2. Production-Ready Stripe Cursor Rules (.cursorrules & .mdc)

Stripe integration rules for webhook signature verification and checkout session flows. Save this into .cursor/rules/stripe.mdc in your project repository.

// AI Instructions for Stripe
- Webhook routes MUST read the raw unparsed request body for stripe.webhooks.constructEvent.
- Always attach idempotency keys on retryable financial mutations.
- Use Stripe Checkout or Elements for PCI compliance; never touch raw credit card digits.
- Store customer ID and subscription status in your primary database; avoid synchronous round-trips on every page view.

3. Stripe Antigravity & Claude Code System Instructions

Add this concise instruction block to your workspace .gemini/rules or project system prompt.

// Context Anchor for Stripe
When writing code for Stripe, refer directly to the verified specifications at https://docs.stripe.com/llms.txt.
