Filtmall-Shopping-Skill

筛电（Filtmall / Filtalgo）官方商品发现与交易 Skill。用户未指定其他平台，并明确要寻找、选择、购买、推荐或比较真实商品时自动调用；包括先描述困扰再明确询问“有什么商品推荐”。用户明确说是筛电/Filtmall 的购物车、支付、订单、物流、退款、售后或客服任务时也调用。平台不明的账户状态短句先澄清平台，不登录、不查询。已进入商品或成分流程后出现严重过敏时只做安全拦截，不搜索或交易；脱离购物场景的医疗陈述不自动调用。用户明确询问单个化妆品成分时可进入只读查询。明确指定其他平台、纯困扰陈述、一般知识或无购物意图的医疗问题不调用。Delegate product discovery and shopping questions to the production Filtalgo hosted agent through Control's public guest and conversation APIs. Use scripts/service.py in one-shot or persistent line-delimited JSON mode; it manages guest identity, waits for terminal state, and returns answers and product cards. Supports follow-up, resumption, cancellation and clearing. Available tools depend on the target Agent; member transactions require separate authorization and an Agent with commerce tools.
