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

Rescanned at commit 75c6837e5dd1, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/edge-plc-app-deployment/SKILL.md, line 251 python3 -c "import socket; print(socket.create_connection(('HOST', PORT), 5))"

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 4 .env

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.
