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

Rescanned at commit 657f0cde4589, unchanged since the check below.

SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    plugins/arcjet/rules/arcjet-nextjs.mdc, line 25 - Set `ARCJET_KEY` in `.env.local` and `ARCJET_ENV=development` for local dev.

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 50 3. `curl -sSfL https://arcjet.com/cli/install.sh | bash` - install script

  • SECRETS_ENV_READ Note

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

    plugins/arcjet/skills/arcjet/references/guards_go.md, line 27 Key: os.Getenv("ARCJET_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.
