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 | $0.00026 | $0.02633 |
| Opus 5 | $0.00013 | $0.01316 |
| Sonnet 5 | $0.00005 | $0.00527 |
| Haiku 4.5 | $0.00003 | $0.00263 |
Grade A, and why
coupon-management 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.
How it starts

Coupon Management
Overview
Coupon systems let merchants create promotional codes with configurable rules: percentage or fixed-amount discounts, minimum order requirements, usage limits per coupon or per customer, and expiration dates. Every major e-commerce platform includes a built-in coupon system — you almost never need to build one from scratch. This skill walks you through setting up coupon management on each platform and explains when to reach for an app or plugin for advanced requirements like bulk unique codes or campaign tracking.
When to Use This Skill
- When adding promotional codes to a checkout flow for the first time
- When migrating from a simple discount field to a rule-based coupon engine
- When running marketing campaigns that require unique, single-use codes for each recipient
- When building an admin interface to create and monitor coupon performance
- When enforcing complex coupon rules such as product/category exclusions or customer segment restrictions
Core Instructions
Step 1: Determine the merchant's platform and the right tool
| Platform | Built-in Capability | When to Add an App/Plugin |
|---|---|---|
| Shopify | Shopify Discounts — supports percentage, fixed amount, free shipping, BOGO; usage limits, expiry, minimum purchase | When you need bulk unique codes (Shopify supports import), customer-group-specific coupons, or loyalty integration (Smile.io, LoyaltyLion) |
| WooCommerce | WooCommerce Coupons — built into core; percentage, fixed cart, fixed product, free shipping types | When you need bulk unique code generation: WooCommerce Smart Coupons plugin; advanced rules: YITH WooCommerce Dynamic Pricing & Discounts |
| BigCommerce | Coupon codes built in — percentage, fixed amount, free shipping, free product types | When you need B2B-specific codes or advanced restrictions; BigCommerce app marketplace has options like Coupon Manager Pro |
| Custom / Headless | Must build — see Custom section below | N/A — you are building the system |

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.
