What the reviewer found
Stop runs '.claude/skills/impeccable/scripts/impeccable hook' only if that file exists; the file is a skill-installed binary or script that is not in the packet, so its behaviour is unreviewed. It is described as a 'Design deep pass' with a 30 second timeout.
unconditional— runs without any action from the userunreviewed-script— runs a script that could not be read

What the static scan said
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.
