Does it include security features?

Yes, it prioritizes security by validating magic bytes instead of trusting extensions, sanitizing filenames, and enforcing strict upload size limits.

Which cloud providers are supported?

The skill is optimized for AWS S3 and Cloudflare R2, but provides patterns applicable to any S3-compatible storage solution.

How does this skill handle large file uploads?

It implements multipart uploads and presigned URLs to handle large files efficiently without overloading server resources or blocking the main execution thread.

Why use presigned URLs instead of server proxying?

Presigned URLs allow clients to upload directly to cloud storage, which reduces server bandwidth costs and improves application scalability.

Can it help with image optimization?

Yes, the skill includes guidance on handling image uploads and implementing optimization patterns to ensure fast loading times and reduced storage costs.
