Test it
Using "css-development-refactor". A component repeats the same long button utility classes in many files.
Expected outcome:
The skill identifies the repeated pattern, proposes a semantic button class, updates markup, and recommends tests for the new selector.
Using "css-development-refactor". A card layout has light theme styles but no dark mode support.
Expected outcome:
The skill adds matching dark mode variants, documents the semantic class purpose, and asks for visual verification in both themes.
Using "css-development-refactor". A team needs a summary after a CSS cleanup branch.
Expected outcome:
The skill reports created classes, updated files, test coverage, behavior checks, and practical next steps for review.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Clean Up Utility-Heavy Components
Convert repeated utility class strings into reusable semantic classes for easier maintenance.
Add Dark Mode During Refactoring
Extend refactored classes with dark mode variants while preserving the existing light theme.
Prepare Safer Style Migrations
Document changed selectors, add tests, and verify behavior before merging CSS cleanup work.
Try These Prompts
Use this skill to inspect my components and list repeated inline styles or utility class groups that should become semantic CSS classes.
Refactor the repeated button and card utility classes into semantic CSS classes. Reuse existing components.css patterns before creating new classes.
Review the new semantic CSS classes and add dark mode variants for backgrounds, borders, text, hover, and focus states where needed.
Refactor the selected CSS patterns, update markup, add static CSS and rendering tests, then summarize changed files and behavior verification results.
Best Practices
- Start with repeated patterns and preserve one-off utility classes unless extraction improves maintainability.
- Check existing component styles before adding new classes or variants.
- Verify refactored styles with tests and visual review in light and dark modes.
Avoid
- Do not rename classes without updating every affected component and test.
- Do not create semantic classes that only wrap a single unrelated one-off style.
- Do not claim behavior is unchanged without running available tests or reviewing the UI.
