DESCRIPTION = 
<<~DESC.strip
  Returns schema context for ActiveRecord models: columns with types, indexes,
  associations, and foreign keys missing an index. Use the models param to scope
  to specific models; omit it to get all models. Use this to understand your data
  model structure and spot missing indexes that could be causing slow queries or
  N+1 patterns.
