Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    examples/openai/main.py, line 42 env_file=".env", env_file_encoding="utf-8", env_nested_delimiter="__"

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    examples/openai/README.md, line 10 curl -LsSf https://astral.sh/uv/install.sh | sh

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    examples/openai/main.py, line 48 client = AsyncOpenAI(api_key=os.environ.get("OPENAI_API_KEY"))

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

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.
