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

Rescanned at commit a34d3eb5bc37, unchanged since the check below.

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/auth_manager.py, line 260 os.remove(self.storage_path)

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    README.md, line 92 `curl -LsSf https://astral.sh/uv/install.sh | sh` (or `brew install uv`).

  • NETWORK_NO_FIXED_HOST Low

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

    src/auth_manager.py, line 186 response = requests.post(

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .env.example, line 2 # Copy to .env (or export in your shell) and fill in. Never commit .env.

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 92 `curl -LsSf https://astral.sh/uv/install.sh | sh` (or `brew install uv`).

  • SECRETS_ENV_READ Note

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

    src/config.py, line 11 WHOOP_CLIENT_SECRET = os.getenv("WHOOP_CLIENT_SECRET", "")

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

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    src/auth_manager.py, line 260

    os.remove(self.storage_path)

    src/whoop_install_skills.py, line 99

    shutil.rmtree(dest)

  • Install and update

    Concern

    dependencies are not pinned. README documents an installer that pipes a download into a shell.

    INSTALL_UNPINNED INSTALL_DOCUMENTED_INSTALLER

    README.md, line 92

    `curl -LsSf https://astral.sh/uv/install.sh | sh` (or `brew install uv`).

    requirements.txt, line 1

    mcp>=1.0.0

  • Network

    Concern

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

    NETWORK_NO_FIXED_HOST

    src/auth_manager.py, line 186

    response = requests.post(

    src/setup_direct_oauth.py, line 92

    resp = requests.post(

    src/whoop_install_skills.py, line 63

    with urllib.request.urlopen(req, timeout=10) as resp:

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    src/config.py, line 11

    WHOOP_CLIENT_SECRET = os.getenv("WHOOP_CLIENT_SECRET", "")

    .env.example, line 2

    # Copy to .env (or export in your shell) and fill in. Never commit .env.

    .gitignore, line 97

    # Environments

    CHANGELOG.md, line 61

    - `.env.example` rewritten. Previous file referenced `OAUTH_BASE_URL` pointing at the long-removed third-party OAuth proxy and didn't mention `WHOOP_CLIENT_ID` / `WHOOP_CLIENT_SECR
