# Save an inspected Look version

> look_reference_select: permissions and generated input/output contracts.

`look_reference_select` · Gateway release **0.8.3**

After inspecting the actual fit image, retain an immutable composite Look version with exact Character and Artifact ingredients. Records agent review; does not change Character identity, voice or any Production shot. Same preview receipt replays without another version.

Required scopes: `account:read`, `studio:write`. Changes saved state or requests work; review the operation’s effects.

Availability depends on runtime configuration and the permissions granted to this connection. Use live MCP discovery as the authority.
