Write Gherkin/Cucumber `.feature` files that run as Playwright end-to-end tests for any web app using the steps shipped by `@kumahq/gherkin-web/playwright`. Use whenever the user asks to write or extend an e2e test, add a feature file, test a user flow, verify a UI state, assert an outgoing API request, or cover an edge/empty state โ even if they don't say the words 'Gherkin' or 'Playwright'.
Write HTTP API mock files for the kuma-gui mock server under `packages/kuma-http-api/mocks/`. Use whenever the user asks to add or update a mock endpoint, mock a new list/item resource, randomise mock response data with faker, register a new route in `fs.ts`, or extend the `FakeKuma` helpers โ even if they don't say the word 'mock'.
