Implement or improve tray, quick popup, global shortcut, single-instance, and restore behavior for the Windows-first Tauri 2 app.
Use this skill for React + TypeScript implementation, refactoring, and review tasks involving components, hooks, props typing, children typing, refs, effects, context, reducers, events, forms, utility functions, async UI state, generic components, type modeling, module/export conventions, and React architecture decisions. Trigger this skill when creating or refactoring React TypeScript code and when choosing the right abstraction boundary for maintainable React applications.
Use this skill for any UI work in numpad — shadcn components, theming, shell layout, feature UI, settings dialogs, inspector panels, or Windows 11-like desktop productivity styling.
Implement or extend optional, review-first AI infrastructure for numpad without compromising deterministic engine authority.
Align docs/ with the real implementation — remove stale claims, add missing details, correct wrong file names, and update contracts.
Refactor and extend the deterministic calculation engine while preserving correctness and explicit domain boundaries.
Audit the numpad repository — implementation state, docs drift, architecture health, and next priorities.
Implement templates, snapshots, and history for the local-first numpad calculation workspace.
