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

Graded by PlugVetRubric v2

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

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.

    .agents/skills/expect-fail/mocking.md, line 46 fetchProfile: (id) => http.get(`/profiles/${id}`),

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    SECURITY.md, line 15 - **No secrets in source** - the framework never stores credentials, API keys, or tokens. Secrets belong in environment variables or a gitignored `.env`, never in tracked files.

  • SECRETS_ENV_READ Note

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

    .agents/skills/expect-fail/mocking.md, line 34 const gateway = new PaymentGateway(process.env.PAYMENT_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.
