The first helpful step is often helping someone see the right information clearly before anyone gives a tool permission to change it.

## Earn write authority after the review path works

Read before write is a progression: read, summarize or organize, human review, then narrowly approved action. The point is not that AI must always remain read-only. It is that write authority should be introduced deliberately after the team knows what information, permissions, preview, verification, and rollback are required.

Start by asking whether a read-only view would already make the work easier to understand. If it would, that is evidence to strengthen the information and review path before adding an action surface.

## Where AI fits

AI can identify what a read-only view needs to show and organize the information a reviewer would need before any action is enabled.

## The human decision

People set access rules, approve actions, and remain accountable for changes. Write authority should follow a proven review path, not a convincing demo.

## The lesson

Useful AI often starts by reading, because a narrow view can earn trust before a broader action surface is introduced.

The Build Log companion follows a portal that became useful only after its creators stopped treating write access as the first measure of agency.
