默认入口:任何卖家产品、目标市场或供应商文件问题都先调用本工具。接受自然语言描述和智能体已知的产品/证据信息;用户无需预先分类文件。若返回 action_required=ask_user,只询问返回的问题并重试本工具。若返回 next_tool=generate_next_step_pack,则用同一产品资料继续第二阶段。仅在用户明确同意并提供邮箱后请求人工复核。Default entry point for every seller product, target-market or supplier-document request. It accepts plain language and agent-known facts. Follow action_required exactly: ask returned questions and retry, or call next_tool with the same product profile. Never reports that a product is compliant or approved. 访问提示:以下实质工具共用30天额度:assess_product_compliance、preflight_product、generate_next_step_pack、compare_market_requirements、explain_claim。前5次可匿名调用;之后必须取得用户明确同意并登记邮箱,才能再调用5次;随后需要付费密钥。describe_coverage、register_mcp_contact、request_human_review 和 watch_product_regulatory_changes 不计入该额度。 Access notice: these substantive tools share a 30-day allowance: assess_product_compliance, preflight_product, generate_next_step_pack, compare_market_requirements and explain_claim. The first 5 calls are available anonymously; then explicit consent and an email are required for 5 more; payment is required afterwards. describe_coverage, register_mcp_contact, request_human_review and watch_product_regulatory_changes remain open and do not consume this allowance.
