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

Rescanned at commit 2513e6cec053, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    main.py, line 153 os.remove(temp_file_path)

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    llms-full.txt, line 5438 const response = await fetch(url, { headers });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    llms-full.txt, line 2751 * Always use absolute paths in your configuration and `.env` files to ensure reliable operation

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    llms-full.txt, line 5037 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.

    llms-full.txt, line 1 # Example Clients

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    main.py, line 153

    os.remove(temp_file_path)

  • Install and update

    Note

    INSTALL_DOCUMENTED_INSTALLER

    llms-full.txt, line 5037

    curl -LsSf https://astral.sh/uv/install.sh | sh

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    llms-full.txt, line 5438

    const response = await fetch(url, { headers });

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_PATH_DOTENV

    llms-full.txt, line 2751

    * Always use absolute paths in your configuration and `.env` files to ensure reliable operation

    llms-full.txt, line 3416

    Create a `.env` file to store it:

    # Create .env file

    Show more

    llms-full.txt, line 3420

    touch .env

    llms-full.txt, line 3423

    Add your key to the `.env` file:

    llms-full.txt, line 3429
