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

Rescanned at commit 97bcd4ed21c0, 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.

    src/api.ts, line 289 response = await fetch(url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/index.ts, line 35 registerWriteEnv(server); // writes the cnk_ key into a project .env server-side - key never enters context

  • SECRETS_ENV_READ Note

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

    skills/clocknext-onboarding/references/code-metering.md, line 32 export const meteringEnabled = Boolean(process.env.CLOCKNEXT_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.

    so the code you generated (which reads `process.env.CLOCKNEXT_API_KEY`) can run; the alternative is the user
