## What it is
csscss is a Ruby command-line tool that parses CSS files and reports which rulesets share duplicated declarations. It also supports Sass/SCSS and LESS files and can analyze remote CSS via URL.

## Use cases
- find duplicate declarations in css files
- reduce css redundancy in a stylesheet
- analyze scss files for duplicated rules
- lint css for repeated styles
- compare css rulesets for shared declarations

## When to choose
- you maintain a large CSS codebase and want to cut duplication
- you use Sass or LESS and want redundancy analysis on preprocessed styles
- you want a simple CLI report rather than automatic refactoring

## When to avoid
- you want a tool that automatically removes or refactors duplicated CSS
- you need actively maintained tooling - the last release was in 2018
- you need integration with modern build pipelines beyond legacy grunt/gulp plugins

## Facets
- artifact type: cli-tool

- function: parser, linter, developer-tools
- domain: web-development, frontend, developer-tools
