Grades are a hygiene check, not a security guarantee.

Claude Code, Skill

Claude Sonar

Audit a local Windows proxy and system setup, with limited macOS/Linux environment collection, for routing, DNS, IPv6, IP reputation, timezone, language, and documented Claude Code privacy controls.

Compatibility: Not stated.

Grade B

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

Graded by PlugVetRubric v2

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.

    claude_sonar/serve.py, line 246 # A client that aborts mid-request (curl pipe closed, tab closed) is

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    claude_sonar/serve.py, line 246 # A client that aborts mid-request (curl pipe closed, tab closed) is

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    claude_sonar/reposcan/stack.py, line 69 "venv", ".venv", "env", ".env", "site-packages",

  • PERMISSION_SHELL_DECLARED Note

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

    claude_sonar/analyze.py, line 63 result = subprocess.run(command, capture_output=True, timeout=timeout)

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

    requests shell access. The manifest names this permission.

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.ipify.org. The description does not name that host. can reach ipwho.is. The description does not name that host.
