Maui Push Notifications

What it does

When your agent uses it

• : push notification
• Firebase Cloud Messaging
• Azure Notification Hubs
• Device registration

Example prompts

• “push notification”
• “Firebase Cloud Messaging”
• “Azure Notification Hubs”
• “/maui-push-notifications”

What it can do on your machine

Read from SKILL.md and the folder at commit 79bb4bf. 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 csharp).

  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

Maui Push Notifications loads about 1.2k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 173 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~173

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.9k

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

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.

description

End-to-end guide for adding push notifications to .NET MAUI apps. Covers Firebase Cloud Messaging (Android), Apple Push Notification Service (iOS), Azure Notification Hubs as the cross-platform broker, an ASP.NET Core backend API, and the MAUI client wiring on every platform. USE FOR: "push notification", "FCM", "APNS", "Firebase Cloud Messaging", "Azure Notification Hubs", "device registration", "remote notification", "send push notification", "notification token". DO NOT USE FOR: local/scheduled notifications (use maui-local-notifications), general permission handling (use maui-permissions), or background tasks without notifications (use maui-app-lifecycle).

// ❌ Relative URIs resolve incorrectly
_http = new HttpClient { BaseAddress = new Uri("https://example.com") };

// ✅ Trailing slash required
_http = new HttpClient { BaseAddress = new Uri("https://example.com/") };

// ❌ Only registering once at startup
// (token may change later without re-registration)

// ✅ Always re-register in OnNewToken
public override void OnNewToken(string token)
{
    var svc = IPlatformApplication.Current?.Services.GetService<IPushNotificationService>();
    if (svc is null) return;
    svc.Token = token;
    _ = svc.RegisterAsync();
}

// ✅ Batch tags to stay under the limit
var batches = request.Tags.Chunk(20);
foreach (var batch in batches)
{
    var tagExpr = string.Join(" || ", batch);
    await _hub.SendFcmV1NativeNotificationAsync(payload, tagExpr, ct);
}
