Prefer left-to-right ascending comparisons with less-than operators over greater-than operators, so values read in number-line order. Use when writing or reviewing comparison or range-check expressions.

Generate a commit message from staged changes and let the user review before committing. Use when the user wants to commit changes or create a git commit.
Generate a GitHub pull request title and body from the current branch and let the user review before creation. Use when the user wants to create a pull request.
Investigate any topic by querying multiple external sources (web, official docs, GitHub, MCP servers). Use whenever a question requires information not already in the working context, including library behavior, API specifications, error diagnostics, version comparisons, or general factual lookup.
himari is ncaq's rio-like custom Haskell Prelude. Import it with a single `import Himari`, never `import Himari.Prelude` or other submodules directly. Use when writing or reviewing Haskell code in a project that depends on the himari package.
Prefer the most specific built-in method over general-purpose ones in TypeScript/JavaScript. Use includes over indexOf, some over filter().length, find over filter()[0], flatMap over map().flat(), at(-1) over length-based access, startsWith/endsWith/includes over indexOf on strings, structuredClone over JSON round-trip. Use when writing or reviewing code that searches, tests, transforms arrays, objects, or strings.
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.

比較を書く時は、
x > yの形式よりx < yの形式を優先してください。
<や<=を使い、
左から右に向かって値が大きくなるように書きます。
頭の中の数直線上に数字を左から右へ並べて考えるため、 左の方が大きいと違和感を覚えるからです。
特に範囲チェックでは、 下限と上限を数直線の並び順に書けるため読みやすくなります。
// 好ましい
if (min <= x && x <= max)
// 避ける
if (x >= min && x <= max)
このルールにそこまで執着はしません。
特に理由がなければ<や<=を好むという程度の優先度です。
その時書いている言語で広く普及しているリンターが、 変数を右に書くのをヨーダ記法として拒否する場合などは、 わざわざ逆らわずリンターに従ってください。
