bkend-storage

The skill's footprint is coherent with a storage backend capability focusing on presigned URLs, multipart uploads, and metadata management. There are no evident credential-forwarding, unverifiable binaries, or hidden data-exfiltration mechanisms in the provided material. The security posture hinges on proper server-side authentication/authorization, secure handling of presigned URLs, and robust access controls, which are not fully detailed here but are reasonable expectations for the described endpoints. Overall, the skill appears benign and proportionate to its stated purpose, with moderate need for explicit auth and TLS considerations in implementation.
