axiom-push-notifications-diag

axiom-push-notifications-diag is a skill for Claude Code, Codex from ComeOnOliver/skillshub. It costs 72 tokens per session (5,568 once invoked), scanned A, original, MIT.

A troubleshooting guide for iOS push notifications, which are alerts or updates delivered to an app by Apple’s notification service. It covers registration, environment, permissions, payloads, extensions, and delivery timing.

In plain words
What is it for?
Use it to investigate device-token errors, provisioning mismatches, invalid payloads, Focus filtering, silent-push limits, and notification-service extension failures.
Why use it?
It helps identify why notifications are missing, work only in development, fail silently, or stop updating a Live Activity.

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

axiom-push-notifications-diag scanned grade A with 1 finding 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 9d 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.

Push Notification Diagnostics

Systematic troubleshooting for push notification failures: missing notifications, token registration errors, environment mismatches, silent push throttling, and service extension problems.

Overview

Core Principle: When push notifications don't work, the problem is usually:

  1. Token/registration failures (never registered, wrong format, expired) — 30%
  2. Entitlement/provisioning mismatch (capability missing, wrong environment) — 25%
  3. Payload structure errors (missing keys, wrong types, invalid JSON) — 15%
  4. Focus/interruption suppression (iOS 15+ filtering, provisional auth) — 15%
  5. Service extension failures (timeout, crash, missing mutable-content) — 10%
  6. Delivery timing/throttling (silent push budget, APNs coalescing) — 5%

Always verify entitlements and token registration BEFORE debugging payload or delivery logic.

Red Flags

Symptoms that indicate push-specific issues:

Symptom Likely Cause
No notifications at all Missing Push Notification capability or provisioning profile
Works in dev, not production Sending to sandbox APNs with production token (or vice versa)
Token registration fails on Simulator Expected — Simulator cannot register for remote notifications
Notifications appear without sound Missing .sound in authorization options or payload
Rich notification shows plain text Missing mutable-content: 1 in payload
Image not showing in notification Service extension failed silently — check serviceExtensionTimeWillExpire
Silent push not waking app System throttling (~2-3/hour), or app was force-quit by user
Notifications stopped after iOS update Focus mode enabled by default in iOS 15+; check interruption level
Badge shows wrong number Multiple notifications sent without explicit badge count reset
Actions not appearing Category identifier mismatch between payload and registered categories
Notification appears twice Both local and remote notification scheduled for same event
FCM works on Android, not iOS Missing APNs auth key upload in Firebase Console
