Control the user's currently open Chrome tab through the Playwriter CLI (no new browser launch). Use when you need to inspect live UI state, run scripted browser actions, capture console output, or reproduce frontend issues directly in the user's tab.
Trace every user-facing button/touchpoint through its full state change sequence to find bugs where functions individually work but cancel each other out, produce wrong final state, or leave the UI in an inconsistent state. Use when: systematic debugging found no bugs but users report broken buttons, or after any major refactor touching shared state stores.
Browser DevTools extension for debugging HTMX applications with request inspection, element tracking, event timeline, swap visualization, and error detection
Remap the function_id:pc_index to the original source code position by provided debug info json file.
Used for front-end JavaScript reverse engineering with js-reverse-mcp, applicable to signature chain positioning, page observation and forensics, runtime sampling, local environment patching and reproduction, and evidence-based output. Prioritizes adaptation to js-reverse_* tools in the current environment; link with jshookmcp when stronger browser/CDP/Hook capabilities are required.
Automates Chrome browser workflows for testing web apps, debugging with console/network logs, extracting data, filling forms, and interacting with authenticated web applications (Google Docs, Gmail, Notion). Use when testing local web apps, debugging frontend issues, automating data entry, scraping web content, or working with authenticated services. Triggers on "test my web app", "check the console", "fill this form", "extract data from [URL]", "automate [browser task]", "open [authenticated app]", or debugging web application issues. Works with Chrome via Claude in Chrome extension (MCP tools: navigate, click, form_input, read_console_messages, read_network_requests, tabs_context_mcp, gif_creator).
Use Chrome DevTools MCP through UXC over local stdio for page navigation, DOM/a11y snapshots, network inspection, console inspection, and performance tooling, with a live-browser autoConnect default and optional browserUrl or isolated fallback modes.
Provides exact patterns for diagnosing and fixing automatic batching regressions in React 18 class components. Use this skill whenever a class component has multiple setState calls in an async method, inside setTimeout, inside a Promise .then() or .catch(), or in a native event handler. Use it before writing any flushSync call - the decision tree here prevents unnecessary flushSync overuse. Also use this skill when fixing test failures caused by intermediate state assertions that break after React 18 upgrade.
Setup Sentry in React apps. Use when asked to add Sentry to React, install @sentry/react, or configure error monitoring for React applications.
Browser automation toolkit using Playwright MCP for testing web applications. Use when asked to navigate pages, click elements, fill forms, take screenshots, verify UI components, check console logs, debug frontend issues, or validate responsive design. Supports live browser interaction and accessibility snapshots.
Frontend website debugging toolkit using Chrome DevTools Protocol with Playwright/WebKit fallbacks. Use this skill when: (1) Debugging CSS, HTML, or JavaScript issues on a webpage, (2) Taking screenshots to verify visual changes, (3) Inspecting DOM structure or console errors, (4) Testing responsive layouts, (5) Extracting selectors for automation, (6) Self-debugging frontend work Claude has created, (7) User says "debug this page", "check my site", "why doesn't this look right", or "fix the frontend". Supports Chrome (primary) and Safari/WebKit (via Playwright). Designed for agent-driven debugging loops.
Frontend debugging team using Chrome DevTools MCP. Dual-mode -- feature-list testing or bug-report debugging. Covers reproduction, root cause analysis, code fixes, and verification. CSV wave pipeline with conditional skip and iteration loops.
