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 | $0.02585 |
| Opus 5 | $0.00014 | $0.01293 |
| Sonnet 5 | $0.00006 | $0.00517 |
| Haiku 4.5 | $0.00003 | $0.00259 |
Grade A, and why
multi-channel-selling 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 12d 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.

Multi-Channel Selling
Overview
Multi-channel selling lets you list products on your own website, Amazon, eBay, Walmart, and wholesale portals simultaneously — with inventory synchronized in real time so you never oversell. The critical rule: one inventory pool, updated immediately when any channel sells or restocks. Purpose-built channel management tools (Linnworks, Sellbrite, Skubana/Extensiv) make this manageable without custom integration work.
When to Use This Skill
- When expanding beyond your own website to sell on Amazon, eBay, or Walmart Marketplace
- When running both a retail DTC site and a wholesale B2B portal from the same inventory pool
- When selling the same products under different brand names or content across channels
- When overselling on one channel because inventory is not shared in real time
- When building a channel management platform that lets brands manage all their sales channels in one place
Core Instructions
Step 1: Determine your platform and choose the right channel management tool
| Platform | Recommended Tool | Why |
|---|---|---|
| Shopify | Shopify's native Sales Channels + Sellbrite or Linnworks for external marketplaces | Shopify has built-in Facebook, Instagram, Google, and TikTok channels; Sellbrite adds Amazon/eBay/Walmart with inventory sync |
| WooCommerce | WP-Lister Pro (Amazon + eBay) or Linnworks | WP-Lister Pro lists products from WooCommerce directly to Amazon/eBay and syncs orders back |
| BigCommerce | BigCommerce Channels + Codisto (for Amazon/eBay) | BigCommerce has a native Channel Manager; Codisto extends it to Amazon, eBay, and Walmart with real-time sync |
| Any Platform | Linnworks or Skubana (Extensiv) as a central OMS | These tools sit above all channels and act as the single source of inventory truth for high-volume multi-channel operations |
Step 2: Set up your primary store as the inventory master
Before connecting any channels, ensure your primary store has:
- Accurate stock levels for all SKUs
- Product dimensions and weights entered (required for marketplace listings)
- HS codes if selling internationally
- UPC/GTIN barcodes on all products (required for Amazon and Walmart listings)

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.
