JavaFX UI/UX design skill — visual design, layout composition, color tokens, typography, spacing systems, CSS styling, control theming, accessibility, and usability improvements for the Renamer App. Use whenever the task involves styling, beautifying, or improving visual appearance — choosing colors, fonts, layouts, spacing, CSS stylesheets, control variants, responsive sizing, dark/light themes, or any UI/UX polish. Trigger on phrases like "make it look better", "improve the UI", "redesign the layout", "style the controls", "create a theme", "CSS for JavaFX", or any visual/aesthetic concern. Complements the separate /javafx skill that handles technical/functional concerns (threading, DI, FXML loading). When both design and functional changes are needed, use this skill for design aspects and /javafx for wiring concerns.
Use when you need to apply Java exception handling best practices — including using specific exception types, managing resources with try-with-resources, securing exception messages, preserving error context via exception chaining, validating inputs early with fail-fast principles, handling thread interruption correctly, documenting exceptions with @throws, enforcing logging policy, translating exceptions at API boundaries, managing retries and idempotency, enforcing timeouts, attaching suppressed exceptions, and propagating failures in async/reactive code. This should trigger for requests such as Exception handling; Use try-with-resources in Java code; Create exception chaining in Java code; Apply fail-fast validation in Java code.
