## What it is
A Ruby gem that audits Rails ActiveRecord models against the database schema to detect inconsistencies and inefficiencies. It reports missing constraints, validations, indexes, foreign keys, and other schema-model mismatches.

## Use cases
- find missing null constraints between rails models and database schema
- detect missing unique indexes for uniqueness validations
- check foreign keys for belongs_to associations
- find redundant indexes in a rails database
- audit enum values mismatch between database and activerecord
- verify primary key and foreign key type consistency
- catch missing presence validations for non-null columns

## When to choose
- you maintain a Ruby on Rails app with ActiveRecord and want to catch schema/model drift
- you want to enforce database-level constraints matching model validations in CI
- you need to find missing or redundant indexes to improve query performance

## When to avoid
- your project does not use Ruby on Rails or ActiveRecord
- you need a general-purpose database migration or schema design tool rather than a consistency checker
