Env Var Auditor vs Vibe-code Security Checker
The short answer
The Env Var Auditor reconciles your .env.example with the code and flags secret-looking values. The Security Checker reviews the code itself for auth gaps and injection. The auditor is a five-minute config check. The checker is a review of the change.
Env Var Auditor
Paste .env.example and the code that reads it. Get missing keys, unused keys, and names that look like live secrets.
- You paste
- Paste the example and the reads. Copy .env.example and the lines that read process.env or the equivalent. Redact any real secret first; leave the name. A placeholder is fine.
- You get
- The fix. Add FLY_REGION=local. Change the Stripe example to a sk_test_ placeholder. Do not print a real key.
- When to use it
- Use it when .env.example and the code drifted apart and you cannot tell which key the app will demand at boot.
- When to skip it
- Never paste your real .env with live values. Paste the example file and the code that reads it.

Vibe-code Security Checker
A review prompt for vibe-coded diffs. It hunts secrets, missing auth, injection, and insecure defaults, then names the fix.
- You paste
- Save the prompt where you write code. In Cursor, add the prompt as a project rule or paste it at the start of a review chat. In Claude or ChatGPT, save it as a project instruction. The rubric JSON can sit beside it.
- You get
- What it will not do. It will not hand you a working exploit. The sample key is fake. The output is the safer handler, not a payload.
- When to use it
- Use it before you deploy anything a model wrote that touches logins, secrets, user data, or a database.
- When to skip it
- It is not a penetration test and it refuses to write exploits. It names the risk and the fix.
