Grades are a hygiene check, not a security guarantee.

Synapse GEO Growth Layer

The GEO check every vibe coder runs before they launch.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    apps/web/scripts/seed.mjs, line 56 const upsertRes = await fetch(`${url}/rest/v1/sites?on_conflict=slug`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    apps/web/scripts/diag.mjs, line 5 const raw = await fs.readFile(".env.local", "utf8");

  • SECRETS_ENV_READ Note

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

    apps/web/src/app/api/sites/route.ts, line 19 process.env.SYNAPSE_ADMIN_KEY ?? process.env.SYNAPSE_DEPLOY_API_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.
