Lists multiple specific concrete actions and contexts: 'changes UI, layout, theme, dialogs, sidebars, empty states, settings, prompt input, or other visual UX'. Also specifies concrete implementation constraints like using shadcn components and radix-vega preset.

Clearly answers both 'what' (apply Stave's desktop-first design system for UI/layout/theme changes) and 'when' (explicit 'Use for prompts like...' clause with specific trigger terms and situational triggers like introducing new interface patterns).

Excellent coverage of natural trigger terms including both English and Korean: '디자인', 'UI', 'redesign', 'polish', 'sidebar', 'dialog', 'settings'. Also mentions broader triggers like 'whenever a new interface pattern is introduced'.

Highly distinctive — scoped to a specific repo's design system ('Stave's desktop-first design system'), specific tooling (shadcn, radix-vega preset), and specific UI domains. Unlikely to conflict with other skills due to the narrow, well-defined niche.

The skill is fairly well-organized and most content is project-specific, but there's some redundancy — the 'Do/Don't' section largely restates rules already covered in earlier sections (e.g., the component-first rule is repeated in multiple places). The 'Mission' paragraph includes some generic design philosophy that Claude already understands. Could be tightened by ~20-30%.

Highly actionable: provides a concrete component inventory table, specific decision rules (e.g., 'Need a boolean toggle? → Use Switch'), an exact CLI command for generating missing components (`bunx --bun shadcn@latest add <component> --yes`), specific file paths to check, and a clear QA checklist. Guidance is specific to this repo's actual setup.

The Implementation Workflow section provides a clear 8-step sequence with validation checkpoints (check both themes, check at multiple widths, update docs). The component-first rule acts as a gate before any UI work begins. The QA Checklist provides explicit verification steps covering themes, keyboard access, barrel exports, and documentation updates.

The skill references external files like `docs/ui/shadcn-preset.md`, `src/globals.css`, and `components.json` for deeper context, which is good. However, the SKILL.md itself is quite long (~180 lines of substantive content) with significant inline detail that could be split into referenced files (e.g., the full component inventory table, the glass/depth guidelines). No bundle files are provided to verify references, but the structure is reasonably organized with clear section headers.
