Visual UI testing expert using Playwright MCP for browser automation. Use when testing responsive layouts, verifying UI changes, checking breakpoints, debugging visual/CSS issues, or validating component rendering. Triggers on "test UI", "check layout", "verify design", "responsive", "breakpoint", "visual test", "screenshot".
Use at session start - establishes Shannon Framework workflows including mandatory 8D analysis before implementation, NO MOCKS testing enforcement, wave-based execution for complexity >=0.50, and automatic Serena MCP checkpointing. Prevents under-estimation and ensures quantitative rigor. Trigger keywords: shannon, specification, complexity, wave, checkpoint, functional testing.
Kotlin testing with JUnit 5, MockK, Spring test slices, and fast feedback commands. Provides single test execution, incremental builds, and JetBrains MCP integration for rapid TDD cycles. Use when writing tests for Kotlin/Spring code, running specific tests, or debugging test failures.
Use when testing frontend applications. AI-assisted browser testing with Playwright MCP. Fast, deterministic, no vision models needed.
Add an MCP integration section (tools, auth, error handling, observability, tests) to an existing spec.
Browser automation for testing IntelliFill. Replaces puppeteer MCP to save ~4.8k tokens.
Local Python-based browser automation toolkit using Playwright. Provides command-line tools for navigating, interacting with, and testing web applications without using MCP protocols. Supports clicking, typing, hovering, screenshots, content extraction, and JavaScript execution.
Playwright E2E testing patterns. Trigger: When writing E2E tests - Page Objects, selectors, MCP workflow.
Verify web application changes work by launching the app stack and testing in a real browser. This skill should be used when the user asks to "verify the change", "test in browser", "check if it works", or after completing a PR to validate the implementation. Requires Playwright MCP server. MUST exit if Playwright MCP is unavailable.
Automate browser interactions with Playwright MCP. Use for web scraping, form filling, testing, or any browser-based automation tasks.
Browser automation using Playwright MCP. Navigate websites, fill forms, click elements, take screenshots, and extract data. Use for web browsing, form submission, web scraping, or UI testing. NOT for static content (use curl/wget).
Debug failing Playwright E2E tests by analyzing error messages, stack traces, screenshots, and Playwright traces. Provides actionable solutions for common test failures including timeouts, selector issues, race conditions, and unexpected behaviors. Optionally uses Playwright MCP for live debugging.
DEPRECATED - This skill references MCP servers that no longer exist in the codebase. The CodebaseDocumentation server was archived during MCP cleanup. Use native file reading tools (view_file, grep_search) for documentation access.
Use when optimizing website performance. Run Google Lighthouse audits via MCP to measure metrics, identify bottlenecks, and iterate on improvements.
This skill should be used when the user asks for "MCP examples", "real-world patterns", "code search patterns", "browser proxy patterns", "process management patterns", "show me examples", or wants to see actual implementations from lci, agnt, or other real MCPs.
Guide for implementing Cloudflare Browser Rendering - a headless browser automation API for screenshots, PDFs, web scraping, and testing. Use when automating browsers, taking screenshots, generating PDFs, scraping dynamic content, extracting structured data, or testing web applications. Supports REST API, Workers Bindings (Puppeteer/Playwright), MCP servers, and AI-powered automation. (project)
