Use bracket or with-style functions to guarantee resource cleanup even on exceptions instead of separate do blocks. Use when writing or reviewing Haskell code that acquires and releases resources.

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.

bracketを使うと、
例外が発生した場合でもリソースの解放を確実に行えます。
bracketでリソースの解放処理が書ける時はそちらを使ってください。
わざわざバラバラのdoブロックで書かないでください。
ライブラリにはbracket関数の特化型である関数がしばしば存在します。
例えば、
withAsync :: MonadUnliftIO m => m a -> (Async a -> m b) -> m b
などの関数です。
存在するならばそれを優先します。
