+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+This is a Ruby gem (`reqif`) that parses and generates ReqIF (Requirements Interchange Format) XML documents. ReqIF is an OMG standard (v1.2) for exchanging requirements between different tools. The gem is part of the `lutaml` family.
+
+## Commands
+
+```bash
+bundle install          # Install dependencies
+bundle exec rake        # Run specs + rubocop (default)
+bundle exec rake spec   # Run specs only
+bundle exec rake rubocop  # Run linter only
+bundle exec rspec spec/reqif_spec.rb  # Run a single spec file
+bundle exec bin/console # Start an IRB console with the gem loaded
+```
+
+## Architecture
+
+### Framework: lutaml/model
+
+All model classes inherit from `Lutaml::Model::Serializable` and use an `xml` DSL block to define XML serialization. The gem uses `Lutaml::Model::XmlAdapter::NokogiriAdapter` for XML parsing/generation.
+
+### Class-per-file pattern
+
+Each ReqIF concept is a separate class in `lib/reqif/`. Classes follow a consistent structure:
+
+```ruby
+module Reqif
+  class Foo < Lutaml::Model::Serializable
+    attribute :bar, :string
+    attribute :baz, SomeOtherClass
+
+    xml do
+      element "FOO"
+      namespace "http://www.omg.org/spec/ReqIF/20110401/reqif.xsd"
+      map_attribute "BAR", to: :bar
+      map_element "BAZ", to: :baz
+    end
+  end
+end
+```
+
+### Key model classes
+
+- `ReqIf` — Root element, contains `THE-HEADER`, `CORE-CONTENT`, `TOOL-EXTENSIONS`
+- `ReqIfContent` — Contains `DATATYPES`, `SPEC-TYPES`, `SPEC-OBJECTS`, `SPEC-RELATIONS`, `SPECIFICATIONS`, `SPEC-RELATION-GROUPS`
+- `SpecObject` — A single requirement with attributes (identifier, long_name, desc, etc.) and `VALUES`
+- `Specification` — A container/hierarchy that has `CHILDREN` referencing other specs
+- `SpecRelation` — A relation between two specs with `SOURCE` and `TARGET` references
+- `Values` — Container for `AttributeValue` elements (boolean, date, enumeration, integer, real, string, xhtml)
+- `Type` / `SpecObjectType` / `SpecificationType` — Type definitions for spec objects/specifications
+- `Datatypes` — Container for datatype definitions (boolean, date, enumeration, integer, real, string, xhtml)
+
+### Attribute naming conventions
+
+XML element names use uppercase-kebab-case (e.g., `SPEC-OBJECT`, `LAST-CHANGE`) while Ruby attributes use snake_case (e.g., `spec_object`, `last_change`). The `map_element` and `map_attribute` DSL methods handle the translation.
+
+### Autoloading
+
+Zeitwerk is used for autoloading. `lib/reqif.rb` sets up the loader and eager loads all classes.
+
+### XML round-trip testing
+
+Round-trip tests in `spec/reqif_spec.rb` parse fixture XML files, regenerate XML via `to_xml`, and compare canonicalization using `xml-c14n`. All fixture files under `spec/fixtures/` (`.xml`, `.reqif`) are automatically included.
+
+### Style
+
+- String literals: double quotes enforced by RuboCop
+- Ruby version: 3.0+
+- Frozen string literals: required at the top of every file
