Implement, review, or improve localization and internationalization in iOS/macOS apps — String Catalogs (.xcstrings), LocalizedStringKey, LocalizedStringResource, pluralization, FormatStyle for numbers/dates/measurements, right-to-left layout, Dynamic Type, and locale-aware formatting. Use when adding multi-language support, setting up String Catalogs, handling plural forms, formatting dates/numbers/currencies for different locales, testing localizations, or making UI work correctly in RTL languages like Arabic and Hebrew.
Build lightweight App Clip experiences for instant iOS app access without full installation. Covers target setup, invocation URL handling, experience configuration, size limits, invocation methods (NFC, QR, App Clip Codes, Safari banners, Maps, Messages), NSUserActivity handling, data migration to the full app via shared App Group containers, SKOverlay for full-app promotion, location confirmation with APActivationPayload, lifecycle considerations, and capability limitations. Use when creating App Clips or configuring App Clip invocation and data migration.
Implement, review, or improve widgets, Live Activities, and controls using WidgetKit and ActivityKit. Use when building home screen, Lock Screen, or StandBy widgets with timeline providers; when creating interactive widgets with Button/Toggle and AppIntent actions; when adding Live Activities with Dynamic Island layouts (compact, minimal, expanded); when building Control Center widgets with ControlWidgetButton/ControlWidgetToggle; when configuring widget families, refresh budgets, deep links, push-based reloads, or Liquid Glass rendering; or when setting up widget extensions, App Groups, and entitlements.
Prepare and publish a new release of datafusion-ducklake to crates.io
Write, review, debug, and improve bash/shell scripts for any context: CI/CD pipelines (GitHub Actions, GitLab CI, Bitrise), DevOps automation, macOS/Linux system tasks, file processing, and data transformation. Use this skill whenever the user asks to write a shell script, improve an existing one, debug a bash error, or automate any task via command line — even if they just say "make a script that does X" or paste a broken script without explanation. Also trigger for requests involving cron jobs, entrypoints, deploy scripts, migration scripts, or any .sh file.
