Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Rails Expert ## Core Workflow 1. **Analyze requirements** — Identify models, routes, real-time needs, background jobs 2. **Scaffold resources** — `rails generate model User name:string email:string`, `rails generate controller Users` 3. **Run migrations** — `rails db:migrate` and verify schema with `rails db:schema:dump` - If migration fails: inspect `db/schema.rb` for conflicts, rollback with `rails db:rollback`, fix and retry 4. **Implement** — Write controllers, models, add Hotwire (see Reference Guide below) 5. **Validate** — `bundle exec rspec` must pass; `bundle exec rubocop` for style - If specs fail: check error output, fix failing examples, re-run with `--format documentation` for detail - If N+1 queries surface during review: add `includes`/`eager_load` (see Common Patterns) and re-run specs 6. **Optimize** — Audit for N+1 queries, add missing indexes, add caching ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Hotwire/Turbo | `references/hotwire-turbo.md` | Turbo Frames, Streams, Stimulus controllers | | Active Record | `references/active-record.md` | Models, associations, queries, perfor

How do I install it?

Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
