Grades are a hygiene check, not a security guarantee.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    skills/loopwork/scripts/progress.py, line 79 out = subprocess.check_output(["git", "-C", root(), "log", "--pretty=%H|%s"],

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/loopwork/scripts/guard_rules.py, line 72 SECRET_NAME = re.compile(r"(^|/)\.env(\.|$)|\.pem$|\.p12$|\.key$|(^|/)(secrets?|credentials?)\.", re.I)

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.
