What's Wrong?

When the app language is set to French (fr-FR) in settings, the plugin/skill category names in the plugins menu remain in English.

Affected category names (all displayed in English instead of French):

• Design
• - Productivity
• - - Marketing
• - - - Engineering
• - - - - Data
• - - - - - Finance
• - - - - - - Operations
• - - - - - - - Product management
• - - - - - - - - Brand voice
• - - - - - - - - - Enterprise search
• - - - - - - - - - - Legal
• - - - - - - - - - - - Sales
• - - - - - - - - - - - - Human resources
• - - - - - - - - - - - - - Customer support
• - - - - - - - - - - - - - - Zoom plugin
• - - - - - - - - - - - - - - - Bio research
• - - - - - - - - - - - - - - - - Pdf viewer

The fr-FR.json translation file (in Claude.app/Contents/Resources/) does not contain translations for these skill/plugin category labels. The native app UI elements are correctly translated, but the plugin category names are not.

Platform: macOS
App version: Claude Desktop (latest)
Language setting: French (fr-FR)

What Should Happen?

All plugin/skill category names should be translated to French when the app language is set to fr-FR. Expected translations:

• Design → Conception
• - Productivity → Productivité
• - - Marketing → Marketing
• - - - Engineering → Ingénierie
• - - - - Data → Données
• - - - - - Finance → Finance
• - - - - - - Operations → Opérations
• - - - - - - - Product management → Gestion de produit
• - - - - - - - - Brand voice → Voix de marque
• - - - - - - - - - Enterprise search → Recherche d'entreprise
• - - - - - - - - - - Legal → Juridique
• - - - - - - - - - - - Sales → Ventes
• - - - - - - - - - - - - Human resources → Ressources humaines
• - - - - - - - - - - - - - Customer support → Support client
• - - - - - - - - - - - - - - Zoom plugin → Plugin Zoom
• - - - - - - - - - - - - - - - Bio research → Recherche bio
• - - - - - - - - - - - - - - - - Pdf viewer → Visionneuse PDF

Additional Information

This is a localization bug in the Claude Desktop app (not Claude Code CLI). The plugin/skill category labels are not part of the fr-FR.json translation file bundled in Claude.app/Contents/Resources/. Only the native app shell UI is translated — the skill/plugin menu categories are missing from the translations entirely.
