Which cloud providers are supported?

The skill focuses on AWS S3, Cloudflare R2, and other S3-compatible storage solutions.

Can it help with image optimization?

Yes, it includes guidance on implementing image optimization strategies during the upload workflow to save storage and bandwidth.

Why does it prefer presigned URLs?

Presigned URLs allow clients to upload directly to storage, which reduces server load and prevents your backend from becoming a bottleneck.

How does this skill improve file upload security?

It enforces magic byte verification to prevent file spoofing and provides patterns for filename sanitization to block path traversal attacks.

Does it support large file uploads?

Yes, it specializes in multipart uploads and non-blocking patterns to handle large datasets without impacting application performance.
