Summary

In the Japanese locale of the Claude Code desktop app, the toolbar button that toggles the diff view (top-right of a session, shortcut ⇧⌘D) shows its tooltip as "ディフ" — a direct katakana transliteration of the English word "diff". To native Japanese speakers this reads as unnatural. The natural term used in Japanese software for this concept is "差分" (or the button could simply keep the English word "Diff" untranslated).

Steps to Reproduce

Open the Claude Code desktop app with the display language set to Japanese
Open any session
Look at the toolbar icons in the top-right corner of the session (next to the terminal and globe icons)
Hover over the square/box icon that toggles the diff view
Observe the tooltip text

Expected Behavior

The tooltip should use a natural Japanese term, e.g. "差分" (or "変更差分"), instead of a katakana transliteration of the English word.

Actual Behavior

The tooltip shows "ディフ ⇧⌘D" (see attached screenshot).

Environment

App: Claude Code desktop app
Claude Code Version: 2.1.218 (Claude Code)
OS: macOS
Language setting: Japanese

Additional Context

This is a minor wording issue rather than a functional bug, but katakana transliterations of common English tech terms are generally avoided in well-localized Japanese software when a natural equivalent already exists (here, "差分").
