Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00081 | $0.01383 |
| Opus 5 | $0.00041 | $0.00691 |
| Sonnet 5 | $0.00016 | $0.00277 |
| Haiku 4.5 | $0.00008 | $0.00138 |
Grade A, and why
silent-pushes-setup 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Background Push Setup And Diagnosis
Apple calls these background notifications. "Silent push" is the common name for an APNs device notification that wakes the app without an alert, sound, or badge.
Scope
Use this skill for an iOS or iPadOS app that receives
apns-push-type: background notifications. Keep these adjacent concerns out of
scope:
- visible alerts, local notifications, notification service extensions, and authorization UX;
- Live Activity, PushKit, VoIP, File Provider, and broadcast push types;
- Firebase, other provider SDKs, provider credential provisioning, and widget refresh policy.
Do not use background push for urgent, guaranteed, or periodic execution. The app must reconcile current server state when it next runs because delivery may be delayed, coalesced, throttled, or dropped.
Audit Workflow
1. Establish The Signed Environment
Record the app bundle ID, signed aps-environment value, device-token source,
and provider endpoint. Do not infer the APNs environment from a scheme or
configuration name.
developmentusesapi.sandbox.push.apple.com.production, including prerelease and beta distribution, usesapi.push.apple.com.- Xcode derives
aps-environmentfrom the provisioning profile. Verify the signed app, not only the source entitlement file or Xcode UI.
2. Verify Capabilities And Registration
The app target needs both:
- Push Notifications, which adds the iOS
aps-environmententitlement; - Background Modes > Remote notifications, which permits background notification handling.
Call registerForRemoteNotifications() on each launch. Handle both registration
callbacks and forward every successful token callback to the provider. Treat
the token as opaque and variable-length; do not cache it locally as truth or
assume a fixed size. Bind provider records to the token, topic, and APNs
environment.
Alert authorization is separate. registerForRemoteNotifications() can obtain
a token for background delivery without first requesting permission for alerts,
sounds, or badges.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

silent-pushes-setup is a skill published in the GitHub repository fiveonecode/agent-skills (19 stars, last pushed 11d ago), licensed MIT. It adds 81 tokens to every session and 1,383 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
