# TimeSafari Notifications — LLM Implementation Directive (v2.0) |
|||
_Last updated: August 12, 2025_ |
|||
|
|||
## 0) Role & Objective |
|||
**You are the implementation LLM.** Build an **offline-first daily notifications system** for Android (Kotlin) and iOS (Swift) that **prefetches -> caches -> schedules -> displays** content **without requiring network at display time**. Favor **reliability over richness**. |
|||
|
|||
## 1) Golden Rules |
|||
1. **Follow the pipeline:** **Prefetch → Cache → Schedule → Display.** |
|||
2. **Never depend on network at display time.** All assets must be local. |
|||
3. **Design for failure.** Always have a last-known-good and an emergency fallback. |
|||
4. **Keep content scannable (<3s), single message, actionable.** |
|||
5. **Measure everything** (fetch success, delivery, engagement, stale usage). |
|||
6. **Minimize battery impact** and respect platform limitations and user settings. |
|||
7. **Ask only when needed:** if a required input is missing, use the defaults below; otherwise proceed. |
|||
|
|||
## 2) Default Assumptions (use unless overridden) |
|||
- **Product mode:** Lightweight Daily Updates (text + emoji) with option to extend to media later. |
|||
- **Fetch size:** 1–2 KB JSON daily. |
|||
- **User schedule default:** 07:30 local time, daily. |
|||
- **Quiet hours:** None (app-level quiet hours supported but disabled by default). |
|||
- **Analytics:** Local log + pluggable uploader (no-op by default). |
|||
|
|||
## 3) Deliverables |
|||
Produce the following artifacts: |
|||
|
|||
### Android (Kotlin) |
|||
- `:core`: models, storage, metrics, fallback manager. |
|||
- `:data`: fetchers (WorkManager), mappers, cache policy. |
|||
- `:notify`: scheduler (AlarmManager), receiver, channels. |
|||
- App manifest entries & permissions. |
|||
- Unit tests for fallback, scheduling, metrics. |
|||
- README with battery optimization instructions (OEMs). |
|||
|
|||
### iOS (Swift) |
|||
- `NotificationKit`: models, storage, metrics, fallback manager. |
|||
- BGTaskScheduler registration + handler. |
|||
- UNUserNotificationCenter scheduling + categories + attachments. |
|||
- Unit tests for fallback, scheduling, metrics. |
|||
- README with Background App Refresh caveats + Focus/Summary notes. |
|||
|
|||
## 4) Permissions & Required Setup |
|||
### Android Manifest |
|||
```xml |
|||
<uses-permission android:name="android.permission.INTERNET" /> |
|||
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" /> |
|||
<uses-permission android:name="android.permission/SCHEDULE_EXACT_ALARM" /> |
|||
<uses-permission android:name="android.permission.WAKE_LOCK" /> |
|||
``` |
|||
- Create a high-importance **NotificationChannel** `timesafari.daily`. |
|||
- If **SCHEDULE_EXACT_ALARM** denied on Android 12+, auto-fallback to inexact. |
|||
|
|||
### iOS App Setup (AppDelegate / SceneDelegate) |
|||
- Register `BGTaskScheduler` with ID `com.timesafari.daily-fetch`. |
|||
- Request alerts, sound, badge via `UNUserNotificationCenter`. |
|||
- Create category `DAILY_UPDATE` with a primary `View` action. |
|||
- Ensure Background Modes: **Background fetch**, **Remote notifications** (optional for future push). |
|||
|
|||
## 5) Data Model (keep minimal, versioned) |
|||
### Canonical Schema (language-agnostic) |
|||
``` |
|||
NotificationContent v1 |
|||
- id: string (uuid) |
|||
- title: string |
|||
- body: string (plain text; may include simple emoji) |
|||
- scheduledTime: epoch millis (client-local target) |
|||
- mediaUrl: string? (for future; must be mirrored to local path before use) |
|||
- fetchTime: epoch millis |
