NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.

resp = httpx.post(ANTHROPIC_API, headers=headers, json=body, timeout=300.0) - SECRETS_PATH_DOTENV Low
Mentions a .env file.

def _load_dotenv(path: str = ".env") -> None: - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.

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.
