System prompt
The page at /dashboard/prompt shows Matilda's complete system prompt, read-only. It is reached from the View memory link on Setup.
This is the single best way to understand how Matilda behaves: her identity and tone, when she uses a tapback instead of text, the intake order, how she treats the known contact block, and the boundaries she will not cross.
The prompt is part of the application code and is not editable from the dashboard. Changes ship with a release.
