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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/check-submission-readiness.mjs, line 85 const response = await fetch(url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/verify-mcpb.mjs, line 47 for (const prefix of ["src/", "tests/", "scripts/", "mcpb/", ".env"]) {

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    src/reviewers/health.ts, line 281 agy: "Install the Antigravity CLI (agy): curl -fsSL https://antigravity.google/cli/install.sh | bash - then run `agy` once and sign in",

  • SECRETS_ENV_READ Note

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

    src/reviewers/common.ts, line 301 const apiKey = process.env["OPENROUTER_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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command call was found in the code. This check does not read permissions an entry declares. A permission line to write or edit files was found in this repository, and it may apply to this entry.

  • Install and update

    Note

    The docs document an installer that pipes a download into a shell.
