## What it is
A Ruby gem that detects database issues in Rails applications, such as extraneous indexes, missing foreign key constraints, and validations not backed by database constraints. It ships as a set of Rake tasks that analyze Active Record models and schemas before problems reach production.

## Use cases
- find missing foreign key constraints in a rails app
- detect unindexed foreign keys before deploying
- check uniqueness validations are backed by unique indexes
- find extraneous indexes slowing down writes
- audit activerecord models against the database schema
- detect missing non-null constraints on columns

## When to choose
- you maintain a Ruby on Rails application with Active Record
- you want automated database schema health checks in CI
- you need to catch index and constraint gaps before production

## When to avoid
- your project does not use Ruby on Rails or Active Record
- you need general-purpose database monitoring rather than schema/model consistency checks

## Facets
- artifact type: library
- maturity: active
- function: database, testing, developer-tools
- domain: databases, developer-tools, web-development
- platform: ruby, cli
- tags: rails, activerecord, database-health, linting, schema-validation
