Graded by PlugVetRubric v2

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

Rescanned at commit 0d0b647718a6, unchanged since the check below.

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    bin/hook-state.js, line 36 fs.unlinkSync(markerPath(sessionId));

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/load-env.js, line 14 const CONFIG_ENV_PATH = path.join(os.homedir(), ".conventions-mcp", ".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.
