Individual skill
rails
Use when building or maintaining a Ruby on Rails app — models, controllers, views, routes and migrations; ActiveRecord associations, scopes and query performance; Hotwire (Turbo and Stimulus) UI; Active Job or Solid Queue background work; and Rails tests. Covers N+1 queries, migration safety on live tables, and flaky system tests around Turbo Frames. NOT plain Ruby scripts, gems or CLIs with no Rails loaded (that is `ruby`).

# Build Rails the omakase way
Write Rails the way a core-adjacent senior would: fat-enough models, skinny
controllers, zero N+1, strong parameters, migrations that are reversible and safe on a
live table, and tests that exercise the request rather than the implementation. Lean
into the Rails 8 "omakase" defaults instead of fighting them — the framework already
made the boring choices for you.
This is **Rails the framework**: the MVC request cycle, ActiveRecord, Hotwire, Active
Job, the Rails test stack. The moment code stops loading Rails — a plain script, a gem,
an `Enumerable` refactor with no `ActiveRecord` in sight — it is no longer this skill.
That is `ruby` (see `../ruby/SKILL.md`).
