From the source SKILL.md

Activate this skill when an Apex class has grown past the point where one class can comfortably hold all its responsibilities, when a trigger handler embeds SOQL, or when a service class has started issuing its own queries. The goal is the lightweight enterprise pattern this repo standardises on: a clear split into Trigger handler → Domain → Service → Selector, anchored by the canonical base classes in templates/apex/.
