Screenshots

Generate marketing-quality screenshots of your app using Playwright directly. Screenshots are captured at true HiDPI (2x retina) resolution using deviceScaleFactor: 2.

When to Use This Skill

Use this skill when:

  • •User wants to create screenshots for Product Hunt
  • •Creating screenshots for social media
  • •Generating images for landing pages
  • •Creating documentation screenshots
  • •User requests marketing-quality app screenshots

Prerequisites

Playwright must be available. Check for it:

bash
npx playwright --version 2>/dev/null || npm ls playwright 2>/dev/null | grep playwright

If not found, inform the user:

Playwright is required. Install it with: npm install -D playwright or npm install -D @playwright/test

Step 1: Determine App URL

If $1 is provided, use it as the app URL.

If no URL is provided:

  1. •Check if a dev server is likely running by looking for package.json scripts
  2. •Use AskUserQuestion to ask the user for the URL or offer to help start the dev server

Common default URLs to suggest:

  • •http://localhost:3000 (Next.js, Create React App, Rails)
  • •http://localhost:5173 (Vite)
  • •http://localhost:4000 (Phoenix)
  • •http://localhost:8080 (Vue CLI, generic)

Step 2: Gather Requirements

Use AskUserQuestion with the following questions:

Question 1: Screenshot count

  • •Header: "Count"
  • •Question: "How many screenshots do you need?"
  • •Options:
    • •"3-5" - Quick set of key features
    • •"5-10" - Comprehensive feature coverage
    • •"10+" - Full marketing suite

Question 2: Purpose

  • •Header: "Purpose"
  • •Question: "What will these screenshots be used for?"
  • •Options:
    • •"Product Hunt" - Hero shots and feature highlights
    • •"Social media" - Eye-catching feature demos
    • •"Landing page" - Marketing sections and benefits
    • •"Documentation" - UI reference and tutorials

Question 3: Authentication

  • •Header: "Auth"
  • •Question: "Does the app require login to access the features you want to screenshot?"
  • •Options:
    • •"No login needed" - Public pages only
    • •"Yes, I'll provide credentials" - Need to log in first

If user selects "Yes, I'll provide credentials", ask follow-up questions:

  • •"What is the login page URL?" (e.g., /login, /sign-in)
  • •"What is the email/username?"
  • •"What is the password?"

The script will automatically detect login form fields using Playwright's smart locators.

Step 3: Analyze Codebase for Features

Thoroughly explore the codebase to understand the app and identify screenshot opportunities.

3.1: Read Documentation First

Always start by reading these files to understand what the app does:

  1. •

    README.md (and any README files in subdirectories) - Read the full README to understand:

    • •What the app is and what problem it solves
    • •Key features and capabilities
    • •Screenshots or feature descriptions already documented
  2. •

    CHANGELOG.md or HISTORY.md - Recent features worth highlighting

  3. •

    docs/ directory - Any additional documentation about features

3.2: Analyze Routes to Find Pages

Read the routing configuration to discover all available pages:

FrameworkFile to ReadWhat to Look For
Next.js App Routerapp/ directory structureEach folder with page.tsx is a route
Next.js Pages Routerpages/ directoryEach file is a route
Railsconfig/routes.rbRead the entire file for all routes
React RouterSearch for createBrowserRouter or <RouteRoute definitions with paths
Vue Routersrc/router/index.js or router.jsRoutes array with path definitions
SvelteKitsrc/routes/ directoryEach folder with +page.svelte is a route
Remixapp/routes/ directoryFile-based routing
Laravelroutes/web.phpRoute definitions
Djangourls.py filesURL patterns
ExpressSearch for app.get, router.getRoute handlers

Important: Actually read these files, don't just check if they exist. The route definitions tell you what pages are available for screenshots.

3.3: Identify Key Components

Look for components that represent screenshottable features:

  • •Dashboard components
  • •Feature sections with distinct UI
  • •Forms and interactive inputs
  • •Data visualizations (charts, graphs, tables)
  • •Modals and dialogs
  • •Navigation and sidebars
  • •Settings panels
  • •User profile sections

3.4: Check for Marketing Assets

Look for existing marketing content that hints at key features:

  • •Landing page components (often in components/landing/ or components/marketing/)
  • •Feature list components
  • •Pricing tables
  • •Testimonial sections

3.5: Build Feature List

Create a comprehensive list of discovered features with:

  • •Feature name (from README or component name)
  • •URL path (from routes)
  • •CSS selector to focus on (from component structure)
  • •Required UI state (logged in, data populated, modal open, specific tab se
