Permissions are the access control layer of agent systems. They determine whether an agent can read a CRM record, send an email, edit a document, create a task, access customer data, or trigger a financial action.
For businesses, permissions are non-negotiable. A sales support agent should not have the same access as a finance agent. A reporting agent should not be able to email customers. Scope agents like employees: give them enough access to do the job, not enough access to burn down the shop.
