What the reviewer found
UserPromptSubmit runs the third-party Entire CLI (`entire hooks claude-code user-prompt-submit`), which checkpoints agent session transcripts into git. The CLI is not in the packet, so its handling of the prompt is unreviewed.

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.
