Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nylo-notifications scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Nylo Local Notifications

Overview

Nylo v7 provides a LocalNotification class for sending immediate or scheduled local notifications on iOS and Android. It wraps platform-specific notification APIs behind a fluent builder pattern, with static convenience methods for common operations. Local notifications are not supported on web and will throw a NotificationException if attempted.

When to Use

  • Sending immediate local notifications to the user
  • Scheduling notifications for a future date/time
  • Configuring Android notification channels (importance, vibration, LEDs, sounds)
  • Configuring iOS notification presentation (banners, alerts, badges, interruption level)
  • Attaching media to iOS notifications
  • Handling notification permissions
  • Cancelling or clearing notifications
  • Managing app badge counts
  • When NOT to use: For push notifications from a remote server, use a dedicated push notification service (e.g., Firebase Cloud Messaging). This skill covers local-only notifications.

Quick Reference

Action Code
Send immediately await LocalNotification(title: "Hi", body: "World").send()
Send with helper await localNotification("Hi", "World").send()
Send via static method await LocalNotification.sendNotification(title: "Hi", body: "World")
Schedule for later .send(at: DateTime.now().add(Duration(hours: 1)))
Add payload .addPayload("order_id:456")
Set notification ID .addId(42)
Add subtitle .addSubtitle("From support")
Set badge number .addBadgeNumber(3)
Custom sound .addSound("alert.wav")
iOS attachment .addAttachment("https://example.com/img.jpg", "img.jpg")
Android config .setAndroidConfig(AndroidNotificationConfig(...))
iOS config .setIOSConfig(IOSNotificationConfig(...))
Cancel by ID await LocalNotification.cancelNotification(42)
Cancel all await LocalNotification.cancelAllNotifications()
Request permissions await LocalNotification.requestPermissions()
Clear badge count await LocalNotification.clearBadgeCount()

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
