RISK

Why estimates_unsell is rated Medium

The tool performs a reversible modification to estimate data (unselling/canceling an estimate). This is categorized as Write rather than Destructive because 'unsell' typically reverses or voids an estimate rather than permanently deleting it. High severity due to potential business impact on sales records and financial workflows in a service management platform.

From the tool's definition Tool name 'estimates_unsell' indicates reversal or cancellation of an estimate, which modifies data state. The verb 'unsell' suggests removing or reversing a sales estimate, a write operation. Description is empty, reducing confidence.
