Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_CAP_REACHED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
error-handling-patterns/scripts/retry.py, line 24
def fetch(): - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
error-handling-patterns/scripts/retry.py, line 24
def fetch(): - SECRETS_PATH_DOTENV Low
Mentions a .env file.

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.
