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.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    bin/install-laya-serve.ps1, line 43 rem Live state: curl http://127.0.0.1:8770/api/health

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    bin/install-laya-serve.ps1, line 43 rem Live state: curl http://127.0.0.1:8770/api/health

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    upstream/jev/references/pitfalls.md, line 139 auto-load `.env`. Restart/reload the host as needed; a shell export may not reach an

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    bin/skillopt-mcp-probe.py, line 31 p = subprocess.Popen(

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.
