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

SECRETS_PATH_DOTENV

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/appbacktest/SKILL.md, line 248 urlEnv: DATABASE_URL # only the NAME; the string goes in .env

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.
