## What it is
Reek is a code smell detector for Ruby that examines classes, modules, and methods and reports code smells like uncommunicative names, long methods, and feature envy. It is distributed as a Ruby gem with a CLI, configurable via YAML, and supports editor and CI integrations.

## Use cases
- detect code smells in ruby code
- find uncommunicative variable and method names
- lint ruby project for design issues
- enforce code quality in ruby CI pipeline
- identify long methods and feature envy
- generate a todo list of existing smells before refactoring

## When to choose
- you maintain a Ruby or Rails codebase and want automated design-quality feedback
- you want a configurable smell detector with todo-list support for legacy code
- you need editor or CI integration for Ruby static analysis

## When to avoid
- you need linting for languages other than Ruby
- you only want style/formatting checks rather than design smells (use RuboCop's formatter instead)
- you need type checking or runtime analysis

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, parser, developer-tools
- domain: developer-tools, testing, programming-languages
- platform: ruby, cli, cross-platform
- tags: code-smells, static-analysis, ruby-gem, code-quality, refactoring
