What This Skill Does
Uploads files to Cloudflare R2 object storage using the wrangler CLI. Supports single-file and batch uploads via a shell script or direct wrangler commands. Uploaded files are served from a public R2 CDN domain.
Cloudflare R2 charges no egress fees, making it cheaper than S3 for files served frequently over the public internet.
When to use it
- Uploading article images to a CDN before publishing
- Batch-deploying static assets for a web project
- Hosting video files without incurring egress fees
- Replacing local file references with public R2 URLs
- Managing bucket contents by listing or deleting remote objects
