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

Rescanned at commit acdbd80c68fa.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    tools/build.mjs, line 23 fs.rmSync(DIST_DIR, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    skills/accounting/reconcile-supplier-statement/INSTRUCTIONS.md, line 261 curl -sS -X POST "https://$SKU_TENANT.sku.io/api/purchase-invoices/supplier-payments" \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .env.example, line 1 # Copy to .env and fill in — used by the curl examples in each skill's INSTRUCTIONS.md.

  • SECRETS_ENV_READ Note

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

    tools/scan-secrets.mjs, line 41 const raw = process.env.SECRET_DENYLIST || '';

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.
