Rails Dev Plugin

Claude Code plugin with specialized agents and skills for Rails development

A Claude Code plugin that provides specialized agents and portable skills covering models, controllers, views, services, jobs, testing, architecture, DevOps, GraphQL, Hotwire, API design, and more.

Agents auto-detect your project's architecture — where business logic lives (native vs extracted) and how it delivers (html vs api) — plus its coding conventions, then generate code that matches your project — not generic Rails.

Quick Start

# In Claude Code
/plugin marketplace add ag0os/rails-dev-plugin
/plugin install rails-dev-plugin@ag0os

Restart Claude Code, then just ask:

You: "Create a User model with authentication"
You: "Refactor this controller — it has too much business logic"
You: "Add background jobs for email delivery"

Claude automatically selects the right agent based on your request.

What It Does

Agents are specialists that handle implementation tasks — one for models, one for controllers, one for testing, etc. They scan your codebase first to match your existing patterns.

Skills are portable knowledge that agents draw from. They also work independently in the main conversation (e.g., asking about refactoring patterns or caching strategies).

Architecture axes adapt recommendations to how your project is built. A project that keeps logic in models and concerns gets different advice than one built on service objects, and a server-rendered app gets different advice than a headless JSON API. Orthogonal facts — test framework, job backend, auth library — are detected separately and matched directly.

Convention detection goes deeper than profiles — agents detect your specific base classes, naming patterns, result types, auth setup, and more before writing code. They also read your CLAUDE.md for intent that overrides detected patterns.

Agents

Agent	Domain
rails-model	ActiveRecord models, migrations, associations
rails-controller	RESTful controllers, routing, params
rails-service	Service objects, business logic
rails-jobs	Background jobs, ActiveJob, Sidekiq
rails-views	ERB templates, partials, ViewComponents
rails-hotwire	Stimulus controllers, Turbo frames/streams
rails-graphql	GraphQL schema, resolvers, mutations
rails-api	REST API, serialization, JWT
rails-test	RSpec, Minitest, system tests
rails-architect	Architecture planning, design decisions
rails-devops	Docker, CI/CD, deployment, monitoring

Team Setup

Add to your project's .claude/settings.json so the plugin auto-installs for all team members:

{
  "plugins": {
    "marketplaces": [
      {
        "name": "rails-dev",
        "source": "ag0os/rails-dev-plugin"
      }
    ],
    "installed": ["rails-dev-plugin@rails-dev"],
    "autoInstall": true
  }
}

Management

/plugin disable rails-dev-plugin@ag0os    # Disable
/plugin enable rails-dev-plugin@ag0os     # Re-enable
/plugin uninstall rails-dev-plugin@ag0os  # Uninstall
