janus

Janus, the Roman god of gates, has two faces looking in opposite directions — and so does this pipeline.

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 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.md, line 224 ax <url> # curl parity - never silent

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    plugins/janus/agents/lab-verify.md, line 195 - No credentials in code. Use .env files (gitignored).

  • PERMISSION_SHELL_DECLARED Note

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

    plugins/janus/skills/deck/scripts/svgtools.py, line 106 subprocess.run(cmd, check=True, capture_output=True)

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.
