Ruby Rules

These rules come from app/rules/ruby/ in ai-toolkit. They cover the project's standards for coding style, frameworks, patterns, security, and testing in Ruby. Apply them when writing or reviewing Ruby code.

Ruby Coding Style

Naming

• PascalCase: classes, modules.
• snake_case: methods, variables, file names, directories.
• UPPER_SNAKE: constants (MAX_RETRIES = 3).
• Prefix boolean methods with predicate: empty?, valid?, admin?.
• Suffix dangerous methods with !: save!, sort!, strip!.
• Use _ prefix for intentionally unused variables: _unused.
