Basics

This check has a base priority of normal and works with any version of Elixir.

Explanation

Forbids manual alias statements inside Phoenix scope blocks in router files.

scope/2 and scope/3 already prefix every controller and LiveView reference with the scope's alias argument. Layering an explicit alias on top defeats that prefixing, makes route lookup harder for tools, and diverges from the rest of the project's router conventions.

The check fires only on files matching *_router.ex or **/router.ex.

Bad

scope "/admin", MyAppWeb.Admin do
  alias MyAppWeb.Admin.Users
  get "/users", Users.IndexController, :index
end

Good

scope "/admin", MyAppWeb.Admin do
  get "/users", Users.IndexController, :index
end
