Andrew Kane Gem Writer

Write Ruby gems following Andrew Kane's battle-tested patterns from 100+ gems with 374M+ downloads (Searchkick, PgHero, Chartkick, Strong Migrations, Lockbox, Ahoy, Blazer, Groupdate, Neighbor, Blind Index).

Core Philosophy

Simplicity over cleverness. Zero or minimal dependencies. Explicit code over metaprogramming. Rails integration without Rails coupling. Every pattern serves production use cases.

Entry Point Structure

Every gem follows this exact pattern in lib/gemname.rb:

# 1. Dependencies (stdlib preferred)
require "forwardable"

# 2. Internal modules
require_relative "gemname/model"
require_relative "gemname/version"
