AI Coding Skills for Ruby
Browse the best AI coding skills for Ruby in 2026, Rails 8 scaffolding, RSpec / Minitest patterns, Sorbet typing, ActiveRecord schemas, Sidekiq jobs, and Stripe payments. Works with every major AI coding tool.
Short answer
The best AI coding skills for Ruby are skills-hub's `code-review`, `unit-test` (RSpec + Minitest), `api-scaffold` (Rails 8 with Solid stack), `db-schema` (ActiveRecord), `secure` (Brakeman + bundler-audit), and `stripe` integration. All portable across Claude Code, Cursor, Codex CLI, Copilot, and Cline.
Ruby in 2026 means Rails 8 with the Solid stack (Solid Queue, Solid Cache, Solid Cable replacing Redis dependencies), and AI tooling has matured around it. The skills below detect your Ruby stack (Rails 8+, RSpec, Minitest, Sidekiq, Sorbet typing where present, Hotwire / Turbo) and emit idiomatic Ruby, proper service objects, well-typed if Sorbet is present, ActiveRecord that doesn't hit N+1 cliffs.

01linter
1 installsConfigure linting, formatting, and editor integration for any stack. Sets up ESLint 9 or Biome for JS/TS, Ruff for Python, golangci-lint for Go, Clippy for Rust, RuboCop for Ruby, or dart analyze for Flutter. Adds Prettier or equivalent formatter, .editorconfig, and VS Code format-on-save. Use when you need to add a linter, fix formatting inconsistencies, migrate from legacy lint tools, or set up code style enforcement.

Frequently asked questions
Does AI handle Rails 8 conventions?
Yes, modern skills know the Solid stack defaults (Solid Queue instead of Sidekiq for new apps, Solid Cache instead of Redis), Hotwire-first frontend, and the new default deployment target via Kamal 2.
Can AI write Sorbet-typed Ruby?
Yes. If the project has sorbet/config and sigs, the code-review and unit-test skills emit T::Sig signatures and respect the existing typing strictness.
What's the best AI tool for Rails?
Cursor and Claude Code are both strong. Cursor's solargraph + ruby-lsp combo gives the best inline experience; Claude Code excels at multi-model Rails refactors (e.g., extracting service objects).
Do AI skills handle Sidekiq vs Solid Queue?
Yes, modern skills detect which queue backend is configured and scaffold jobs in the right style (Sidekiq::Worker classes vs ApplicationJob subclasses).
