Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install payment-flow-testing

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes end-to-end tests that use Stripe test cards, handles the 3DS challenge in Playwright and simulates renewals with test clocks. It also checks webhook signatures and idempotent fulfilment.
