1-Click Fix Prompt for Cursor & Claude Code
Review my codebase for ".env Files Added to .gitignore Before Initial Commit" (SEC-009). Issue: AI scaffolding scripts create .env or .env.local files before initializing git, causing them to be tracked in history. Remediation required: Verify .gitignore contains .env, .env.local, .env.production, and *.pem before pushing commits. Please: 1. Locate any occurrences of this issue across my repository. 2. Refactor the code to follow production standards without breaking existing functionality. 3. Provide a clear command or step to test and verify the fix.
Why AI Assistants Write This Bug
AI scaffolding scripts create .env or .env.local files before initializing git, causing them to be tracked in history.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.

Common AI Code PatternVulnerable
// Vulnerable AI-generated pattern for: .env Files Added to .gitignore Before Initial Commit
// Leaking sensitive key in client-callable code
export const STRIPE_KEY = "sk_live_51OzRealProductionKey12345";
export async function checkout() {
// Client bundle exposes secret key to Chrome DevTools
}Launch-Ready Fix
// Production-ready fix for: .env Files Added to .gitignore Before Initial Commit
// Stored strictly in server-side environment variable
const stripeSecretKey = process.env.STRIPE_SECRET_KEY;
if (!stripeSecretKey) {
throw new Error("Missing STRIPE_SECRET_KEY in server environment");
}
// Invoked strictly inside server route or Server Action
export const stripe = new Stripe(stripeSecretKey);Remediation & Verification Checklist
