Which cloud providers are covered?

While focusing on S3-compatible storage like Amazon S3 and Cloudflare R2, the principles can be applied to most major cloud providers.

Can it help with large file transfers?

Absolutely. The skill includes patterns for multipart uploads to ensure large files are handled reliably without timing out or blocking.

How does it handle file security?

It implements strict magic byte validation to verify file types and enforces filename sanitization to prevent path traversal attacks.

Does this skill support direct-to-cloud uploads?

Yes, it prioritizes presigned URLs to allow clients to upload directly to S3 or R2, reducing server load and improving performance.

Why should I use presigned URLs instead of server proxying?

Presigned URLs are more secure and efficient as they allow temporary, authorized access for uploads without proxying heavy data through your application server, saving bandwidth and CPU.
