rails-conventions

A practical Rails skill for teams that value consistency

Build and review Rails 8 code by matching the codebase you already have, not by forcing generic patterns that don’t fit your app.

What this skill helps with

rails-conventions is for real production work in Rails codebases where consistency matters.

It guides agents to:

• inspect local patterns first (models, controllers, routes, tests, deploy setup)
• keep naming and architecture aligned with existing conventions
• write backend-aware job code (good_job or solid_queue) without assumptions
• catch risks early in security, performance, and test coverage

Coverage

• Rails 8 baseline and compatibility constraints
• Naming, layering, and code organization
• Active Record modeling, PostgreSQL features, and migration discipline
• Controllers, params, and response semantics
• REST/resource-focused routing
• Hotwire/Turbo/Stimulus patterns
• Background jobs (adapter detection + backend-specific guidance)
• Performance and caching strategy
• Security checklist
• Testing strategy (Minitest and Minitest::Mock)
• API and serialization conventions
• Optional 37signals-inspired profile

Validate and package

Run the bundled validation script first:

ruby scripts/validate_skill.rb

You can use agent_skills for standard validation and packaging.

# install CLI
gem install agent_skills

# validate
agent-skills validate ./skills/rails-conventions

# package
agent-skills pack ./skills/rails-conventions

# inspect metadata
agent-skills info ./skills/rails-conventions

Example trigger

Use this skill when a request sounds like:

Implement a new billing webhook endpoint in this Rails app, matching existing conventions and tests.
