Why does this skill prefer presigned URLs?

Presigned URLs allow clients to upload files directly to cloud storage, which significantly reduces server load, prevents proxying bottlenecks, and enhances overall performance.

Does it handle large file uploads?

Yes, it includes specialized logic for multipart uploads, ensuring that large files can be uploaded in chunks without blocking the main application thread.

How does it improve file upload security?

The skill enforces critical security measures such as checking magic bytes to verify file types, sanitizing filenames to prevent path traversal, and implementing strict size limits.

Can it assist with image optimization?

Yes, it provides implementation patterns for image handling and optimization to ensure storage is used efficiently and assets are served quickly.

What cloud providers does this skill support?

It specifically specializes in AWS S3 and Cloudflare R2, though the principles applied can be adapted for most S3-compatible storage providers.
