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

Rescanned at commit f2f920bd5376, unchanged since the check below.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/tools/handlers/grok.ts, line 112 .describe('Repeatable deny rules in `ToolPrefix(glob)` form, e.g. `Read(.env)`.'),

  • PERMISSION_SHELL_DECLARED Note

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

    src/grok/exec.ts, line 2 * Imperative shell around `child_process.spawn` for a headless grok run.

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.
