A workable split
- Agent-appropriate: retrieval, summarization, drafting, structured field updates, scheduling within published availability.
- Human-approved: sending to customers, financial documents, deletions, overrides.
- Human-only: role and permission changes, billing configuration, administrative and platform-level surfaces.
External assistant versus platform-native operator
A third-party assistant connected over a protocol is a consumer of a scoped interface. It sees the tools it was granted, acts as one user, and has no privileged path. The platform's own operator — with the full identity envelope, business context and audit trail — is a different role and stays inside the platform.
Blurring the two is how a convenience integration quietly becomes an administrative back door.
Why parity claims should be resisted
It is tempting to say an agent can do everything a person can. In practice, coverage grows action by action, each one reviewed, permission-mapped and confirmed where it should be. Describing that as finished misleads buyers and, worse, encourages teams to stop checking.
