Migrate Cloudflare Sandbox apps from stable @cloudflare/sandbox to @cloudflare/sandbox@next (SDK 1.0 preview). Use sandbox-next for apps already on the preview.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Migrate stable → Sandbox SDK 1.0 preview (`@next`) **Perform** the port. Follow the steps in order. Depth lives in docs—fetch the linked page when a step needs detail. Human guide: [Migrate](https://developers.cloudflare.com/sandbox/sdk/migrate/index.md) · [1.0 preview](https://developers.cloudflare.com/sandbox/index.md) **New projects** should start on `@next` (**`sandbox-next`**), not this skill. **Day-to-day stable work** → **`sandbox-stable`**. Deprecated-API cleanup **without** moving to `@next` → [2026 deprecation guide](https://developers.cloudflare.com/sandbox/sdk/migrate/index.md) first if needed.

How to install
mdr add fcakyon/claude-codex-settings/sandbox-migrate-to-next@sha256:50dcc3f3104745dcThe line at the top of this page pins the label git:20261028.6b4bcfa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
