App Screenshots

app-screenshots

A Claude Code skill that generates annotated screenshot documentation for any web app or live website. Point it at your local dev server **or** any public URL (otto.de, github.com, etc.) and get a markdown file with screenshots showing every page, with red circles, arrows, and labels highlighting key UI elements.

What it does

1. Local apps: auto-detects and starts your dev server (pnpm dev, npm run dev, etc.) Live sites: navigates directly to the URL, handles cookie banners and popups
2. Discovers all pages from the site's navigation
3. Takes screenshots of each page with SVG annotations injected via agent-browser
4. Generates a single markdown doc with all screenshots and descriptions

Example prompts

"Screenshot the app"
"Document otto.de with screenshots"
"Give me a visual guide of the dashboard"
"Describe the search feature on amazon.de with screenshots"
"Screenshot my app's checkout flow"

Example output

# otto.de - Visual Guide

**URL:** https://www.otto.de
**Date:** 2026-03-24
