SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires playwright, yaml, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill drastically reduces the token cost and time associated with debugging frontend web applications by capturing browser state once and allowing for multiple, efficient local queries.

Core Features & Use Cases

  • Token-Efficient Debugging: Captures snapshots of page state (DOM, console logs, network requests, accessibility tree) to disk, enabling fast, local analysis without re-rendering or re-parsing.
  • Comprehensive Analysis: Provides tools to analyze console logs, network activity, and accessibility trees, as well as capture performance traces.
  • Use Case: When a user reports a bug on a web page, this Skill can capture the exact state of the page, allowing an AI to quickly diagnose console errors, network failures, or UI issues without repeatedly loading the page.

Quick Start

Use the uisnap skill to capture the current state of https://example.com.

FAQPage Schema
How do I debug frontend browser state without consuming too many tokens?▼

Capture browser state to disk for token-efficient debugging by snapshotting DOM elements, console logs, and network requests once, then querying them locally without re-rendering the page.

Can I capture network requests and console logs using Playwright for UI debugging?▼

Yes, using Playwright you can capture network requests and console logs. The captured browser state is saved to disk, enabling fast local analysis of frontend issues without repeatedly loading the web page.

What is the best way to profile frontend performance using Chrome traces in automated tests?▼

Profile frontend performance by capturing Chrome traces via browser automation. This enables advanced diagnostics by recording execution flows and identifying bottlenecks directly from the automated test environment.

Does this browser automation approach work for analyzing accessibility trees?▼

Yes, browser automation supports analyzing accessibility trees. It snapshots the semantic structure of the page to disk, allowing you to query and audit UI compliance efficiently without re-parsing the live DOM.

How do I run custom scripts for advanced diagnostics on a captured web page?▼

Execute custom scripts directly within the browser automation context to perform advanced diagnostics. This allows you to evaluate specific page conditions and interact with elements on the captured browser state.

Why does frontend debugging take so long when repeatedly loading a page in a browser?▼

Repeatedly loading a page for frontend debugging wastes time by re-rendering and re-parsing. Capturing the browser state once to disk eliminates this overhead, allowing multiple fast local queries against the snapshot.
