Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- INSTALL_UNPINNED Low
Dependencies use a range or git URL with no lockfile.
requirements.txt, line 1
openai - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
templates/index.html, line 600
const res = await fetch(`${API_BASE}/sessions`); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
db/config.py, line 7
# Use POSTGRES_URL from .env - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
graph_builder.py, line 17
os.environ["LANGSMITH_API_KEY"] = os.getenv("LANGSMITH_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.
