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.

    skills/telegram-serverless/references/patterns.md, line 156 const res = await fetch(`${baseUrl}/chat/completions`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 9 .env

  • SECRETS_ENV_READ Note

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

    skills/telegram-serverless/scripts/lint-project.mjs, line 183 if (/\bprocess\.env\b/.test(line)) err(`${rel}:${n}`, 'process.env is not available at runtime; there is no documented secrets store.');

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.
