Before anyone gives a tool permission to change your data, the most useful thing it can do is help someone see that data clearly.
Reading first, writing later
Think of it as a sequence. The tool reads. Then it summarizes or organizes what it read. Then a person reviews that. Only after that does it take an action, and only a narrowly approved one.
That doesn’t mean AI has to stay read-only forever.
What the tool does and what stays with people
The tool’s job in the early stage is to work out what a read-only view needs to show. It also pulls together the information a reviewer would want in front of them before any action is switched on.
People set the access rules. People approve the actions. People stay accountable for every change. A convincing demo isn’t enough to hand over that authority. A review path that has already proven itself is.
The check to run before you approve a tool
Before approving any tool that can change your data, ask whether a read-only view of the same information would already make the work easier to understand. If it would, that is a sign to strengthen the information and the review step first, before building anything that acts.
A narrow view earns trust before a broader action surface is introduced. Once that trust exists, you can give write access, with permissions, preview, verification and rollback already defined.

Use this lesson with the AI assistant you already use
Useful AI often starts by reading, because a narrow view can earn trust before a broader action surface is introduced.
Paste the prompt, share only the context needed to answer it, and treat the result as a draft for your review. Do not include confidential information or let an AI assistant make changes without your approval.
Optional: for a visual report and saved memory, run /dxdev first.

LESSON: 2026-05-05_read-before-write
WHAT TO SHARE:
A de-identified workflow, the information people need to inspect, access boundaries, and any action someone is considering later.
ASK YOUR AGENT TO:
1. Separate confirmed facts from assumptions and unanswered questions.
2. Define the read-only information a reviewer needs.
3. Identify access, preview, and verification requirements before action.
4. List the narrowly approved prerequisites for any future write step.
RETURN:
An information-needed, access boundary, review decision, and write-prerequisite table.
BOUNDARY: Do not change records, contact anyone, route work, publish content, or act in an external system. A person must review the evidence and approve every consequential step.
