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 | $0.00031 | $0.02300 |
| Opus 5 | $0.00015 | $0.01150 |
| Sonnet 5 | $0.00006 | $0.00460 |
| Haiku 4.5 | $0.00003 | $0.00230 |
Grade B, and why
marketplace-connectors 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.

Marketplace Connectors
Overview
Selling across Amazon, eBay, and Walmart Marketplace multiplies your sales channel reach but introduces operational complexity: each marketplace has its own product data model, listing requirements, order lifecycle, and inventory management API. This skill covers connecting your store to major marketplaces — using apps for managed platforms and direct API integration for custom storefronts.
When to Use This Skill
- When expanding sales channels beyond your own storefront to major marketplace platforms
- When building a multichannel commerce system that keeps inventory in sync across channels
- When automating order imports from marketplaces into your OMS or ERP
- When existing marketplace feeds are manual (spreadsheet uploads) and need automation
Core Instructions
Step 1: Determine your platform and recommended approach
| Platform | Recommended Approach | Key Apps |
|---|---|---|
| Shopify | Use a marketplace app — no custom code needed | Codisto ($39/month) for Amazon + eBay + Walmart; LitCommerce ($19/month) for multi-channel listing management |
| WooCommerce | Use a plugin for standard integrations | WooCommerce Amazon Fulfillment (free, amazon.com) for FBA; WP-Lister Pro for Amazon ($99) for full listing and order management |
| BigCommerce | Use App Marketplace connectors | Sellbrite ($79/month, marketplace.bigcommerce.com) syncs Amazon, eBay, Walmart, and Etsy; ChannelAdvisor for enterprise multi-channel |
| Custom / Headless | Direct API integration | Build using Amazon SP-API, eBay REST API, and Walmart Marketplace API; use a queue for order imports and inventory sync |
Step 2: Platform-specific marketplace setup
Shopify
Connect Amazon with Codisto:
- Install Codisto from the Shopify App Store ($39/month for Amazon + eBay)
- Connect your Amazon Seller Central account (US, UK, EU, AU supported)
- In Codisto, go to Listings → Amazon and click Link Products — it matches your Shopify products to existing ASINs or creates new listings
- Enable Inventory Sync to update Amazon quantities automatically when Shopify inventory changes
- Enable Order Import — Codisto imports Amazon orders as Shopify orders so you manage fulfillment from one place

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.
