What it does

Push Notification Setup is an agent skill from secondsky/claude-skills. Implements push notifications across iOS, Android, and web using Firebase Cloud Messaging and native services. Use when adding notification capabilities, handling background messages, or setting up notification channels.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with Android, Firebase and iOS. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.

When your agent uses it

Adding notification capabilities
Handling background messages
Setting up notification channels

Example prompts

“Use the push-notification-setup skill to implement push notifications across iOS, Android, and web using Firebase Cloud Messaging and native services”
“/push-notification-setup”

What it can do on your machine

Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript, swift and kotlin).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Push Notification Setup loads about 760 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 48 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~760

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Push Notification Setup

Implement push notifications across mobile and web platforms.

Firebase Cloud Messaging (React Native)

javascript

import messaging from '@react-native-firebase/messaging';

// Request permission
async function requestPermission() {
  const status = await messaging().requestPermission();
  if (status === messaging.AuthorizationStatus.AUTHORIZED) {
    const token = await messaging().getToken();
    await sendTokenToServer(token);
  }
}

// Handle foreground messages
messaging().onMessage(async message => {
  console.log('Foreground message:', message);
  showLocalNotification(message);
});

// Handle background/quit messages
messaging().setBackgroundMessageHandler(async message => {
  console.log('Background message:', message);
});

// Handle token refresh
messaging().onTokenRefresh(token => {
  sendTokenToServer(token);
});

iOS Native (Swift)

swift

import UserNotifications

func requestAuthorization() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
        if granted {
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    sendTokenToServer(token)
}

Android (Kotlin)

kotlin

class MyFirebaseService : FirebaseMessagingService() {
    override fun onNewToken(token: String) {
        sendTokenToServer(token)
    }

    override fun onMessageReceived(message: RemoteMessage) {
        message.notification?.let {
            showNotification(it.title, it.body)
        }
    }

    private fun showNotification(title: String?, body: String?) {
        val channelId = "default"
        val notification = NotificationCompat.Builder(this, channelId)
            .setContentTitle(title)
            .setContentText(body)
            .setSmallIcon(R.drawable.ic_notification)
            .build()

        NotificationManagerCompat.from(this).notify(0, notification)
    }
}

Best Practices

Request permission at appropriate time
Handle token refresh
Support notification channels (Android)
Implement deep linking
Never send sensitive data in payload
Test on real devices
