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 | $0.00025 | $0.02571 |
| Opus 5.5 | $0.00010 | $0.01028 |
| Sonnet 5.5 | $0.00005 | $0.00514 |
| Haiku 4.5 | $0.00003 | $0.00257 |
Grade A, and why
inventory-tracking 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 2mo 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.

Inventory Tracking
Overview
Real-time inventory tracking prevents overselling by reserving stock when customers add items to their cart and decrementing it on order fulfillment. Every major e-commerce platform has this built in. Platform-native inventory tracking is almost always the right starting point — only build custom inventory logic if you have requirements that platforms cannot meet (complex multi-warehouse routing, custom reservation windows, or external WMS integration).
When to Use This Skill
- When overselling is occurring and orders are being placed for out-of-stock items
- When implementing multi-warehouse inventory with per-location stock levels
- When building backorder or pre-order functionality for out-of-stock products
- When a flash sale or product launch will create high-concurrency checkout attempts for limited-stock items
Core Instructions
Step 1: Determine platform and enable inventory tracking
| Platform | Built-in Inventory | Recommended Extension |
|---|---|---|
| Shopify | Native per-variant inventory tracking with location support | Stocky (free, by Shopify) for purchase orders and demand forecasting |
| WooCommerce | Native stock management with backorder support | ATUM Inventory Management for advanced multi-warehouse and supplier POs |
| BigCommerce | Native per-SKU inventory tracking with low-stock alerts | Multi-Location Inventory app for warehouse routing |
| Custom / Headless | Build atomic reservation with optimistic locking | Required for custom platforms without native inventory management |
Step 2: Platform-specific setup
Shopify
Shopify tracks inventory per variant, per location, natively.
Enable inventory tracking:
- Go to Admin → Products → [Product] → [Variant]
- Under Inventory, check Track quantity
- Enter your quantity per location
- For "Continue selling when out of stock" — only check this if you allow backorders for this product

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.
