Secure your Stripe webhook against fake payments
Make sure nobody can fake a payment or get double credit through your Stripe webhook. Finds your handlers and checks signature verification, raw body, signing secret in env, once-only processing, 400 on bad signatures, and that access comes from the webhook, not the success page, then proposes diffs. Reads your code only; never calls Stripe.

How this works
- It is a skill: written instructions Claude reads when your request matches what the skill is for. You do not call it by name; just ask for the task.
- While it works, it reads and changes files in the places it lists, nowhere else.
- It runs these commands on your computer: node scripts/webhook-scan.mjs.
- Nothing runs until you choose to use it, and you can remove it any time.
What it can access
What this kit says it will touch, the same list you see before you add it. These are its Permissions: What a kit is allowed to touch on your computer or accounts, such as reading a folder or using the internet. You see them before you add it.. In Claude Code they become rules, so Claude stops anything not on the list.
Command
Runs the command: node scripts/webhook-scan.mjs (with any arguments, without asking)
