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

Rescanned at commit 4aca9ee1f7a7, unchanged since the check below.

SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    .gitignore, line 5 *.sqlite-wal

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    skills/crew/scripts/crew-mcp-driver.py, line 29 p = subprocess.Popen(

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.
