Most apps built with AI coding tools ship with zero security review, no error handling, and obvious vulnerabilities. The Neuron published 10 copy-paste prompts that vibe coders should run before launching anything — catching the failures that will take down your app, expose user data, or empty your API budget.
The 10 Prompts
1. Security Audit
"Review this codebase for security vulnerabilities: SQL injection, XSS, CSRF, exposed API keys, insecure authentication, and missing input validation. List every vulnerability with file, line number, and fix."
Most vibe-coded apps have at least 3 critical vulnerabilities because the AI prioritized functionality over security.
2. Error Handling Check
"Find every function that can throw an error but has no try/catch or error handling. List each one and show what happens when it fails."
3. API Key Exposure
"Search this entire codebase for hardcoded API keys, secrets, tokens, passwords, and credentials. Check .env files, config files, and inline code. Are any exposed in client-side code?"
4. Rate Limiting
"Does this app have rate limiting on any endpoint? If not, what happens if someone sends 10,000 requests per second? Show me the endpoints most vulnerable to abuse."
5. Data Validation
"Find every user input field and trace it through the code. Is it validated? Sanitized? What happens if someone enters malicious input, an empty string, or a 10MB string?"
6. Authentication Gaps
"List every endpoint/route in this app. Which ones require authentication? Which ones don't but should? Can any authenticated endpoint be accessed by the wrong user role?"
7. Database Safety
"Review all database queries. Are any built with string concatenation instead of parameterized queries? Is there any risk of data leakage between users?"
8. Dependency Audit
"List all dependencies in this project with their versions. Flag any with known CVEs, any that are unmaintained (no updates in 12+ months), and any that seem unnecessary."
9. Cost Explosion Check
"If this app gets 10,000 users tomorrow, what breaks? Calculate the estimated monthly cost for API calls, database queries, storage, and compute at that scale."
10. Failure Mode Analysis
"What happens when: the database goes down, an external API returns an error, a user uploads a 500MB file, two users edit the same resource simultaneously, the payment webhook fires twice? Show me each failure path."
Why This Matters Now
Vibe coding’s speed advantage becomes a liability without quality gates. The Claude Code source leak showed how quickly vulnerabilities in code get exploited. AI-generated code isn’t inherently less secure than human code, but it’s built faster — which means security gaps accumulate faster too.
Running these 10 prompts takes about 30 minutes with any modern AI coding tool. That’s 30 minutes between launching confidently and launching a breach report.
