apiBaseUrl = "https://example.com";
const emailPattern = /^.+@.+$/;

// 避ける
const MAX_RETRY_COUNT = 3;
const API_BASE_URL = "https://example.com";
const EMAIL_PATTERN = /^.+@.+$/;

理由は以下の通りです。

constがデフォルトになった現代のコードでは、 再代入されないことはconstキーワードが既に表現しています。 UPPER_SNAKE_CASEで「再代入されない」ことを重ねて示すのは冗長です。

UPPER_SNAKE_CASEにすべき「真の定数」の判定は手間がかかります。 主要なスタイルガイド(GoogleやAirbnb)もconstを一律にUPPER_SNAKE_CASEにせよとは言っておらず、 「モジュールレベルかつ意味的に深く不変なプリミティブ値」のような狭い条件に限定しています。 newで生成したオブジェクトや関数、RegExpのように内部状態を持つ値は、 constであってもこの基準では「定数ではない」のでcamelCaseが自然です。 この境界はしばしば曖昧で、宣言のたびに判断するコストが高いです。

ハードコードしていた値を後から計算式や引数に変えるリファクタリングをすると、 UPPER_SNAKE_CASEのままでは名前を付け替える必要が出てきます。 最初からcamelCaseで統一しておけばこの付け替えが発生しません。

camelCaseに統一すれば、 個々の変数が「真の定数」かどうかを判断する必要がなくなり、 コードベース全体で一貫した命名になります。

標準ライブラリやWeb APIの大文字定数について

  • Math.PI
  • Number.MAX_SAFE_INTEGER
  • WebSocket.OPEN

のように標準ライブラリやWeb APIにはUPPER_SNAKE_CASE/UPPER_CASEの定数が存在します。

これらは利用する側であって自分で命名するわけではないので、 提供されている名前をそのまま使ってください。 これらの存在は、 自分のコードでUPPER_SNAKE_CASEを使う理由にはなりません。

これらが大文字なのはC言語からJavaやWeb IDLへと受け継がれた歴史的慣習によるもので、 いずれもプリミティブ型の固定値や整数の列挙値という限られた性質のものです。 自分のコードがこの慣習に追従する義務はありません。

ESLintとの関係

@typescript-eslint/naming-conventionルールのデフォルトは、 variableに対してcamelCaseUPPER_CASEの両方を許容します。 したがってcamelCaseで統一してもlintは通ります。

さらにcamelCaseだけに強制したい場合は、 variableセレクタのformat["camelCase"]のみに設定できます。

列挙的な定数値の定義

複数の固定値をまとめて持つ定数オブジェクトや、 文字列ユニオン型の元になる配列を定義する場合は、 キーも値もUPPER_SNAKE_CASEにせず、 camelCaseのオブジェクトにas constを付ける方法を優先します。 詳細はas-const-satisfiesを参照してください。

variable-naming is a skill published in the GitHub repository ncaq/konoka (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 38 tokens to every session and 1,167 once invoked, about $0.0002 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.
