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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 74 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.01950 |
| Opus 5 | $0.00021 | $0.00975 |
| Sonnet 5 | $0.00008 | $0.00390 |
| Haiku 4.5 | $0.00004 | $0.00195 |
Grade A, and why
push-notifications 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 4d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
3. Use APNs testing tool or `curl`: How it starts
The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Push Notifications Generator
Generate push notification infrastructure with APNs registration, handling, and rich notifications.
When This Skill Activates
- User wants to add push notifications to their app
- User mentions APNs (Apple Push Notification service)
- User asks about notification categories or actions
- User wants rich notifications with images or custom UI
Pre-Generation Checks
Before generating, verify:
-
Existing Notification Code
# Check for existing notification handling grep -r "UNUserNotificationCenter\|registerForRemoteNotifications" --include="*.swift" | head -5 -
Entitlements
# Check for push notification entitlement find . -name "*.entitlements" -exec grep -l "aps-environment" {} \; -
App Delegate or SwiftUI App
# Determine app structure grep -r "@main\|UIApplicationDelegate" --include="*.swift" | head -5
Configuration Questions
1. Notification Types
- Basic - Simple alerts with title/body
- Rich - Include images, custom UI (requires Notification Service Extension)
- Both - Full notification support
2. Notification Actions
- None - Just display notifications
- Simple Actions - Quick action buttons
- Custom Categories - Multiple action categories
3. Silent Notifications
- Yes - Background data updates
- No - User-visible only

What ships with it
5 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.

push-notifications is a skill published in the GitHub repository rshankras/claude-code-apple-skills (708 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,950 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
