## How to call it through Zero

```sh
zero fetch --capability opennext-r2-cache-cleanup-b6a25218
```

Example prompt: I have an OpenNext incremental cache on Cloudflare R2 and want to know which old build folders are safe to delete — here's my wrangler config, open-next config, next.config, the public build ID, and a listing of my cache folders. Which ones can I remove without touching the live build?

## When to prefer this

Use this endpoint when managing OpenNext incremental caches on Cloudflare R2 or Workers KV after Next.js redeployments, especially when unsure which folders belong to the live build versus old deploys. Ideal for DevOps automation agents handling post-deploy cache hygiene without risking deletion of active build assets.

## Known failure modes

- Missing or incomplete wrangler config causes incorrect cache root identification
- Mismatched build ID in public HTML vs folder listing leads to uncertain live build detection
- Unsupported cache folder naming convention (custom prefix vs deploymentId vs constant) may reduce accuracy
- Payment not settled results in 402 response before skill file is returned
- Malformed or incomplete folder listing may cause incomplete cleanup recommendations

## How this service works

OpenNext R2 Cache Cleanup for Next.js on Cloudflare — Decides which old build folders of an OpenNext incremental cache on Cloudflare (R2, or Workers KV) can be deleted, from a pasted setup (wrangler config, open-next config, next.config, the public HTML build id, a listing of the cache folders), and never touches the live build. It reads the cache root and the real folder name (a custom prefix, a deploymentId, a constant deploymentId, a no-build-id folder), finds the live build from the public …

## Output

Returns a SKILL.md file containing detailed guidance identifying which old build folders in the OpenNext incremental cache (R2 or Workers KV) can be safely deleted, which folder represents the live build, and instructions for safely performing the cleanup without disrupting the active deployment.
