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

Rescanned at commit 6f873bac8711, unchanged since the check below.

PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • PERMISSION_SHELL_DECLARED Note

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

    src/upnote_lens/writer.py, line 42 subprocess.run(["open", url], check=True)

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 61 (`brew install uv`, or `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.
