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 5.1 | $0.00028 | $0.02405 |
| Opus 5 | $0.00014 | $0.01203 |
| Sonnet 5 | $0.00006 | $0.00481 |
| Haiku 4.5 | $0.00003 | $0.00241 |
Grade A, and why
push-notifications 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 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.
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.

Push Notifications
Overview
Web push notifications deliver timely messages to subscribers even when they are not on your site — for back-in-stock alerts, price drops, and cart reminders. Push requires explicit browser permission, making the opt-in prompt timing critical. For Shopify, WooCommerce, and BigCommerce, dedicated push notification apps (PushOwl, OneSignal) handle all the subscriber management, triggering logic, and delivery without custom service worker code.
When to Use This Skill
- When adding back-in-stock notifications to replace static "notify me" email forms
- When recovering abandoned carts via a browser push channel alongside email
- When building a price-watch feature for wishlisted items
- When email deliverability is poor and a supplemental channel is needed
- When targeting mobile-first markets where push opt-in rates exceed email opt-in
Core Instructions
Step 1: Choose the right push notification platform
| Platform | Best For | Shopify | WooCommerce | BigCommerce | Price |
|---|---|---|---|---|---|
| PushOwl | Shopify-native, back-in-stock + abandonment | App Store | — | — | Free tier; $19+/mo |
| OneSignal | All platforms, free tier, highly configurable | Via JS tag | Plugin | Via JS tag | Free tier; $9+/mo |
| Klaviyo Web Push | Already using Klaviyo for email | App Store | Plugin | App Marketplace | Included in Klaviyo |
| PushEngage | WooCommerce + segmented campaigns | — | Plugin | Via JS tag | Free tier; $9+/mo |
Shopify recommendation: Use PushOwl — it's the most integrated Shopify push app with built-in back-in-stock, cart abandonment, and shipping alerts.
WooCommerce recommendation: Use PushEngage or OneSignal — both have WordPress plugins and handle subscriber management automatically.
Step 2: Set up push notifications
Shopify with PushOwl
- Install PushOwl from the Shopify App Store
- Go to PushOwl → Settings → Opt-in Prompt and configure:
- Delay the prompt: set it to trigger after a customer views 2+ pages or adds an item to cart
- Opt-in message: "Get notified when items are back in stock and for price drops"
- Go to PushOwl → Automations → Back in Stock and enable it — PushOwl automatically adds a "Notify Me" button to out-of-stock products and fires the push when inventory is replenished
- Go to PushOwl → Automations → Cart Abandonment and enable it:
- Set timing: 1 hour after abandonment, then 24 hours
- Customize the notification message and the cart recovery URL
- Go to PushOwl → Campaigns to send broadcast push notifications for sales, new arrivals, or flash discounts

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.