|||
``` |
|||
### Kotlin |
|||
```kotlin |
|||
@Entity |
|||
data class NotificationContent( |
|||
@PrimaryKey val id: String, |
|||
val title: String, |
|||
val body: String, |
|||
val scheduledTime: Long, |
|||
val mediaUrl: String?, |
|||
val fetchTime: Long |
|||
) |
|||
``` |
|||
### Swift |
|||
```swift |
|||
struct NotificationContent: Codable { |
|||
let id: String |
|||
let title: String |
|||
let body: String |
|||
let scheduledTime: TimeInterval |
|||
let mediaUrl: String? |
|||
let fetchTime: TimeInterval |
|||
} |
|||
``` |
|||
|
|||
## 6) Storage Layers |
|||
**Tier 1: Key-Value (quick)** — next payload, last fetch timestamp, user prefs. |
|||
**Tier 2: DB (structured)** — history, media metadata, analytics events. |
|||
**Tier 3: Files (large assets)** — images/audio; LRU cache & quotas. |
|||
|
|||
- Android: SharedPreferences/DataStore + Room + `context.cacheDir/notifications/` |
|||
- iOS: UserDefaults + Core Data/SQLite + `Library/Caches/notifications/` |
|||
|
|||
## 7) Background Execution |
|||
### Android — WorkManager |
|||
- Periodic daily work with constraints (CONNECTED network). |
|||
- Total time budget ~10m; use **timeouts** (e.g., fetch ≤30s, overall ≤8m). |
|||
- On exception/timeout: **schedule from cache**; then `Result.success()` or `Result.retry()` per policy. |
|||
|
|||
### iOS — BGTaskScheduler |
|||
- `BGAppRefreshTask` with aggressive time budgeting (10–30s typical). |
|||
- Submit next request immediately at start of handler. |
|||
- Set `expirationHandler` first; cancel tasks cleanly; **fallback to cache** on failure. |
|||
|
|||
## 8) Scheduling & Display |
|||
### Android |
|||
- Prefer `AlarmManager.setExactAndAllowWhileIdle()` if permitted; else inexact. |
|||
- Receiver builds notification using **BigTextStyle** for long bodies. |
|||
- Limit actions to ≤3; default: `View` (foreground intent). |
|||
|
|||
### iOS |
|||
- `UNCalendarNotificationTrigger` repeating at preferred time. |
|||
- Category `DAILY_UPDATE` with `View` action. |
|||
- Media attachments **only if local**; otherwise skip gracefully. |
|||
|
|||
## 9) Fallback Hierarchy (must implement) |
|||
1. **Foreground prefetch path** if app is open. |
|||
2. **Background fetch** with short network timeout. |
|||
3. **Last good cache** (annotate staleness: “as of X”). |
|||
4. **Emergency phrases** (rotate from static list). |
|||
|
|||
Provide helper: |
|||
- `withStaleMarker(content) -> content'` appends age label (e.g., “from 3h ago”). |
|||
|
|||
## 10) Failure Matrix & Responses |
|||
| Scenario | Detect | Action | |
|||
|---|---|---| |
|||
| No network / timeout | Exceptions / status | Use last-good; schedule | |
|||
| Invalid JSON | Parse error | Use emergency content; log | |
|||
| Storage full | Write error | Evict old; retry minimal payload | |
|||
| Notifications disabled | OS state | In-app education screen | |
|||
| Background killed | Gaps in execution | Catch-up next foreground open | |
|||
|
|||
## 11) Metrics (local first; uploader optional) |
|||
Track per attempt: |
|||
``` |
|||
NotificationMetrics v1 |
|||
- scheduledTime, actualDeliveryTime? |
|||
- contentAge (ms) |
|||
- engagement: {TAPPED, DISMISSED, IGNORED}? |
|||
- failureReason? |
|||
- platformInfo (oem, os version, app state) |
|||
``` |
|||
- Compute: **Fetch Success Rate**, **Delivery Rate**, **Engagement Rate**, **Stale Content Rate**. |
|||
|
|||
## 12) Testing Requirements |
|||
### Matrix (minimum) |
|||
- Android 12+ foreground/background/killed; with/without Battery Saver; Wi‑Fi/Mobile/Offline. |
|||
- iOS 16+ background/Low Power/Focus/Scheduled Summary on & off. |
