# Composable Mini-Apps
## Rule
Prefer many one-job apps in a workspace over one oversized app. A headless app
can own a provider, dataset, workflow, or specialist action surface without a
full UI. This architecture does not make every task a cross-app task: use the
current app's actions by default. Call a peer only when the user asks or the
outcome requires data, credentials, or a capability only that peer can provide.
A peer's availability or ability to enrich the result is not enough. The app
that owns an artifact remains responsible for authoring and editing it.
