Why this grade

  • PERMISSION_SHELL_DECLARED Note

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

    src/cloud_music_mcp/auth.py, line 85 subprocess.run(["open", qr_path])

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 66 curl -LsSf https://astral.sh/uv/install.sh | sh

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    uv.lock, line 1 version = 1

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.
