Is PreToolUse safe to install?

Yes — PreToolUse is safe to install, on this review. Fable 5.1 read every file PreToolUse ships from apache/superset on 7 September 2026 and found nothing that acts against the person installing it; the static scan of its 26 rules grades it A.

Reviewed by Fable 5.1 on 7 September 2026 · a grade is what a scan and a reading found, not a guarantee · how this works

What the reviewer found

PreToolUse on Bash pipes the tool input through jq and, only when the command starts with 'git commit', runs 'pre-commit run' in the project directory with '|| true' so it never blocks. Local lint run using the repository's own pre-commit config; nothing leaves the machine.

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.
