Grades are a hygiene check, not a security guarantee.

ai

Open-source tools from DIDWW for building AI voice agents on real phone numbers: agent skills, documentation and the scripts that keep them tested and published.

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 SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/didww-connect/scripts/monitor.py, line 57 with urllib.request.urlopen(req, timeout=30) as r:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 5 .env

  • PERMISSION_SHELL_DECLARED Note

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

    scripts/test_installers.py, line 17 r = subprocess.run(["node", os.path.join(skill_dir, "bin", "install.js"), *args],

  • SECRETS_ENV_READ Note

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

    skills/didww-connect/scripts/monitor.py, line 19 KEY = os.environ.get("DIDWW_API_KEY", "")

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

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    scripts/test_installers.py, line 17

    r = subprocess.run(["node", os.path.join(skill_dir, "bin", "install.js"), *args],

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.
