igmarin/rails-agent-skills

Curated library of 28 public AI agent skills for Ruby on Rails development. Organized by category: testing, code-quality, engines, infrastructure, api, and context. Covers code review, architecture, security, testing (RSpec), engines, Hotwire, and TDD automation. Shared Ruby skills (YARD docs, DDD, service objects) have moved to ruby-core-skills. Repository agents remain documented in GitHub but are intentionally excluded from the Tessl tile.

Example 1 — Move a PORO (pricing calculator)

Task: "Extract the Pricing::Calculator into MyEngine with no host-model dependency yet."

Expected output (JSON):

{ "slice_name": "pricing_calculator", "actions": [ "move app/services/pricing/calculator.rb -> my_engine/app/services/my_engine/pricing_calculator.rb", "rename module Pricing::Calculator -> MyEngine::PricingCalculator", "add minimal spec to spec/services/my_engine/pricing_calculator_spec.rb" ], "verification_commands": [ "bundle exec rspec spec/services/pricing/ spec/requests/orders/" ] }

Example 2 — Add adapter for current_user

Task: "Engine needs current_user; provide a configurable provider seam."

Expected output (JSON):

{ "slice_name": "order_creator_adapter", "actions": [ "add lib/my_engine/configuration.rb with current_user_provider attr_accessor", "change OrderCreator.for_request to use MyEngine.config.current_user_provider.call(request)", "document host initializer and expected callable signature" ], "verification_commands": [ "bundle exec rspec spec/services/order_creator_spec.rb"] }
