Create Service Object Task

Problem

A Ruby team needs help with a task in this area:

Use when creating or refactoring Ruby service classes with def self.call(...)→new(...).call entry point, {success: true/false, response: {...}} response contract (error: {success: false, response: {error: {message: string}}}), must catch StandardError + log with logger.error + use UPPER_SNAKE_CASE error constants, spec at spec/services/[module]/[name]_spec.rb, impl at services/[module]/[name].rb, mandatory module README even for single-service modules, tests assert success: and response: keys, test command+failure output in artifact — and MUST write failing test BEFORE implementation.

The team has asked for a concise implementation artifact that a reviewer can inspect without needing to observe the agent's process.

Output

Create answer.md with:

• a short plan for the work
• the concrete Ruby-oriented artifact or recommendation
• the verification steps or quality gates that should be run
• any assumptions that affect the result
