Prompt tips

Name your actors

Use clear names like "User", "Payment Service", "Database".

Describe the flow

Use "first", "then", "after that" to set sequence.

Specify relationships

Mention "depends on", "calls", "triggers" for edges.

Keep it focused

One diagram per prompt produces cleaner output.

Open Digen and describe your first diagram.
