# Notifications Skill

## Applicability

- **Platforms:** iOS and Android
- **React Native:** 0.76+ (New Architecture interop assumed unless a checklist item says otherwise)

## When to Use

- Registering for push or scheduling a local notification
- Handling a tap that opens a screen from the background or a killed app
- Reviewing what the payload contains and when permission is requested

Permission prompts in general belong to [native-integration](../native-integration/SKILL.md). Whether a deep link target is allowed belongs to [security](../security/SKILL.md).

## Severity

- **Merge-blocking:** the payload can navigate to an arbitrary screen, or the background handler is registered inside a component.
- **Should-fix:** channel names and when the permission prompt appears.

## Guidance

### Permission and registration

- [ ] Notification permission is requested when the user asks for alerts, not at first launch
- [ ] Denied and revoked states skip registration and do not loop the prompt
- [ ] The device token is sent to the server after it changes, and removed from the server on sign-out

### Delivery

The background handler is registered from the application entry file, not from inside a component. Cold-start order (restore the session, then consume the tap once) is owned by [architecture](../architecture/SKILL.md).

- [ ] The background handler is registered at startup, outside the React tree
- [ ] Foreground, background, and killed-app taps all open the same destination
- [ ] The destination is one of the allowed routes (see [security](../security/SKILL.md))
- [ ] A tap that arrives before navigation is ready is stored and consumed once
- [ ] Android channels exist for the categories the user can tell apart; iOS uses a purpose the user can understand

**Incorrect:**
```tsx
function onNotification(remoteMessage) {
  navigation.navigate(remoteMessage.data.screen, remoteMessage.data);
}
```

**Correct:**
```tsx
function onNotification(remoteMessage) {
  const route = parseNotificationRoute(remoteMessage.data);
  if (!route) return;
  navigation.navigate(route.name, route.params);
}
```

### Privacy

- [ ] The visible title and body, and the data payload, contain no payment data, tokens, or more personal detail than the user needs to recognise the alert
- [ ] Marketing or non-essential alerts are not scheduled when consent is off (see [security](../security/SKILL.md))

## Anti-Patterns

| Anti-Pattern | Risk | Fix |
|---|---|---|
| Navigating from the raw payload | Opens an arbitrary screen or crashes on a missing param | Parse into a fixed set of routes |
| Registering a new token without deleting the old one on logout | The previous user receives the next user's alerts | Delete the token server-side on sign-out |

## Pitfalls

- A killed-app tap is delivered on the next cold start, before navigation exists. Store it and consume it after the session is restored.
- Background delivery limits differ by platform; a handler that does network work can be suspended before it finishes.
