## Why updateBillingEmail is rated Critical

While updating an email address appears to be a Write operation, the explicit Stripe customer synchronization makes this a Financial category tool. Misuse could redirect billing communications, potentially enabling fraud or disrupting payment collection. The rate limit (30/h) and private data write further indicate sensitivity.

From the tool's own definition: "'syncs to Stripe customer' — modifying billing contact information on a payment processor (Stripe) constitutes a financial operation that could redirect invoices, affect payment flows, and disrupt billing relationships"

## Use case

AI agents use updateBillingEmail to commit financial operations through Stable Baseline, usually the final step of a payment, billing, or trading workflow. A call moves real money.
