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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    benchmarks/credibility_benchmark.py, line 224 subprocess.run(["git", "init", "-q"], cwd=root, capture_output=True, check=False)

  • NETWORK_NO_FIXED_HOST Low

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

    sdk/node/src/index.js, line 200 const response = await this.fetch(this.endpoint + HTTP_PATHS[operation], {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/buildanchor/build_truth/adapters/python.py, line 58 for environment in ("venv", ".venv", "env", ".env"):

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 246 curl -fsSL https://raw.githubusercontent.com/tensilestream/buildanchor/main/scripts/install.sh | bash

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.
