## Why delete_promotion is rated Critical

This tool permanently removes promotional entities from the system, which cannot be undone. While historical usage data survives, the promotion configuration, terms, and active deployments are destroyed. For a CRM managing customer incentives and business operations, deleting a promotion could disrupt ongoing marketing campaigns, customer expectations, and business logic tied to that promotion.

From the tool's own definition: "Tool name 'delete_promotion' with description stating 'Delete a promotion' indicates irreversible removal of promotional data. The clarification that 'past usage records are preserved' confirms the promotion itself is permanently deleted."

## Use case

AI agents call delete_promotion to permanently remove resources in FavCRM, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
