预签名URL上传、大文件分片上传、S3/R2/Supabase存储。
该技能用于实现高效、安全的文件上传功能，支持直接通过预签名URL上传到存储服务，避免代理服务器中转造成的性能瓶颈。对于大于5MB的文件，它会自动采用分片上传策略，将文件切分成多个部分并行上传，大幅提升传输速度。技能强调客户端与服务器双重验证：客户端可校验文件类型和大小，服务器会通过检查文件魔数（magic bytes）而非仅依赖扩展名来确保安全性。它还包含图片优化功能，在上传时自动调整尺寸（最大2048px）、转换为WebP格式并剥离EXIF信息。上传进度可通过 XMLHttpRequest 或 fetch API 配合 ReadableStream 实时追踪。支持的存储平台包括AWS S3、Cloudflare R2和Supabase Storage，并针对高安全场景提供病毒扫描能力。
