What problem does it solve?

This Skill eliminates the manual hassle of managing student assignment (作品題) submissions, handling secure file uploads, original filename preservation, and teacher access without error-prone manual file management or duplicate submission records.

Core Features & Use Cases

• Secure S3 Upload Flow: Uses presigned URLs for direct student file uploads to S3, avoiding backend bottlenecks.
• Metadata Tracking: Stores original filenames separately from S3 keys to prevent filename loss from timestamp prefixes.
• Consolidated Grading View: Merges all student submission attempts into a single record to avoid duplicate entries and missing files.
• Use Case: For UMAC AI courses, this Skill lets students submit assignment files seamlessly, and teachers can easily download, review, and grade submissions without dealing with messy file naming or fragmented attempt records.
