Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

INSTALL_LIFECYCLE_HOOK

Why this grade

  • INSTALL_LIFECYCLE_HOOK Medium

    A package install hook (preinstall, install, postinstall or prepare) runs a script.

    package.json, line 19 prepare

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
