Required

budget_name Required
string

Name for the AWS Budget. Must be unique within your AWS account. Can contain alphanumeric characters, hyphens, underscores, and periods. Maximum 100 characters.

Monthly budget limit in USD. Sets the maximum expected spend for the budget period and is used as the baseline for calculating alert thresholds.

Optional

alert_thresholds
list(number) Default: [50, 80, 100]

Percentage thresholds for budget alerts. Multiple thresholds provide early warning as spending increases. Common patterns: conservative [25, 50, 75, 90, 100], standard [50, 80, 100], aggressive [80, 100, 110].
