What the reviewer found
Codebase-refactoring skill for Cloudflare Workers. The curl piped to python3 reads a localhost dev-server JSON response to check a field, the rm -rf clears the project's local .wrangler/state/v3/d1/ cache, and every network call is to localhost — nothing leaves the machine.

The 26-rule scan found nothing in this file; the review read it anyway.
How this review was made
Fable 5.1 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
