Canon treats images as operating artifacts. A useful image does not decorate a lesson, deck, or handoff. It makes the work visible enough that an operator can decide what should happen next.
The rule is simple:
If the image cannot answer an operational question, do not use it.
The four questions
Before creating a workflow image, ask:
- What object, workflow, or system is being mapped?
- What can run, needs review, or must stop?
- What policy, contract, receipt, trace, eval, or screenshot proves the claim?
- Who owns the next step?
For an operator, this matters because the image becomes a shared instruction surface. Codex, a teammate, or a client should be able to look at it and understand the work boundary without needing a separate explanation.
Operator exercise
Pick one workflow you want Codex to help with. Write four short lines:
Object:
State:
Proof:
Owner:
If one line is empty, that is the lesson. The image is not ready yet because the workflow is not ready yet.
