The AI agent working for you probably has more access than you do
Say a sales rep uses an AI assistant to help manage their pipeline. The rep has role-based access to Salesforce, scoped to their territory and their accounts. The assistant, wired in through an API integration, often doesn't have that same scoping. It authenticates as a service account with broad read and write access across the org, because that was faster to set up than a permission model that matches what the actual user is allowed to see.
