Partial Function (Grade A)セキュリティテスト済みデータ-AIスキル for Claude AI。グレードA。ハスカス言語内の部分関数であるhead、fromJust、read、!!を避ける。総関数、Maybe返却バリアント、他の安全な代替手段を優先しましょう。

Is the skill limited to certain Haskell versions or libraries?

The skill focuses on standard functions found in core libraries (Prelude, Data.List, etc.). It recommends alternatives that are available in common libraries, such as `readMaybe` from `Text.Read` and `NonEmpty` from `Data.List.NonEmpty`.

Does using the skill add significant code overhead?

While it may require additional handling for Maybe or Either types, the trade‑off is reduced runtime exceptions. The skill recommends clear patterns (e.g., listToMaybe, fromMaybe, headMay) that keep code readable without excessive boilerplate.

Can the skill be integrated into existing Haskell projects?

Yes, the skill is designed for use with Claude AI and can be invoked during code review or writing sessions to analyze Haskell code, making it suitable for projects that already use Haskell and want to enforce safe coding practices.

How does the Partial Function skill improve Haskell code safety?

It detects and flags common partial functions like head, fromJust, read, and (!!), then suggests safer alternatives such as total functions, Maybe-returning variants, and NonEmpty types, helping prevent runtime crashes and improve error handling.
