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 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.

    content/skills/mugiwara-root-cause/references/four-phase-worked.md, line 17 $ curl -X POST /api/users -d '{"email":"[email protected]"}'

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/lib/patterns.sh, line 10 # .github/workflows/, webhooks?/, secret yaml, .tfvars, and .env variants

  • SECRETS_ENV_READ Note

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

    src/sign.ts, line 174 const secretKey = process.env.MUGIWARA_SIGN_KEY?.trim() || defaultKey('secret');

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

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.
