+# Ruby Language Prompt Snippet
+
+## Key Concepts
+
+- **Blocks/Procs/Lambdas**: First-class callable objects; blocks are implicit, procs and lambdas are explicit
+- **Mixins (include/extend)**: Share behavior across classes via modules without inheritance
+- **Metaprogramming**: Dynamic method definition (`define_method`), interception (`method_missing`)
+- **Duck Typing**: Objects are defined by what they can do, not what class they are
+- **DSLs**: Domain-specific languages built using blocks and metaprogramming (e.g., Rails routes)
+- **Monkey Patching**: Reopening existing classes to add or modify methods at runtime
+- **Symbols**: Immutable, interned strings (`:name`) used as identifiers and hash keys
+- **Open Classes**: Any class can be reopened and extended at any point in the program
+- **Enumerable Module**: Mixin providing collection methods (map, select, reduce) to any class with `each`
+
+## Import Patterns
+
+- `require 'gem_name'` — load a gem or standard library module
+- `require_relative './file'` — load a file relative to the current file's directory
+- `load 'file.rb'` — load and re-execute a file (unlike require, does not cache)
+- `autoload :ClassName, 'path'` — lazy loading of constants on first reference
+
+## File Patterns
+
+- `Gemfile` — dependency declarations managed by Bundler
+- `Rakefile` — task definitions (Ruby's make equivalent)
+- `spec/` — RSpec test directory with `*_spec.rb` convention
+- `test/` — Minitest directory with `test_*.rb` or `*_test.rb` convention
+- `config.ru` — Rack application entry point for web servers
+- `lib/` — main source code directory by convention
+
+## Common Frameworks
+
+- **Rails** — Full-stack web framework following convention over configuration
+- **Sinatra** — Minimal DSL for creating web applications quickly
+- **RSpec** — Behavior-driven testing framework with expressive DSL
+- **Sidekiq** — Background job processing using Redis-backed queues
+- **Grape** — REST API micro-framework for Ruby
+
+## Example Language Notes
+
+> Uses `method_missing` to dynamically delegate attribute access to the wrapped model
+> object. When a method is not found on the decorator, it falls through to the model,
+> providing transparent delegation without explicit forwarding methods.
+>
+> Rails relies heavily on convention over configuration — file placement in `app/models/`,
+> `app/controllers/`, etc. determines behavior without explicit registration.
