## Tools (11)

- `bazi_chart`: 八字排盘 from birth date and hour: four pillars (年月日时柱), five-element counts, 纳音, zodiac. Uses true solar-term boundaries.
- `china_reachability`: Fetch a URL from a real mainland-China network egress and report HTTP status, latency and China DNS resolution. Answers "is my site/API usable from China?" with a measurement instead of a guess — you cannot get this from a VPS abroad.
- `cn_holiday`: Is a date a Chinese public holiday, weekend, or 调休 make-up workday? Plus the next holiday.
- `huangli`: Chinese almanac for a date: 宜 (auspicious activities), 忌 (avoid), 冲煞, 彭祖百忌. date omitted = today.
- `id_card_check`: 中国大陆身份证号校验:check digit validity, birth date, age, gender, region code. id = 18-digit ID number.
- `lunar_calendar`: Chinese lunar calendar for any date: 农历、干支纪年、生肖、节气、节日、星座。date omitted = today.
- `phone_info`: 中国大陆手机号识别:validity, carrier (移动/联通/电信/虚拟运营商), formatted forms. phone = 11-digit number.
- `pick_lucky_days`: Find auspicious days in a month for an event: 结婚/领证/搬家/开业/装修/出行/签约/订婚/安床/安葬 or any 黄历宜 term.
- `pinyin_convert`: Convert Chinese text to pinyin: with or without tones, first letters only, or as a slug. text = Chinese text.
- `reachability_report`: 一批 URL 的中国大陆可达性体检 → PDF 报告:逐个的可达结论、延迟、HTTP 状态与大陆 DNS 解析到的 IP。探测从真实的中国移动骨干网节点发出,不是境外 VPS 推断。入参 urls(数组或逗号分隔,最多 20 个)。自证不通过不计费。
- `what_can_you_do`: Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-to-run example calls — instead of reading the whole catalogue and guessing. Also returns multi-step recipes when a task needs several tools chained (invoices to a ledger, a bank statement reconciled, a messy CSV turned into a deliverable). Deterministic and free: it calls no model, costs nothing, and never runs out of quota. Call this FIRST when you are not sure what this server offers.
