1. rails-simplifier

A code simplification skill that refines Ruby on Rails code following 37signals patterns and the One Person Framework philosophy.

Philosophy

The One Person Framework (DHH, December 2021):

"A toolkit so powerful that it allows a single individual to create modern applications upon which they might build a competitive business."

Conceptual Compression (RailsConf 2018):

"Like a video codec that throws away irrelevant details such that you might download the film in real-time."

Vanilla Rails is Plenty (Jorge Manrubia, 37signals):

"If you have the luxury of starting a new Rails app today, go vanilla."

What It Does

Pattern	Simplification
Service objects	Rich model methods + concerns
Custom controller actions	CRUD resources
Boolean state columns	State records (has_one :closure)
Fat controllers	Thin controllers, model methods
Time.now	Time.current
Hardcoded strings	I18n keys
N+1 queries	includes / preload
Date tests without travel_to	Freeze time to fixture

Usage

> Simplify the recent changes to the bookings controller
> Refactor this to vanilla Rails / 37signals patterns
> Review this model against the rails-simplifier standards

2. rails-upgrade-assistant

A unified, intelligent Rails upgrade assistant that helps you upgrade Ruby on Rails applications through any version from 6.0 to 8.1.1. Built on official Rails CHANGELOGs, it analyzes your project with the standard file tools — no external services required.

What It Does

• Analyzes your Rails project automatically by reading its files
• Detects your current version and target version
• Plans single-hop or multi-hop upgrade paths
• Identifies breaking changes specific to YOUR code
• Preserves your custom configurations with warnings
• Generates comprehensive upgrade reports (50+ pages)
• Based on official Rails CHANGELOGs from GitHub

Supported Upgrade Paths

From	To	Breaking Changes	Difficulty
8.0.x	8.1.1	8 changes	Easy
7.2.x	8.0.4	13 changes	Hard
7.1.x	7.2.3	38 changes	Medium
7.0.x	7.1.6	12 changes	Medium
6.1.x	7.0.0	17 changes	Hard
6.0.x	6.1.0	18 changes	Medium
6.0.x	8.1.1	All 106 changes	Very Hard

** Important:** Rails upgrades MUST be sequential. No version skipping!
