    examples/minimal/lib/auth.ts, line 30 // Hardcoded fallback: allows `next build` with no `.env` (Better Auth requires a

  • SECRETS_ENV_READ Note

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

    SKILL.md, line 69 privateKey: process.env.FIREBASE_PRIVATE_KEY!.replace(/\\n/g, "\n"),

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.
