Grades are a hygiene check, not a security guarantee.

Claude Code, Plugin

mlflow

Skills for tracing, evaluating, and improving AI agents with MLflow.

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.

Rescanned at commit 3b0d56a394c3.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    querying-mlflow-metrics/scripts/fetch_metrics.py, line 147 with urllib.request.urlopen(req, timeout=30) as response:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    agent-evaluation/SKILL.md, line 128 **If BOTH are already set, skip Steps 1-2 entirely.** The environment is pre-configured. Do NOT run `setup_mlflow.py`, do NOT create a `.env` file, do NOT override these values. Go

  • PERMISSION_SHELL_DECLARED Note

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

    agent-evaluation/scripts/create_dataset_template.py, line 110 result = subprocess.run(["python", "-c", code], capture_output=True, text=True, check=True)

  • SECRETS_ENV_READ Note

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

    agent-evaluation/scripts/validate_auth.py, line 32 token = os.getenv("DATABRICKS_TOKEN")

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
