Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

`convert_timestamp`	时间戳双向转换，时区统一北京时间(UTC+8)。传入 Unix 时间戳（整数秒或毫秒，自动识别；也接受数字字符串）返回 ISO 8601 北京时间字符串；传入日期/时间字符串（如 2026-09-05、2026-09-05 10:30:00、2026-09-05T10:30:00+08:00）返回 Unix 秒/毫秒时间戳；不传 value 返回当前时间的两种格式。
`convert_unit`	单位换算，支持四类：长度(m/km/cm/mm/mile/foot/inch，含毫米/厘米/英里/英尺/英寸)、重量(kg/g/mg/t/lb/oz，含克/磅/盎司)、温度(c/f/k，摄氏度/华氏度/开尔文，自动做偏移换算)、数据存储(B/KB/MB/GB/TB/PB，按1024二进制换算)。不支持的单位或跨类别换算（如米换算成千克）会返回清晰错误。
`format_json`	JSON 字符串处理。action 支持：format（美化缩进2格，中文不转义）、minify（压缩为单行去空白）、validate（仅校验合法性，非法时返回错误行号、列号、位置指针和上下文片段）。输入 data 必须是字符串。
`generate_qr`	生成二维码。默认 format='svg' 返回 SVG 矢量图字符串（纯标准库生成，可直接保存为 .svg 文件，AI agent 可直接写文件）；format='png' 时返回 PNG 图片的 base64 编码和 data URI（需服务器安装 Pillow，未安装会返回提示）。content 支持 URL、纯文本、WiFi 配置（如 WIFI:T:WPA;S:网络名;P:密码;;）等任意字符串，上限 2000 字节。CPU 密集，走线程池不阻塞事件循环。
`generate_uuid`	生成 UUID（通用唯一识别码）。支持 v4 随机 UUID（默认）和 v5 命名空间 UUID（SHA-1 确定性生成，需提供 namespace 和 name）。count 可一次生成多个（1~1000）。namespace 支持预定义名 dns/url/oid/x500 或完整 UUID 字符串。
`query_npm_version`	查询 npm 包的最新版本信息。输入 npm 包名（如 react、vue、express、@vue/cli），返回最新版本号 latest_version、该版本发布时间 published_at（UTC ISO 8601）、包描述 description、开源协议 license，以及主页/仓库地址等。数据源优先官方 registry.npmjs.org，失败自动兜底淘宝镜像 registry.npmmirror.com（国内更快）。包不存在返回明确的 404 提示。网络 I/O 走线程池不阻塞事件循环。
`resolve_dns`	DNS 域名解析（DoH，JSON API）。输入域名 name（如 baidu.com、www.qq.com）和记录类型 type（A 默认/AAAA/CNAME/MX/TXT），返回解析记录列表（每条含 name、type、ttl、data；MX 数据为优先级+邮件交换主机，TXT 为文本记录）。数据源优先阿里 DoH（dns.alidns.com，国内快），失败自动兜底 Cloudflare DoH。域名不存在返回 NXDOMAIN 提示；域名存在但无该类型记录时返回空列表并附说明。网络 I/O 走线程池不阻塞事件循环。
