Graded by PlugVetRubric v2

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

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    cmd/keyward/cli_test.go, line 35 if err := os.WriteFile(filepath.Join(proj, ".env"), []byte("TOKEN=supersecret\n"), 0o600); err != nil {

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    internal/approval/dialog_darwin.go, line 18 out, err := exec.Command("osascript", "-e", script).Output()

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.
