What problem does it solve? Choosing open-source building blocks for a cross-border e-commerce agent system is slow and risky: projects may be abandoned, carry restrictive licenses, or lack APIs. This Skill provides a pre-verified capability map of GitHub projects across 36 business modules, with stars, licenses, maintenance status, and A/B/C/D integration grades, so you can select components without repeating costly research. ## Core Features & Use Cases - 36-Module Capability Map: Covers ERP, OMS, inventory, procurement, CRM, customer service, email, marketing, SEO, ads, analytics, and channel connectors, each with recommended projects, stars, license, tech stack, and a one-line rationale. - License Risk Reference: A lookup table explaining MIT/Apache/BSD/LGPL/GPL/AGPL/Elastic License implications for self-hosting versus SaaS, plus a verified list of unusable or high-risk projects. - Search Discipline Rules: Star thresholds, maintenance checks, and candidate limits that prevent agents from wasting tokens on low-quality GitHub projects. - Use Case: When asked which open-source project to use for inventory management, consult the map and recommend InvenTree (MIT, official MCP) instead of re-running a full GitHub investigation. ## Quick Start Ask the agent to recommend an open-source project for a specific cross-border e-commerce module such as order management or price monitoring using the capability map.
