## Overview
Rails is the original convention-over-configuration framework: follow its opinions about naming, directories, and REST, and enormous amounts of behavior (routing, ORM, migrations, mailers, jobs, caching) come free. Deviate silently and you fight the framework at every step. This skill covers idiomatic Rails — the parts that make teams fast (ActiveRecord, migrations, Hotwire) and the parts that bite (N+1s, callback spaghetti, deploy config) — plus modern Rails with import maps, Turbo, and Stimulus.
## When to use
- Building a full-stack web app the Rails way (monolith-first).
- Fixing N+1 queries, slow pages, or callback-heavy models.
- Structuring jobs, mailers, and service objects in a growing app.
- Using Hotwire (Turbo + Stimulus) instead of a JS SPA.
- Deploying Rails to production (assets, DB, workers, caching).
- Upgrading Rails across major versions.
- Adding an API to an existing Rails monolith.
