What problem does it solve?

This Skill teaches how to sum variables across entities using declarative adds or the add() function, reducing boilerplate code and errors.

Core Features & Use Cases

• Simple sums with adds: Define adds to sum across members without a formula.
• Complex sums with add(): Use add() to incorporate conditions or transformations.
• Use Case: Aggregate multiple income streams across a household with minimal code.

Quick Start

Define a final variable that uses adds = ["employment_income", "self_employment_income"] to compute total earned income.
