avoid-for from ncaq/konoka is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ncaq/konoka/avoid-for@git:20260604.7ff6c60Pins git:20260604.7ff6c60 in mdr.lock. Pin the fingerprint instead.

Avoid for loops (C-style, for...of, for...in) in TypeScript/JavaScript. Prefer higher-order Array methods like map, filter, find, some, every, reduce. Use when writing or reviewing loops or iteration over arrays, objects, Map, Set, or String.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# `for`文をなるべく避ける `for`文は強力すぎて、 コードの意図が読み取りにくくなります。 構造化プログラミングにおいて`goto`相当の機能を避けるのと同じ理由で、 `for`文もなるべく避けてください。 避ける対象は以下の全てです。 - C言語方式の`for (let i = 0; i < n; i++)` - `for...of` - `for...in` forではありませんが、 同じくループ構文の以下も避けてください。 - `while` - `do...while` ## なぜ避けるのか `for`文は何でもできてしまいます。 - 要素の変換 - 絞り込み - 集計 - 検索 - 副作用の実行 どの操作をしているのかはループ本体を注意深く読まないと分かりません。 `map`や`filter`のような高抽象度の関数は、 名前を見ただけで「変換している」「絞り込んでいる」と意図が伝わります。 `goto`が制御フローを自由にしすぎて構造化プログラミングで避けられたのと同じく、 `for`はデータの流れを自由にしすぎます。 より弱く意図の限定された関数に置き換えることで、 読み手の負担が減ります。 ## Arrayの場合 Arrayのメソッドでやりたいことに対応するものを選びます。 | やりたいこと | `for`の代替 | | -------------------------- | ---------------------------- | | 各要素を変換する | `map` | | 変換して一段平坦化する | `flatMap` | | 条件で絞り込む | `filter` | | 最初の一致を探す | `find` / `findIndex` | | 最後の一致を探す | `findLast` / `findLastIndex` | | 含まれるか調べる | `includes` | | 位置を調べる | `indexOf` / `lastIndexOf` | | 一つでも満たすか調べる | `some` | | すべて満たすか調べる | `every` | …

How to install
mdr add ncaq/konoka/avoid-for@sha256:41b40d9724de2f03The line at the top of this page pins the label git:20260604.7ff6c60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
