What the reviewer found
Documentation for a repo-local scanner that finds references to skills and scripts that no longer exist: the <!-- orphan-ref-ignore-file --> comment is the scanner's own suppression directive being explained, and the .env, *.key, id_rsa and .npmrc list is the secret denylist of files it refuses to read. Read-only, repo-scoped, exits nonzero on findings.

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.
