  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Setup

On first use, read setup.md for integration guidelines.

When to Use

User needs E2E tests, component tests, or API tests with Cypress. Agent writes tests, debugs flaky specs, configures CI/CD, and creates custom commands.

Architecture

Project tests live in the standard Cypress structure: cypress/ โ”œโ”€โ”€ e2e/ # E2E test specs โ”œโ”€โ”€ component/ # Component tests (if enabled) โ”œโ”€โ”€ fixtures/ # Test data JSON files โ”œโ”€โ”€ support/ โ”‚ โ”œโ”€โ”€ commands.ts # Custom commands โ”‚ โ”œโ”€โ”€ e2e.ts # E2E support file โ”‚ โ””โ”€โ”€ component.ts # Component support file โ””โ”€โ”€ downloads/ # Downloaded files during tests cypress.config.ts # Main configuration

Quick Reference

TopicFileSetup processsetup.mdMemory templatememory-template.mdSelectors & queriesselectors.mdCustom commandscommands.mdNetwork & APInetwork.mdCI/CD configurationci.md

1. Selectors: data-testid First

// โœ… Resilient โ€” survives refactors cy.get('[data-testid="submit-btn"]') cy.get('[data-cy="user-list"]') // โŒ Fragile โ€” breaks on style/structure changes cy.get('.btn-primary.submit') cy.get('#root > div > form > button:nth-child(3)') cy.get('button').contains('Submit') // OK for text, not structure Priority order: data-testid > data-cy > aria-* > text content > CSS selectors.

2. Never Use Fixed Waits

// โŒ Flaky and slow cy.wait(3000) cy.get('.loader').should('exist') cy.wait(2000) // โœ… Wait for actual state cy.get('.loader').should('not.exist') cy.get('[data-testid="results"]').should('be.visible') cy.intercept('GET', '/api/users').as('getUsers') cy.wait('@getUsers')

3. Intercept Network Requests

// Setup intercepts BEFORE triggering actions cy.intercept('POST', '/api/login', { statusCode: 200, body: { token: 'abc' } }).as('login') cy.get('[data-testid="login-btn"]').click() cy.wait('@login')

4. One Assertion Focus per Test

// โœ… Clear failure message it('shows error on invalid email', () => { cy.get('[data-testid="email"]').type('invalid') cy.get('[data-testid="submit"]').click() cy.get('[data-testid="email-error"]').should('contain', 'Valid email required') }) // โŒ Multiple concerns โ€” unclear which failed it('validates the entire form', () => { // Tests 5 different validation rules })

5. Commands for Repeated Actions

// cypress/support/commands.ts Cypress.Commands.add('login', (email: string, password: string) => { cy.session([email, password], () => { cy.visit('/login') cy.get('[data-testid="email"]').type(email) cy.get('[data-testid="password"]').type(password) cy.get('[data-testid="submit"]').click() cy.url().should('include', '/dashboard') }) }) // Usage cy.login('user@example.com', 'password123')

6. Fixtures for Test Data

// cypress/fixtures/user.json { "validUser": { "email": "test@example.com", "password": "Test123!" }, "adminUser": { "email": "admin@example.com", "password": "Admin123!" } } cy.fixture('user').then((users) => { cy.login(users.validUser.email, users.validUser.password) })

7. Isolation: Reset State Before Tests

beforeEach(() => { cy.intercept('GET', '/api/notifications', { body: [] }) cy.clearCookies() cy.clearLocalStorage() // Or: cy.task('db:seed') if using database reset })

Common Traps

TrapConsequenceFixcy.wait(ms) fixed delaysFlaky tests, slow CIUse cy.intercept().as() + cy.wait('@alias')CSS selectors for actionsBreak on redesignUse data-testid attributesTest interdependenceOne failure cascadesEach test must setup its own stateAsserting too earlyFalse positivesChain .should() to auto-retryForgetting baseUrlHardcoded URLs everywhereSet baseUrl in configSkipping viewport testsMobile bugs in prodAdd cy.viewport() testsIgnoring retry-abilityFlaky assertionsUse Cypress queries, not jQuery

Time Travel

Click any command in the Command Log to see DOM snapshot at that moment.

Pause and Step

cy.get('[data-testid="item"]').then(($el) => { debugger // Opens DevTools }) // Or cy.pause() // Pause execution, step manually

Console Debugging

cy.get('[data-testid="items"]') .should('have.length.gt', 0) .then(($items) => { console.log('Found items:', $items.length) })

cypress.config.ts Essentials

import { defineConfig } from 'cypress' export default defineConfig({ e2e: { baseUrl: 'http://localhost:3000', viewportWidth: 1280, viewportHeight: 720, defaultCommandTimeout: 10000, requestTimeout: 10000, retries: { runMode: 2, openMode: 0 }, video: false, // Enable for CI debugging screenshotOnRunFailure: true, setupNodeEvents(on, config) { // Plugins here }, }, component: { devServer: { framework: 'react', // or 'vue', 'angular', etc. bundler: 'vite', // or 'webpack' }, }, })

TypeScript Support

// cypress/support/commands.ts declare global { namespace Cypress { interface Chainable { login(email: string, password: string): Chainable<void> getByTestId(testId: string): Chainable<JQuery<HTMLElement>> } } } Cypress.Commands.add('getByTestId', (testId: string) => { return cy.get(`[data-testid="${testId}"]`) })

External Endpoints

This skill does not call external APIs. Cypress runs entirely locally or in your own CI environment.

Security & Privacy

Data that stays local: All test code and fixtures remain in project directory Cypress runs locally or in your own CI environment This skill does NOT: Send data to external services Require API keys or authentication Access files outside project directory Note: Cypress Cloud (optional, paid) can receive test results if configured with CYPRESS_RECORD_KEY. This skill does not configure or recommend it.
