README

assets-to-r2

A Claude Code skill (plus a standalone Bun CLI) that moves heavy binary assets out of a git repository onto Cloudflare R2 behind `cdn.nuasite.com`, and rewrites every reference to absolute CDN URLs.

Built for the recurring problem where a site repo accumulates gigabytes of committed article photos, uploaded PDFs and crawled media — typically after a site rebuild — and every clone pays for it.

Why the rewrite is mandatory

The nuasite `` component (`@nuasite/components`) builds Cloudflare transform URLs by splicing the origin of `src` into the prefix:

`src`	emitted
`/assets/a.jpg`	`/cdn-cgi/image/…/assets/a.jpg` — against the site's own host
`https://cdn.nuasite.com/assets/x/a.jpg`	`https://cdn.nuasite.com/cdn-cgi/image/…/assets/x/a.jpg`

Same-zone is structural — the component never emits a cross-origin form. So once an asset lives on R2, a root-relative reference asks the site's zone to transform a file it no longer hosts. See `reference/nuasite-image.md`.

Install

Clone into your Claude skills directory; the checkout *is* the skill:

git clone git@github.com:contember/assets-to-r2.git ~/.claude/skills/assets-to-r2

Claude picks it up automatically. Requires Bun — the CLI has no dependencies (it uses `Bun.S3Client`).

Use

Ask Claude: *"presuň assety z tohohle repa na CDN"*. Or drive the CLI directly from the target repo's root:

A2R=~/.claude/skills/assets-to-r2/scripts/a2r.ts

bun $A2R preflight --slug my-project        # prove creds + that the zone fronts the bucket
bun $A2R inventory --slug my-project        # classify assets → .a2r/plan.json
bun $A2R mark move --class uncertain        # adjust the plan
bun $A2R upload --dry-run                   # then without --dry-run
bun $A2R rewrite                            # dry-run; then --apply
bun $A2R verify                             # CDN reachability + a real cdn-cgi transform
bun $A2R prune --apply                      # del
