Why this grade

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    justfile, line 12 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.

    skills/risk-graph/SKILL.md, line 320 const signer = privateKeyToAccount(process.env.EVM_PRIVATE_KEY as `0x${string}`);

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.
