Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

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

Rescanned at commit 395d949baaae, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/migrate.mjs, line 940 fs.unlinkSync(absolutePath);

  • NETWORK_NO_FIXED_HOST Low

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

    skills/effective-interact/scripts/validate-interaction.mjs, line 729 let response = await fetch(endpoint, { method: "PUT" });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    harness/agent-hooks/safety-hook.mjs, line 28 /(^|[\s"'=\\/])\.env(?:$|[\s"'\\/]|\.((?!example\b|sample\b|template\b)[A-Za-z0-9_-]+))/i,

  • SECRETS_ENV_READ Note

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

    skills/mcp-builder/references/node_mcp_server.md, line 707 if (!process.env.EXAMPLE_API_KEY) {

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.
