# Ruby > This skill should be used when conducting spec interviews or implementing specs for Ruby projects, or when the spec mentions "Ruby", "RSpec", "service objects", "Struct", or Ruby class/module patterns. Provides Ruby-specific interview and implementation checklist items. Use when this capability is needed. - Skill: `tomevault-io/ruby` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/ruby` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/ruby/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/ruby --- # Ruby Spec Interview Guide Ruby-specific checklist for spec interviews and implementation. For underlying Ruby conventions, consult the `sorah-guides:ruby` skill. Project-specific conventions always take priority. ## Interview Checklist When interviewing a spec for a Ruby project, verify these areas are fully specified: ### Architecture & Design - Service object class names, method signatures, and return types - Module/namespace hierarchy and file layout - Which value objects use Struct/Data vs plain classes - `include` vs `extend` decisions for shared behavior ### Behavior & Logic - Method signatures: keyword arguments, required vs optional parameters - Error handling: which specific exceptions are rescued and why - Nil handling strategy for each interface boundary ### Testing - RSpec structure: which spec types cover each component (unit, integration) - Factory definitions needed for test data - Error path and edge case coverage expectations ### Security - Password/credential hashing algorithm and cost factor - Token storage format (hashed, never plaintext) - Secret comparison approach (constant-time) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/sorah) — claim your Tome and manage your conversions.
