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

Rescanned at commit 761479eac213, unchanged since the check below.

INSTALL_UNPINNED SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    README.md, line 139 **"MCP server not found"** - Install `uv`: `curl -LsSf https://astral.sh/uv/install.sh | sh`

  • SECRETS_PATH_UNCONFIRMED Low

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

    .gitignore, line 6 venv/

  • PERMISSION_SHELL_DECLARED Note

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

    plugins/aws-cost-saver/skills/reviewing-findings/scripts/review_findings.py, line 61 result = subprocess.run(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 139 **"MCP server not found"** - Install `uv`: `curl -LsSf https://astral.sh/uv/install.sh | sh`

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.
