What's inside
Made for ruby on Rails developers
6 prompts + 1 skill- PromptRails Performance — N+1 Queries, Strict Loading, Counter Caches and Fragment Caching
Speeds up a slow Rails app — finding N+1 queries, includes versus preload versus eager_load, strict_loading, counter caches, database indexes and query plans, and Russian-doll fragment caching — with measured results.
- PromptRails Background Jobs Reliability — Active Job, Sidekiq or Solid Queue
Makes Rails background jobs reliable — idempotent job design, retries and dead jobs, uniqueness, scheduling, queue priorities, transactions and enqueue timing, and monitoring — for Sidekiq, Solid Queue or another Active Job backend.
- PromptRails Major Version Upgrade Plan With Dual Boot and Deprecation Cleanup
Plans upgrading Rails one major version at a time — Ruby compatibility, gem audit, dual booting, fixing deprecation warnings, load_defaults step by step, autoloading with Zeitwerk, and safe rollout.
- PromptRails Security Review — Strong Parameters, Authorisation, Injection and Credentials
Audits a Rails application — strong parameters, object-level authorisation, SQL fragments in where clauses, unsafe html_safe and raw output, file uploads with Active Storage, CSRF and session settings, credentials handling and static analysis with Brakeman.
- PromptHotwire Feature Implementation — Turbo Frames, Turbo Streams and Stimulus
Builds an interactive Rails feature with Hotwire — choosing Turbo Drive, Frames or Streams, broadcasting updates, small Stimulus controllers, form validation flows, progressive enhancement and system tests — without a separate JavaScript framework.
- PromptRails Testing Strategy — Model, Request and System Tests With Factories and HTTP Stubs
Builds a Rails test suite that is fast and trustworthy — choosing RSpec or Minitest conventions, model, request and system tests, factories or fixtures, stubbing external HTTP, testing jobs and mailers, and parallel CI runs.
- SkillRuby on Rails Engineer Partner
A standing Rails partner: query performance and caching, reliable background jobs, version upgrades, security reviews, Hotwire features and testing — conventional, secure and measured.
