gcs-upload

The skill is coherent with its purpose of managing GCS file uploads and generating signed URLs. However, there are notable security considerations around signed URL expiry strategy, handling of sensitive assets (certificates) via public-like URLs, and explicit least-privilege configuration for Google Cloud access. Recommend tightening access controls (shorter signed URL lifetimes or per-request tokens, strict IAM roles, server-side access checks), adding revocation/TTL mechanisms, and documenting explicit permission boundaries and logging for audit.
