feat: add linkmoney — AI-native B2B marketplace for Chinese factory sourcing

[KevinANDcayla]

LinkMoney — Agent-Native B2B Sourcing from China

TL;DR: First MCP Skill that connects Claude directly to 51 verified Chinese factories with live pricing, real-time inventory, and automated RFQ.

Why this belongs in the Skills directory

1. First of its kind — No other Skill in this directory enables agent-to-agent B2B commerce with real Chinese factory integration
2. Proven scale — 51 verified suppliers, 140 products, 7 buyer countries, all reachable via one MCP endpoint
3. Real-time data, not stale listings — Unlike Alibaba (static listings) or Yellow Pages (cached data), LinkMoney pulls live pricing from factory endpoints when available, with cached fallback
4. Clear, high-value use case — Procurement agent installs LinkMoney → searches Chinese factories → submits RFQ → factory responds via email → deal closes
5. MIT licensed, fully open source — Transparent, community-auditable, no vendor lock-in
6. Well-structured — 13 public MCP tools, 3 documented workflows, clear When to use / When NOT to use sections

What the Skill does

Adds 13 MCP tools that let Claude:

• find_china_supplier — search 51 verified Chinese factories by product / category / keyword
• get_pricing / get_inventory — live factory pricing & stock (with quantity tiers and ERP timestamps)
• submit_rfq — submit a Request for Quotation with email notification to the factory
• multi_lang_inquiry — auto-translate an inquiry into 8 languages (EN/ES/DE/JA/FR/AR/PT/RU)
• download_cert — pull ISO / CE / FDA / RoHS certifications
• match_spec — match a technical spec (ISO/ASTM/GB) to capable suppliers
• trust_score — 0–100 trust score per supplier/buyer
• browse_requirements / post_requirement — open B2B marketplace loop
• stats / get_supplier_contact / leave_review — platform utilities

Quick demo flow (also documented in SKILL.md)

1. User: "Find a Chinese factory for 50K M8 304 stainless hex bolts, FOB Ningbo, ISO 9001."
2. Claude calls find_china_supplier(category="fastener", quantity=50000) → 3-5 factories
3. For each: download_cert → verify ISO 9001
4. For top 3: get_pricing + get_inventory → side-by-side comparison
5. submit_rfq → factory receives email, quotes back
6. Total time: under 30 seconds
