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 | $0.02628 |
| Opus 5.5 | $0.00010 | $0.01051 |
| Sonnet 5.5 | $0.00005 | $0.00526 |
| Haiku 4.5 | $0.00003 | $0.00263 |
Grade A, and why
marketplace-building 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.

Marketplace Building
Overview
A multi-vendor marketplace lets independent sellers list products on your platform, collects payment from buyers, deducts your commission, and pays out the remainder to sellers. The key components are: seller onboarding with KYC verification, product listing management per seller, commission calculation, and automated payouts. For Shopify and WooCommerce merchants, purpose-built marketplace apps handle most of this — custom development is needed primarily for highly specific commission structures or white-label marketplace platforms.
When to Use This Skill
- When building a platform where third-party sellers list and sell their own products (not your inventory)
- When you need the platform to collect payment from buyers and distribute funds to sellers minus a commission
- When sellers need their own dashboard to manage listings, view orders, and track earnings
- When complying with KYC (Know Your Customer) requirements for seller identity verification
- When designing the commission structure (percentage, tiered, category-based) and payout schedule
Core Instructions
Step 1: Determine your platform and choose the right marketplace tool
| Platform | Recommended Tool | Why |
|---|---|---|
| Shopify | Multi Vendor Marketplace by Webkul or BOLD Multi-Vendor | Webkul's app adds seller accounts, product management, commission rules, and a seller dashboard to Shopify without replacing the storefront |
| WooCommerce | Dokan Multi-Vendor (most popular, 60K+ installs) or WC Vendors | Dokan is purpose-built for WooCommerce marketplaces with seller onboarding, commission management, payout requests, and a seller dashboard |
| BigCommerce | Multi Vendor Marketplace by Webkul (BigCommerce version) | Webkul has a BigCommerce version of their marketplace app |
| Custom / Headless | Build seller accounts + Stripe Connect for KYC and payouts | Stripe Connect handles KYC, bank account collection, and 1099-K tax forms — use it for any custom marketplace |

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.
