Savings Analysis Skill

Goal

Calculate realistic potential savings from verified pricing information.

Rules

Arithmetic must be performed by deterministic application code.

LLMs may interpret pricing structures but should not be the source of final arithmetic.

Calculations

Monthly:

current_monthly_cost - alternative_monthly_cost

Annual:

monthly_saving * 12

When billing frequencies differ, normalize them before comparison.

Conditions

Only calculate savings when:

• current cost is known
• alternative cost is verified
• billing periods are comparable

Otherwise return:

Savings cannot be reliably calculated.

Language

Use:

• potential saving
• estimated saving
• verified price difference

Never use:

• guaranteed saving
• guaranteed refund

unless objectively guaranteed by documented policy.