|||
- Offline at trigger time (must still display). |
|||
|
|||
### Unit Tests (examples) |
|||
- Fallback when fetch fails (uses last-good and marks stale). |
|||
- Exact vs inexact scheduling path selected correctly. |
|||
- Metrics recorded for each stage. |
|||
|
|||
## 13) UX Standards |
|||
- One clear message; no clutter. |
|||
- ≤2 actions; primary takes user into app. |
|||
- Respect quiet hours if configured. |
|||
- Provide onboarding: value explanation → permission request → time picker → test notification → tips for OEM battery settings (Android) or Focus/Summary (iOS). |
|||
|
|||
## 14) Code Stubs (must generate & wire) |
|||
### Android — Worker (core pattern) |
|||
```kotlin |
|||
class DailyContentWorker(ctx: Context, params: WorkerParameters) : CoroutineWorker(ctx, params) { |
|||
override suspend fun doWork(): Result = try { |
|||
withTimeout(8.minutes) { |
|||
val content = fetchDailyContent(timeout = 30.seconds) |
|||
saveToCache(content) |
|||
scheduleNotification(content) |
|||
} |
|||
Result.success() |
|||
} catch (e: TimeoutCancellationException) { |
|||
scheduleFromCache(); Result.success() |
|||
} catch (e: Exception) { |
|||
scheduleFromCache(); Result.retry() |
|||
} |
|||
} |
|||
``` |
|||
### iOS — BG Refresh Handler (core pattern) |
|||
```swift |
|||
func handleBackgroundRefresh(_ task: BGAppRefreshTask) { |
|||
scheduleNextRefresh() |
|||
var finished = false |
|||
task.expirationHandler = { if !finished { cancelNetwork(); task.setTaskCompleted(success: false) } } |
|||
fetchDailyContent(timeout: 15) { result in |
|||
defer { finished = true; task.setTaskCompleted(success: result.isSuccess) } |
|||
switch result { |
|||
case .success(let content): quickSave(content); scheduleNotification(content) |
|||
case .failure: scheduleFromCache() |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|
|||
## 15) Security & Privacy |
|||
- Use HTTPS; pin if required. |
|||
- Strip PII from payloads; keep content generic by default. |
|||
- Store only what is necessary; apply cache quotas; purge on logout/uninstall. |
|||
- Respect OS privacy settings (Focus, Scheduled Summary, Quiet Hours). |
|||
|
|||
## 16) Troubleshooting Playbook (LLM should generate helpers) |
|||
- Android: verify permission, channel, OEM battery settings; `adb shell dumpsys notification`. |
|||
- iOS: check authorization, Background App Refresh, Low Power, Focus/Summary state. |
|||
|
|||
## 17) Roadmap Flags (implement behind switches) |
|||
- `FEATURE_MEDIA_ATTACHMENTS` (default off). |
|||
- `FEATURE_PERSONALIZATION_ENGINE` (time/frequency, content types). |
|||
- `FEATURE_PUSH_REALTIME` (server-driven for urgent alerts). |
|||
|
|||
## 18) Definition of Done |
|||
- Notifications deliver daily at user-selected time **without network**. |
|||
- Graceful fallback chain proven by tests. |
|||
- Metrics recorded locally; viewable log. |
|||
- Clear onboarding and self-diagnostic screen. |
|||
- Battery/OS constraints documented; user education available. |
|||
|
|||
## 19) Quick Start (LLM execution order) |
|||
1. Scaffold modules (Android + iOS). |
|||
2. Implement models + storage + fallback content. |
|||
3. Implement schedulers (AlarmManager / UNCalendarNotificationTrigger). |
|||
4. Implement background fetchers (WorkManager / BGTaskScheduler). |
|||
5. Wire onboarding + test notification. |
|||
6. Add metrics logging. |
|||
7. Ship minimal, then iterate. |
|||

|||
- "💪 Every small step forward counts. You've got this!" |
|||
- "🎯 Focus on what you can control today." |
|||
- "✨ Your potential is limitless. Keep growing!" |
