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

Rescanned at commit bd4801a5c5fb, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    typescript-example/server/src/server.ts, line 29 const response = await fetch(url, { headers });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    typescript-example/client/index.ts, line 13 dotenv.config(); // load environment variables from .env

  • SECRETS_ENV_READ Note

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

    typescript-example/client/index.ts, line 15 const ANTHROPIC_API_KEY = process.env.ANTHROPIC_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.
