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 | $0.00033 | $0.02505 |
| Opus 5 | $0.00016 | $0.01252 |
| Sonnet 5 | $0.00007 | $0.00501 |
| Haiku 4.5 | $0.00003 | $0.00250 |
Grade B, and why
paypal-integration scanned grade B 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

PayPal Integration
Overview
PayPal Checkout lets shoppers pay using their PayPal balance, Venmo, Pay Later (installments), or a card processed by PayPal. It is particularly valuable in Germany, Netherlands, and Brazil where PayPal is the dominant payment method, and in any market where customers prefer not to enter card details. All major platforms have official PayPal integrations that require only credentials — no custom code needed for standard checkout.
When to Use This Skill
- When adding PayPal as a payment option alongside a card processor
- When implementing PayPal Express Checkout on the product page or cart (reduces steps to purchase)
- When targeting markets where PayPal is the dominant payment method (Germany, Netherlands, Brazil)
- When adding Venmo or Pay Later (installments) to appeal to younger shoppers
Core Instructions
Step 1: Create and configure your PayPal Business account
- Sign up for a PayPal Business account at paypal.com/business if you do not already have one
- Verify your business identity (required before you can receive payments)
- For development and testing: sign up at developer.paypal.com and create sandbox buyer/seller accounts
- Create an app at developer.paypal.com → My Apps → Create App to get your Client ID and Secret
Step 2: Install PayPal on your platform
Shopify
PayPal Express Checkout is built into Shopify and is enabled by default on most stores.
To verify or reconfigure:
- Go to Settings → Payments
- Under Payment providers, click PayPal or Activate PayPal
- If not already connected, click Activate and log in with your PayPal Business account to link it
- Choose between:
- PayPal Express Checkout: the classic checkout flow (recommended)
- PayPal Complete Payments: a newer integration that also supports Venmo and Pay Later
Enable Venmo and Pay Later:
- In your PayPal Business dashboard, go to Account Settings → Payment Preferences
- Enable Venmo and Pay Later — these appear automatically in the Shopify checkout once activated on your PayPal account
- To show a Pay Later banner on product pages: install the PayPal Pay Later Messaging app from the Shopify App Store

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.
